Composition of the extracellular matrix in human cricoarytenoid joint articular cartilage. (1/82)

The extracellular matrix of the human cricoarytenoid joint articular cartilage is involved in different pathological changes. Interestingly, in contrast to the limb joints, the extracellular matrix composition of the healthy cricoarytenoid joint articular cartilage has not yet been elucidated except by some light microscopical investigations. The present study investigates the extracellular matrix components of the cricoarytenoid joint articular cartilage by means of light microscopy, immunohistochemistry, transmission electron microscopy and scanning electron microscopy and compares them with the limb joints for a better understanding of their involvement in joint disease. Chondrocytes near the joint surface of the cricoid and arytenoid cartilage differ from chondrocytes of deeper cartilage layers. The extracellular matrix of the articular cartilage contains chondroitin-4-sulfate, chondroitin-6-sulfate and keratansulfate as well as collagen types II, III, VI, IX and XI. Type-III-collagen shows a special distribution throughout the joint cartilage. In deeper cartilage layers, type-III-collagen occurs only pericellularly; in higher cartilage layers type-III-collagen is also located territorially and interterritorialy in small amounts. Scanning and transmission electron microscopy have revealed the articular surface of the cricoid and arytenoid cartilage to consist of a network of irregularly organized collagen fibrils, which are lined by a layer of electron dense material. The network coats subjacent collagen bundles which descend obliquely downward and intermingle at right angles in the middle part of the articular cartilage with collagen bundles of the deeper cartilage zones. The articular cartilage surface shows structural characteristics which differ from the underlying cartilage. The superficial electron dense layer possibly plays a role in the lubrication of the articular cartilage surface. The alignment of the fibrillar structures in the articular cartilage of the cricoarytenoid joint varies from those of the limb joints based on the different strain occurring during arytenoid movement. Nevertheless, the human cricoarytenoid joint articular cartilage can be compared with the joints of the limbs despite its extracellular matrix composition and its involvement in joint pathology. Evidence of type III collagen in the outermost layer of the articular cartilage of the cricoarytenoid joint presents a peculiarity, which has yet not be demonstrated in the articular cartilage of limb joints.  (+info)

New insights into the pathomechanism of postintubation arytenoid subluxation. (2/82)

BACKGROUND: Impaired movement of the cricoarytenoid joint with hoarseness and immobility of the vocal ligament can occur as a consequence of endotracheal intubation. The biomechanics and pathomechanism of cricoarytenoid subluxation have not been demonstrated to date. METHODS: The present study attempts to simulate the trauma that has been associated with arytenoid cartilage subluxation in intubation trials on 37 unfixed larynges in cadavers from persons aged 25 to 89 years. Larynges were intubated or extubated according to former conceptions of arytenoid subluxation, which assume that the arytenoid tip enters the lumen of the tracheal tube, or that a deflection of the arytenoid occurs during withdrawal of the endotracheal tube with the cuff of the tube only partially deflated. Also, manual attempts were carried out to subluxate the arytenoid cartilage. Subsequently after dissecting the left and right cricoarytenoid joint from each larynx, the morphologic changes induced experimentally were analyzed using gross microscopic and histologic methods. RESULTS: Within the scope of the experiment, it proved impossible to produce any subluxation of a cricoarytenoid joint. Histologic analysis revealed injuries of synovial folds, joint-surface impressions of the articular cartilage, and fractures in the area of the subchondral bone in some joints. CONCLUSIONS: Based on the morphologic results, it was concluded that intubation trauma of the cricoarytenoid joint does not cause subluxation per se, but rather that formation of a hemarthros or fractures of the joint bodies lead to fixation of the joint surfaces in an abnormal position. Subsequent ankylosis may occur.  (+info)

Gastric pressure during emergency caesarean section under general anaesthesia. (3/82)

