摘 要:目的总结一种新的技术在心脏术后纵隔感染的应用经验。方法回顾性分析2017年2月—2019年6月15日心脏术后发生纵膈感染成人患者,共有5例(1.2%),其中男性4例,女性1例,平均年龄(49±19)岁,平均体质量(70±15)kg,2例为急性A型主动脉夹层,2例为冠心病,1例为感染性心内膜炎合并白塞氏病,患者确诊后出现创面感染重、分泌物多,行VSD(负压封闭引流)进行过渡治疗,待创面清洁、肉芽新鲜后入手术室行清创术,术中4例采用SternaLock胸骨固定系统进行固定,1例因未累及至胸骨后,仅在胸骨前方行清创缝合。结果4例完全治愈并顺利出院,1例因出现多器官功能衰竭死亡,但伤口愈合良好。结论通过VSD引流增加了胸骨血流,加速肉芽组织形成,防止感染进一步加重,稳定胸骨,为进一步清创创造了良好的基础,同时运用SternaLock■胸骨固定系统(8孔型钛板及2.4 mm自钻锁螺钉)进行固定,明显增加了胸骨的稳定性,进一步改善患者预后。Objective To summarize the application experience of a new technique in mediastinal infection after cardiac operation.Methods A retrospective analysis of adult patients with mediastinal infection after cardiac surgery from February 2017 to June 15,2019 were taken including a total of 5 cases(1.2%),of which 4 were male and 1 was female,with an average age(49±19)years old,average weight(70±15)kg;2 cases had acute type A aortic dissection,2 cases had coronary heart disease,1 case had infective endocarditis with Behcet's disease.After diagnosed,the patients developed severe wound infection and excessive secretion.VSD(vacuum sealing drainage)was performed for transitional treatment.After the wounds were cleaned and the granulation were still fresh,the wounds were for debridement in the operating room.During the operation,4 cases were fixed with the SternaLock■ plating system,and 1 case was only treated with debridement and suture in front of the sternum because it did not involve the sternum.Results Four cases were cured and discharged smoothly,and 1 case died due to multiple organ failure,but the wound healed well.Conclusion The VSD increased sternum blood flow,which accelerated the granulation tissue formation,further to prevent infection and stable sternum,create a good foundation for further debridement,meanwhile the SternaLock■ plating system(consists of eight pass since the titanium plate and 2.4 mm drill lock screw)was used for fixation,which significantly increased the stability of the sternum,further improved the prognosis of patients.
