Mechanisms of bronchoprotection by anesthetic induction agents: propofol versus ketamine. (1/1952)

BACKGROUND: Propofol and ketamine have been purported to decrease bronchoconstriction during induction of anesthesia and intubation. Whether they act on airway smooth muscle or through neural reflexes has not been determined. We compared propofol and ketamine to attenuate the direct activation of airway smooth muscle by methacholine and limit neurally mediated bronchoconstriction (vagal nerve stimulation). METHODS: After approval from the institutional review board, eight sheep were anesthetized with pentobarbital, paralyzed, and ventilated. After left thoracotomy, the bronchial artery was cannulated and perfused. In random order, 5 mg/ml concentrations of propofol, ketamine, and thiopental were infused into the bronchial artery at rates of 0.06, 0.20, and 0.60 ml/min. After 10 min, airway resistance was measured before and after vagal nerve stimulation and methacholine given via the bronchial artery. Data were expressed as a percent of baseline response before infusion of drug and analyzed by analysis of variance with significance set at P< or =0.05. RESULTS: Systemic blood pressure was not affected by any of the drugs (P>0.46). Baseline airway resistance was not different among the three agents (P = 0.56) or by dose (P = 0.96). Infusion of propofol and ketamine into the bronchial artery caused a dose-dependent attenuation of the vagal nerve stimulation-induced bronchoconstriction to 26+/-11% and 8+/-2% of maximum, respectively (P<0.0001). In addition, propofol caused a significant decrease in the methacholine-induced bronchoconstriction to 43+/-27% of maximum at the highest concentration (P = 0.05) CONCLUSIONS: The local bronchoprotective effects of ketamine and propofol on airways is through neurally mediated mechanisms. Although the direct effects on airway smooth muscle occur at high concentrations, these are unlikely to be of primary clinical relevance.  (+info)

Bioavailability and metabolism of hydroquinone after intratracheal instillation in male rats. (2/1952)

The purpose of this study was to investigate the rate and extent of hydroquinone (HQ) absorption and first pass metabolism in the lungs of male rats in vivo. [14C]HQ in physiological saline was administered intratracheally via an indwelling endotracheal tube to simulate inhalation exposure to HQ dust. The bioavailability of HQ was determined by blood sampling simultaneously at arterial and venous sites beginning immediately after administration to conscious rats. Pulmonary absorption and metabolism, and systemic metabolism and elimination were determined by chromatographic analysis of parent compound and metabolites in blood samples after intratracheal administration of [14C]HQ at 0.1, 1.0, and 10 mg/kg. Pulmonary absorption of HQ was found to be very rapid with [14C]HQ detectable in arterial blood, and to a lesser extent in venous blood, within 5 to 10 s after dose administration. Only [14C]HQ was detected in the initial (5-10 s) arterial blood samples at all dose levels, indicating that pulmonary metabolism of HQ was not extensive. However, later blood samples (45-720 s) indicated rapid metabolism and elimination of the parent compound and metabolites after intratracheal absorption. The elimination half-life from the 0.1 mg/kg dose was allometrically scaled to human proportions and used to estimate the steady-state (maximum) human blood concentrations of HQ resulting from presupposed workplace exposures. The estimates indicated minimal levels of HQ in human blood after respiratory exposures of greater than 1 h at 0.1 or 2.0 mg/m3; these levels were less than background concentrations of HQ detected in human blood in previous studies.  (+info)

Inhalation exposure of animals. (3/1952)

Relative advantages and disadvantages and important design criteria for various exposure methods are presented. Five types of exposures are discussed: whole-body chambers, head-only exposures, nose or mouth-only methods, lung-only exposures, and partial-lung exposures. Design considerations covered include: air cleaning and conditioning; construction materials; losses of exposure materials; evenness of exposure; sampling biases; animal observation and care; noise and vibration control, safe exhausts, chamber loading, reliability, pressure fluctuations; neck seals, masks, animal restraint methods; and animal comfort. Ethical considerations in use of animals in inhalation experiments are also discussed.  (+info)

Correlating fibreoptic nasotracheal endoscopy performance and psychomotor aptitude. (4/1952)

We have investigated the correlation between the scores attained on computerized psychometric tests, measuring psychomotor and information processing aptitudes, and learning fibreoptic endoscopy with the videoendoscope. Sixteen anaesthetic trainees performed two adaptive tracking tasks (ADTRACK 2 and ADTRACK 3) and one information management task (MAZE) from the MICROPAT testing system. They then embarked on a standardized fibreoptic training programme during which they performed 15 supervised fibreoptic nasotracheal intubations on anaesthetized oral surgery patients. There was a significant correlation between the means of the 15 endoscopy times and both ADTRACK 2 (r = -0.599, P = 0.014) and ADTRACK 3 (r = -0.589, P = 0.016) scores. The correlation between the means of the 15 endoscopy times and MAZE scores was not significant. The ratios of the mean endoscopy time for the last seven endoscopies to the mean endoscopy time for the first seven endoscopies were not significantly correlated with ADTRACK 2, ADTRACK 3 or MAZE scores. Psychomotor abilities appeared to be determinants of trainees' initial proficiency in endoscopy, but did not appear to be determinants of trainees' rates of progress during early fibreoptic training.  (+info)

Evaluation of routine tracheal extubation in children: inflating or suctioning technique? (5/1952)

We studied prospectively the effects of the technique of tracheal extubation on arterial haemoglobin oxygen saturation (SpO2) in 120 ASA I-III children, mean age 5.3 (range 0.25-16.9) yr. At completion of surgery, tracheal extubation was performed when spontaneous ventilation had resumed, children were fully awake and SpO2 was 99-100%. Children were allocated randomly to receive a single lung inflation manoeuvre with 100% oxygen before tracheal extubation (group I; n = 59) or to have the tracheal tube removed while applying suction through the tube (group S; n = 61). SpO2 was monitored during the first 5 min after tracheal extubation in the operating room. Supplementary oxygen was given if SpO2 decreased to less than 92%. The time between tracheal extubation and decrease in SpO2 to 92% (T92) was recorded. Children in group S required oxygen administration more frequently after tracheal extubation than those in group I (65.6% vs 45.8%; P = 0.04), and had a three-fold shortening of T92 (mean 25 (SD 19) s vs 85 (63) s; P = 0.0001). These effects were more pronounced in children less than 4 yr of age compared with older children. We conclude that tracheal extubation greatly impaired oxygenation and therefore administration of oxygen was appropriate. This impairment was more marked when suction was used, and in young children. Lung inflation with 100% oxygen before removal of the tracheal tube is advised before routine tracheal extubation in children.  (+info)

