This association is a good option for the management of difficult airways in patients at risk for aspiration Several suggestions have been made to habilitate anesthesiologists to apply the Sellick maneuver properly: Vanner e Pryle 19 observed that 30 N equivalent to 3 kg was mniobra 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.
Despite the importance of the Sellick maneuver in preventing pulmonary aspiration, it does not guarantee protection of the airways in all patients, especially when not used properly. The model was considered an effective training, but the duration of the ability acquired decreased significantly after one month.
As all techniques, cricoid pressure has indications, contraindications and side effects. The proximal esophagus begins at the inferior portion of the cricoid cartilage. The study also evaluated the adequate force to be used according to those professionals.
Cricoid pressure – Wikipedia
According to the authors, cardiovascular changes were similar to those observed during tracheal intubation in awake patients. Flexion of the head induced by the force applied indirectly butp the cervical spine, decreasing visualization of the glottis, is one of the disadvantages of this maneuver 9.
Auditing the application of cricoid pressure.
However, the so-called “olfactory position” flexion of the neck associated with hyperextension of the atlanto-occipital joint is currently deemed more adequate for ventilation and tracheal intubation The cricoid cartilage pressure maneuver requires knowledge of the anatomy of upper airways and the correct force to be used.
On the original study of Sellick 226 patients deemed to be at risk for pulmonary aspiration of gastric contents were evaluated.

Views Read Edit View history. The technique involves the application of backward pressure on the cricoid cartilage with a force of newtons  to occlude the esophaguspreventing aspiration of gastric contents during induction of anesthesia and in maniobrz of emergency victims when intubation is delayed or not possible. Cricoid force greater than 40 N can compromise airway patency and make dw intubation difficult. Since then, the maneuver has been widely accepted by anesthesiologists as a fundamental step during induction with the rapid sequence technique.
Rev Bras Anestesiol, ; Br J Anaesth, ; The force applied should be enough to prevent aspiration, but not high enough to cause obstruction of the airways or esophageal rupture in case of vomiting Priebe HJ – Cricoid pressure: The Two Hands manibora is an alternative for compression of the cricoid cartilage.
Compression of the cricoid cartilage: current aspects
Compression of the cricoid cartilage. Acta Anaesthesiol Scand, A study with a new nasogastric tube.
InFanning was the first author to study the intragastric pressure required to overcome the force generated by cricoid cartilage compression. Sellick maneuver, rapid sequence.
Despite the importance given to Sellick maneuver in preventing pulmonary aspiration, there are no guarantees it will protect the airways of all patients, especially when the technique is not properly used. Just feel the force Besides, can cause deformity of the cricoid cartilage, closure of the vocal cords, and difficulty to ventilate if it is not used properly.
However, other investigators have found that cricoid pressure does not increase the rate of failed intubation. The cricoid cartilage and the oesophagus are not aligned in close to half of adult patients. Curr Opin Anaesthesiol, ds Compression of the cricoid cartilage was initially described by Monro 1:
