oa Southern African Journal of Anaesthesia and Analgesia - Cricoid pressure : friend or foe? : SASA 2009 Congress prize entries
Cricoid pressure was popularised by Sellick in 1961 as a simple method to reduce the risk of aspiration during induction of anaesthesia. It has since become the standard of care for most anaesthetists. Although it appears to be a mechanically simple and anatomically correct manoeuver, it is in fact complex and difficult to perform optimally. There is also continued controversy regarding its safety and efficacy. Understanding the role of cricoid pressure in our practice requires knowledge of anatomic relationships, physiology of regurgitation, modes of application, timing, amount of force required to apply it effectively and the impact of cricoid pressure on airway management.
