Bowel preparation by conventional methods is time-consuming and unpleasant for both patient and staff. In addition, it requires admission to hospital several days before surgery. Preparation using oral polyethylene glycol solution is more acceptable and can easily be adapted so that the patient can perform the procedure at home before admission to hospital. In a prospective series we have compared the efficacy of preparation at home using polyethylene glycol with similar preparation in hospital and with a standard bowel preparation based on magnesium sulphate. Preparation was better after polyethylene glycol and this was significant when performed at home (P less than 0.01). There was no effect on either electrolytes or haematological parameters, but polyethylene glycol did result in a rise in the number of colonic Streptococcus faecalis seen. This rise was not seen with magnesium sulphate (P less than 0.001).
传统方法进行肠道准备对患者和医护人员来说都既耗时又难受。此外，还需要在手术前几天住院。使用口服聚乙二醇溶液进行准备更易被接受，并且可以轻松调整，以便患者在入院前在家中就能完成该程序。在一个前瞻性系列研究中，我们比较了在家中使用聚乙二醇进行准备与在医院进行类似准备以及基于硫酸镁的标准肠道准备的效果。聚乙二醇准备后的效果更好，在家中进行时差异显著（P小于0.01）。对电解质或血液学参数均无影响，但聚乙二醇确实导致所见结肠粪肠球菌数量增加。使用硫酸镁时未出现这种增加（P小于0.001）。
