Sleep deprivation is one of the various stress factors which may affect the efficiency of an anaesthitist. Cognitive functions play a vital role in safe anaesthetic practice. To assess the effect of sleep deprivation on cognitive functions, forty anaesthesia residents were tested using various tests in two planned situations. 'Situation I' comprised of non sleep deprived state and 'Situation II' was the sleep deprived state defined as 'less than 4 hours of sleep in the last 24 hours'. The tests used were Trail making task, Digit symbol test, Letter comparison test and Standard progressive matrices. There was a statistically significant decrease in the performance scores after sleep deprivation. It is concluded that acute sleep deprivation adversely affects cognitive functions.
