An unnaturally deep or rough quality of voice.
A thin leaf-shaped cartilage that is covered with LARYNGEAL MUCOSA and situated posterior to the root of the tongue and HYOID BONE. During swallowing, the epiglottis folds back over the larynx inlet thus prevents foods from entering the airway.
A type of oropharyngeal airway that provides an alternative to endotracheal intubation and standard mask anesthesia in certain patients. It is introduced into the hypopharynx to form a seal around the larynx thus permitting spontaneous or positive pressure ventilation without penetration of the larynx or esophagus.

Management of laryngeal foreign bodies in children. (1/460)

Foreign body aspiration is one of the leading causes of accidental death in children. Food items are the most common items aspirated in infants and toddlers, whereas older children are more likely to aspirate non-food items. Laryngeal impaction of a foreign body is very rare as most aspirated foreign bodies pass through the laryngeal inlet and get lodged lower down in the airway. Two rare cases of foreign body aspiration with subglottic impaction in very young children (under 2 years of age) are described. In both the cases subglottic impaction occurred consequent to attempted removal of foreign body by blind finger sweeping. The clinical presentation, investigations, and management of these rare cases are discussed.  (+info)

Correlating fibreoptic nasotracheal endoscopy performance and psychomotor aptitude. (2/460)

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)

Perianesthetic dental injuries: frequency, outcomes, and risk factors. (3/460)

BACKGROUND: Dental injury is well-recognized as a potential complication of laryngoscopy and tracheal intubation. However, the frequency, outcomes, and risk factors for this problem have not been documented in a well-defined patient population. METHODS: The authors analyzed the dental injuries of 598,904 consecutive cases performed on patients who required anesthetic services from 1987 through 1997. Dental injuries were defined as perianesthetic events (those occurring within 7 days) that required dental interventions to repair, stabilize, or extract involved dentition or support structures. A 1:3 case-control study of 16 patient and procedural characteristics was performed for cases that occurred during the first 5 yr of the study. Conditional logistic regression was used for data analysis. RESULTS: There were 132 cases (1:4,537 patients) of dental injury. One half of these injuries occurred during laryngoscopy and tracheal intubation. The upper incisors were the most commonly involved teeth, and most injuries were crown fractures and partial dislocations and dislodgements. Multivariate risk factors for dental injury in the case control study included general anesthesia with tracheal intubation (odds ratio [OR] = 89), preexisting poor dentition (OR = 50), and increased difficulty of laryngoscopy and intubation (OR = 11). CONCLUSIONS: Based on these data from a large surgical population at a single training institution, approximately 1:4,500 patients who receive anesthesia services sustain a dental injury that requires repair or extraction. Patients most at risk for perianesthetic dental injury include those with preexisting poor dentition who have one or more risk factors for difficult laryngoscopy and tracheal intubation.  (+info)

Bolus dose remifentanil for control of haemodynamic response to tracheal intubation during rapid sequence induction of anaesthesia. (4/460)

The effect of three bolus doses of remifentanil on the pressor response to laryngoscopy and tracheal intubation during rapid sequence induction of anaesthesia was assessed in a randomized, double-blind, placebo-controlled study in four groups of 20 patients each. After preoxygenation, anaesthesia was induced with thiopental 5-7 mg kg-1 followed immediately by saline (placebo) or remifentanil 0.5, 1.0 or 1.25 micrograms kg-1 given as a bolus over 30 s. Cricoid pressure was applied just after loss of consciousness. Succinylcholine 1 mg kg-1 was given for neuromuscular block. Laryngoscopy and tracheal intubation were performed 1 min later. Arterial pressure and heart rate were recorded at intervals until 5 min after intubation. Remifentanil 0.5 microgram kg-1 was ineffective in controlling the increase in heart rate and arterial pressure after intubation but the 1.0 and 1.25 micrograms kg-1 doses were effective in controlling the response. The use of the 1.25 micrograms kg-1 dose was however, associated with a decrease in systolic arterial pressure to less than 90 mm Hg in seven of 20 patients.  (+info)

Laryngeal movements during the respiratory cycle measured with an endoscopic imaging technique in the conscious horse at rest. (5/460)

