However, other investigators have found that cricoid pressure does not increase the rate of failed intubation.

As all techniques, cricoid pressure has indications, contraindications and side effects.

Beginning around 2000, a significant body of evidence has accumulated which questions the effectiveness of cricoid pressure.

Recent research increasingly suggests that cricoid pressure may not be as advantageous as once thought.

Cricoid pressure has been widely used during rapid sequence induction for nearly fifty years, despite a lack of compelling evidence to support this practice.

Cricoid pressure may frequently be applied incorrectly.

Anterior cricoid pressure was considered the standard of care during Rapid Sequence Intubation for many years.

Based on the current literature, the widespread recommendation that cricoid pressure be applied during every rapid sequence intubation is quickly falling out of favor.

Cricoid pressure may frequently displace the esophagus laterally, instead of compressing it as described by Sellick.

Some clinicians believe the use of cricoid pressure should be abandoned because of the lack of scientific evidence of benefit and possible complications.

Cricoid pressure may also compress the glottis, which can obstruct the view of the laryngoscopist and actually cause a delay in securing the airway.

An additional benefit of cricoid pressure occurs in paralyzed patients in whom gastric insufflation occurs at lower inflation pressures.

Cricoid pressure is often confused with the "BURP" (Backwards Upwards Rightwards Pressure) maneuver.

The American Heart Association still advocates the use of cricoid pressure during resuscitation using a BVM, and during emergent oral endotracheal intubation.

A study concluded that appropriate application of cricoid pressure prevents gastric gas insufflation during airway management via mask up to 40 cm H2O PIP in infants and children.

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.

Named for British anesthetist Brian Arthur Sellick (1918-1996) who first described the procedure in 1961, the goal of cricoid pressure is to minimize the possibility of regurgitation and pulmonary aspiration of gastric contents.

Another key feature of RSI is the application of manual 'cricoid pressure' to the cricoid cartilage, often referred to as the "Sellick maneuver", prior to instrumentation of the airway and intubation of the trachea.

Nevertheless, the "Sellick maneuver" (application of cricoid pressure) is often applied to reduce the risk of aspiration of gastric contents whenever possible until the trachea can be intubated or until there is no longer any need for positive pressure ventilation.

The initial proposal of cricoid pressure as a useful clinical procedure, its subsequent adoption as the lynchpin of patient safety, and its current decline into disfavor represents a classic example of the need for evidence-based medicine, and the evolution of medical practice.

Cricoid pressure, also known by the eponymous name of the Sellick manoeuvre (maneuver in American English), is a technique applied during endotracheal intubation, used to either prevent regurgitation, or to assist with visualisation of the glottis by a practitioner attempting intubation.

Cricoid pressure may displace the esophagus, 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.

In 1961 Dr. 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 of cricoid pressure for the prevention of regurgitation.

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.