Effect of remifentanil on the auditory evoked response and haemodynamic changes after intubation and surgical incision. (6/1952)

We have observed the effect of intubation and incision, as measured by the auditory evoked response (AER) and haemodynamic variables, in 12 patients undergoing hernia repair or varicose vein surgery who received remifentanil as part of either an inhaled anaesthetic technique using isoflurane or as part of a total i.v. technique using propofol. Anaesthesia was induced with remifentanil 1 microgram kg-1 and propofol, neuromuscular block was achieved with atracurium 0.6 mg kg-1 before intubation, and anaesthesia was maintained with a continuous infusion of remifentanil in combination with either a continuous infusion of propofol or inhaled isoflurane. The AER and haemodynamic variables were measured before and after intubation and incision. The effects of intubation and incision on the AER and haemodynamic variables were not significantly different between the remifentanil-propofol and remifentanil-isoflurane groups. However, the study had a low power for this comparison. When the data for the two anaesthetic combinations were pooled, the only significant effects were increases in diastolic arterial pressure and heart rate immediately after intubation; these were not seen 5 min after intubation. There were no cardiovascular responses to incision. There were no significant changes in the AER after intubation or incision.  (+info)

Large goitre causing difficult intubation and failure to intubate using the intubating laryngeal mask airway: lessons for next time. (7/1952)

A 63-yr-old woman was anaesthetized for sub-total thyroidectomy. The thyroid gland was large, deviating the trachea to the right and causing 30% tracheal narrowing at the level of the suprasternal notch. Mask ventilation was easy but laryngoscopy was Cormack and Lehane grade 3. Despite being able to see the tip of the epiglottis, tracheal intubation was impossible. An intubating laryngeal mask was inserted and although the airway was clear and ventilation easy, it was not possible to intubate the trachea either blindly or with the fibreoptic bronchoscope. Tracheal intubation was eventually achieved using a 6.5-mm cuffed oral tracheal tube via a size 4 laryngeal mask under fibreoptic control. We describe the case in detail and discuss the use of the intubating laryngeal mask, its potential limitations and how to optimize its use in similar circumstances.  (+info)

The presence and sequence of endotracheal tube colonization in patients undergoing mechanical ventilation. (8/1952)

Endotracheal tube colonization in patients undergoing mechanical ventilation was investigated. In the first part of this prospective study, the airway access tube was examined for the presence of secretions, airway obstruction and bacterial colonization, in cases undergoing extubation or tube change. In the second part of the study, the sequence of oropharyngeal, gastric, respiratory tract and endotracheal tube colonization was investigated by sequential swabbing at each site twice daily for 5 days in consecutive noninfected patients. In the first part, it was noted that all airway access tubes of cases undergoing extubation had secretions lining the interior of the distal third of the tube which were shown on scanning electron microscopy to be a biofilm. Gram-negative micro-organisms were isolated from these secretions in all but three cases. In the second part, it was noted that the sequence of colonization in patients undergoing mechanical ventilation was the oropharynx (36 h), the stomach (3660 h), the lower respiratory tract (60-84 h), and thereafter the endotracheal tube (60-96 h). Nosocomial pneumonia occurred in 13 patients and in eight cases identical organisms were noted in lower respiratory tract secretions and in secretions lining the interior of the endotracheal tube. The endotracheal tube of patients undergoing mechanical ventilation becomes colonized rapidly with micro-organisms commonly associated with nosocomial pneumonia, and which may represent a persistent source of organisms causing such infections.  (+info)

Definition of Rapid Sequence Intubation in the Financial Dictionary - by Free online English dictionary and encyclopedia. What is Rapid Sequence Intubation? Meaning of Rapid Sequence Intubation as a finance term. What does Rapid Sequence Intubation mean in finance?
Orotracheal intubation following general anesthesia requires blades to be performed. The risk of patients contamination with infectious agents related to reusable metal blades leads to promote single-use blades. Some of these latter are plastic and this material may need more strength to lift the jaw and expose the larynx before orotracheal intubation. Sometimes, change of blade, from plastic to metal, during the procedure is necessary to increase the larynx exposure. This change of blade may increase the frequency of sore throat following orotracheal intubation.. Consequently, the study hypothesis is an increase of both sore throat intensity and frequency with the plastic blades compared with the metal blades.. The primary purpose of the present study is to compare the impact of these two types of blades, metal versus plastic, on sore throat intensity and frequency following scheduled orotracheal intubation for general anesthesia ...

BACKGROUND:This retrospective study was conducted at a single center in China and aimed to compare rocuronium with succinylcholine for rapid sequence induction intubation in the Emergency Department of a hospital. MATERIAL AND METHODS:An orotracheal intubation procedure was performed in a total of 267 patients by direct laryngoscopy using an intravenous bolus injection of 1 mg/kg of succinylcholine (n=141; SY group) or 1.2 mg/kg of rocuronium (n=126; RM group) for a rapid sequence induction in the emergency department. The success of orotracheal intubation was evaluated by a capnography curve. The modified Cormack-Lehane score was used to grade the direct laryngoscopy. RESULTS:There was no statistically significant difference in numbers of patients with successful first-attempt orotracheal intubation between the groups (112 vs. 87, P=0.067). Fewer intubation failures under direct laryngoscopy were reported in the SY group than in the RM group (23 [16%] vs. 34 [27%], P=0.037). The number of intubation
Airway management is one of the most important skills for an emergency department practitioner to master because failure to secure an adequate airway can quickly lead to death or disability. Endotracheal intubation using rapid sequence intubation (RSI) is the cornerstone of emergency airway management.
OBJECTIVE. Endotracheal intubation of newborn infants is a mandatory competence for many pediatric trainees. The Neonatal Resuscitation Program recommends a 20-second limit for intubation attempts. Intubation attempts by junior doctors are frequently unsuccessful, and many infants are intubated between 20 and 30 seconds without apparent adverse effect. Little is known about the proficiency of more senior medical staff, the time taken to determine endotracheal tube (ETT) position, or the effects of attempted intubation on infants heart rate (HR) and oxygen saturation (Spo2) in the delivery room (DR). The objectives of this study were to determine (1) the success rates and duration of intubation attempts during DR resuscitation, (2) whether experience is associated with greater success rates and shorter time taken to intubate, (3) the time taken to identify ETT position after intubation, and (4) the frequency with which infants deteriorated during intubation attempts and the time at which this ...
Background: Etomidate is the standard induction agent used during rapid sequence intubation (RSI) in the emergency department (ED). Etomidate shortages require providers to utilize alternative agents. The purpose of this study is to compare the safety and procedural outcomes of propofol and etomidate for RSI in the ED. Methods: This was a retrospective chart review of adult patients in the ED who received propofol or etomidate for induction during RSI. The main endpoint was hypotension, defined as a systolic blood pressure | 90 mmHg or diastolic blood pressure | 60 mmHg, within the first hour of intubation. Time to intubation, intensive care unit length of stay, hospital length of stay, and in-hospital mortality were also evaluated. Results: Two hundred and seventy five patient charts were reviewed. Of the 98 patients included, 43 patients received propofol and 55 patients received etomidate. Propofol was associated with an increased incidence of hypotension within the first hour of intubation (65.1% vs