A video-laryngoscopic method, implemented with an algorithm for the correction of the deformation inherent in the endoscope optical system, has been used to measure the dorsoventral diameter (Drg) and the cross-sectional area (CSArg) of the rima glottidis in five healthy workhorses during conscious breathing at rest. Simultaneous recording of the respiratory airflow was also obtained in two horses. Drg measured 82.7 +/- 4.5 mm (mean +/- S.D.) independently of the respiratory phase, and did not differ from the measurement in post-mortem anatomical specimens of the same horses. CSArg ranged from 1130 +/- 117 mm2 (mean +/- S.D.) during the inspiratory phase to 640 +/- 242 mm2 during the expiratory phase; being always narrower than tracheal cross-sectional area, which was 1616 +/- 224 mm2, as determined from anatomical specimens. Both inspiratory and expiratory airflow waves displayed a biphasic pattern. Maximal laryngeal opening occurred in phase with the second inspiratory peak, while during expiration CSArg attained a minimum value during the first expiratory peak which was significantly smaller (P < 0.01) than the area subsequently maintained during the rest of the expiratiory phase. These quantitative measurements of equine laryngeal movements substantiate the important role played by the larynx in regulating upper airway respiratory resistance and the expiratory airflow pattern at rest.  (+info)

Intramuscular rocuronium in infants and children: a multicenter study to evaluate tracheal intubating conditions, onset, and duration of action. (6/460)

BACKGROUND: This multicenter, assessor-blinded, randomized study was done to confirm and extend a pilot study showing that intramuscular rocuronium can provide adequate tracheal intubating conditions in infants (2.5 min) and children (3 min) during halothane anesthesia. METHODS: Thirty-eight infants (age range, 3-12 months) and 38 children (age range, 1 to 5 yr) classified as American Society of Anesthesiologists physical status 1 and 2 were evaluated at four investigational sites. Anesthesia was maintained with halothane and oxygen (1% end-tidal concentration if <2.5 yr; 0.80% end-tidal concentration if >2.5 yr) for 5 min. One half of the patients received 0.45 mg/kg intravenous rocuronium. The others received 1 mg/kg (infants) or 1.8 mg/kg (children) of intramuscular rocuronium into the deltoid muscle. Intubating conditions and mechanomyographic responses to ulnar nerve stimulation were assessed. RESULTS: The conditions for tracheal intubation at 2.5 and 3 min in infants and children, respectively, were inadequate in a high percentage of patients in the intramuscular group. Nine of 16 infants and 10 of 17 children had adequate or better intubating conditions at 3.5 and 4 min, respectively, after intramuscular rocuronium. Better-than-adequate intubating conditions were achieved in 14 of 15 infants and 16 of 17 children given intravenous rocuronium. Intramuscular rocuronium provided > or =98% blockade in 7.4+/-3.4 min (in infants) and 8+/-6.3 min (in children). Twenty-five percent recovery occurred in 79+/-26 min (in infants) and in 86+/-22 min (in children). CONCLUSIONS: Intramuscular rocuronium, in the doses and conditions tested, does not consistently provide satisfactory tracheal intubating conditions in infants and children and is not an adequate alternative to intramuscular succinylcholine when rapid intubation is necessary.  (+info)

Clinical assessment of a plastic optical fiber stylet for human tracheal intubation. (7/460)

BACKGROUND: The authors compared the performance of a prototype intubation aid that incorporated plastic illumination and image guides into a stylet with fiberoptic bronchoscopy and direct laryngoscopy for tracheal intubation by novice users. METHODS: In a randomized, nonblinded design, patients were assigned to direct laryngoscopy, fiberoptic bronchoscopy, or imaging stylet intubation groups. The quality of laryngeal view and ease with which it was attained for each intubation was graded by the laryngoscopist. Time to intubation was measured in 1-min increments. A sore-throat severity grade was obtained after operation. RESULTS: There were no differences in demographic, physical examination, or surgical course characteristics among the groups. The laryngoscope produced an adequate laryngeal view more easily than did the imaging stylet or bronchoscope (P = 0.001) but caused the highest incidence of postoperative sore throat (P<0.05). Although the time to intubation for direct laryngoscopy was shorter than for imaging stylet, which was shorter than fiberoptic bronchoscopy (P<0.05), the quality of laryngeal view with the imaging stylet was inferior to both direct laryngoscopy and fiberoptic bronchoscopy techniques (P<0.05). CONCLUSIONS: Novices using the imaging stylet produce fewer cases of sore throat (compared with direct laryngoscopy) and can intubate faster than when using a bronchoscope in anesthetized adult patients. The imaging stylet may be a useful aid for tracheal intubation, especially for those unable to maintain skills with a bronchoscope.  (+info)

Laryngeal mask airway size selection in males and females: ease of insertion, oropharyngeal leak pressure, pharyngeal mucosal pressures and anatomical position. (8/460)