Gastric pressure and volume were measured in 20 pregnant women during emergency Caesarean section under general anaesthesia with neuromuscular block. Mean gastric pressure was 11 (range 4-19) mm Hg and we can predict that 99% of women undergoing emergency Caesarean section with neuromuscular block are likely to have gastric pressures of less than 25 mm Hg (mean + 3 SD). This has implications for the amount of cricoid pressure required during induction of anaesthesia. Gastric pressure increased during delivery to 19 mm Hg and fundal pressure caused a gastric pressure of 65 mm Hg in one woman. Gastric pressure decreased significantly after delivery (P < 0.001) to 8 mm Hg. Although we measured large gastric volumes (mean 112 (range 20-350) ml), there was no correlation between gastric volume and gastric pressure.  (+info)

Osteoarthritis in cricoarytenoid joint. (4/82)

OBJECTIVE: Occurrence of osteoarthritis is a frequent event of limb joints in people over 40 years of age. The human cricoarytenoid joint is comparable with the joints of the limbs despite its structure and extracellular matrix composition. To date, little is known about the occurrence of osteoarthritis in the human cricoarytenoid joint. METHODS: Sixty-eight cricoarytenoid joints (42 male and 26 female, age 25-98 years) were analysed by means of histology, lectin histochemistry, immunohistochemistry as well as scanning and transmission electron microscopy. RESULTS: About 50% of the investigated cricoarytenoid joints aged over 40 years show degenerative changes in their joint surface structure at varying levels of intensity. The articular cartilage surface is fibrillated in some places and sometimes shows fissures. A demascing of collagen fibrils next to the joint surface and a loss of proteoglycans in the upper cartilage layers can be observed. Chondrocytes near the joint surface appear as voluminous chondrocyte clusters. The clusters and the superficial cartilage layer show a positive reaction to type VI collagen antibodies. The distribution patterns of lectins are completely changed in fibrillated cartilage areas. CONCLUSION: Degenerative alterations in diarthrodial joints resembling osteoarthritis can occur in the joints of the larynx. These structural changes of the articular cartilage are comparable to osteoarthritis of the limb joints. Osteoarthritis in the cricoarytenoid joint may lead to impaired movements of the arytenoid cartilages. Functionally the structural changes may lead to negative consequences during vocal production, such as impaired vocal quality and reduced vocal intensity.  (+info)

Effect of cricoid pressure on insertion of and ventilation through the cuffed oropharyngeal airway. (5/82)

We have assessed the effect of cricoid pressure on insertion of and ventilation through the cuffed oropharyngeal airway (COPA) in 53 patients, in a double-blind, randomized study. Two anaesthetists assessed adequacy of ventilation in anaesthetized and paralysed patients at the same time but using different methods. The first assessed ventilation clinically, by observing synchronized chest expansion with gentle manual ventilation and the second noted measurements of tidal volume (VT) and peak inspiratory pressure (PIP). Five mask ventilated breaths ('baseline') were assessed as above. Patients were then allocated randomly to receive cricoid pressure (group A, n = 28) or no cricoid pressure (group B, n = 25). Five further mask ventilated breaths ('after manoeuvre') were again assessed. A COPA was then inserted and five further breaths ('after COPA') were assessed. A COPA was inserted at the first attempt in all patients except for one in group A who required two attempts. COPA placement was difficult in one patient in group B who had a small distance between the incisor teeth. Ventilation was clinically 'adequate' in all patients except for one in the cricoid pressure group. There were no significant differences in measured VT or PIP between 'baseline' and 'after manoeuvre' breaths. Significant differences in VT and PIP were found after COPA insertion in the group that received cricoid pressure, with a mean decrease in VT of 108 ml (P = 0.0049) and a mean increase in PIP of 5.2 cm H2O (P = 0.0111).  (+info)

Competence of the internal jugular vein valve is damaged by cannulation and catheterization of the internal jugular vein. (6/82)

