不同清洗消毒方法对结肠镜检查化学性肠炎发生率的影响

摘要

目的 探讨不同清洗消毒方法对结肠镜检查引起化学性肠炎的影响.方法 选择结肠镜检查中行结肠息肉取检,3～4d再次行结肠镜下息肉电切术患者630例,根据结肠镜不同清洗方法分为人工清洗消毒组205例,全自动机器清洗消毒组216例,全自动机器清洗消毒后再人工冲洗联合组209例,分析3种不同清洗消毒方法结肠镜检查致化学性肠炎的发生率.结果 人工组患者化学性肠炎发生率为2.9％,机器组发生率为4.2％,联合组为0.0％,3组之间化学性肠炎的发生率比较差异有统计学意义(x2 =8.2,P＜0.01)；组间两两比较中联合组化学性肠炎的发生率较人工组及机器组的低,两组比较差异有统计学意义(x2分别为4.3,7.0;P ＜0.05)；人工组与机器组的化学性肠炎发生率比较差异无统计学意义(x2 =0.47,P＞0.05).结论 全自动清洗消毒机清洗消毒后加人工冲洗,能有效预防结肠镜检查引起的化学性肠炎的发生.%Objective To investigate the effect of different methods of cleaning and disinfection on the incidence of colonoscopy induced chemistry enteritis.Methods Totals of 630 cases using three different methods of cleaning and disinfection including artificial cleaning and disinfection (group A,n =205),automatic cleaning and dis-infection and artificial cleaning(group B,n =216) and disinfection after automatic cleaning and disinfection(group C,n =209) from June 2009 to June 2012.Then,the incidence of colonoscopy induced chemistry enteritis in three groups were observed.Results The gender and age of three groups were no significant difference (P ＞ 0.05).The difference in the incidence of chemistry enteritis in group A (2.9％),group B(4.2％),and group C(0.0％)was statistically significant (x2 =8.2,P ＜ 0.01).The incidence of chemistry enteritis of group C was significantly lower than that of group A and group B (x2 =4.3,7.0,respectively;P ＜ 0.05),but the incidence of chemistry enteritis of artifical group (group A) and automation group(group B) was no significantly different (x2 =0.47,P ＞0.05).Conclusions Artificial cleaning and disinfection after automatic cleaning and disinfection can effectively prevent the chemistry enteritis incidence.
