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)

The ring-like cricoid cartilage is the foundation of the larynx. Both the thyroid and arytenoid cartilages form mobile synovial attachments to the strong, stable cricoid cartilage above and the cricoid is firmly anchored to the trachea below. This hyaline cartilage structure is the sole laryngeal cartilage that forms a complete ring around the upper airway. It is narrow and thick in front and forms a tall thin plate of cartilage posteriorly where it reinforces the posterior wall of the larynx. They provide attachment for numerous muscles of the larynx. Like the other laryngeal cartilages, it grows much more rapidly in the male after puberty ...
When intubating a patient under general anesthesia prior to surgery, the anesthesiologist will press on the cricoid cartilage to compress the esophagus behind it so as to prevent gastric reflux from occurring: this is known as the Sellick manoeuvre. The Sellick Manoeuvre is typically only applied during a Rapid Sequence Induction (RSI), an induction technique reserved for those at high risk of aspiration. The Sellick maneuver was considered the standard of care during rapid sequence induction for many years.[2] The American Heart Association still advocates the use of cricoid pressure during resuscitation using a BVM, and during emergent oral endotracheal intubation.[3] However, recent research increasingly suggests that cricoid pressure may not be as advantageous as once thought. The initial article by Sellick was based on a small sample size at a time when high tidal volumes, head-down positioning, and barbiturate anesthesia were the rule.[4] Cricoid pressure may frequently be applied ...
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

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 ...

Results Over 20 years, 37 725 patients were attended by the service, and 72 patients received a scalpel cricothyroidotomy. An immediate primary cricothyroidotomy was performed in 17 patients (23.6%), and rescue cricothyroidotomies were performed in 55 patients (76.4%). Forty-one patients (56.9%) were already in traumatic cardiac arrest during cricothyroidotomy. Thirty-two patients (44.4%) died on scene, and 32 (44.4%) subsequently died in hospital. Five patients (6.9%) survived to hospital discharge, and three patients (4.2%) were lost to follow-up. The most common indication for primary cricothyroidotomy was mechanical entrapment of patients (n=5, 29.4%). Difficult laryngoscopy, predominantly due to airway soiling with blood (n=15, 27.3%) was the most common indication for rescue cricothyroidotomy. The procedure was successful in 97% of cases. During the study period, 6570 prehospital emergency anaesthetics were conducted, of which 30 underwent rescue cricothyroidotomy after failed tracheal ...

The wall of the larynx is supported by four cartilages namely a thyroid cartilage, a cricoid cartilage a pair of arytenoid cartilages. Thyroid cartilage is in the form of a broad ring, lying in the ventral and lateral walls of the pharynx. This cartilage is incomplete dorsally. 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
The median cricothyroid ligament is a flat band of white connective tissue that connects the front parts of the contiguous margins of the cricoid and thyroid cartilages. It is a thick and strong ligament, narrow above and broad below. Each lateral ligament is known as the conus elasticus. The lateral cricothyroid ligament is overlapped on either side by laryngeal muscles. The conus elasticus (which means elastic cone in Latin) is the lateral portion of the cricothyroid ligament. The lateral portions are thinner and lie close under the mucous membrane of the larynx; they extend from the upper border of the cricoid cartilage to the lower margin of the vocal ligaments, with which they are continuous. The vocal ligaments may therefore be regarded as the free borders of each conus elasticus, and extend from the vocal processes of the arytenoid cartilages to the angle of the thyroid cartilage about midway between its upper and lower borders. These anatomical structure have been called in many ...

