OBJECTIVE: Determine the optimal number of suction drains in abdominoplasty procedures.
METHODS: Retrospective cohort study, analyzing all abdominoplasty patients operated by a single surgeon. Patients were stratified into 3 groups based on number of drains inserted at the end of the procedure. Rate of complications was compared between the groups and a multivariate logistic regression model was computed for the development of complications.
RESULTS: Seven-hundred and forty three patients were included in the analysis of this study. No drains were inserted in 355 patients (45%), whereas a single drain was inserted in 153 (20.6%) 2 drains in 255 patients (34.4%). Patients for whom a single drain was inserted intra-operatively, experienced at a statistically significant lower rate, surgical site infections (OR = 0.235), hypertrophic scars (OR = 0.326), wound dehiscence (OR = 0.272), as compared to patients with no drains. On the contrary, insertion of single drain was associated with a statistically significant higher risk for development of seroma (OR = 6.276) and the need for revision surgery (OR = 2.452).
CONCLUSIONS: Insertion of a single drain is associated with a lower risk of SSI and wound- dehiscence, but a greater risk for seroma development that requires surgical intervention.

目的:确定腹壁成形术中最佳的抽吸引流管数量。
方法:回顾性队列研究,分析由一名外科医生操作的所有腹部成形术患者。根据手术结束时插入的排水管数,将患者分为3组。比较两组之间的并发症发生率,并计算多变量逻辑回归模型以评估并发症的发展。
结果:七百四十三名患者被纳入本研究的分析。355例患者(45%)未插入引流管,而在255例患者(34.4%)的153例(20.6%)中插入了单个引流管2个引流管。术中插入单个引流管的患者,经历了统计学上显著的较低比率,手术部位感染(OR=0.235),增生性疤痕(OR=0.326),伤口裂开(OR=0.272),与没有排水沟的患者相比。相反,单一引流管的插入与血清肿(OR=6.276)和需要翻修手术(OR=2.452)的发生具有统计学意义的较高风险相关.
结论:插入单个引流管与较低的SSI和裂开风险相关,但血清肿发展的风险更大,需要手术干预。
方法:本期刊要求作者为每篇文章分配一定程度的证据。对于这些循证医学评级的完整描述,请参阅目录或在线作者说明www。springer.com/00266.
