[Cricoid pressure--safety necessity or unnecessary risk?].
Cricoid pressure is a simple and effective measure to prevent regurgitation of gastric juice and content. This procedure, which prevents a possible reflux by compression of the oesophagus between the cricoid cartilage and the cervical vertebral bodies, is generally acknowledged in clinical practice, although there is lack of scientific evidence regarding its effect on the outcome of patients at risk of aspiration. However, there is only a rare incidence of complications as long as cricoid pressure is used with exact indication, considering the contraindications and correct performance. Especially important are the optimal force applied on the cricoid and the duration of application. However, there is a lot of evidence in the literature that the knowledge of anaesthetists about the method and technique of cricoid pressure is rather unsatisfactory. Thus, the starting point for improving the efficiency and safety of cricoid pressure seems to be better teaching and training.
