Objective:To investigate the safety,feasibility and recent clinical efficacy of modified and traditional closing thoracic cavity in thoracic surgery.Methods:From March 2014 to November 2015,81 patients underwent tho-racic surgery.After thoracic surgery was done,the modified and traditional closing thoracic cavity would be finished by the same doctor.Post -thoracotomy pain is evaluated with the method of visual analogue scale(VAS).Results:The time of closing thoracic cavity in modified group (16.6 ±1.42)min was significantly shorter than that in the tradition-al group (18.1 ±1.56)min(P <0.000 1).The VAS of 24 hours,72 hours in modified group(5.77 ±1.34,3.54 ± 0.85,3.08 ±0.75)were significantly lower than that in the traditional group (6.33 ±1.07,4.10 ±0.82,3.84 ± 0.95)(P <0.05).There were no significant differences in amount of thoracic cavity drainage[(166.67 ±62.17)ml vs (174.76 ±76.07)ml],postopaertive chest drainage extubation time[(4.90 ±1.85)d vs (5.17 ±1.56)d]or to-tal postoperative complications(6 /39,15.4% vs 7 /42,16.7%).Conclusion:Modified closing thoracic cavity in tho-racic surgery is technically safe and feasible.%目的：探讨开胸术后不关肋间的改良关胸方法和传统关胸方法的安全性、可行性及近期临床疗效。方法：选择我院2014年3月至2015年11月施行开胸手术的患者81例，术后由同一名主治医师关胸，采用不关肋间的改良关胸方法闭合胸腔39例（试验组），传统关胸方法闭合胸腔42例（对照组），两组术后早期胸部镇痛用硬膜外阻滞，应用自控止痛泵的方法。记录两组关胸时间，观察两组患者术后24小时、72小时的疼痛情况（视觉模拟评分法 VAS 评分）、胸腔引流量、拔管时间以及切口和肺部并发症的发生情况。结果：不关肋间的改良关胸方法关胸所用时间（16．6±1．42）min 显著短于传统关胸组（18．1±1．56）min（P ＜0．0001）；术后24小时、72小时以及术后1个月的 VAS 评分（5．77±1．34、3．54±0．85、3．08±0．75）均显著小于传统关胸组（6．33±1．07、4．10±0．82、3．84±0．95）（P ＜0．05）；两组术后胸腔引流量[（166．67±62．17）ml vs （174．76±76．07）ml]、术后胸腔引流时间[（4．90±1．85）天 vs （5．17±1．56）天]、术后并发症发生率（6／39，15．4％ vs 7／42，16．7％）等方面差异无统计学意义（P ＞0．05）。结论：不关肋间的改良关胸方法术在技术上是安全、可行的，可以减少关胸时间，改善患者术后疼痛情况。