We have compared ease of insertion, oropharyngeal leak pressure, directly measured pharyngeal mucosal pressure and anatomical position (assessed fibreoptically) for the size 4 and size 5 laryngeal mask airway (LMA) in 20 male and 20 female patients. Microchip pressure sensors were attached to the LMA at locations corresponding to the piriform fossa, hypopharynx, base of the tongue, lateral and posterior pharynx, and the oropharynx. Oropharyngeal leak pressure, mucosal pressure and fibreoptic position were recorded during inflation of the cuff from 0 to 30 ml in 10-ml increments. In males, oropharyngeal leak pressure over the inflation range was higher for size 5 (21 vs 17 cm H2O; P = 0.01); mucosal pressure over the inflation range was higher in the posterior pharynx for size 4 (7 vs 2 cm H2O; P = 0.007), and higher in the piriform fossa (8 vs 5 cm H2O; P = 0.003) and hypopharynx (9 vs 5 cm H2O; P = 0.003) for size 5. In females, oropharyngeal leak pressure over the inflation range was the same (21 vs 21 cm H2O), but mucosal pressure over the inflation range was higher in the piriform fossa (21 vs 8 cm H2O; P = 0.003) and posterior pharynx (4 vs 2 cm H2O; P = 0.004) for size 4, and higher in the lateral pharynx (5 vs 1 cm H2O; P = 0.01) and oropharynx (11 vs 5 cm H2O; P = 0.009) for size 5. The distribution of mucosal pressure was different for size 4 between males and females, but not for size 5. For both males and females, fibreoptic position was similar. We conclude that the size 5 LMA is optimal in males, but either size is suitable for females. The shape of the pharynx may be different between males and females.  (+info)

MICROLARYNGOSCOPY. What is a Microlaryngoscopy?. Laryngoscopy is a procedure that allows your physician to look at your larynx (voice box) using a laryngoscope. Micro refers to getting a very close (magnified) view of the area to see every tiny detail. This can be done with a special telescope or operating microscope.. What are the indications for Microlaryngoscopy?. Microlaryngoscopy is especially useful for conditions in which evaluation or treatment of the vocal cords or immediate surrounding airway needs to be performed. Problems involving the VOCAL CORDS result in varying degrees of HOARSENESS, breathing or speech abnormalities, and laryngoscopy is commonly used to evaluate these symptoms. Microlaryngoscopy gives the surgeon the ability to view the larynx in detail. This is vitally important because minute (very small) changes can produce large changes in a persons voice.. What is involved with Microlaryngoscopy?. Microlaryngoscopy does not usually require an overnight stay in the ...
Four different maneuvers-simple direct laryngoscopy without any assistance (control), simple direct laryngoscopy with mandibular advancement, simple direct laryngoscopy with the BURP maneuver, and simple direct laryngoscopy with the combination of mandibular advancement and the BURP maneuver-were performed in each subject (fig. 1). First, simple direct laryngoscopy was attempted with maximum efforts to visualize the larynx; visibility of the larynx was evaluated by means of the Cormack-Lehane classification system. We defined the Cormack-Lehane grade as follows: I = most of the glottis is visible; II = the posterior commissure is visible; III = no part of the glottis can be seen except the epiglottis; IV = not even the epiglottis can be seen. 7 If the visualization of the glottis was categorized as Cormack-Lehane grade I, the pillow was removed and direct laryngoscopy was reattempted. If the visualization of the larynx was still categorized as Cormack-Lehane grade I even with this treatment, the ...

Results Seven subjects comprised the experienced group, while 10 individuals were in the inexperienced group. The overall intubation success rate was comparable between both devices (53% vs 26%, P = 0.09); however, mean time to intubate with the conventional laryngoscope was faster (25.5 vs 39.4 s, P ...
To the Editor:--Teaching direct laryngoscopy to the novice may be associated with anxiety for both instructor and student. This can be attributed partly to the fact that the instructor cannot see what the laryngoscopist is (or is not) visualizing during the procedure. In an effort to solve this problem, we used a newly developed direct laryngoscopy video system, the Airway Cam (Airway Cam Technologies, New York, NY), which may be purchased from the manufacturer for approximately $6,000. The system consists of a headframe-mounted miniature camera (11-mm lens with 90 degrees prism) connected to a video monitor. The frame is placed on the head, and the camera is adjusted until it is adjacent to the laryngoscopists dominant eye (direct laryngoscopy is a monocular procedure; Figure 1). In this position, the camera allows the instructor and the student to view the entire laryngoscopy procedure, from insertion of the laryngoscope to placement of the endotracheal tube. Importantly, the instructor can ...

