This paper presents a review of literature dealing with regurgitation and aspiration and reports a study of the incidence of regurgitation and aspiration in surgical and obstetrical anaesthesia. The clinical and pathological findings are described and factors contributing to regurgitation and aspiration are discussed. The anaesthetic factors are described and discussed with reference to the study made by the authors. A comparison follow-up study of one group of patients with a high incidence of regurgitation and aspiration is made with a similar group of patients anaesthetized twenty years ago. A possible reason for the marked decrease in postoperative pulmonary complications is presented.
A subsequent article will present case histories and discuss treatment and sequelae of aspiration during anaesthesia.
