Objective To investigate the curative effect of facility negative pressure closed drainage on wounds in earthquake. Methods We retrospectively analyzed the data of 35 patients treated by facility negative pressure closed drainage after debridement in earthquake. The same category patients treated by conventional therapy as the control group. Results Time of facility negative pressure closed drainage was 6-12 days, average 7.5±1.8 days. The woundswere all cured. The wounds closure were performed with skin grafting in 24, with secondary suturing in 4, with regionalflap transposition in 5, and with cross leg flap in 2. There were significant differences in time of secondary closure, timesof dressing and the total time of hospitalization between two groups (Plt;0.01). And there was a significant difference incurative effect of skin grafting between two groups (Plt;0.05). Conclusion Facility negative pressure closed drainage on treating wounds in earthquake is a simple, safe method, and has significant curative effect.
目的 观察可调节负压引流技术联合局部氧疗治疗腹部切口感染创面的临床效果。 方法 对2009年5月－2012年9月28例腹部切口感染创面患者使用可调节负压引流技术联合局部氧疗治疗，创口内填入负压吸附垫，持续输氧0.5～1 L/min，可调节负压采用连续工作模式，使密闭创面保持60～120 mm Hg（1 mm Hg=0.133 kPa）的负压状态，3～7 d更换负压吸附垫和引流管。 结果 28例切口创面感染得到控制。8例经一次治疗创面愈合，15例经2～4次治疗创面愈合，2例行Ⅱ期缝合，3例患者对贴膜过敏，治疗一次后改为换药治疗。28例患者创面愈合时间4～28 d，平均14 d，随访1～18个月无切口裂开，7例有凹陷瘢痕，余瘢痕平整。 结论 可调节负压引流技术联合局部氧疗治疗腹部切口感染创面，具有操作简便、安全可靠、疗效明显的优点，可加快创面愈合，缩短住院时间，提高切口的愈合质量，减轻患者痛苦及医务人员的工作量。
