He-Ne激光对甲手术创面愈合促进作用的评价

目的评价He-Ne激光照射对甲手术创面愈合的作用。方法患者由随机数字表分配到对照组和治疗组，每组20例，治疗组在甲手术后使用He-Ne激光照射创面。比较两组患者创面愈合时间、炎症持续时间、疼痛评分、甲板完全生长时间。结果两组患者基线差异无统计学意义。甲手术后创面愈合时间，对照组平均需要(16.00±2.51) d，治疗组则需要(11.35±1.73) d，两者差异有统计学意义（P<0.05）。甲手术后炎症消退的时间为：对照组(9.10±2.10) d，治疗组(7.20±1.44) d，两者差异有统计学意义（P<0.05）。甲手术后，甲板完全生长需要的时间，对照组（21.00±2.13）周，治疗组（21.40±1.05）周（P>0.05）。在甲手术后治疗组照射第3次（25 h）后，疼痛评分与对照组比较差异有统计学意义（P<0.05）。5次照射（49 h）后治疗组疼痛消失的患者达到85.0%（17/20），而6次治疗（54 h）后，该组患者疼痛全部消失，皆快于对照组（分别为50.0%和98.5%）。结论He-Ne激光照射可以促进甲手术后创面恢复，减轻患者痛苦。

英文摘要:

Objective To investigate the effect of He-Ne laser therapy on wound healing after nail surgery. Methods Patients who needed nail surgery were divided into treatment group (n=20) and control group (n=20) randomly.The He-Ne laser was applied to the wound after nail surgery in treatment group. The wound healing time, the inflammation duration, the pain rating, and the nail plate full-grown time were compared with control group. Results No significant differences in baseline of two groups were observed. The wound healing time was (16.00±2.51) d in control group and (11.35±1.73 ) d in treatment group,the inflammation duration was (9.10±2.10) d in control group and (7.20±1.44) d in treatment group (P<0.05), both above differences were significant (P<0.05).The nail plate full-grown time was (21.00±2.13) weeks in treatment group, whereas (21.40±1.05) weeks in control group (P＞0.05).The pain rating of the 2 groups was different from 25 h (after 3 times treatment)(P<0.05). Pain disappeared in 85.0% (17/20) patients of treatment group after 49 h (5 times treatment), and completely disappeared (20/20) after 54 h (6 times treatment),which were faster than those of control group at the same time points (pain disappeared only in 50.0% and 98.5% of patients respectively). Conclusion He-Ne laser therapy can help wound healing after nail surgery.