BACKGROUND: Experimental results suggest that the competence of the internal jugular vein (IJV) valve may be damaged when the IJV is cannulated for insertion of a central venous catheter. It has further been hypothesized that the risk of causing incompetence of the proximally located valve might be reduced by using a more distal site for venous cannulation. The present study evaluated these hypotheses in surgical patients. METHODS: Ninety-one patients without preexisting incompetence of the IJV valve were randomly assigned to undergo distal or proximal IJV cannulation (> or = 1 cm above or below the cricoid level, respectively). Color Doppler ultrasound was used to study whether new valvular incompetence was present during Valsalva maneuvers after insertion of a central venous catheter, immediately after removal of the catheter, and, in a subset of patients, several months after catheter removal, when compared with baseline findings before cannulation of the IJV. RESULTS: Incompetence of the IJV valve was frequently induced both by proximal and distal cannulation and catheterization of the IJV. Its incidence was higher after proximal than after distal cannulation (76% vs. 41%; P < 0.01) and tended to be so after removal of the catheter (47% vs. 28%; P = 0.07). Valvular incompetence persisting immediately after removal of the catheter did not recover within 8-27 months in most cases. CONCLUSIONS: Cannulation and catheterization of the IJV may cause persistent incompetence of the IJV valve. Choosing a more distal site for venous cannulation may slightly lower the risk of causing valvular incompetence but does not reliably avoid it.  (+info)

Cricoid pressure applied after placement of laryngeal mask impedes subsequent fibreoptic tracheal intubation through mask. (8/82)

We studied 70 patients to see if cricoid pressure applied after insertion of the laryngeal mask altered the success rate of tracheal intubation through the mask. After induction of anaesthesia and neuromuscular blockade, patients were randomly allocated to have either cricoid pressure (Group C) or sham pressure (Group S). The view of the glottis through the laryngeal mask was assessed before and after the test pressure, and tracheal intubation through the mask was attempted using a fibreoptic bronchoscope. The test pressure did not alter the view of the glottis in any patient in group S, whereas it narrowed the glottic aperture in 16 out of 35 patients in group C. The fibrescope was inserted into the trachea in all patients in group S and in 25 patients in group C. The success rate of tracheal intubation in group S (31 patients) was significantly higher than in group C (21 patients, P << 0.001; 95% CI for difference: 9-48%). The time for insertion of the fibrescope in group S (median (95% CI): 12 (11-12) s) was significantly faster than in group C (16 (14-17) s, P << 0.001; 95% CI for difference: 3-6 s), and the time for tracheal intubation in group S (16 (15-18) s) was significantly faster than in group C (22 (19-24) s, P < 0.0005; 95% CI for difference: 3-7 s). Cricoid pressure after insertion of the laryngeal mask makes tracheal intubation through the mask significantly more difficult.  (+info)

Definition of posterior cricoid pressure in the Legal Dictionary - by Free online English dictionary and encyclopedia. What is posterior cricoid pressure? Meaning of posterior cricoid pressure as a legal term. What does posterior cricoid pressure mean in law?
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.
Calvin A. Brown, III, MD. In a randomized trial, cricoid pressure impeded tube passage through the glottis and prolonged intubation time.. Cricoid pressure has been associated with worsened glottic views and difficult tube placement during conventional laryngoscopy and intubation. It has not been previously studied in combination with the Pentax Airway Scope (AWS), a video laryngoscope with an integrated screen and tracheal tube channel.. In a single-center operating room trial, 60 patients aged 20 to 85 years were randomized to intubation with the Pentax AWS with either cricoid pressure or "sham" pressure. Sham pressure was accomplished by placing fingers on the cricoid ring but not applying downward force. Cricoid pressure was provided by an anesthesiologist who was trained to apply 30N of downward force using a cricoid simulator. Patients with anticipated difficult airways and those needing emergent intubation were excluded. Patients were induced with standard doses of propofol and ...
Cricoid pressure, also known by the eponymous name of the Sellick manoeuvre (in American English, Sellick maneuver), is a technique used in endotracheal intubation to reduce the risk of regurgitation. The technique involves the application of pressure to the cricoid cartilage at the neck, thus occluding the esophagus which passes directly behind it. Cricoid pressure should not be confused with the "BURP" (Backwards Upwards Rightwards Pressure) manoeuvre, which is used to improve the view of the glottis during laryngoscopy and tracheal intubation, rather than to prevent regurgitation. As the name implies, the BURP manoeuvre requires a clinician to apply pressure on the thyroid cartilage posteriorly, then cephalad (upwards) and, finally, laterally towards the patients right. In 1961 Brian Arthur Sellick (1918-1996), an anaesthetist, published the paper Cricoid pressure to control regurgitation of stomach contents during induction of anesthesia-preliminary communication, describing the application ...