Laryngeal cancer is relatively uncommon, encompassing around 1% of all cancers. Of these, squamous cell carcinoma accounts for the majority, with a high male:female perponderance (5:1)1. Chondrosarcoma accounts for around one percent2. It usually presents with classic signs and symptoms of a laryngeal tumour; ie dysphonia, inspiratory stridor, dysphagia, odynophagia, neck mass, or persistent cough3. It is usually a slow growing tumour and therefore rarely presents with acute airway obstruction. It is most commonly centred on the cricoid cartilage (70 - 75%), however it can also arise from the thyroid cartilage, epiglottis and arytenoids in descending order of incidence4.. Symptoms depend on the location. Subglottic and endolaryngeal tumours will generally cause dyspnoea. Extralaryngeal tumours may compress the oesophagus resulting in dysphagia5. In our case the patient presented with inspiratory stridor and mild dysphonia, due to its location originating outside of the larynx, ultimately ...
The upper airway consists of the pharynx and the nasal cavities; however, some authors include the larynx and trachea as well. The pharynx is can be divided into the nasopharynx, oropharynx, and laryngopharynx.. The nose is composed of bone and cartilage, which are in turn attached to the facial skeleton. It is a pyramidal structure that is divided by a midline septum into two nasal cavities. The nasal cavities are lined with mucosa that can function to heat and humidify inspired gas. The paranasal sinuses drain into the nasal cavity. The posterior portion of the mouth opens into the oropharynx. When a patient is supine and unconscious, the tongue and lower jaw may slide posteriorly leading to airway obstruction within the oropharynx.. The pharynx is a U-shaped fibromuscular tube that extends from the base of the skull to the cricoid cartilage. It is bounded anteriorly and superiorly by the nasal cavity, followed more inferiorly by the mouth, and then the larynx. These borders divide the pharynx ...
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 normal canine thyroid gland consists of a right lobe, which extends from the caudal border of the cricoid cartilage of the larynx to the level of the 5th tracheal ring, and a slightly more caudal left lobe, which extends from the level of the 3rd to that of the 8th tracheal ring[2]. Infrequently, an isthmus located ventral to the trachea connects the lobes. The right lobe is in close proximity to the common carotid artery, the internal jugular vein, and the vagosympathetic trunk; the left lobe is in close proximity to the caudal laryngeal nerve and the esophagus. Ectopic thyroid tissue occurs frequently, located intrathoracically in the heart and heart base[3]. The parathyroid glands are closely associated with the thyroid gland, with a parathyroid gland frequently being located at the cranial surface of each thyroid lobe, and the second parathyroid gland frequently being embedded within the thyroid tissue. Lymph drains from the thyroid gland in both cranial and caudal directions[4]. Lymph ...
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 ...

The arytenoid cartilage is attached to the cricoid cartilage by small tough ligaments to form what is known as a saddle joint allowing rotation from side to side mainly about its long axis. Because the superior aspect of the posterior cricoid lamina slopes downwards the arytenoid cartilage rotates in a complex way such that the vocal process moves inwards and downwards during phonation and outwards and upwards during breathing. The arytenoids can also tilt forwards and backwards and slide along the length of the cricoarytenoid joint all of which allow fine tuning of the positioning and shaping of the vocal folds and epiglottic funnel both in speaking and singing.. ...
The arytenoid cartilages are paired hyaline cartilages that articulate with the sloping upper border of the lamina of the cricoid cartilage by the cricoarytenoid joint. This joint allows movement of the arytenoid cartilages, which is vital in app...

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. ...
Topographic Relationships Contours and Normal Constrictions of Esophagus, The esophagus begins in the neck as a continuation of the pharynx (cervical esophagus). This point of origin corresponds to the inferior border of the cricoid cartilage and the lower margin of the inferior pharyngeal constrictor muscle, also called the cricopharyngeus muscle, at about the level of the sixth cervical vertebra.

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 ...

. Respiratory 1.The head is relatively large with a prominent occiput, the neck is short and the tongue is large. The airway is prone to obstruction because of these differences. 2.The epiglottis is large, floppy and U shaped. The trachea is short (approximately 4-9cm) 3.The glottic opening (laryngeal opening) is more anterior and the narrowest part of the airway is at the cricoid ring. (In the adult airway the narrowest point is the vocal cords). 4.An uncuffed endotracheal tube which has an air leak around it when positive pressure is applied to it should be used in children under 10 years of age. An uncuffed tube provides a larger internal diameter compared with a cuffed tube. 5. (Age / 2) Increased alveolar ventilation is achieved by an increase in respiratory rate

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 ...
