动态调节肛管插入深度对清洁灌肠效果的影响

Effect of dynamic adjustment of the insertion depth on the cleansing enema

目的通过动态调节肛管插入深度，提高清洁肠道效果，减少患者痛苦。方法选择100例需行术前清洁灌肠的泌尿外科患者，随机均分为实验组和对照组各50例。两组均进行清洁灌肠，实验组采用插管深度开始为7～10cm，然后为20～25cm，最后为7—10cm的动态调节插管深度的方法，对照组采用传统灌肠插入法，深度为7—10cm。比较两组灌肠次数、灌肠液量、肠道清洁度及满意度。结果灌肠次数实验组平均（3．44±1．46）次，观察组平均（8．78±1．85）次；每次灌肠液用量实验组平均（797．0±141．0）ml，观察组平均（582．0±145．7）ml，两组比较差异有统计学意义（t分别为16．022，7．498；P〈0．01）；实验组患者肠道清洁度为98．0％，满意度为92．0％，高于对照组的64．0％，52．0％，差异有统计学意义（χ2分别为18．78，19．841；P〈0．01）。两组患者不良反应发生情况比较差异有统计学意义（P〈0．05）。结论动态调节插管深度的清洁灌肠法效果明显优于传统清洁灌肠法，值得在临床推广应用。

Objective -To improve the effect of dynamic adjustment of the insertion depth on the Cleansing enema so as to reduce the suffering of the patients. Methods Totals of 100 patients who required preoperative cleansing enema were selected in this study. The patients were randomly divided into the experimental group （n = 50） and control group （ n = 50）. In experimental group, they received the dynamic adjustment of intubation depth, the intubation depth was 7 - 10 cm at first, then was changed as 20 - 25 cm, at last the depth was 7 - 10 em. In control group, traditional method （the depth was 7 - 10 cm） was adopted. The number of enema, the amount of enema, the intestinal cleanliness and the degree of satisfaction of two groups were compared. Results Compared with the control group, in the experimental group, the times of enema was decreased significantly [ （3.44 ± 1.46） vs （8.78 ± 1.85）, t = 16. 022, P 〈 0.01 ], the amount of enema used in each case was increased significantly [ （797.0 ± 141.0） ml vs （582.0 ± 145.7 ） ml ; t = 7. 498, P 〈 0. 01 ], the intestinal cleanliness （98.0% vs 64.0% ） and the degree of satisfaction （92.0% vs 52.0% ） were improved obviously （ χ2 = 18.78,19. 841, respectively ;P 〈 0.01 ）. Conclusions This cleansing enema discussed in this study which appropriately changes the insertion depth into the anal canal is obviously better than that of traditional method. And such a new method of cleaning enema is worthy of clinical application.