The lower ring - like cartilage is cricoid which is broad dorsally and narrow ventrally. The arytenoids are present at the anterior end of dorsal side of cricoid. There is also a pair of small nodules called the cartilages of santorini present at the apex of arytenoid. Trachea The larynx opens into trachea or wind pipe that runs along the length of neck, ventral to the oesophagus. The trachea enters into the thoracic cavity and divided into two branches called Bronchi. The trachea and bronchi are supported by incomplete cartilaginous rings called tracheal rings. Each bronchus enters into the lung of its side. The bronchus is further divided into small branches called bronchioles within the lung. Each bronchiole divides ...
MODEL RELEASED. Child with naso-gastric tube using sign language. Young girl aged 2 1/2 years with a permanent tracheostomy vent and a naso-gastric feeding tube, giving the sign for the letter a. The child has a congenital subglottic stenosis (SGS) grade 3, a narrowing of the subglottic airway where it passes through the ring-shaped cricoid cartilage. Grade 3 indicates the blockage is between 50% and 99%. A tracheostomy tube has been inserted below the cricoid to allow normal breathing. However this is below the larynx so the child is unable to talk normally and uses sign language to communicate. The child is unable to swallow so must be fed by tube. Treatment of SGS is normally by surgery, either by splitting the cricoid and grafting inserts of cartilage or by resection of the trachea. Congenital SGS is realtively rare, but is the third most common congenital airway problem. - Stock Image C003/8855

Cartilage is a resilient and smooth elastic tissue, rubber-like padding that covers and protects the ends of long bones at the joints, and is a structural component of the rib cage, the ear, the nose, the bronchial tubes, the intervertebral discs, and many other body components. It is not as hard and rigid as bone, but it is much stiffer and much less flexible than muscle. Because of its rigidity, cartilage often serves the purpose of holding tubes open in the body. Examples include the rings of the trachea, such as the cricoid cartilage and carina. Cartilage is composed of specialized cells called chondrocytes that produce a large amount of collagenous extracellular matrix, abundant ground substance that is rich in proteoglycan and elastin fibers. Cartilage is classified in three types, elastic cartilage, hyaline cartilage and fibrocartilage, which differ in relative amounts of collagen and proteoglycan. Cartilage does not contain blood vessels (it is avascular) or nerves (it is aneural). ...
However, Eckenhoffs article was in turn based on descriptions made half a century before by Bayeux, who reported the findings from anatomic dissections in 15 bodies of children between 4 months and 14 years of age, together with their corresponding plaster models. In that article, Eckenhoff describes the cricoid cartilage as a rigid structure that cannot be distended in order to pass the ETT, and describes how its parts come together to form a ring around the larynx. Eckenhoff actually clearly states the danger of extrapolating such cadaver findings to live human beings. Unfortunately a number of anesthesiology textbooks picked up on these anatomical descriptions of the pediatric airway since then ...
The thyroid gland is located between the C5 and T1 vertebrae. However, since the position of the thyroid gland can vary slightly among people, changes position during swallowing and can be enlarged (goiter), it is difficult to use the vertebral column as the sole landmark.. Thyroid pain is any superficial discomfort, tenderness or pain in the neck, below the thyroid cartilage (Adams apple) around the level of the cricoid cartilage that is usually exacerbated during swallowing or palpation. This tenderness or pain can extend all the way to the superior mediastinum. However the pain may not be so localized and could radiate to laterally (sternocleidomastoid muscles), superiorly (mouth, chin, jaw) or inferiorly (beyond the superior mediastinum to the chest).. ...
BACKGROUND: Resuscitation guidelines caution against extreme extension or flexion of an infants head because tracheal obstruction may occur. No data support this recommendation. The authors therefore examined the dimensions of the tracheal lumen in neutral, extended, and flexed head positions in infants undergoing general endotracheal anesthesia for elective surgery. METHODS: Eighteen healthy full-term infants were studied. A flexible fiberoptic bronchoscope was passed through a previously inserted endotracheal tube and positioned above the cricoid cartilage. Video recordings were taken in each of three head positions. Recordings were analyzed by an investigator blinded to head position. A computer-digitized technique was used to measure anterior-posterior and lateral dimensions and cross-sectional area. Data were analyzed using paired t tests and sign tests. RESULTS: No significant differences in mean tracheal dimensions with changes in head position were found. No infant had complete tracheal ...

