目的探讨负压封闭引流术对烧伤患者的安全性及有效性。方法采用随机平行对照法将109例烧伤患者进行分组,对照组54例给予传统换药治疗,观察组55例给予负压封闭引流术治疗。观察并比较两组患者治疗后的临床疗效、创面愈合时间、疼痛程度、植皮生长情况以及并发症发生率。结果观察组优良率为94.55%,高于对照组的77.78%(P<0.05);观察组治疗后视觉模拟评分及创面愈合时间均低于对照组(P<0.05);观察组治疗后植皮成功率(96.36%)、肉芽组织生长良好率(98.18%)、细菌培养阴性率(98.18%)均高于对照组(75.93%、79.63%及77.78%),并发症发生率(5.45%)低于对照组(20.37%,P<0.05)。结论采用负压封闭引流术通过保持创面清洁,抑制细菌的繁殖,减少感染及换药次数,减少烧伤患者创面愈合时间,降低患者疼痛程度,效果确切,安全性高,值得临床推广及应用。
Objective To investigate the safety and effectiveness of negative pressure closed drainage on burn patients. Methods A total of 109 cases of burn patients were divided into two groups according to the randomized parallel control method. 54 cases in the control group were given traditional dressing change, and 55 cases in the observation group were treated by negative pressure closed drainage. The clinical curative effect, wound healing time, pain degree, skin graft growth and complication rate were observed and compared between the two groups. Results The excellent and good rate in the observation group was 94.55%, which was significantly higher than that in the control group (77.78%, P <0.05). The visual analog scale and wound healing time in the observation group were lower than those in the control group (P <0.05) (96.36%), good rate of granulation tissue growth (98.18%) and bacterial culture (98.18%) were higher than that of the control group (75.93%, 79.63% and 77.78% respectively). The complication rate (5.45% Control group (20.37%, P <0.05). Conclusion The negative pressure closed drainage can keep the wound clean, inhibit the multiplication of bacteria, reduce the number of infections and dressing changes, reduce the wound healing time and reduce the degree of pain in patients with burn, the effect is accurate and safe, which is worthy of clinical promotion and application.