Indirect laryngoscopy allows practitioners to see around the corner of a patients airway during intubation. Inadequate airway management is a major contributor to patient injury, morbidity and mortality. The purpose of the present study was to evaluate the video quality of commercially available video laryngoscopy systems. A team of four investigators at the University of Nebraska at Omaha and the Peter Kiewit Institute performed intubation simulations using a number of video laryngoscopy systems. Testing was done with a Laerdal Difficult Airway Manikin (Laerdal Medical Corp., Wappingers Falls, NY) in a setting that simulated difficult airways, adverse lighting conditions and various system configurations (e.g., maximizing screen contrast, minimizing screen brightness, maximizing screen color hue, etc.). Systems included the STORZ C-MACTM (KARL STORZ Endoscopy, Tuttlingen, Germany), a prototype developed by STORZ (a McIntosh #3 video blade with USB connectivity to an ultra mobile PC; UMPC) ...
Indirect laryngoscopy and flexible laryngoscopies often are performed in the doctors office, usually using local anesthetic. They usually take only 5 to 10 minutes.. Indirect laryngoscopy will require your child to sit up straight in a high-backed chair with a headrest and open his or her mouth wide. The doctor will spray the throat with an anesthetic or numbing medication (which your child will gargle and spit out), then cover the tongue with gauze and hold it down.. The doctor will hold up a warm mirror to the back of the throat and, with a light attached to his or her headgear, will tilt the mirror to view various areas of the throat. Your child may be asked to make high-pitched or low-pitched sounds so that the doctor can view the larynx and see the vocal cords move. Flexible laryngoscopy uses a flexible laryngoscope (a thin, flexible instrument that lights and magnifies images) for a better view of the larynx and vocal cords.. This might be done in an operating room under general ...
Laryngoscopy is examination of the throat using a small flexible camera, or endoscope. Laryngoscopy provides a view of the throat while a patient is performing normal actions such as breathing, speaking, coughing and swallowing.. Laryngoscopy may be performed through the nose or through the mouth.. Laryngoscopy through the nose uses a small thin endoscope. This is carefully passed through the nose, and then down behind the palate to examine the throat and larynx.. This may also be called flexible fiberoptic laryngoscopy or distal chip endoscopy - both of these procedures are the same in terms of what a patient feels. The difference is the technology in the camera or endoscope used for the examination.. Laryngoscopy through the mouth may use a rigid angled telescope. A patient is seated in a sniffing position with the chin and face forward as if smelling a flower. The examiner holds the patients tongue and the endoscope is placed through the mouth. Images are recorded and portrayed on a ...
Predicting difficult airway continues to be problematic for even the most seasoned of anesthesiologists. In our study, the resident class will be our sample population. The residents will be randomly assigned into two groups: the experimental group will be utilizing the new preoperative airway assessment form and the control group will be utilizing the standard anesthesia record. Simultaneously, a subset of our anesthesia experts will also be assessing patients preoperatively. The five areas of difficult airway management will be considered: difficult mask ventilation, difficult supraglottic airway, difficult laryngoscopy, difficult intubation, and difficult surgical airway.. According to the American Society of Anesthesiologists, the incidence of intubation has remained stable throughout the 1980s and 1990s despite attempts to predict its occurrence. Many of these cases were considered to be preventable; therefore, a better prediction of and preparation for difficult airway management may lead ...
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.. ...

Tracheal intubation is one of the most common medical procedures performed in hospitals. On one hand, it is highly successful and easy to perform using a rigid laryngoscope. On the other hand, hypoxic brain damage and death may result rapidly if it is unsuccessful.
Authors: Aziz MF et al., Anesth Analg 2015 Nov 17;. In patients with predicted difficult airways intubated in the operating room, the GlideScope had a higher first-attempt intubation success rate than the C-MAC D-Blade.. Video laryngoscopy (VL) improves intubation success in patients with predicted difficult airways primarily by ensuring glottic visualization. While VL with acute-angled devices has been compared to direct laryngoscopy, there is little information about the clinical equipoise between different hypercurved blades in this setting.. In a noninferiority trial, investigators in three academic hospitals randomized 1100 adult patients undergoing general anesthesia who had markers of intubation difficulty (Mallampati class III or IV, reduced mouth opening, or large neck circumference) to VL with either a GlideScope or C-MAC D-blade. The study was funded by the maker of the C-MAC. Patients with unstable cervical spine fractures or history of previous failed airways were excluded. ...