In advanced airway management, rapid sequence induction (RSI) - also described as rapid sequence intubation or as rapid sequence induction and intubation (RSII) - is a special process for endotracheal intubation that is used where the patient is at a high risk of pulmonary aspiration or impending airway compromise. It differs from other forms of general anesthesia induction in that artificial ventilation is generally not provided from the time the patient stops breathing (when drugs are given) until after intubation has been achieved. This minimizes insufflation of air into the patients stomach, which might otherwise provoke regurgitation. Classic RSI involves pre-filling the patients lungs with a high concentration of oxygen gas, followed by applying cricoid pressure, administering rapid-onset sedative or hypnotic and neuromuscular-blocking drugs that induce prompt unconsciousness and paralysis, inserting an endotracheal tube with minimal delay, and then releasing the cricoid pressure. ...

Trachway video intubating stylet allows for optimization of electromyographic endotracheal tube placement for monitored thyroidectomy
An apparatus for endotracheal intubation comprises a suction stylet (10) telescopically disposed within an endotracheal tube (30) such that the suction stylet (10) is operative to aspirate fluids from the vicinity of the distal end (16) of the endotracheal tube. The apparatus further comprises a connector for releasably axially fixing the suction stylet with respect to the endotracheal tube during intubation. The suction stylet (10) and endotracheal tube (30) are advanced down the trachea simultaneously, the suction stylet (10) aspirating unwanted oral secretions from the operators field of view during intubation. Once the trachea is intubated, the connector is disconnected and the suction stylet is withdrawn, leaving the endotracheal tube in place. A method for endotracheal intubation is also disclosed in which a suction stylet (10) is telescopically disposed within an endotracheal tube (30). The suction stylet and endotracheal tube are advanced simultaneously through the trachea, aspirating unwanted

Introduction: Filling tracheal tube cuff (TTC) after intubation is necessary to provide a safe airway in intubated patients. On the other hand, excessive increase or decrease in the pressure of TTCs balloon leads into the dangerous complications such as necrosis and/or aspiration. Accordingly, in the present study, we tried to evaluate the most two common fixed volume and pilot balloon palpitation methods to control TTC pressure. Methods: In a prospective cross-sectional study that was carried out in the emergency department of Tabriz Imam Reza hospital upon 194 patients who needed intubation and from April 2015 to June 2016. The patients were randomly allocated into two equal groups. For the first the Pilot Balloon Palpation technique and for the second group 10 cc fixed volume cuff filling technique was assigned. After that, the pressure was checked with manometer and data were analyzed using SPSS software. Results: TTC pressure average in fixed volume group was 44.96±21.77 cmH2O and for
PURPOSE: Intubation in ICU strongly differs from intubation in operative rooms. The results of studies about risk factors of difficult intubation performed in operative rooms cannot therefore be extrapolated directly to ICU.. The primary purpose of this trial (cf Part Design of this registration) is other and more particularly Prognosis because it is is an assessment of risk factors of difficult airway in intensive care units.. DESIGN AND METHODOLOGY: This is an open prospective multicentric study of intubation in ICU in more than 50 centres. Consecutive intubations will be included in each centre, in order to reach the sample size required (at least 1000 procedures intubations). The usual risk factors of difficult intubation in operative rooms, the demographic parameters and the complications of intubation will be assessed, as well as survival status at 28 days. ...
Comparison of Alfentanil and Lignocaine in blunting the pressor response during endotracheal intubation. Laryngoscopy and tracheal intubation produce marked increases in heart rate and blood pressure, which is potentially dangerous in certain patients. Various pharmacological agents have been used before laryngoscopy and tracheal intubation in an attempt to attenuate the adrenergic response, but with varying degree of success. OBJECTIVE To compare the efficacy of lignocaine to alfentanil in blunting the pressor response to endotracheal intubation. DESIGN An open label comparative study. POPULATION Seventy eight ASA I and II adult patients between the ages of 18 and 65 years booked for elective surgery which requires endotracheal intubation.

