早期拔除引流管对脊柱后路手术并发硬脊膜破裂者的影响

摘要

Objective To study the clinical effects of shortening the drainage time for patients with dural tears after posterior spinal sur -gery.Methods A total of 120 patients with dural tears after posterior spinal surgery were randomly divided into study group and control group,60 patients in each group .Patients in control group had wound drainage tubes removed after 5 days and patients in study group had wound drainage tubes removed after 3 days.The disappearance time of leakage ,incision healing time and complication rate were compared between two groups.Results The disappearance time of leakage in study group was (13.7 ±3.8)days which was significantly less than (20.0 ±5.1)days in control group(P<0.05).The incision healing time in study group was (22.7 ±4.9)days which has no significant difference with (23.9 ± 5.7)days in control group.The postoperative infection rate was 3.3%(2/60) which was significantly less than 20.0%(12/60) in control group(P<0.01).Conclusion Shortening drainage time can decrease the disappearance time of leakage and postoperative infection rate .%目的：探讨早期拔除引流管对脊柱后路手术并发硬脊膜破裂者的影响。方法脊柱后路手术并发硬脊膜破裂患者120例，随机分为观察组和对照组，每组60例。对照组患者采用常规术后5 d拔除引流管及更换切口敷料治疗，观察组患者采用术后3d拔除引流管及更换切口敷料治疗。比较2组患者术后脑脊液漏消失时间、切口愈合时间和术后并发症发生率。结果观察组患者脑脊液漏消失时间为（13．7±3．8）d，显著低于对照组的（20．0±5．1）d（P＜0．05）。观察组患者切口愈合时间为（22．7±4．9）d，与对照组的（23．9±5．7） d比较，差异无统计学意义（P＞0．05）。观察组患者感染发生率为3．3％（2／60），显著低于对照组的20．0％（12／60），差异具有统计学意义（P＜0．01）。结论早期拔除引流管有助于缩短脑脊液漏消失时间并降低术后感染的发生率。
