Abstract
Since the danger of pulmonary aspiration was recognized in the 1930s in obstetric anaesthesia,1 and Mendelson established its aetiology in 1946,2 efforts have been made to reduce its incidence: fasting before anaesthesia, prophylactic medication (such as antacids or H2 antagonists), rapid-sequence induction of anaesthesia with application of cricoid pressure, and the use of a cuffed tracheal tube.