The patients were randomly allocated to three groups according ...
INTRODUCTION: Postoperative sore throat is listed from the top as patients most undesirable outcome in the postoperative period. It is believed to originate from mucosal dehydration or edema, tracheal ischemia secondary to the pressure of endotracheal tube cuffs, aggressive oropharyngeal suctioning, and mucosal erosion from friction between delicate tissues and the endotracheal tube. Even if the problem was indicated in many literatures, it has never been studied in our country. The study aimed to assess prevalence and factors associated with postoperative sore throat among patients who were operated under general anesthesia with endotracheal intubation. METHODS: hospital based cross sectional study was conducted from February 25 - April 10, 2014 in Gondar University hospital. Patient interview and chart review were employed for data collection. Bivariate and multivariate logistic regressions were used to determine the association.
Background: Awake intubation is the standard of care for management of the anticipated difficult airway. The performance of awake intubation may be perceived as complex and time-consuming, potentially leading clinicians to avoid this technique of airway management. This retrospective review of awake intubations at a large academic medical center was performed to determine the average time taken to perform awake intubation, its effects on hemodynamics, and the incidence and characteristics of complications and failure. Methods: Anesthetic records from 2007 to 2014 were queried for the performance of an awake intubation. Of the 1,085 awake intubations included for analysis, 1,055 involved the use of a flexible bronchoscope. Each awake intubation case was propensity matched with two controls (1:2 ratio), with similar comorbidities and intubations performed after the induction of anesthesia (n = 2,170). The time from entry into the operating room until intubation was compared between groups. The ...
Tracheal intubation (usually simply referred to as intubation), an invasive medical procedure, is the placement of a flexible plastic catheter into the trachea. For millennia, tracheotomy was considered the most reliable (and most risky) method of tracheal intubation. By the late 19th century, advances in the sciences of anatomy and physiology, as well as the beginnings of an appreciation of the germ theory of disease, had reduced the morbidity and mortality of this operation to a more acceptable rate. Also in the late 19th century, advances in endoscopic instrumentation had improved to such a degree that direct laryngoscopy had finally become a viable means to secure the airway by the non-surgical orotracheal route. Nasotracheal intubation was not widely practiced until the early 20th century. The 20th century saw the transformation of the practices of tracheotomy, endoscopy and non-surgical tracheal intubation from rarely employed procedures to essential components of the practices of ...
Methods: HFNO of 60 L.min−1 at an inspiratory oxygen fraction of 1 was delivered 4 min before laryngoscopy and maintained until the patient was intubated, and correct intubation was verified by the appearance of the end-tidal CO2 (EtCO2) waveform. Transcutaneous oxygenation (SpO2), heart rate and non-invasive mean arterial pressure were monitored at baseline (T0), after 4 min on HFNO (T1) and at the time of laryngoscopy (T2) and endotracheal intubation (ETI) (T3). An SpO2 of ...
The results of using a prewarmed tube for nasotracheal intubation are variable.1-3 Although studies in adults suggest reduced bleeding, its efficacy in pediatric patients seems to be poor.1-4 In the control group in the study by Watt et al .,1 where tracheal intubation was achieved by using a tube at room temperature, the incidence of bleeding was 56%, significantly higher than in the control group of Elwood et al .,4 wherein a thermosoftened tube was used and the incidence of bleeding was only 29%. Further, although Watt et al .1 report that a 39% incidence of epistaxis in patients in whom the nasotracheal tube was carried with a thermosoftened uncuffed tube is consistent with that reported by Elwood et al .4 in their thermosoftening group (29%), it is still higher in the study of Watt et al . Considering these facts, in the study by Watt et al ., the higher incidence of bleeding in patients in whom a prewarmed tube was used can be attributed to the use of a larger tube (selected by Coles ...

Yoshihiro Hirabayashi, Norimasa Seo, Jichi Medical University, Japan 20 anesthetists performed tracheal intubations on a manikin with either an in-line head and neck position or the sniffing position. There were no differences in the success rate and the time to intubation between the two positions. The overall number of teeth clicks was lower in the in-line head and neck position than in the sniffing position (P , 0.05). The score for preference of position, on a visual analogue scale, was better for the in-line head and neck position than for the sniffing position (P , 0.01). We concluded that the in-line head and neck position was preferable for tracheal intubation with the Airtraq laryngoscope compared to the sniffing position. ...
Objective To describe a simple protocol for ventilator-assisted preoxygenation (VAPOX) prior to rapid sequence intubation in the ED using a Hamilton T1 ventilator in an effort to further reduce the incidence of transient and critical hypoxaemia. Methods Ventilator-assisted preoxygenation includes the following steps; preparation for rapid sequence intubation as per institutional protocols, including departmental checklists. Hamilton T1 ventilator is setup in non-invasive spontaneous/timed mode with settings as described. The patient is optimally positioned and nasal cannula applied with an oxygen flow rate of 15 L/min. A face mask is applied with the jaw pulled forward using a two-handed thenar eminence grip and the ventilator is started. Preoxygenation occurs for 3 min. Drugs including neuromuscular blockers are administered, while the operator ensures the airway remains patent. The ventilator transitions into Pressure Controlled Ventilation once apnoea ensues. Nasal oxygen continues until endotracheal
A malleable stylet... was placed within a 4.0 cuffed tracheal tube... and shaped like a hockey stick. A 15-6 MHZ HFL50x linear array ultrasound probe attached to a Sonosite S-nerve machine (SonoSite Inc., Bothell, WA) was lightly placed transversely on the patients neck at the level of the thyrohyoid membrane. The probe was moved caudally until a view of the vocal cords and surrounding hypopharyngeal tissue was obtained. A second provider opened the mouth and performed a jaw thrust while inserting the hockey-stick-shaped styletted tube in the midline of the patients pharynx. The tube was inserted in the midline of the pharynx under the operators direct vision, it was then advanced slowly along the tongue base at which point it was visualized to the left of the glottis on the ultrasound image. The tube was withdrawn slightly and its trajectory modified to direct it into the glottis; hypoechoic shadowing and widening of the vocal cords was noted as the tube entered the trachea, a characteristic ...

In patients undergoing emergent tracheal intubation, there is currently no universally accepted gold-standard test to confirm the location of the endotracheal tube (ETT).1 End-tidal carbon dioxide (CO2) detection is the best of the tests that are routinely utilized to confirm ETT placement, however, it has been shown to have an error rate as high as 1/10 for proper determination of ETT location in emergency intubations.2 As a result, multiple modalities are necessary to confirm ETT location, which can delay mechanical ventilation and other treatments. The lack of a single, reliable test to confirm ETT placement can potentially lead to confusion regarding the location of the tube. This confusion can result in both unrecognized esophageal intubations (false positive), as well as successful tracheal intubations that are subsequently removed (false negative), subjecting the patient to further unnecessary attempts at airway management. Both scenarios can lead to disastrous consequences.. (more…) ...

