低能量氦-氖激光血管内照射治疗皮肤撕脱伤疗效观察

目的 探讨低能量氦（Ｈｅ）－氖（Ｎｅ）激光血管内照射对撕脱皮瓣原位回植术后皮瓣成活的影响，方法 选择伤后６小时内行清创、撕脱瓣原位回植术撕脱伤患者５８例，其中治疗组３１例应用能量Ｈｅ－Ｎｅ激光血管内照射加常规治疗；对照组２７例仅用常规治疗。结果 术后１５天治疗组撕脱瓣的成活面积、成活质量均明显优于对照组（Ｐ〈０．０５），治疗组血液流变学参数变化在术后５天内最明显。结论 低能量Ｈｅ－Ｎｅ激光血管内照

EFFECT OF INTRAVASCULAR LOW LEVEL LASER IRRADIATION USED IN AVULSION INJURY

Objective To explore the effect of intravascular low level He Ne laser irradiation on skin flap survival after orthotopic transplantation in avulsion injury. Methods Fifty eight cases suffered avulsion injury were treated by debridement and orthotopic transplantation of avulsed flap within 6 hours, 31 of them were received intravascular low level He Ne laser irradiation and routine treatment, and 27 of them were received routine treatment as control group. Results\ The survival area and quality of avulsed flap in the experimental group were superior to that of control group after 15 days of operation, and the hemorheological items were markedly changed at 5 days after operation. Conclusion The better flap survival after orthotopic transplantation in avulsion injury can be improved by intravascular low level He Ne laser irradiation through changed superoxide dismutase activity and hemorheological items in optimal irradiation intensity.
