摘要
目的探究二氧化碳注入联合水交换在肠镜检查中的应用效果。方法选择2018年2至11月新疆军区总医院北京路临床部拟行结肠镜检查的患者190例,随机分为空气组(63例)、水交换组(63例)和联合组(64例)。空气组患者采用常规注气结肠镜检查;水交换组患者采用注水结肠镜检查;联合组患者采用二氧化碳气泵联合注水结肠镜检查。比较三组的结肠镜检查情况、检查后不适症状间的差异。结果水交换组和联合组的退镜时间和麻醉需求率均显著低于空气组,两组的盲插成功率和Boston评分均明显高于空气组(P <0. 05);联合组的退镜时间明显低于水交换组,差异均有统计学意义(P <0. 05)。三组的进镜时间和检出率间均无统计学差异(P>0. 05)。水交换组、联合组检查中及检查后1 h的VAS评分和腹胀评分显著低于空气组(P <0. 05)。检查中,联合组的VAS评分低于水交换组(P <0. 05),两组的腹胀评分比较无统计学差异(P> 0. 05);检查后1 h,联合组的VAS评分和腹胀评分均显著低于水交换组(P <0. 05)。结论二氧化碳注入联合水交换可明显减少退镜时间和麻醉需求,有效改善清洁度,减轻患者的疼痛和腹胀程度。