We have studied the effect of three bolus doses of remifentanil on the haemodynamic response to laryngoscopy and tracheal intubation. Using a double-blind design, 80 ASA 1 or 2 patients presenting for elective surgery received saline placebo or remifentanil 0.25, 0.5 or 1.0 microgram.kg-1 by random allocation. Anaesthesia was induced with thiopentone 5-7 mg.kg-1 and followed immediately by the study medication given as a bolus over 30s. Muscle relaxation was provided with rocuronium 0.75 mg.kg-1. The patients tracheas were intubated under direct laryngoscopy 1 min later. Noninvasive arterial blood pressure and heart rate were recorded immediately before induction of anaesthesia and then at intervals until 5 min after tracheal intubation. There was a significant increase in heart rate (p , 0.01) and systolic arterial pressure (p , 0.01) in all groups after tracheal intubation. However, this was short-lived and of a smaller magnitude in the remifentanil 1 microgram.kg-1 group in which the ...
BACKGROUND: Laryngoscopy and endotracheal intubation are known to cause increase in both arterial blood pressure and heart rate. Several strategies have been evolved to blunt the haemodynamic response to tracheal intubation but each method has its own advantages and disadvantages. Esmolol, a cardio selective Beta-1 blocking drug, can alleviate some of these problems. Esmolol, when administered parenterally, exhibits rapid onset and a short duration of action due to its rapid clearance by red blood cell esterases. Hence we conducted the present study to evaluate the efficacy and optimum time of single bolus esmolol administration in attenuating hypertensive- tachycardiac response to laryngoscopy and tracheal intubation.. MATERIALS AND METHODS: The randomized double blind prospective study was conducted in 60 patients, in the age group of 20-40 years, of both sexes, belonging to American Society of Anaesthesiologists (ASA) physical status class I or II and scheduled for elective surgery requiring ...

Prolonged time during endotracheal tube placement has been associated with poor outcomes, including cardiac arrest and death. For this reason, the accurate measurement of the duration of intubation time is an important metric in studies that evaluate interventions to improve airway outcomes. In the current study we correlated the gaps in routinely measured ventilatory parameters with duration of the intubation procedure to determine if these intervals could be used to accurately calculate the intubation time. Fifty-six random airway management encounters were video recorded along with a continuous video feed of the patient monitor. Intubation event times were measured and correlated with gap times of end-tidal carbon dioxide, airway pressure, airway flow, tidal volume, and respiratory rate defined as the disappearance of the parameter at the end of mask ventilation to the reappearance after intubation. Scatter plots were generated for intubation times versus each parameter time gap and ...
Background and Aims: The oncologists are treating cancer more aggressively, leading to increase in number of pediatric admissions to the ICU. Due to anatomical and physiological differences, pediatric patients are at high risk of complications during intubation. We evaluated the incidence of complications during intubations in pediatric patients in our ICU. Subjects and Methods: We performed retrospective analysis of complications occurring during intubation in 42 pediatric patients. All intubations were orotracheal. We recorded number of attempts at intubation, need for use of intubation adjuncts and complications during laryngoscopy and intubation. The incidence of difficult intubation, hypoxia, and severe cardiovascular collapse was also noted. Results: Complications occurred during 13 (31%) intubations. Hypoxia and severe cardiovascular collapse occurred in during 7 (16.7%) intubations each, while 4 patients (9.5%) (n=4) had cardiac arrest during intubation. Thirty three (78.6%) intubations ...
Delayed Sequence Intubation (DSI) is a procedural sedation, the procedure in this case being effective preoxygenation. Give ketamine, put them on the mask, and in 3 minutes paralyze and intubate.
For professionals, however, the bag valve mask is still the preferred ventilation method early on in cardiac arrest, Harper said. Looking at intubation success rates, Harper reported a 31 percent failure rate for prehospital intubation with about 12 percent unrecognized esophageal intubation on arrival a the hospital. Interestingly, this study showed no difference in mortality between those with failed intubation and those who were successfully intubated on arrival. Does that mean a bad tube is just as good as a good tube? In some respect this supports the idea of just working the patient longer with a BVM, Harper said ...
Stenoses of the respiratory tract are life threatening conditions of various origins. The authors give referrence on 21 patients operated for postintubation stenoses of their trachea at the IInd Surgical Clinic of the UPJŠ Medical Faculty, the Faculty Hospital of L. Pasteur in Košice, from 01. 01. 1999 to 30. 06. 2005. All patients had a tracheobronchoscopic examination and a CT examination completed prior to the procedure. Within 24 hours of their admission, 9 patients were operated, 7 underwent resection procedures and 2 patients had Montgomerys T-cannula introduced. 12 patients had their procedures planned, and were operated later than 24 hours after their admission. 10 patients underwent resections of the trachea, 2 had Montgomerys Tcannula implanted. The postoperative course following the resection of the trachea was without complications in 14 patients, 1 patient experienced transitional oedema in the anastomosis and 2 patients suffered restenoses. In this patient group, no fatal case ...
Cricoid pressure is considered to be the gold standard means of preventing aspiration of gastric content during Rapid Sequence Intubation (RSI). Its effectiveness has only been demonstrated in cadaveric studies and case reports. No randomised controlled trials comparing the incidence of gastric aspiration following emergent RSI, with or without cricoid pressure, have been performed. If improperly applied, cricoid pressure increases risk to the patient. The clinical significance of aspiration in the emergency department is unknown. This randomised controlled trial aims to; 1. Compare the application of the ideal amount of force (30 - 40 newtons) to standard, unmeasured cricoid pressure and 2. Determine the incidence of clinically defined aspiration syndromes following RSI using a fibrinogen degradation assay previously described. 212 patients requiring emergency intubation will be randomly allocated to either control (unmeasured cricoid pressure) or intervention groups (30 - 40 newtons cricoid pressure

