摘要

目的:分析在心脏手术中,骨蜡用于胸骨正中切口胸骨断面填塞止血的必要性。

方法:连续入选2011-01至2014-12期间共445例患者,其中210例患者的胸骨断面使用骨蜡(骨蜡组),235例患者的胸骨断面未使用骨蜡(无骨蜡组)。分别比较两组患者的二次开胸止血情况以及12小时、24小时及总的引流量,关胸时间和输血率。

结果:骨蜡组和无骨蜡组分别有2例和1例患者二次开胸止血,但与骨髓腔出血无关。两组患者的12小时、24小时及总引流量分别为(451±240)ml和 (483±238)ml、(615±304)ml 和(639±285)ml、(842±467)ml和(842±364)ml(P均>0.05)。骨蜡组和无骨蜡组关胸时间分别为(68.0±23.0)min和(66.0±19.0)min(P>0.05)。骨蜡组和无骨蜡组总输血率分别是21%和19%(P>0.05)。

结论:胸骨断面骨蜡的使用不会显著减少关胸后的引流量,也不会影响关胸速度。应舍弃骨蜡在胸骨断面止血中的应用。

Objective: To explore the necessity for application of bone wax stanching bleeding at sternal edge in cardiac surgery by median sternotomy.

Methods: A total of 445 patients who receive cardiac surgery by the same surgeon performing median sternotomy in our hospital from 2011-01 to 2014-12 were studied. According to application of bone wax stanching bleeding, the patients were divided into 2 groups: Bone wax group, n=210 and Non-bone wax group, n=235. Re-thoracotomy for hemostasis, 12 h, 24 h and total draining volume after the operation and time of closing incision were compared between 2 groups.

Results: There were 2 patients and 1 patient received re-thoracotomy for hemostasis in Bone wax group and Non-bone wax group respectively, which was not related to bone marrow cavity bleeding. In Bone wax group and Non-bone wax group,the draining volume at 12 h post-operation were (451 ± 240) ml vs (483 ± 238) ml, at 24 h post-operation were (615 ± 304) ml vs (639 ± 285) ml and the total volume were (842 ± 467) ml vs (842 ± 364) ml, all P>0.05; the time of closing incision were (68.0 ± 23.0 ) min vs (66.0 ± 19.0 ) min, P>0.05; the total transfusion rates were 21% vs 19%, P>0.05.

Conclusion: Application of bone wax at sternum edge could neither affecting the drainage nor the speed of closing incision in cardiac surgery and therefore, it might be given up.

临床上对于心脏外科正中开胸的患者,通常使用骨蜡来填塞胸骨断面以减少出血。但骨蜡会影响胸骨的稳定性,是导致胸骨正中伤口延迟愈合或不愈合的重要因素之一。既然骨蜡有这样的负面作用,那么它带来的止血作用确实比不用骨蜡填塞胸骨好吗?临床上有没有必要继续使用它呢?本文回顾性地分析了使用骨蜡和不使用骨蜡患者术后资料来回答这个问题。

1 资料与方法

临床资料:自2011-01至2014-12期间,连续入选由同一名医生进行开关胸操作的445例患者(排除再次手术患者以及术后需要主动脉内球囊反搏或左心室辅助的患者)。……