Bulatovic R, Taneja R. In Response to Videolaryngoscopy as a new standard of care. Zaouter C, Calderon J, Hemmerling TM. Br J Anaesth. 2015. 114(2):181-183.. Dear sir,. We read with interest Dr. Zauters editorial on the evolving role of videolaryngoscopy in anesthestic care (1). Overall we do agree with the authors that videolaryngoscopes will and should be available freely in the foreseeable future. As anesthetists working in a teaching hospital, we already note that residents often choose these as their first-choice for laryngoscopy in anticipated difficult intubations.. However, with increasing availability of new technology such as this, we must acknowledge that trainees will progressively lose their skills with conventional laryngoscopy. This may have safety implications for patients needing anaesthesia in remote locations where videolaryngoscopy may not be the norm. Hence, our younger colleagues having to provide anaesthetic services in such settings may find themselves underprepared or ...

RESULTS: Propofol requirements were 26.6% lesser in Group D (P,0.000 HS). There was a initial rise of HR during intubation ...
In anesthesia, the Mallampati score or Mallampati classification, named after the Indian-born American anaesthesiologist Seshagiri Mallampati, is used to predict the ease of endotracheal intubation. The test comprises a visual assessment of the distance from the tongue base to the roof of the mouth, and therefore the amount of space in which there is to work. It is an indirect way of assessing how difficult an intubation will be; this is more definitively scored using the Cormack-Lehane classification system, which describes what is actually seen using direct laryngoscopy during the intubation process itself. A high Mallampati score (class 3 or 4) is associated with more difficult intubation as well as a higher incidence of sleep apnea. The score is assessed by asking the patient, in a sitting posture, to open his or her mouth and to protrude the tongue as much as possible. The anatomy of the oral cavity is visualized; specifically, the assessor notes whether the base of the uvula, faucial ...

BACKGROUND: With improvements in endoscopic and interventional radiologic therapies, insertion of gastroesophageal balloon tamponade catheters, commonly known as Sengstaken-Blakemore or Minnesota tubes, is a rarely performed procedure for esophageal or gastric variceal bleeding. In small hospitals or freestanding emergency departments, endoscopic or interventional radiology (IR) therapies might not be available, so patients with exsanguinating variceal bleeding must be stabilized or temporized for transport to larger hospitals. Occasionally, tamponade devices are necessary as a rescue therapy for failed endoscopic or IR therapies or can be used as definitive therapy in select cases. In addition to being rarely performed, there are multiple technical complications associated with blind insertion of tamponade catheters. DISCUSSION: We describe a novel use of indirect laryngoscopy using a Glidescope for assisting in placement of a Minnesota tube in 4 patients with exsanguinating esophageal bleeding.

In preparation for intubation, many attendings, upon seeing my eager, young face, steer the Glidescope in my direction. I discovered a little bit of confidence is a dangerous thing when the airway is involved; thus, I love having this tool powered up and ready. Its perfect for airways during chest compressions/resuscitation and many difficult airways. Like the faithful bougie, I like to have a fiberoptic device at the bedside during an ETI. However, it seems that many physicians think one should learn to intubate solely with video laryngoscopy but in my limited experience, I have run into occasional problems where I converted from VL to DL with immediate success. Of note, however, I wasnt taught any specific set of skills for VL. ...

Examination of the voice box can be done with a flexible scope passed through the nose. This examination can be done in the office.. If a rigid scope is used, the examination is done either in the office or in the operating room. This type of scope is passed through the mouth.. While office evaluations are good for evaluating most forms of hoarseness, a rigid examination allows a better, more magnified view of most vocal cord abnormalities and what might be required to treat the problem. Treatment of vocal cord growths, swallowing problems, or voice box masses is best evaluated by a rigid scope examination.. Flexible voice box examination (laryngoscopy) is done in the office with topical anesthesia. The examination is usually done with the child sitting upright. The examination takes less than 5 minutes to complete. Risks for this type of procedure are minimal, with the most common risk being a nosebleed.. Rigid laryngoscopy is done in the operating room with the child asleep with a mask placed ...

