结肠直肠手术的传统术前准备方法系限制饮食、口服泻药及清洁灌肠。此法耗时至少2～3天。由于限制饮食,常引起病人体力消耗,造成的负氮平衡可达5克之多。反复灌肠增加病人痛苦,肠管的清洁程度也往往不能令人满意。自1981年8月起,我们改用口服10％甘露醇,全肠灌洗,作为术前准备,取得了较为满意的效果,现介绍如下。 Traditional methods of preoperative preparation of colorectal surgery limit the diet, oral laxatives and cleansing enemas. This method takes at least 2 to 3 days. Due to diet restrictions, patients often cause physical exertion, resulting in negative nitrogen balance of up to 5 grams. Repeated enema increases patient pain, bowel cleanliness is often not satisfactory. Since August 1981, we switched to oral administration of 10% mannitol, total bowel irrigation, as preoperative preparation, and achieved satisfactory results are presented below.
