The cricoid cartilage and the oesophagus are not aligned in close to half of adult patients. Therefore, it would be an alternative to the proposed periodical training in mechanical models, which is not practical.
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 intubationrather than to prevent regurgitation. Anatomical variation of the airways among the individuals evaluated might explain the different results.

Minor events, such as nausea, vomiting, pain, or hemodynamic changes may occur manoobra compression of the cricoid cartilage. Besides being ineffective, compression of those structures can interfere with tracheal intubation or cause lesions of the airways 1.
Brock-Utne JG – Is cricoid pressure necessary? Some studies have demonstrated that a naniobra percentage of anesthesiologists and other professionals directly involved with anesthesia do not know how or have difficulties to perform this maneuver correctly 17, This page was last edited on 3 Novemberat The mechanism proposed for Sellick maneuver is based on the supposition that the esophagus is directly behind the cricoid cartilage.
Compression of the cricoid cartilage: current aspects
The force applied on the cricoid cartilage should be enough to occlude the esophagus, without obstructing or hindering ventilation. However, two studies in cadavers demonstrated that the efficacy of the Sellick maneuver is not reduced with the presence of the nasogastric tube 19, Besides, knowledge of the force to be applied, acquired through training in mechanical models, decreased with dw.
Eduardo Toshiyuki Moro Av. Eur J Anaesthesiol, ; One should not forget that the nasogastric tube is not devoid of risks.
The cricoid cartilage pressure maneuver requires knowledge of the anatomy of upper airways and the correct force brp be used. In his original work, Sellick 2 recommends removal of the tube before anesthesia induction.

An additional benefit of cricoid pressure occurs in paralyzed patients in whom gastric insufflation occurs at lower inflation pressures. It does not seem to be significant differences in the incidence of pulmonary aspiration when different sizes of nasogastric tube are used A survey from south-west England.
How could pulmonary aspiration in cases that compression of the cricoid cartilage was applied be explained?
Cricoid pressure – Wikipedia
Retrieved from ” https: According to the authors, cardiovascular changes were similar to those observed during tracheal intubation in awake patients. The neck was fully extended, which accentuates the anterior convexity of the cervical spine and rectifies the esophagus, preventing the lateral dislocation during compression of the cricoid cartilage maneuver.
As all techniques, cricoid pressure has indications, contraindications and side effects. Clinical Anesthesia 6th ed. In this situation, it is possible to ventilate the patient gently only if Sellick maneuver is used properly. In awake individuals, applying more than 20 N on the cricoid cartilage can cause pain, cough and nausea.
Unfortunately, those devices are expensive, difficult maniobfa be acquired by the majority of anesthesiology services in Brazil, and training for maintenance of the ability should be repeated periodically According to the Single Hand technique, the thumb and the middle finger are placed on each side of the cricoid cartilage and the index finger is placed above.
Sellick maneuver requires knowledge of the anatomy of birp upper airways and the correct force to be applied. However, other investigators have found bhrp cricoid pressure does not increase the rate of failed intubation. But according to some studies, Sellick maneuver hinders proper positioning of both devices 38, Vanner RG – Vurp of regurgitation and its prevents with cricoid pressure.
The BURP maneuver backward, upward, rightward pressure on the thyroid cartilage has been considered an interesting option in those cases 33but it should not be mistaken for the maneuver described by Sellick 2. An endoscopic study in anaesthetized patients.
If visualization of the vocal cords with laryngoscopy or ventilation with a face mask is not adequate, one should reduce the force applied and reevaluate the place where pressure is being applied. However, during vomiting, when esophageal pressure can be higher than 60 cmH 2 O, the maneuver should be discontinued due to the risk of esophageal rupture. The objective of the present report was to discuss the indications, technique, complications, and reasons why some authors have refuted the efficacy of this technique.
The necessary force to compress 10 mL of air when the tip of the syringe is closed is approximately 30 N Some believe that cricoid pressure in pediatric population, especially neonates, improves glottic view and aids tracheal intubation apart from its classical role in rapid sequence intubation for aspiration prophylaxis. According to the author: Assessing the force generated with the application of cricoid pressure.
Services on Demand Journal. Applying pressure on the cricoid cartilage increases the tonus of the upper esophageal sphincter 14but decreases the tonus of the lower esophageal sphincter 15suggesting the presence of mechanoreceptors in the pharynx that promote relaxation of this sphincter.
