Value of negative pressure sealing drainage on wound healing of Gustilo IIIB and IIIC open fractures

BACKGROUND Gustilo III fractures have a high incidence and are difficult to treat.Patients often experience difficulty in wound healing.Negative pressure drainage technology can help shorten wound healing time and has positive value in improving patient prognosis.AIM To explore the clinical value of the negative pressure sealing drainage technique in wound healing of Gustilo IIIB and IIIC open fractures.METHODS Eighty patients with Gustilo IIIB and IIIC open fractures with skin and soft tissue injuries who were treated in the Second People’s Hospital of Dalian from March 2019 to December 2021 were selected as the research subjects.They were divided into a study group(n=40,healed with negative pressure closed drainage)and a control group(n=40,healed with conventional dressing changes)according to the variation in the healing they received.The efficacy of the clinical interventions,the variations in the regression indicators(time to wound healing,time to fracture healing,time to hospitalization),and the conversion and healing of bacterial wounds were compared 1-3 mo after the intervention.RESULTS The total effective rate of patients among the study group was 95.00%(38/40),which was notably higher than 75.00%(30/40)among the control group(P<0.05).The wound healing time,fracture healing time,and hospital stay of the patients in the study group was shorter than the control group(P<0.05).After the intervention,the negative bacterial culture at the wound site rate and wound healing rate of the patients among the study group increased compared to the control group(P<0.05).CONCLUSION Negative pressure sealing and drainage technology has a good therapeutic effect on patients with Gustilo IIIB and IIIC open fracture wounds with skin and soft tissue injury.It can notably enhance the wound healing rate and the negative rate of bacteria on the wound surface and help to speed up the recovery process of patients.

皮片原位回植术联合负压封闭引流技术治疗足部皮肤撕脱伤的效果分析

目的:分析用皮片原位回植术联合负压封闭引流技术治疗足部皮肤撕脱伤的临床效果。方法:将近年来云南省曲靖市第二人民医院收治的60例足部皮肤撕脱伤患者随机分为观察组(n=30)与对照组(n=30)。用皮片原位回植术联合负压封闭引流技术对观察组患者进行治疗,用皮片原位回植术联合传统的打包加压技术对对照组患者进行治疗,然后比较两组患者植皮的成活率、进行二次手术的比率、术后并发症的发生率、术后住院的时间及其术后创面愈合的时间。结果:治疗后,观察组患者植皮的成活率高于对照组患者,其进行二次手术的比率和术后并发症的发生率均低于对照组患者,其术后住院的时间和术后创面愈合的时间均短于对照组患者,P<0.05。结论:用皮片原位回植术联合负压封闭引流技术治疗足部皮肤撕脱伤的效果显著,能有效地提高患者植皮的成活率,降低其术后并发症的发生率及进行二次手术的比率,缩短其术后住院的时间及术后创面愈合的时间。
