一次性切口牵开固定器在大腿吸脂手术中的应用

Application of disposable incision retractor fixator in thigh liposuction

目的探讨一次性切口牵开固定器应用于大腿吸脂手术对降低术后并发症发生率的效果。方法选择硬膜外麻醉下行大腿吸脂手术的患者50例,将同一患者左右大腿切口随机分配到Ⅰ或Ⅱ组(即将同一患者的双侧大腿分入不同组),Ⅰ组实施常规吸脂术、不使用固定器,Ⅱ组加用一次性切口牵开固定器。观察术中、术后患者生命体征,记录手术时间、出血量、拆线时间,以及术后切口红肿、感染、切口愈合情况、明显色素沉着等。结果Ⅰ组术后切口红肿、感染百分率比Ⅱ组高,比较差异均有统计学意义(P均<0.05);Ⅰ组术后拆线时间较Ⅱ组长,不良切口愈合(Ⅱ期、Ⅲ期)以及切口明显色素沉着百分率较Ⅱ组多,比较差异均有统计学意义(P均<0.05)。结论采用一次性切口牵开固定器进行大腿吸脂手术可降低该类手术术后并发症的发生率。

Objective To evaluate the effect of the disposable incision retractor fixator upon reducing the incidence of complication after thigh liposuction surgery. Methods Fifty patients scheduled to undergo thigh liposuction under epidural anesthesia were recruited in this investigation. For each patient, bilateral thigh incisions were randomly divided into two groups. In group Ⅰ, conventional liposuction alone was performed. In group Ⅱ, the disposable incision retractor fixator was supplemented. Intraoperative and postoperative physical signs were observed. The operation time, bleeding volume, time of stitch removal, postoperative incision swelling, infection, wound healing and evident wound pigmentation were recorded. Results The percentage of postoperative incision swelling and infection in group Ⅰ was significantly higher compared with that in group Ⅱ （both P 〈 0.05）. The time of stitch removal in group Ⅰ was significantly longer than that in group Ⅱ （P 〈 0.05）. In group Ⅰ, the percentage of poor wound healing （Ⅱ and Ⅲ stage） and evident wound pigmentation was significantly higher compared with that in group Ⅱ （both P 〈 0.05）. Conclusion Application of the disposable incision retractor fixator can reduce the risk of postoperative complications after thigh liposuction.
