【目的】探讨持续性负压引流与间歇式负压引流对骨科难愈创面的临床治疗效果。【方法】选取2012年5月至2015年5月本院骨科58例创面难愈合的患者。随机分为对照组和试验组。对照组采用持续性负压引流治疗,试验组采用间歇式负压引流治疗。对比分析两组患者出现新肉芽组织的时间、创面总愈合时间、标准化创面愈合时间、创面感染控制时间和 d12创面病原菌培养情况。【结果】试验组出现新肉芽组织的时间、创面总愈合时间、标准化创面愈合时间和创面感染控制时间均小于对照组,d12创面病原菌培养阳性率低于对照组(P <0.05)。【结论】骨科难愈创面的治疗中采用间歇式负压引流可明显缩短治疗时间,有效控制感染,促进创面肉芽组织生长和伤口愈合。“,”Objective]To investigate the clinical effect of continuous negative pressure drainage and inter-mittent negative pressure drainage in orthopaedic refractory wounds.[Methods]From May 201 5 to May 2012, 58 cases of refractory wound in the Department of orthopedics in our hospital were selected and randomly di-vided into control group and experimental group.The control group was treated with continuous negative pres-sure drainage,and the experimental group was treated with intermittent negative pressure drainage.The two groups of patients were compared with new granulation tissue,wound healing time,wound infection control time and d12 wound pathogen culture.[Results]The time of new granulation tissue,the time of wound heal-ing,the healing time of wound and the control time of wound infection in the experimental group were all low-er than those in the control group.The positive rate of D12 was lower than that of the control group (P <0.05 ).[Conclusion]Intermittent negative pressure drainage in Orthopedics chronic wound treatment can signifi-cantly shorten the treatment time,effectively control infection and promote growth of granulation tissue and wound healing.