Anesthesiology published on 6 2016. Authors: Frédéric Heymans, M.D. et al. Background: When conventional approaches to obtain effective ventilation and return of effective spontaneous breathing fail, surgical airway is the last rescue option. Most physicians have a limited lifetime experience with cricothyrotomy, and it is unclear what method should be taught for this lifesaving procedure. The aim of this study is to compare the performance of medical personnel, naive to surgical airway techniques, in establishing an emergency surgical airway in cadavers using three commonly used cricothyrotomy techniques.. Methods: Twenty medical students, without previous knowledge of surgical airway techniques, were randomly selected from their class. After training, they performed cricothyrotomy by three techniques (surgical, Merkel, and QuickTrach II) in a random order on 60 cadavers with comparable biometrics. The time to complete the procedure, rate of success, and number of complications were recorded. ...
The thyroid (Greek thyreos, shield, plus eidos, form) consists of two lobes connected by an isthmus. It is located anterior to the trachea between the cricoid cartilage and the suprasternal notch. The normal thyroid is 12-20 g in size, highly vascular, and soft in consistency. Four parathyroid glands, which produce parathyroid hormone (Chap. 424), are located posterior to each pole of the thyroid. The recurrent laryngeal nerves traverse the lateral borders of the thyroid gland and must be identified during thyroid surgery to avoid injury and vocal cord paralysis. ...

The larynx consists of a cartilaginous framework comprising the single thyroid, cricoid, and epiglottic cartilages and the paired arytenoid, corniculate, and cuneiform cartilages. The larynx is suspended from the hyoid bone by the thyrohyoid membrane. The vocal folds run from the angle formed by the thyroid lamina anteriorly to the vocal process of the arytenoid cartilages posteriorly. Alteration in the position and length of the vocal folds is primarily the result of movement of the synovial cricoarytenoid joints, with a contribution from movement of the cricothyroid joints. Above the vocal folds run the false cords, formed by the medial border of the aryepiglottic folds. These are separated from the vocal folds by horizontal sinus known as the laryngeal ventricle, which contains numerous mucin-secreting glands. ...
Our human cadaveric airway course offers delegates a unique opportunity to repetitively perform and compare different techniques of airway management on a variety of cadaveric specimens. The focus of the course will be on visualising the larynx, and appreciating the differing appearance of human airway anatomy in the cadaveric specimens. There will be plenty of hands-on practice of the skills of conventional laryngoscopy, videolaryngoscopy using a variety of different devices, LMA and i-gel insertion, oral and nasal fibreoptic intubation and cricothyroidotomy. One of the pair of delegates will have the opportunity of performing the surgical cricothyroidotomy (Cutting the Neck Option).. Cadavers offer a unique opportunity for airway practitioners to interact with and visualise human airway structures without the ethical issues or risks associated with practising on live patients. Airway management and intubation on live patients cannot be done repetitively just to compare, test, or practice ...