Laryngoscopy is an endoscopic procedure in which a special instrument with a tiny camera is used to view the anatomy of the voice box.
Video-assisted laryngoscopy (VL) is being used increasingly in adult, paediatric and neonatal populations although its use has not been extensively studied in a neonatal setting. The authors experiences on the neonatal unit suggested that there is increased team confidence around tube or catheter placement and intubation is more successful when trainee and trainer are able to view the procedure using a video screen. This article outlines a study that looks at this theory ...
In the past two decades, airway management has been revolutionized by the development of video laryngoscopy, hyperangulated blade geometry, optical stylets, laryngeal masks, and a host of advances in airway pharmacology and technique. The core skill of airway management, however, remains laryngoscopy, whether or not the operator uses a blade with a camera at the end. In this presentation, we break down laryngoscopy into its discrete components and describe best practice technique at each step. We will start by describing common mistakes made in patient positioning; proposing a set of parameters the provider can use to guide positioning that is optimal for laryngoscopy, including the configuration of the patient in the bed, the bed height and head elevation, as well as provider stance. We then move into the effect of laryngoscope grip on operator catecholamine management and describe the optimal laryngoscope grip for emergency airway management. We next confront one of the core principles of RSI, ...
Introduction:. Mans curiosity to visualize the larynx dates back to before Garcias contribution to the field of laryngoscopy. Benjamin Guy Babington, Ludwig Turck, Johann Czermak, Morell Mackenzie, Hans Kuhn, Robert Miller, Robert Macintosh, Adolf Kussmaul have all significantly contributed to laryngoscopy.1-4 In 1890s, working with a tubed esophagoscope modified from a urethroscope, Kirstein noted that if the scope intended for the esophagus accidentally slipped into the larynx and trachea, an excellent view could be obtained. Therefore, in 1895, Kirstein began developing a reproducible method to view the larynx directly. Initially, Kirstein used a 25 cm tubed esophagoscope with the upper incisors serving as a fulcrum. This allowed Kirstein to displace the base of the tongue and epiglottis anteriorly with the tip of the scope. Kirsteins practice of direct laryngoscopy was termed Autoscopy. Historical accounts depict Kirstein performing autoscopy from in front of the patient with 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 ...

BACKGROUND Hypertension often occurs after tracheal intubation using a Macintosh laryngoscope and may lead to rare but serious complications. The Macintosh laryngoscope may increase the incidence of hypertension because it requires forced alignment of the oral and pharyngeal axes in order to view the glottis. In contrast, the McGRATH MAC video laryngoscope does not require this manipulation. The objective of this study was to evaluate the incidence of hypertension after tracheal intubation using a McGRATH laryngoscope compared with a Macintosh laryngoscope. METHODS Data of 360 consecutive patients who underwent general anesthesia with tracheal intubation by Macintosh laryngoscope or McGRATH video laryngoscope were obtained retrospectively. A total of 16 variables including patient characteristics, anesthetic drug used, and intubation techniques were extracted as potential factors affecting the incidence of hypertension after intubation. The incidence of hypertension after tracheal intubation was
Press Release issued Oct 5, 2016: Laryngoscopy is the technique of examining the anatomical structures of larynx, throat and the vocal cords with the help of the instrument known as laryngoscope. Video Laryngoscopy is a method of observing and recording movement of the vocal cords and larynx. Laryngoscopy can be performed in direct laryngoscopy and indirect laryngoscopy. Direct laryngoscopy involve placing of tube (laryngoscope) in the back of the throat which assists the doctor to examine the throat and remove the foreign body or infected tissue for biopsy. Laryngoscopy with strobe light includes the usage of strobe light which provides the doctor more clear image and information about the voice box. The process of tissue removal is generally done after the administration of anesthesia. Indirect laryngoscopy particularly includes visualization of vocal cords, upper tracheal rings and larynx.

Press Release issued Jan 20, 2017: Video laryngoscope device is used to view anatomical structure of the larynx for detailed examination. The visualization of the larynx is done with a digital laryngoscope or fiber optic inserted transorally or transnasally. The images are recorded for a more detailed examination. Larynx examination can be performed by indirect laryngoscopy and direct laryngoscopy. Direct laryngoscopy includes setting of tube (laryngoscope) in the back of the throat which helps the specialist to inspect the throat and eliminate the contaminated tissue for biopsy. The process of tissue removal (biopsy) is normally done after the administration of anesthesia. Indirect laryngoscopy predominantly includes visualization of upper tracheal rings, vocal cords, and larynx. Growing awareness among healthcare professionals about technologically advanced video laryngoscopes and its advantages over traditional laryngoscopes are helping in expanded use beyond hospital settings which are the factors

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

CONTEXT. The airway is a crucial component in the management of unconscious, anaesthetised or sedated patients.Insufficient ventilation or difficult intubation are detriments to health and difficult to predict, even in patients without anatomical pathologies or abnormalities of the upper airways.. Difficulty in airway management is defined by the presence of one of these criteria: difficult mask ventilation, difficult direct laryngoscopy, difficult tube insertion or failure of tracheal intubation.. Several quick bedside tests exist and can be used to identify high risk for difficult airways.. CLINICAL QUESTION. What is the most appropriate clinical screening test to predict difficult airway in adults without obvious airway abnormalities?. BOTTOM LINE. For difficult direct laryngoscopy, the upper lip ...
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 ...

