Objective To investigate the causes of the vacuum seal ing drainage (VSD) compl ications during treatment of extremity wounds. Methods Between February 2005 and February 2010, 174 patients with skin and soft tissue defect of extremities were treated with VSD. Among them, 12 patients (6.9%) had compl ications and the cl inical data were analyzed retrospectively. There were 7 males and 5 females aged from 17 to 65 years (mean, 36.1 years). Injury was caused bytraffic accident in 8 cases, and by machine extrusion in 4 cases. The locations were forearm in 3 cases, upper arm in 2 cases, thigh and calf in 1 case, calf in 4 cases, and foot in 2 cases. The size of defect ranged from 10 cm × 7 cm to 90 cm × 40 cm. The time from injury to hospital ization was 3-8 hours (mean, 4.2 hours). Results At 1 day postoperatively, moderate to severe anemia and hypokalemia occurred in 6 cases, and the hemoglobin value increased to 100 g/L and the electrolyte disorder was rectified after blood transfusion and fluid infusion. At 2 days, 2 patients had local skin allergic symptoms, and local rash disappeared after oral administration of Clarityne. At 3 days, 2 patients complained pain and the pain was released after the suction pressure was decreased by 50%; 2 patients had infection and received VSD demol ition, debridement and draining, and anti-infection treatment. Tissue necrosis occurred in 1 case at 4 days and pressure ulcer in 1 case at 5 days, VSD was immediately changed and wound was repaired by spl it thickness skin graft or local flap. Conclusion Compl ications associated with VSD therapy for the wounds of the extremities are not very common. Most causes are related to the location of wound, the technique of the operators, and the conditions of the patients.
目的 探讨可调压胸腔闭式引流瓶持续负压吸引治疗自发性气胸持续漏气的疗效观察及护理。 方法 将2008年3月－2012年10月收治的自发性气胸行胸腔闭式引流术后接传统闭式引流瓶，引流达3 d胸腔仍有漏气患者55例分为A组（治疗组）、B组（对比组）。Ａ组30例更换为可调压胸腔闭式引流瓶、Ｂ组25例继续使用传统闭式引流瓶。 结果 Ａ组患者平均带管时间缩短，管腔堵塞、引流液逆流、低蛋白血症等并发症发生比Ｂ组减少。 结论 可调压胸腔闭式引流瓶持续胸腔负压吸引治疗自发性气胸持续漏气患者治疗效果优于传统闭式引流好，患者带管时间及平均住院时间缩短，住院费用降低，安全性高，并发症少。
