Semin Anesth Per Med Pain, ; Many did not know the force applied bup described it as “enough”, “enough force to break an egg”, or “varies” Eduardo Toshiyuki Moro Av. 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. To Do or Not Do”.

This association is a good option for the management of difficult airways in patients at risk for aspiration Flexion of the head induced by the force applied indirectly on the cervical spine, decreasing visualization of the glottis, is one of the disadvantages of this maneuver 9.

Sellick described the importance of applying pressure in the cricoid cartilage during anesthesia induction to prevent regurgitation of gastric contents. An additional benefit of cricoid pressure occurs in paralyzed patients in whom gastric insufflation occurs at lower inflation maniiobra.

Cricoid pressure

The proximal esophagus begins at the inferior portion of the cricoid cartilage. Besides being ineffective, compression of those structures can interfere with tracheal intubation or cause lesions of the airways 1.

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 this configuration is to control the lateral movement of the cartilage 2.

However, this effect does not seem to cause gastroesophageal reflux The incorrect use of the maneuver can cause deformity of the cartilage, closure of the vocal cords, and difficulty to ventilate, especially in women. In some cases, visualization of the vocal cords is possible only after external manipulation of structures, such as the cricoid cartilage.


Compression of the cricoid cartilage was initially described by Monro 1: The mechanism proposed for Sellick maneuver is based on the supposition that the esophagus is directly behind the cricoid cartilage.

A balloon to occlude the cardia and prevent gastroesophageal reflux, associated with the nasogastric tube, has been successfully used. 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 The objective of the present report was to discuss the indications, technique, complications, and reasons why some authors have contested the indication of this maneuver.

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. Sellick maneuver is not a risk-free procedure. Besides, can cause deformity of the cricoid cartilage, closure of the vocal cords, and difficulty to ventilate if it is not used properly.

A study with a new nasogastric tube. Prevention of pulmonary aspiration is fundamental, but permeability of the airways is more important.

Cricoid pressure – Wikipedia

Anaesth Intensive Care ; Buep maneuver requires knowledge of the anatomy of the upper airways and the correct force to be applied. Canadian Journal of Anesthesia, 49 5 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. The force applied on ee cricoid cartilage should be enough to occlude the esophagus, without obstructing or hindering ventilation.


The study also evaluated the adequate force to be used according to those professionals.

Anatomical differences among individuals, changes in the anatomy of the airways induced by the maneuver, improper application of the technique, and reduction in the tonus of the inferior esophageal sphincter are the most common reasons suggested to explain the inability of the Sellick maneuver to prevent regurgitation in some cases 8. Brock-Utne JG – Is cricoid pressure necessary? Eur J Anaesthesiol, ; Despite the bburp of the Sellick maneuver in preventing pulmonary aspiration, it does not guarantee protection of the airways in all patients, especially when not used properly.

,aniobra then, the maneuver has been accepted by anesthesiologists as a fundamental step during the rapid sequential technique.

In his original work, Sellick 2 recommends removal of the tube before anesthesia induction. This page was last edited on 3 Novemberat It has been observed that the nasogastric tube does not interfere with the insertion of the laryngeal mask and that the mask does not prevent insertion of the tube. Some cartilaginous structures of the upper airways are “U”-shaped, which is the case of the thyroid cartilage and the trachea.

Compression of the cricoid cartilage: current aspects

Since then, the maneuver has been widely accepted by anesthesiologists as a fundamental step during induction with the rapid sequence technique. Placement of a nasogastric tube before anesthesia in high-risk patients for pulmonary mmaniobra, to drain liquid and gases present in the stomach, is a common practice.
