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.

闭合滴注负压引流治疗小儿急性骨髓炎的临床分析

目的:探讨闭合滴注负压引流治疗小儿急性骨髓炎的临床效果。方法:2013年收治小儿急性骨髓炎患者50例,随机分为对照组和观察组,各25例,观察组采用闭合滴注负压引流方法进行治疗,对照组采用传统开窗取出坏死骨组织,并采用大量生理盐水冲洗骨髓腔,待长出肉芽组织后进行植骨。结果:治疗后,观察组的治愈率、总有效率均高于对照组,差异有统计学意义(P<0.05)。在术后3个月和5年分别对患者进行随访,观察组均恢复良好,对照组1例转变为慢性骨髓炎,其余恢复良好。结论:闭合滴注负压引流术在治疗小儿急性骨髓炎方面具有较好的临床效果,并且手术操作简单,抗生素使用时间短,患者治疗费用低,值得在临床中广泛应用。

口服中药托里透脓汤加减联合闭式滴注+负压引流技术VSD治疗难治性褥疮的临床疗效

目的为了进一步促进难治性褥疮的愈合效果,研究和探讨应用口服中药托里透脓汤加减联合闭式滴注+负压引流技术(VSD)的价值和意义。方法根据患者住院号先后顺序从2015年4月~2016年3月期间来我院就诊的难治性褥疮患者中选取24例作为研究对象并通过随机、双盲、对照的原则将其分为试验组和对照组各12例,其中接受传统治疗措施的设为对照组,接受口服中药托里透脓汤加减联合闭式滴注+负压引流技术(VSD)方案治疗的设为试验组,探讨不同治疗方案对两组疗效影响差异。结果研究表明,试验组和对照组都能够获得一定的治疗效果,但和对照组相比试验组患者的褥疮严重程度指数(SSI)评分明显降低,且试验组的清创平均次数、治疗平均时间以及正常体温恢复时间明显减少,两组比较差异具有统计学意义(P<0.05)。结论难治性褥疮患者选取口服中药托里透脓汤加减联合闭式滴注+负压引流技术(VSD)方案治疗,有利于促进褥疮创面愈合,缩短治疗时间和清创次数,减轻患者痛苦,效果显著,值得借鉴推广。
