目的

探讨在结肠镜检查时肠道准备不充分患者使用肠道清洁剂进行冲洗的效果。

方法

回顾性分析2018 年1 月至2024 年6 月联勤保障部队第九八〇医院行结肠镜检查中肠道准备不充分并采取镜下冲洗的患者76 例并分为两组。 研究组42 例，结肠镜检查前使用肠道清洁剂（复方聚乙二醇电解质散：浓度1A+1B 溶于125 ml 温水；芒硝：浓度25 g 溶于1 000 ml 温水）进行冲洗；对照组34 例，使用生理盐水或无菌注射用水进行冲洗。 比较两组间冲洗前的波士顿肠道准备评分、操作时间、检查目标完成率并总结护理经验。

结果

两组间性别、年龄无统计学差异。 76 例患者中急诊结肠镜检查54 例（71.1%）、常规检查15 例（19.7%）、息肉切除7 例（9.2%）。 研究组使用复方聚乙二醇电解质散23 例（54.8%）、芒硝19 例（45.2%）。 操作前研究组肠道准备评分2.02±0.81，对照组评分1.74±0.75，无明显统计学差异。 研究组操作时间平均 （54.58±12.80） min；对照组平均（66.98±16.38） min，统计学有明显差异。 研究组40 例完成目标肠道检查，对照组6 例择期再次行肠道准备，检查完成率为95.2%：82.4%。

结论

结肠镜检查过程中对肠道准备不充分的患者使用常规清肠剂进行冲洗的补救措施且完成结肠镜检查，具有缩短操作时间、检查完成率高等优点。

Objective

To explore the effectiveness of flushing laxative medications solution under colonscopy as a remedial measure to achieve the purpose of examination in patients with inadequate bowel preparation during colonoscopy.

Method

A retrospective analysis of 76 patients who underwent colonoscopy at the 980th Hospital of the Joint Logistics Support Force between January 2018 and June 2024 and were found to have inadequate bowel preparation，with subsequent endoscopic rescue measures taken.The study subjects were divided into an experimental group and a control group based on whether they were flushing laxative medications solution under colonscopy or not.The experimental group and the control group were flushed with laxative medications solution and physiological saline，respectively.Compare the Boston bowel preparation scores，operation time，completion rate of examination targets，and summarize nursing experience between two groups.

Result

42 cases were included in the experimental group and 34 cases were included in the control group.There was no statistical difference in gender and age between the two groups.Among the patients included，54 cases （71.1%） underwent emergency colonoscopy，15 cases （19.7%） underwent routine examination，and 7 cases （9.2%） underwent polypectomy.In the experimental group，23 cases（54.8%） used compound polyethylene glycol electrolyte，and 19 cases （45.2%） used magnesium sulfate.The bowel preparation score for the experimental group was 2.02±0.81，while the control group's score was 1.74±0.75，with no significant statistical difference between the two groups.The average time for colonoscopy in the experimental group was 54.58 ± 12.80 minutes； The average time consumption of the control group was 66.98 ± 16.38 minutes，and there was a significant statistical difference in surgical time between the two groups.The completion rate of colonoscopy target examination of the experimental group was 95.2% and control group was 82.4%，with a statistically significant difference between the two groups.

Conclusion

The remedial measure of flushing laxative medications solution in patients with inadequately prepared colon during colonoscopy has the advantages of shortening operation time and high completion rate of examination，but it demands higher standards of nursing care.