Securing the airway by tracheal intubation with direct laryngoscopy (DL) is an established and preferred technique in emergency settings and clinical anaesthesia practice. The limitations of DL are well known. To achieve a learning curve with a 90% probability of performing a successful intubation, more than 57 attempts are required to develop enough experience with the technique.1 2 To obtain optimal visualisation of the glottis, DL requires alignment of the oropharyngeal-laryngeal axes.. However, the first-pass success rate of intubation in emergency settings ranges from 40% to 80%,3-7 in intensive care units from 55% to 68%8-10 and in the operating room from 63% to 85%.11-14 Several studies have shown a correlation between increased complications and more than two intubation attempts.15-17 Indirect video laryngoscopy has become a widely accepted method for learning the techniques of airway management because it enables an optimised view of the glottis without a direct line of sight.18-20 ...

Authors: Hoshijima H et al., Anaesthesia 2014 May 13;. A meta-analysis showed superior laryngeal view with the Pentax AWS but no other differences in performance.. To compare performance of the Pentax Airway Scope (AWS) video laryngoscope and the Macintosh direct laryngoscope, researchers performed a meta-analysis of 17 randomized, controlled trials involving 1800 adults undergoing oral or nasal tracheal intubation. Each study was classified as involving patients with either anticipated difficult or normal airways, based on patient characteristics, including morbid obesity, cervical spine immobilization, history of obstructive sleep apnea, and predicted difficult intubation (thyromental distance ,6 cm, Mallampati class 3-4); nine trials involved difficult airways.. Whereas the Pentax AWS offered a superior glottic view, there were no differences in other outcomes, including rate of successful first pass intubation, intubation time, and rate of oral or pharyngeal injury - irrespective of airway ...

BackgroundThe incidence of difficult intubation in patients undergoing general anaesthesia is estimated to be approximately 1-18% whereas that of failure to intubate is 0.05-0.35%.1,2,3 Various methods have been used for prediction of difficult laryngoscopy. Although, upper lip bite has been shown to be a promising test in its introductory article, repeated validation in various populations is required for any test to be accepted as a routine test. We have compared upper lip bite test (ULBT), modified Mallampati test (MMC) and thyromental distance (TMD) individually and in various combinations to verify which of these predictor tests are significantly associated with difficult glottic exposure.MethodsAfter obtaining institutional ethics committee approval, 402 ASA I and II adult patients undergoing elective surgical procedures requiring endotracheal intubation were included. All the three test were performed in all the patients preoperatively and their glottic exposure was recorded by ...

Objective: To determine 1) airway outcome of infants with laryngomalacia who do not undergo routine direct laryngoscopy (DL) and bronchoscopy (B), 2) the age at resolution of laryngomalacia, and, 3) outcome of supraglottoplasty as a function of the type of laryngomalacia and the presence of concomitant disease. Study Design: Retrospective chart review. Methods: The records of all infants diagnosed with laryngomalacia by flexible fiberoptic laryngoscopy (FFL) between 1990 and 1998 in the Department of Otolaryngology - Head and Neck Surgery, University of Iowa (Iowa City, IA) were reviewed. The type of laryngomalacia was designated by a new classification scheme (types 1-3) based on the site of supraglottic obstruction and the type of supraglottoplasty indicated, should the patient later require surgical intervention. The log rank test was used to compare age at resolution and outcome between types of laryngomalacia and between infants with isolated laryngomalacia versus those with additional congenital
Laryngoscopes are, simply put, devices that allow to view the larynx. The larynx can be looked at either directly or indirectly.. Devices for direct laryngoscopy essentially establish a direct line of sight between the eye of the practitioner and the larynx. Direct laryngoscopes include the typical handle and blade assemblies.. Indirect laryngoscopes on the other hand use camera or fiberoptic technology to view the larynx. These devices include, for example, videolaryngoscopes or optical stylets. Indirect laryngoscopes allow an around-the-corner look at the larynx by moving the point of view downwards along the curved laryngoscope blade closer to the vocal chords.. ...
Background Direct laryngoscopy requires movement of the head, neck, and cervical spine. Spine movement may be limited for anatomic reasons or because of cervical spine injury. The Bullard laryngoscope, a rigid fiberoptic laryngoscope, may cause less neck flexion and head extension than conventional laryngoscopes. The purpose of this study was to compare head extension (measured externally), cervical spine extension (measured radiographically), and laryngeal view obtained with the Bullard, Macintosh, and Miller laryngoscopes. Methods Anesthesia was induced in 35 ASA 1-3 elective surgery patients. Patients lay on a rigid board with head in neutral position. Laryngoscopy was performed three times, changing between the Bullard, Macintosh, and Miller laryngoscopes. Head extension was measured with an angle finder attached to goggles worn by the patient. The best laryngeal view with each laryngoscope was assessed by the laryngoscopist. In eight patients, lateral cervical spine radiographs were taken ...