The rationale for RSI is a perceived reduction in the risk of pulmonary aspiration in patients considered "at risk," however the evidence behind this has recently (and appropriately) been questioned [Neilipovitz DT. Can J Anaesth 54: 748, 2007].. A traditional RSI includes fentanyl (1-2 ucg/kg, although remifentanil or alfentanil may be more reliable in terms of blunting response to DL [Jhaveri et. al. Anesthesiology 87: 253, 1997]) » Preoxygenation for 1-3 mins » defasiculating (panc 1-2 mg IV) » IV induction agent not followed by mask ventilation » SCh (1-2 mg/kg) » cricoid pressure » DL/ETT 45-90 seconds after SCh » OG/NG tube. The major concern regarding RSI is the potential for loss of airway (because paralysis is induced prior to establishment of ventilation, and given this risk it must be justified based on a dual assessment of the airway and aspiration risk (for a thorough discourse on the risk of pulmonary aspiration, see [Warner MA et al. Anesthesiology. 78: 56, 1993]). ...
The time intervals from start to location of the cricothyroid membrane were not significantly different between volunteers using the Seldinger versus the standard surgical technique. Times to tracheal puncture, as well as times to first ventilation, were significantly longer when participants were using the standard surgical cricothyroidotomy technique. Seven attempts at trachea placement had to be aborted in those using the Seldinger technique due to kinking of the guidewire, whereas six attempts had to be aborted in the group using standard surgical placement technique. Subsequent anatomic dissection revealed that the airway was accurately placed into the trachea through the cricothyroid membrane in 88.2% of the Seldinger technique attempts and in 84.0% of the standard surgical attempts. Six punctures of the thyroid vessels were observed in the cadavers receiving the standard surgical technique. Although the study in cadavers does not reflect real clinical situations, the shorter time to first ...

The objective of our work is to demonstrate in a large cohort of patients with cricotracheal stenosis that resection of long airway segments could be performed with no increased risk of postoperative complications. A consecutive series of patients getting cervical segmental cricotracheal resection (CTR) were reviewed. The typical segmental tracheal resection technique has been modified to accommodate long segment removal. Modifications include using trachea to enable the reconstruction of the larynx itself as well as the placement of a "laryngosternopexy" stitch between the thyroid lamina and the sternoclavicular ligament designed to take all of the tension off the anastomosis and to prevent inadvertent head extension ...
I struggle to ventilate the patient in the resus room, airway pressures are high, the bag doesnt empty properly. In my mind I plan ahead for the next step. Through my mind goes the thought - is this the one, the one that I cannot ventilate? Statistically it is not likely to be, but I am prepared to add two-person technique, airway adjuncts like nasopharyngeal or oropharyngeal, or supraglottic devices that I use frequently in theatre. I feel confident in the use of these methods, and (in the worst case) in cricothyroidotomy. I have practiced that numerous times on our live-tissue course on anaesthetised pigs. However - before I start any of these actions.. I routinely, almost as a reflex from theatre turn the patients head 45 degrees to the left, and then the bag suddenly empties easily - and I can ventilate the patient.. Some people think that time with TIVA in theatre has little value for emergency medicine and advanced prehospital care. I strongly disagree. This is some of the most relevant ...
The laryngeal cartilages are hyaline cartilages, with the exception of the epiglottis and vocal process of the arytenoid, which are fibroelastic cartilages.5,6 Hyaline cartilages undergo changes with time, with progressive enchondral ossification.7,8 Histopathologic studies demonstrated that the stage of the calcification and ossification is widely affected by age.9 The order of ossification is affected by the distribution of the mechanical forces applied to the laryngeal cartilages.8 Ossification begins first in the superior border of the lamina in the cricoid cartilage followed by the apex, body, and muscular process of the arytenoid cartilage, with the exception of the vocal process.10,11 Our aim was not to elucidate the pattern in which arytenoid ossification progresses, but we agree with the previously published observation that ossification initially occurs in the lateral one-third of the arytenoids peripherally and progresses to involve the center afterward.10,11 This is in concordance ...
Evidence-based recommendations on endoscopic carbon dioxide laser cricopharyngeal myotomy for relieving oropharyngeal dysphagia (swallowing difficulties)
Objectives: The aim is; laryngeal conservative surgery indications and to help conservation surgery rates to increase, by comparing preoperative vocal fold and arytenoid movements with postoperative histopathologic examinations in carcinoma of the larynx and hypopharynx. Material and method: 30 patients with laryngeal carcinomas evaluated for preoperative vocal fold and arytenoid movements were included into our study. The movements of vocal folds and arytenoids were defined clinically as mobile, fixed or limited. Postoperatively, the laryngeal specimens were divided into subglottic, glottic and supraglottic areas and fixed with formaldehit and evaluated with a pathologist. The involvement of thyroarytenoid muscle, posterior cricoarytenoid muscle, cricoarytenoid joint, paraglottic area, conus elasticus, arytenoid cartilage were investigated. Results: In cases with limited movement of vocal fold and arytenoid movements preoperatively, the rate of thyroarytenoid muscle involvement was 33.3% (2/6), ...

