Sleep deprivation among surgical residents: Does it affect performance while practising a laparoscopic intestinal anastomosis?

INTRODUCTION: To assess the impact of fatigue due to incorrect night rest in the performance of a laparoscopic manual anastomosis. METHODS: A prospective study evaluating the results from the realization of a manual endotrainer entero-enteral anastomosis performed by residents in terms of fatigue caused by inadequate nightly rest. Two groups were established; the FATIGUE group (F): anastomosis performed by residents coming off shift who slept less than seven hours and the REST group(R), being those who slept at home for more than 7 h. The time taken, length of the anastomosis and quality of such were compared based on 4 parameters: Air leak test, correct tension on the suture line, accurate opposition of the edges and optimal distance between stitches. RESULTS: 402 anastomoses were studied (211 rest group, 191 fatigue group). In the fatigue group leaks were detected in 33.5% anastomoses, as opposed to 19.4% in the rest group (P < .01). El rest group performed the anastomosis in 56.75 min and the fatigue group in 61,49 min (P = .006). There were no significant differences in the others parameters. CONCLUSIONS: Fatigue increases the risk of leakage and the time to do the exercise.
