INCIDENCE OF INTRAOPERATIVE AWARENESS DURING GENERAL ANAESTHESIA AND ANALYSIS OF PROBABLE RISK FACTORS

Abstract :

 BACKGROUND: Accidental awareness during intended general anaesthesia with postoperative explicit recall can be a devastating experience for patients, frequently leading to post traumatic stress disorder. The low incidence of awareness during anaesthesia makes it difficult to assess risk factors and even current prospective cohort studies have problems identifying exact causes. Recently, cases of awareness reported by the fifth National Audit Project (NAP5), suggests that the current incidence in the UK is about 1 in 15,000. This is much lower than the 1 to 2 per 1,000 incidences that has been found in several prospective studies that have assessed awareness with recall. This study has been undertaken to estimate the incidence of accidental awareness during general anaesthesia in our hospital and to analyse the probable risk factors by interviewing the patients after recovery from general anaesthesia.

METHODOLOGY: A total of 750 patients who underwent diverse surgeries under general anaesthesia over a three month period were assessed. Perioperative data and intraoperative drugs were collected prospectively for logistic regression analysis. Patients were interviewed twenty four and forty eight hours after recovery from general anaesthesia. The structured interview was done by the research staff, based on the Brice Questionnaire and descriptive analysis was done by a blinded team for unintended awareness.

RESULTS: None of the 750 patients reported awareness or possible awareness. Only one female patient reported pleasant dreaming after short duration of propofol anaesthesia.

CONCLUSIONS: This study was the first in our hospital attempted to identify cases of awareness. The incidence of conscious awareness following the general anaesthesia protocol in our hospital was found to be negligible when interviewed up to second postoperative day. Based on the existing literature, we have also made a ief review of the risk factors of awareness and the strategies to be implemented to prevent the same.