There are few data on the impact of simulation on the acquisition of airway management skills in general and cricothyrotomy in particular. A recent study by Boet et al.18 reported that a single simulation cricothyrotomy training session improved the procedural skills of 28 attending anesthetists and that this improvement was retained for at least a year. In the latter study, the attending anesthetists were assessed in a simulated cricothyrotomy scenario in a pretest, immediately after a debriefing and structured teaching session on cricothyrotomy insertion and at either 6 or 12 months posttest. The same scenario was used in the pretest and in the posttests; the resident played the role of an anesthesiologist called on to help with an ongoing intubation attempt. On the simulated patients arrival, the oxygen saturation was 89% and falling by 10% per minute. All intubation methods were destined to be unsuccessful, because the manikin was set up in the CICV configuration. Hence, the scenario was ...

N2 - Objectives/Hypothesis Idiopathic subglottic stenosis (ISS) is a rare type of airway stenosis of unclear etiology. Open resection, while effective, remains a complex surgery and requires a hospital stay. Endoscopic management is often preferred but has historically been associated with a high recurrence rate. We aimed to analyze our experience, consisting of a standardized endoscopic approach combined with an empiric medical treatment. Study Design Retrospective cohort study. Methods All patients with ISS managed with standardized endoscopic treatment at our institution between 1987 and 2012 were identified, and their electronic medical records were reviewed. The treatment ...
The lateral cricoarytenoid muscle is a muscle in the throat that adducts and medially rotates the arytenoid cartilage. This action adducts the vocal folds, increasing the pitch of the voice and closing the rima glottidis.

To the Editor:. We appreciate the comments by Drs. Garcia-Valladares and Espinoza1 regarding our study on granulomatosis with polyangiitis (Wegeners, GPA) persistently localized to one organ2.. As emphasized by their patients case, subglottic stenosis often evolves and can relapse as a limited process in GPA, in the absence of or with only a few other active systemic extra-respiratory tract vasculitis manifestation(s) and/or progress to fibrotic stenosis. Most of these patients with this potentially rapidly life-threatening manifestation represent a difficult therapeutic challenge3. Because the response of subglottic stenosis to conventional systemic treatments is, at best, partial and, if so, often only transient, local therapy, mainly based on repeated dilations with or without local injections of corticosteroids, represents the cornerstone of its therapeutic management4,5. The places of tracheal surgery, laser deobstruction, and local injections of other drugs, such as mitomycin, are still ...

