However, two studies in cadavers demonstrated that the efficacy of the Sellick maneuver is not reduced with the presence of the nasogastric tube 19, J Emerg Trauma Shock. Endoscopic and radiological studies, as well as patients who presented pulmonary aspiration, despite the use of the Sellick maneuver, have raised doubts on the usefulness of the technique.

It does not seem to be significant differences in the incidence of pulmonary aspiration when different sizes of nasogastric tube are used Sellick BA – Cricoid pressure to control regurgitation of stomach contents during induction of anesthesia. A study with a new nasogastric tube.

One should brp forget that the nasogastric tube is not devoid of risks. Vanner RG – Mechanisms of regurgitation and its prevents with cricoid pressure. Airway obstruction with cricoids pressure. 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 – Wikipedia

An assessment and survey of its practice. Canadian Journal of Anesthesia.


Thus, during anesthetic induction, while the patient is awake, 10 to 20 N should be applied, and 30 to 40 N when the patient is unconscious Many did not know the force applied or described it as “enough”, “enough force to break an egg”, or “varies” Besides being ineffective, compression dw those structures can interfere with tracheal intubation or cause lesions of buep airways 1.

When the difficult to manage airways is only noticed after general anesthesia induction, ventilation with a face mask would be recommended immediately, but one should be careful with the patient on a full stomach. Cricoid pressure should not be confused with the “BURP” Backwards Upwards Rightwards Pressure manoeuvre, maiobra is used to improve the view of the glottis during laryngoscopy and tracheal intubationrather than to prevent regurgitation.

Answers varied from 1 to 44N, for awake patients, and 2 to 80 N, for unconscious patients. The BURP maneuver, when used in combination with Sellick maneuver, can hinder visualization of the glottis.

Sellick described the importance of applying pressure in the cricoid cartilage during anesthesia induction to prevent regurgitation of gastric contents. The effect of cricoids pressure on the cricoids cartilage and vocal cords: 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.

An endoscopic study in anaesthetized patients. According to the authors, cardiovascular changes were similar to those observed during tracheal intubation in awake patients. In some cases, visualization of the vocal cords is possible only after external manipulation of structures, such as the cricoid cartilage. They were placed in the supine position, lowering the torso slightly to avoid aspiration of regurgitated material.

Unfortunately, those devices are expensive, difficult to be acquired by the majority of anesthesiology services in Brazil, and training for maintenance of the ability should be repeated periodically Sellick maneuver is not a risk-free procedure. Curr Opin Anaesthesiol, ; Dw of the head induced by the force applied mahiobra on the cervical spine, decreasing visualization of the glottis, is one of the disadvantages of this maneuver 9.


From the decade of on, studies on compression of the cricoid cartilage started focusing on the force that should be applied and not on gastric pressure. Anatomical variation of the airways among the individuals evaluated might explain the different results.

Cricoid pressure

Services on Demand Journal. The mechanism proposed for Sellick maneuver is based on the supposition that the esophagus is directly behind the cricoid cartilage. Cricoid pressure may displace the esophagus dr, make ventilation with a facemask or with an laryngeal mask airway LMA more difficult, interfere with LMA placement and advancement of a tracheal tube and alter laryngeal visualization by a flexible bronchoscope.

A survey from south-west England. Besides, knowledge of the force to be applied, acquired through training in mechanical models, decreased d time. Vanner e Pryle 19 observed manobra 30 N equivalent to 3 kg was the necessary force that should be applied on the cricoid cartilage to prevent regurgitation of NS in 10 cadavers with esophageal pressure of up to 55 cmH 2 O.

Compression of the cricoid cartilage was initially described by Monro 1:
