摘要目的 探讨麻醉结肠镜检查前行分次肠道准备和传统单次肠道准备患者胃液残余量(GRV)的差异.方法 连续选取2016年10月8日至12月30日行择期性同日麻醉胃镜及结肠镜检查的门诊患者,分成传统单次肠道准备组和分次肠道准备组.比较两组患者的GRV和肠道准备质量情况.统计学方法采用t检验,并以多元线性回归分析GRV的影响因素.结果 共纳入121例患者,其中分次肠道准备组60例,传统单次肠道准备组61例.分次肠道准备组的GRV为(17.3±12.2) mL,低于传统单次肠道准备组的(23.7±14.6) mL,差异有统计学意义(t=2.642,P=0.009).分次肠道准备组的肠道准备质量评分为(8.05±0.85)分,高于传统单次肠道准备组的(7.67±1.19)分,差异有统计学意义(t=-2.002,P=o.048).空腹时间与GRV有关(OR=1.732,95％CI 0.299～3.168,P=0.018).结论 麻醉结肠镜检查前行分次肠道准备患者的GRV低于传统单次肠道准备患者,因而不会增加麻醉误吸的风险.

abstractsObjective To explore the difference in gastric residual volume (GRV) between singledose and split-dose bowel preparation before colonoscopy under general anesthesia.Methods From October 8th to December 30th in 2016,the out-patients undergoing gastroscopy and colonoscopy with anesthesia services on the same day were selected and divided into the traditional single-dose bowel preparation group and split-dose bowel preparation group.The GRV and intestinal preparation quality were compared between the two groups.T test was used for statistical analysis and multiple linear regression analysis was performed for the influence factors of GRV analysis.Results A total of 121 patients were enrolled,60 patients in the spilt-dose bowel preparation group and 61 in the traditional single-dose bowel preparation group.The mean GRV of the split-dose bowel preparation group was (17.3 ± 12.2) mL,which was lower than that of the single-dose bowel preparation group ((23.7 ± 14.6) mL),and the difference was statistically significant (t =2.642,P=0.009).The score of intestinal preparation quality of the split-dose bowel preparation group was 8.05 ± 0.85,which was higher than that of the single-dose bowel preparation group (7.67±1.19),and the difference was statistically significant (t =-2.002,P=0.048).Fasting time was related with GRV (odd ratios (OR)=1.732,95％ contidence interval (CI) O.299 to 3.168,P=0.018).Conclusion The GRV of patients with split-dose bowel preparation before colonoscopy is lower than that of traditional single-dose bowel preparation,thus reducing the risk of aspiration during anesthesia.