He was started on his formula via J-tube (into the intestine) this morning. Shortly after that, the vomiting came back in full force. Blood work was done and the pancreatic levels were up. When we arrived at the hospital was 813, then later down to 650 and today it was 1023. The normal range is 32-219. So the GI doctor would like for Brayden to stay and be watched. Still no idea what is causing the pancreatitis. The pancreatitis is assumed to be some of the cause of the severe vomiting (not all the vomiting but could be a contributor). The doctor ordered something called a Farrell Valve, an enteral gastric pressure relief system, to help relive pressure on Braydens gut. It is basically an empty bag that is connected to Brayden J-tube. While he is being feed, the food goes in from his feed bag and air comes out through the Farrell bag. We have to wait and see what effect it could have. We also may be revisiting some medications that Brayden has tried in the past but this time in larger doses. ...

Congenital stridor is a symptom rather than a syndrome, so the cause of the stridor must be explored. The most common cause of inspiratory stridor in the neonatal period is laryngomalacia, which accounts for approximately three fourths of all cases. Stridor generally improves in the prone position with the head up. Laryngomalacia usually requires no therapy and disappears spontaneously around 1 year of age. Rarely, in patients with severe obstruction, supraglottoplasty may be required. Unilateral vocal cord paralysis is probably the second most common cause of stridor in the neonatal period. It is either congenital or acquired (related to cardiothoracic surgery or birth trauma). Incomplete canalization of the subglottic area and cricoid rings is the anatomical correlate in congenital subglottic stenosis, while acquired subglottic stenosis is most often caused by prolonged intubation (often related to an endotracheal tube with a diameter that is too big). Severe episodes of airway obstruction may ...
Provision of nutritional support is a crucial component of ICU care and EN is preferred over parenteral nutrition. [1] NGT insertion is simple and minimally invasive and is frequently carried out in critically ill patients. NGT-related complications are not as rare as commonly believed. Most complications are due to mechanical injury of the nose, esophagus, and stomach. Misplacement of the NGT into a pulmonary or intracranial region can also occur.[2,3] NGT syndrome was first named by Sofferman et al.[4] to describe bilateral vocal cord paralysis developed in patients with an NGT. Three pathophysiologic mechanisms were proposed as the cause of NGT syndrome; the dynamic and vertical movements of the larynx against the fixed NGT, compression of the cricoid by the NGT and the cervical spine, and tonic contraction of the cricopharyngeus muscle pulling the NGT against the postcricoid. These induce postcricoid esophageal ulceration and extended inflammation causes esophageal perforation and myositis ...
After standard monitoring(EKG, pulse oximetry, NIBP), participants were induced with remifentanil and propofol continuous infusion, using targe-controlled infusion device with prexoygenation with 100% oxygen.. Manual in-line stabilization was applied with velcro during intubation to maintain neutral head position.. After 2min from administration of rocuronium, the clinician holds the wand similar to a pencil, stands directly behind the patients head, inserts the device into the side of the mouth and sweeps the tip to the midline. After confirmation of precise location via clear light source on anterior neck, endotracheal tube was inserted and withdrawn lightwand. ...
Laryngeal Electromyography (LEMG) is a diagnostic test commonly used in patients with vocal fold movement disorder The aim of this study is to describe LEMG in patients with vocalfold immobility. A total of 55 dysphonic patients with vocal fold immobility diagnosed by laryngeal endoscopy were grouped according to probable clinical cause: 1) unknown; 2) traumatic; or 3) tumoral compression. They were submitted to LEMG by percutaneous insertion of concentric needle electrode. LEMG was conclusive in all patients and showed a majority with peripheral nerve injury. LEMG diagnosed peripheral nerve damage in 25 group 1, 12 group 2, and 11 group 3 patients. LEMG was normal in 4 patients, suggesting cricoarytenoid joint fixation. Central nervous system disorders was suggested in 2 and myopathic pattern in 1. As the major cause of vocal fold immobility is peripheral nerve damage, LEMG is an important test to confirm diagnosis ...
