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.
在胆囊切除术后，对低压、高压和被动引流系统的疗效进行了比较。使用线性模拟量表比较疼痛、不适和恶心症状，并采用肺活量测定法检查术前和术后的呼吸功能。低压吸引引流比高压吸引引流更有效地清除了腹腔内标记物庆大霉素，但并不比被动引流更有效。各组之间术后呼吸功能、疼痛或不适程度均无差异。被动引流组报告的恶心症状比吸引引流组少。如果要使用负压引流系统，应优先选择低压吸引引流而非高压系统。
