A randomised comparison of three drainage systems following cholecystectomy . The efficacy of low pressure , high pressure and passive drainage systems have been compared after cholecystectomy . Symptoms of pain , discomfort and nausea were compared using linear analogue scales and spirometry was used to examine pre-operative and postoperative respiratory function . The low pressure suction drain removed an intraperitoneal marker , gentamicin , more effectively than the high pressure suction drain , but not more effectively than the passive drain . There were no differences in postoperative respiratory function nor in the amount of pain or discomfort between the groups . The passive drain group reported less nausea than the suction drain groups . If a negative pressure drainage system is to be used , a low pressure suction drain should be used in preference to a high pressure system .
