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 ...

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 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 ...

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. ...