The McGrath (R) Series 5 videolaryngoscope might reduce the incidence of unexpected difficult tracheal intubation. If it also performs as well as a standard laryngoscope during uncomplicated intubations, there would be an argument for the McGrath (R) to become the laryngoscope of choice in higher risk settings, such as rapid sequence induction by inexperienced anaesthetists. Therefore, we compared the McGrath and the Macintosh laryngoscopes during routine tracheal intubation performed by inexperienced anaesthetists.Methods. Single-blind randomized controlled trial with 120 adult patients allocated to intubation by first-year anaesthetic trainees, using a McGrath (R) or Macintosh laryngoscope. The ...
There is no CPT code for elective endotracheal intubation. Airway access is necessary for general anesthesia and is not separately reportable. CPT code 31500 describes an emergency endotracheal intubation and should not be reported for elective endotracheal intubation. Visualization of the airway is a component part of an endotracheal intubation, and CPT codes describing procedures that visualize the airway (e.g., nasal endoscopy, laryngoscopy, bronchoscopy) should not be reported with an endotracheal intubation. These CPT codes describe diagnostic and therapeutic endoscopies, and it is a misuse of these codes to report visualization of the airway for endotracheal intubation ...
Laryngeal mask airway (LMA) CTrach has an integrated fiber optic bundle and battery-powered monitor that enable viewing the larynx. The LMA CTrach is a step in the evolution of LMA Fastrach. This study assessed the feasibility of the two types of LMA in anesthetized non-paralyzed patients. This is a randomized controlled study where patients were allocated into two equal groups (n = 40 each), LMA CTrach group and LMA Fastrach group. All patients were scheduled for elective surgeries requiring intubation. General anesthesia with sevoflurane was used without the use of a neuromuscular blocking agent. The success of intubation from the first attempt and overall success rate were recorded. Also, the time to achieve ventilation, the time for complete tracheal intubation, and the time of the whole procedure were recorded, and any side effects were noticed. Tracheal intubation was successful on the first attempt in 92.5% in the LMA CTrach group and in 67.5% in the LMA Fastrach group. The success rate within
This report presents a case of a patient with multiple tooth fractures in posterior teeth that were diagnosed several months following emergency intubation.. Although it is probably not a rare complication of general anesthesia, with a reported incidence that ranges from less than 1% to more than 12% of cases, its presented characteristics extremely varies among studies (de Sousa and Mourao 2015; Vogel et al. 2009; Adolphs et al. 2011; Burton and Baker 1987).. It had been reported that generally the incidence of tooth injuries caused by intubation increases with age. In addition it had been reported that elderly patients suffer more from tooth luxation or avulsion due to age related chronic marginal periodontitis and attachment loss, and in contrast, younger patients primarily suffer from tooth fractures (Vogel et al. 2009). However, in the current case an elderly patient suffered from multiple tooth fractures without any evident luxation injuries.. Ascending aorta dissection is a tear in the ...

Awake video laryngoscopy is a novel option in airway management that is drawing more and more attention as an alternative to awake endoscopic guided intubation.Main issues: Intubation under preserved spontaneous breathing is the safest method to secure the expected difficult airway. In direct comparisons to awake flexible endoscopic intubation, awake videolaryngoscopy achieves satisfactory intubation times and a high acceptance of patients and anesthesiologists. Specific cases, in particular very limited mouth opening or sub-glottic masses, require awake flexible endoscopic intubation. Sufficient topical anesthesia and a sophisticated sedation protocol are prerequisites for successful awake video laryngoscopy.. ...
Background Supraglottic airway devices commonly are used for securing the airway during general anesthesia. Occasionally, intubation with an endotracheal tube through a supraglottic airway is indicated. Reported success rates for blind intubation range from 15 to 97%. The authors thus investigated as their primary outcome the fraction of patients who could be intubated blindly with an Air-Qsp supraglottic airway device (Mercury Medical, USA). Second, the authors investigated the influence of muscle relaxation on air leakage pressure, predictors for failed blind intubation, and associated complications of using the supraglottic airway device. Methods The authors enrolled 1,000 adults having elective surgery with endotracheal intubation. After routine induction of general anesthesia, a supraglottic airway device was inserted and patients were ventilated intermittently. Air leak pressure was measured before and after full muscle relaxation. Up to two blind intubation attempts were performed. ...
INTRODUCTION: Airway management is still a major cause of anesthesia-associated morbidity and mortality. Supraglottic devices are recommended in difficult airway management guidelines. The aim of this study was to compare the performance of the Air-Q® and the LMA Fastrach™ for fiberoptic guided tracheal intubation. METHODS: Thirty-three anesthesia trainees participated in this randomized crossover study. Time to insert the dedicated airways (insertion of the airway into the manikin and delivery of two breaths), time to tracheal intubation (fiberoptic-guided tracheal intubation), time to remove the dedicated airway (removal of the Air-Q®/LMA Fastrach™ over the tracheal tube) and the opinion of the ease of use of the anesthesia trainees were measured ...

