Seroma is one of the most troubling complications after abdominoplasty; incidence rates of up to 25% have been reported. If it is correct that shearing forces between the two separated abdominal layers play a key role in the development of seroma, postoperative immobilization of the patient until the layers are sufficiently adhered may be a solution to the problem.
The authors examine the association between length of immobilization and the development of seroma.
This retrospective study included 60 patients; half were immobilized for 24 hours (group 1) and the other half were immobilized for at least 48 hours (group 2). For thromboembolism prophylaxis, all patients received low molecular weight heparin and compression stockings. Postoperative follow-up for detection of seroma continued for at least three months.
Mobilization after 24 hours led to a seroma rate of 13%, whereas immobilization of at least 48 hours decreased the seroma rate to 0%.
For abdominoplasty patients with a low or moderate thromboembolic risk, the data suggest that immobilization for at least 48 hours with chemical and mechanical thromboembolism prophylaxis significantly reduces the risk of seroma.
血清肿是腹部整形术后最令人困扰的并发症之一,其发生率高达 25%。如果说在两个分离的腹部层之间产生的剪切力在血清肿的发展中起着关键作用,那么在层间充分粘连之前对患者进行术后固定可能是解决该问题的一种方法。
作者研究了固定时间长短与血清肿发展之间的关系。
本回顾性研究纳入了 60 例患者;其中一半患者固定 24 小时(1 组),另一半患者固定至少 48 小时(2 组)。为预防血栓栓塞,所有患者均接受低分子肝素和压缩袜治疗。术后至少随访三个月以检测血清肿。
24 小时后开始活动导致血清肿发生率为 13%,而至少固定 48 小时则将血清肿发生率降低至 0%。
对于低危或中危血栓栓塞风险的腹部整形术患者,数据表明,至少固定 48 小时并联合使用化学和机械血栓栓塞预防措施可显著降低血清肿风险。
