Recollections of general anaesthesia: a survey of anaesthesiological practice.

Abstract

In order to identify the factors to which patients attach importance when undergoing general anaesthesia, 678 patients were retrospectively asked about their recollections of previous anaesthetics during routine preoperative screening over a period of 14 months. The most frequently mentioned recollections concerned the post-anaesthetic period, followed by recollections of the induction of anaesthesia. From the post-anaesthetic period, nausea/vomiting and drowsiness were most often cited. The number of anaesthetics previously undergone had no influence on the reports of the two most frequently mentioned complaints. The rate of nausea/vomiting in this series was 21.0%. The number of patients reporting nausea/vomiting following an anaesthetic has not changed over the years. The last 250 patients were asked to assess the quality of their anaesthetics on a 5-point scale. More than a quarter of the patients were not satisfied with the anaesthesia. No correlation was found between the assessment of the anaesthesia and complaints about nausea/vomiting and drowsiness. The possible role of psychological factors in the origin of complaints about anaesthesia is discussed.
