He-Ne激光对愈合延迟创面修复的促进作用

目的 :观察He -Ne激光对整形手术愈合延迟创面的修复作用及可能发生的不良反应。方法 :选择整形术后创面愈合延迟患者 42例为受试对象 ,A组 ( 2 2例 )为治疗组 ,用He -Ne激光照射联合常规换药方法处理 ,B组 ( 2 0例 )为对照组 ,单纯采用常规换药方法处理 (观察激光对坏死或感染创面有无促进愈合作用及是否可减少再手术植皮率 ,并观察其不良反应 )。结果 :A组患者创面 3周内愈合率为 86 .82 % ,B组患者创面 3周内愈合率为 5 5 % ;A组患者再手术植皮率明显低于B组。 (P <0 .0 5 )A组创面分泌物及创周炎明显轻于B组 ;两组患者创面均未发现明显不良反应。结论 :He -Ne激光可促进整形术后愈合延迟创面愈合 ,缩短愈合时间 ,减少再手术植皮率 ,无明显不良反应

Promoting effect of He-Ne laser on repair of intractable wounds

Objective:To observe the repairing effects and adverse action of He-Ne Laser on intractable wounds after plastic operations.Methods:The 42 patients with intractable wounds after plastic operations are randomly divided into trial group (A)and control group(B).In trial group(n=22),the wounds are applied with He-Ne Laser while in control group(n=20),the wounds with the saline gauze dressings to observe whether He-Ne Laser in low intensity can promote healing of wounds with necrotic or infectious,reduce the rate of re-grafting skin and induce adverse reactions.Results:The rate of wound healing in 3 weeks is 86.82% in the trail group and is 55% in the control group.In comparison with control group,exudate and local inflammation are slighter on the trial group wounds.Conclusion:He-Ne Laser can promote the healing of intractable wounds,shorten the healing time and decrease the rate of re-grafting of skin.He-Ne Laser is convenient,safe,non-irritative and has no marked adverse actions.
