目的：探讨改良持续腹腔冲洗预防阑尾切除术后腹腔残余感染的临床疗效。方法选取2012年1月-2014年1月于医院接受腹腔镜下阑尾切除术的阑尾炎患者76例。所有患者依照随机、自愿原则分为对照组和观察组各38例。所有患者均接受腹腔镜下阑尾切除术且术后放置橡胶引流管进行腹腔引流，对照组术后采用间断腹腔冲洗，观察组采用持续腹腔冲洗。比较2组患者术后发热天数、白细胞总数（WBC）恢复正常时间以及引流时间。结果观察组术后发热天数[（2.4±0.9）d vs.（4.3±1.3）d]、WBC 恢复正常时间[（3.5±0.6）d vs.（5.7±0.9）d]以及引流时间[（3.6±0.7）d vs.（5.3±0.8）d]均明显小于对照组，差异均有统计学意义（均 P ＜0.05）。结论改良持续腹腔冲洗预防阑尾切除术后腹腔残余感染临床效果显著，可促进患者术后康复，值得临床推广应用。“,”Objective To discuss the clinical effect of improved continuous abdominal cavity flushing to prevent ab-dominal residual infection after appendectomy. Methods 76 patients who will receive appendectomy were divided randomly and voluntarily into the control group(n = 38)and observation group(n = 38). All patients were given appendectomy and ab-dominal cavity drainage after the operation,patients of control group were intermittent abdominal cavity flushing while the ob-servation group were given persistent abdominal cavity flushing. The postoperative fever days,total number of white blood cell (WBC)returned to normal time and drainage time were compared between the two groups. Results The postoperative fever days[(2. 4 ± 0. 9)d vs.(4. 3 ± 1. 3)d],total number of WBC returned to normal time[(3. 5 ± 0. 6)d vs.(5. 7 ± 0. 9)d]and drainage time[(3. 6 ± 0. 7)d vs.(5. 3 ± 0. 8)d]of observation group was obviously smaller than that of control group,the differences were statistically significant(all P < 0. 05). Conclusion The clinical effect of improved continuous abdominal cav-ity flushing to prevent abdominal residual infection after appendectomy is remarkable,it is worth popularization and applica-tion.