TruViewEVO2 videolaryngoscope (Truphatek, Israel) is a modified version of the Truphatek 1. We used this device in four patients with difficult airways. A 77-year-old obese woman, scheduled for nasal surgery, had short neck and small jaw. After induction of anesthesia and neuromuscular blockade, laryngoscopy was attempted using a Macintosh blade, but the epiglottis, but not the glottis, was seen. A full view of the glottis was obtained when the TruView was used, and the trachea was easily intubated. In another two patients, in whom laryngoscopy with a Macintosh blade had failed, and in one patient with limited mouth opening, the TruView allowed us to see the glottis and to intubate the trachea without difficulty. Therefore, we believe that the TrueViewEVO2 videolaryngoscope is useful in patients with difficult airways.
Background: Airway Management is prime importance to the anaesthesiologist of all the anaesthetic deaths 30 % to 40 % are attributed to the inability to manage a difficult airway.

BOTHELL, Wash., April 18, 2011 /CNW/ -- GlideScope Video Laryngoscope from Verathon Medical Canada Celebrates 10th Anniversary of Video Laryngoscopy and Improving Patient Care.
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 ...

Indirect laryngoscopy provided reasonable observation, but substantial diagnostic and surgical constraints remained. With advances in anesthesia, patients better tolerated instruments placed in their hypopharynx, and this paved the way for exploitation of direct laryngoscopy.. Adelbert von Tobold is credited with the first direct visualization of the larynx in 1864 using a tongue depressor and mirror for illumination.(9) His technique was repeated by various practitioners who all sought to improve the view. Just as today, airway pioneers were beset with the problems of displacing the anatomy and adequate illumination.(10,11) To this day, almost every development in direct laryngoscopy equipment and technique has been directed at overcoming these two adversities.. Early techniques consisted of using a tongue spatula (depressor) to displace the tongue and a handheld mirror to focus light into the patients mouth. Head-mounted mirrors soon replaced the handheld mirrors, and light sources ranged ...

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 ...

Background and objectives. Hospital-acquired infections (HAIs) are largely preventable through risk analysis and modification of practice. Anaesthetic practice plays a limited role in the prevention of HAIs, although laryngoscope use and decontamination is an area of concern. We aimed to assess the level of microbial contamination of re-usable laryngoscope blades at a public hospital in South Africa. Setting. The theatre complex of a secondary-level public hospital in Johannesburg. Methods. Blades from two different theatres were sampled twice daily, using a standardised technique, over a 2-week period. Samples were quantitatively assessed for microbial contamination, and stratified by area on blade, theatre and time using Fisher's exact test. Results. A contamination rate of 57.3% (63/110) was found, with high-level contamination accounting for 22.2% of these. Common commensals were the most frequently isolated micro-organisms (79.1%), but important hospital pathogens such as Enterobacter species

This laryngoscope blade has an elongated, transected tube-shape shaft. A major part of the length of the blade is straight and a minor part of the blade is smoothly curved to form a tip which is tapered inwardly. A flange formed by the tube and a lamp are located on the left-hand side of the blade (viewed by a patient). The tube-shape is sufficient to permit an endotracheal tube to be placed in a patient through the blade during intubation.
Direct laryngoscopy using a Miller 1 blade, augmented by external laryngeal manipulation resulted in a Cormack-Lehane grade 3b view (tip of retroverted epiglottis only) and percent of glotttic opening (POGO) score seen was 0%. An Airtraq size 0 (infant) preloaded with a 3.0-mm ID microcuff endotracheal tube was inserted into the oropharynx. The Airtraq provided a full view of the entire glottic opening (Cormack-Lehane grade 1, POGO score 100%). The ett was advanced along the Airtraq guide channel through the vocal cords on first attempt ...
Indirect laryngoscopy can be performed by obtaining an image of the glottic opening in 2 ways: (1) transmission through a fiberoptic bundle or a system of prisms such as the Airtraq laryngoscope (Prodol Meditec SA, Vizcaya, Spain) to a lens viewed by the operator or a video system or (2) a video camera known as the charge-coupled device that . ...
