低能量氦-氖激光血管内照射治疗皮肤撕脱伤疗效观察

EFFECT OF INTRAVASCULAR LOW LEVEL LASER IRRADIATION USED IN AVULSION INJURY

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、撕脱瓣原位回植术后撕脱伤患者58 例,其中治疗组31 例应用低能量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 激光血管内照射的生物学效应存在最佳的照射强度总量,在最佳的照射强度条件下。

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.