Background Due to the frequency and risks associated with endotracheal suctioning, there is a need to examine clinical practice critically and identify clinical research to guide practice. Correct technique and preparation by the clinicians can assist to reduce the risks of adverse events and the level of discomfort for the patients. Objectives The current study aimed to investigate the effects of routine versus the minimally invasive endotracheal tube suctioning procedure on suction-related pain, airway clearance and airway trauma in patients who were intubated. Methods In this randomized clinical trial, 64 patients with intubation in the intensive care units (ICUs) of Alzahra Hospital, Isfahan, Iran, were randomly allocated to minimally invasive endotracheal tube suctioning (MIETS) and routine endotracheal tube suctioning (RETS) groups. Pain intensity was assessed immediately before, immediately after and 10 minutes after endotracheal tube suctioning (ETS). Airway clearance was defined by numbers of
Traumatic brain injury patients frequently undergo tracheal intubation. We aimed to assess current intubation practice in Europe and identify variation in practice. We analysed data from patients with traumatic brain injury included in the prospective cohort study collaborative European neurotrauma effectiveness research in traumatic brain injury (CENTER-TBI) in 45 centres in 16 European countries. We included patients who were transported to hospital by emergency medical services. We used mixed-effects multinomial regression to quantify the effects on pre-hospital or in-hospital tracheal intubation of the following: patient characteristics; injury characteristics; centre; and trauma system characteristics. A total of 3843 patients were included. Of these, 1322 (34%) had their tracheas intubated; 839 (22%) pre-hospital and 483 (13%) in-hospital. The fit of the model with only patient characteristics predicting intubation was good (Nagelkerke R2 64%). The probability of tracheal intubation ...
Introduction: Laryngoscopy and endotracheal intubation alter cardiovascular physiology both via reflex responses and physical presence of an endotracheal tube (ETT). Stress response caused by laryngoscopic endotracheal intubation may be harmful for the coronary or cerebral circulation of high-risk patients. This study aimed to evaluate the hypothesis that placement of Proseal laryngeal mask airway (PLMA) and intubating laryngeal mask airway (ILMA) are associated with less cardiovascular response than the endotracheal intubation via conventional technique. Materials and Methods: In this hospital-based, randomized, interventional study, 105 patients of the American Society of Anesthesiologists Grade II and III undergoing coronary artery bypass grafting surgery under general anesthesia were randomly allocated into three groups, that is, PLMA, ILMA, and ETT. Hemodynamic parameters such as heart rate, blood pressure, cardiac output, cardiac index, systemic vascular resistance (SVR,) and SVR index ...
In emergency settings, verification of endotracheal tube (ETT) location is important for critically ill patients. Ignorance of oesophageal intubation can be disastrous. Many methods are used for verification of the endotracheal tube location; none are ideal. Quantitative waveform capnography is considered the standard of care for this purpose but is not always available and is expensive. Therefore, this feasibility study is conducted to compare a cheaper alternative, bedside upper airway ultrasonography to waveform capnography, for verification of endotracheal tube location after intubation. This was a prospective, single-centre, observational study, conducted at the HRPB, Ipoh. It included patients who were intubated in the emergency department from 28 March 2012 to 17 August 2012. A waiver of consent had been obtained from the Medical Research Ethics Committee. Bedside upper airway ultrasonography was performed after intubation and compared to waveform capnography. Specificity, sensitivity, positive
Tracheal intubation is generally considered the best method for airway management under a wide variety of circumstances, as it provides the most reliable means of oxygenation and ventilation and the greatest degree of protection against regurgitation and pulmonary aspiration.[2] However, tracheal intubation requires a great deal of clinical experience to master[81] and serious complications may result even when properly performed.[82]. Four anatomic features must be present for orotracheal intubation to be straightforward: adequate mouth opening (full range of motion of the temporomandibular joint), sufficient pharyngeal space (determined by examining the back of the mouth), sufficient submandibular space (distance between the thyroid cartilage and the chin, the space into which the tongue must be displaced in order for the larygoscopist to view the glottis), and adequate extension of the cervical spine at the atlanto-occipital joint. If any of these variables is in any way compromised, ...

BACKGROUND: The use of cuffed tracheal tubes (TTs) in small children is still controversial. The aim of this study was to compare post-extubation morbidity and TT exchange rates when using cuffed vs uncuffed tubes in small children. METHODS: Patients aged from birth to 5 yr requiring general anaesthesia with TT intubation were included in 24 European paediatric anaesthesia centres. Patients were prospectively randomized into a cuffed TT group (Microcuff PET) and an uncuffed TT group (Mallinckrodt, Portex, Rüsch, Sheridan). Endpoints were incidence of post-extubation stridor and the number of TT exchanges to find an appropriate-sized tube. For cuffed TTs, minimal cuff pressure required to seal the airway was noted; maximal cuff pressure was limited at 20 cm H(2)O with a pressure release valve. Data are mean (SD). RESULTS: A total of 2246 children were studied (1119/1127 cuffed/uncuffed). The age was 1.93 (1.48) yr in the cuffed and 1.87 (1.45) yr in the uncuffed groups. Post-extubation stridor ...
The purpose of this study was to compare the cuff pressures of three tracheostomy tubes, MERA sofit CLEAR, Blue Line Tracheostomy Tube, and Tracheosoft. Each tracheostomy tube with an internal diameter of 7.0 mm was put into a plastic column. The cuff was then inflated with air to seal the column, and the column was filled with water. The air in the cuff was withdrawn gradually and the cuff pressure at the point of water leakage was measured. Six columns of different size were used. In columns with an internal diameter of 18â€21 mm, the water leakage pressure was lower in the following order: MERA sofit CLEAR < Tracheosoft ≤ Blue Line Tracheostomy Tube. A mongrel dog was tracheotomized, and each tracheostomy tube with an internal diameter of 7.5 mm was intubated. The cuff air was increased by 1 ml from 4 ml to 10 ml, and the intracuff pressure was then measured. The intracaff pressure of the Blue Line Tracheostomy Tube was the highest at the same cuff volume, and that of the ...
Accurate localisation of the cricoid cartilage is a key step in the successful application of cricoid pressure during rapid sequence induction. Poorly localised pressure is unlikely to confer any protective benefit to our patients and may have deleterious effects on laryngoscopy. We postulated that the use of ultrasound would greatly improve the accuracy of cricoid cartilage localisation prior to the application of cricoid pressure.
The observational study design chosen for this study enabled the group to research rare events that are difficult to investigate in a prospective randomized design. Observational data from registries and large data sets remain an effective tool to compare interventions to their associated outcomes. Work from the American Society of Anesthesiologists closed claims data set helped us determine that multiple attempts at intubation are associated with poor patient outcomes.4 Other observational studies have similarly informed the anesthesia community about strategies to manage the difficult airway. The United Kingdoms 4th National Audit Project was an enhanced observational study that prospectively examined airway management procedures across the country to capture key events in difficult airway management.5 This study group highlighted that poor airway planning, problems with aspiration, and failed rescue surgical airway management are important areas for attention. Subsequent edits to the ...

We identified 22 trials on use of a pre-procedure check-list (1 study), pre-oxygenation or apneic oxygenation (6 studies), sedatives (3 studies), neuromuscular blocking agents (1 study), patient positioning (1 study), video laryngoscopy (9 studies), and post-intubation lung recruitment (1 study). Pre-oxygenation with non-invasive ventilation (NIV) and/or high-flow nasal cannula (HFNC) showed a possible beneficial role. Post-intubation recruitment improved oxygenation while ramped position increased the number of intubation attempts and thiopental had negative hemodynamic effects. No effect was found for use of a checklist, apneic oxygenation (on oxygenation and hemodynamics), videolaryngoscopy (on number and length of intubation attempts), sedatives and neuromuscular blockers (on hemodynamics). Finally, videolaryngoscopy was associated with severe adverse effects in multiple trials ...

