摘　　要：目的: 探讨泪小管断裂吻合术留置硬膜外麻醉导管最佳拔管时机。方法: 选取外伤性泪小管断裂行泪小管吻合术62例62眼为观察对象,根据随机数字表法将62例患者分为A,B,C三组,A,B组各21例21眼,C组20例20眼,所有患者均接受泪小管断裂吻合术,泪道硬膜外麻醉导管拔管时间A组为术后1mo,B组为术后2mo,C组为术后3mo。比较各组患者治疗效果及手术并发症情况。结果: 术后三组患者治疗效果比较,差异均无显著性(P>0.05);与组A及组B比较,组C患者术后下泪点外翻及泪小管炎的比例显著升高,且差异具有显著性(P<0.05)。结论: 泪小管断裂吻合术采用硬膜外麻醉导管作为支撑物时术后1mo为最佳拔管时机,既保证了治疗效果,减少了并发症,又缩短了患者因留置导管带来生活不便的时间。·AIM-To investigate the extubation time of indwelling epidural catheter in canalicular anastomosis.· METHODS- Sixty-two patients （62 eyes） with traumatic lacerations of lacrimal canaliculi underwent canalicular anastomosis were divided into groups A, B, C according to the random number table. All patients received epidural anesthesia catheter canalicular anastomosis, the lacrimal extubation time in group A, B, C were 1 month, 2, 3 months after surgery. The outcomes and surgical complications of patients were compared. · RESULTS; After surgery, there were no significant differences between the therapeutic effect of three groups （P〉 0. 05）. Compared with groups A and B, the proportion of tears point valgus and canalicular inflammation in group C were much significantly higher （P〈0.05）. ·CONCLUSION： One month is the best extubation time for indwelling epidural catheter in canalicutar anastomosis. It can not only ensure the therapeutic effect, reduce complications, but also shorten the inconvenience time caused by indwelling catheters.