Literature Review:. Airway management is a cornerstone of both basic and advanced life support. Paramedics and other EMS providers frequently encounter patients who can no longer protect their own airways (traumatic brain injury, major polytrauma, intoxication and overdose) or who are experiencing impending respiratory failure (exacerbations of congestive heart failure and obstructive lung disease). In-hospital management for these patients typically includes endotracheal intubation (ETI), which provides definitive control of the airway, reduces aspiration risk, and allows for mechanical ventilatory support. Do any of these patients benefit from pre-hospital ETI? Should EMS providers intubate in the field, or should they use airway adjuncts such as bag-valve mask ventilation, supraglottic airway devices, or non-invasive positive pressure ventilation to temporize their patients during rapid transport to the hospital?. As one might expect, the data on this issue are mixed and generally poor in ...

Subclavian venous catheterization is common technique for a variety of purposes, but this procedure is associated with complications that include damage to the lung, pleura, thoracic duct, nerve and subclavian artery. We recently encountered a case of the tracheal puncture and endotracheal cuff perforation during the subclavian catheterization in a 67-year-old female who was scheduled for tracheal reconstruction. Tidal volume was escaping from around the endotracheal tube during the subclavian catheterization, however, repeated inflation of the cuff failed to maintain the necessary cuff pressure to seal the trachea. After the operation, by using the fiberoptic bronchoscope and injecting dye into the cuff, we confirmed the site of tracheal puncture and endotracheal cuff perforation which caused by the introducer needle of the central venous kit. We suggest that tracheal puncture and endotracheal cuff perforation be added to the list of complication of subclavian catheterization. This complication ...

Conventionally, nasotracheal intubation has consisted of blind nasal passage and external manipulation of the tube through the glottis (conventional technique), a technique associated with a high incidence of nasal trauma. We evaluated a novel technique for routine asleep (i.e. post‐induction) nasotracheal intubation using a bougie (bougie technique), which uses a nasopharyngeal airway to guide a paediatric bougie nasotracheally for use as a Seldinger tracheal intubation guide. Two hundred and fifty‐seven older children (, 8 years) and adults were randomly assigned to videolaryngoscopy‐assisted nasotracheal intubation using either the conventional or the bougie technique. The hypothesis was that the bougie technique would result in less nasopharyngeal trauma. The bougie technique was associated with significantly less nasopharyngeal bleeding than the conventional technique at both 60-90 s (55% vs. 68%; p = 0.033) and 5 min (51% vs. 70%; p = 0.002). The severity of bleeding was also ...

Self-directed practice using VFI software may improve the initial acquisition of fibreoptic intubation skills for anesthesia residents.
In the vast majority of cases endotracheal intubation precedes tracheostomy tube placement. The trach is generally opted for in the course of ventilation support when the patient is unable to be extubated within a period that varies from institution to institution and specialist to specialist but is usually from as quickly as 3 to as long as 30 days depending on the clinical situation and practice of the physician or institution. Endotracheal intubation carries a great many risks and complications similar to tracheostomy. It is an invasive, but not a surgically invasive procedure. Avoiding intubation is the most basic way to avoid a tracheostomy.

2017 The Association of Anaesthetists of Great Britain and Ireland Cuffed tracheal tubes are increasingly used in paediatric anaesthetic practice. This study compared tidal volume and leakage around cuffed and uncuffed tracheal tubes in children who required standardised mechanical ventilation of their lungs in the operating theatre. Children (0-16 years) undergoing elective surgery requiring tracheal intubation were randomly assigned to receive either a cuffed or an uncuffed tracheal tube. Assessments were made at five different time-points: during volume-controlled ventilation 6 ml.kg -1 , PEEP 5 cmH 2 O and during pressure-controlled ventilation 10 cmH 2 O/ PEEP 5 cmH 2 O. The pressure-controlled ventilation measurement time-points were: just before a standardised recruitment manoeuvre; just after recruitment manoeuvre; 10 min; and 30 min after the recruitment manoeuvre. Problems and complications were recorded. During volume-controlled ventilation, leakage was significantly less with cuffed ...
Endotracheal tube (ETT) cuff herniation is a rare, and often difficult to diagnose, cause of bronchial obstruction. We present a case of outside cuff herniation of an endotracheal tube that caused pulmonary right lung atelectasis. A 29-year-old man ,a case of car accident with multiple fractures, was admitted to the emergency ward and transferred to the operating room(OR) for open reduction and internal fixation (ORIF) of all fractures .The procedures were done under general anesthesia (G/A). The past medical history of the patient did not indicate any problem. Anesthesia was induced with thiopental, atracurium and then maintained by propofol and remifentanyl infusions and 100% O2 via orally inserted ETT. The patient was positioned in left lateral decubitus position for operation. Two hours after induction of anesthesia, the oxygen saturation level dropped to 85 % and the breath sounds in the right side of the chest were weakened. The chest x-ray images showed right lung atelectasis especially ...

  • Improvements in gas exchange were seen in approximately 71% of these patients, endotracheal intubation was not needed for 82%, and the standardised mortality ratio was 0.86. (hkmj.org)
  • A systematic literature search was conducted to identify interventional and observational studies where the mortality rates of adult trauma patients undergoing pre-hospital endotracheal intubation were compared to those undergoing emergency department intubation. (biomedcentral.com)
  • The median mortality rate in patients undergoing pre-hospital intubation was 48% (range 8-94%), compared to 29% (range 6-67%) in patients undergoing intubation in the emergency department. (biomedcentral.com)
  • Odds ratios were in favour of emergency department intubation both in crude and adjusted mortality, with 2.56 (95% CI: 2.06, 3.18) and 2.59 (95% CI: 1.97, 3.39), respectively. (biomedcentral.com)
  • Twelve of the twenty-one studies found a significantly higher mortality rate after pre-hospital intubation, seven found no significant differences, one found a positive effect, and for one study an analysis of the mortality rate was beyond the scope of the article. (biomedcentral.com)
  • The association between pre-hospital intubation and a higher mortality rate does not necessarily contradict the importance of the intervention, but it does call for a thorough investigation by clinicians and researchers into possible causes for this finding. (biomedcentral.com)
  • Studies that assessed in-hospital mortality (the primary review outcome), endotracheal intubation, or length of hospital stay were eligible for inclusion. (york.ac.uk)
  • For each study, the intubation rates and mortality for each treatment group were extracted. (york.ac.uk)
