BACKGROUND
The aim of this study was to evaluate the efficacy of low-level laser therapy for reducing the acute pain of sternotomy in patients who underwent a coronary artery bypass graft (CABG).
METHODS
This study was conducted with ninety volunteers who electively submitted to CABG. The volunteers were randomly allocated into three groups of equal size (n = 30): control, placebo, and laser (λ of 660 nm and spatial average energy fluency of 1.06 J/cm 2 ). Pain when coughing was assessed by a visual analog scale (VAS) and McGill Pain Questionnaire, according to sensory, affective, evaluative, and miscellaneous domains. The patients were followed for 1 month after the surgery.
RESULTS
The laser group had a greater decrease in pain with analogous results, as indicated by both the VAS and the McGill questionnaire (P ≤ 0.05) on sensory and affective scores, on days 6 and 8 postsurgery compared to the placebo and control groups.
CONCLUSION
Laser seems to be effective promoting pain reduction after coronary-arterial bypass grafting.
背景
本研究旨在评估低强度激光疗法对接受冠状动脉旁路移植术（CABG）患者胸骨切开术后急性疼痛的缓解效果。
方法
本研究纳入了90名择期接受CABG的志愿者。志愿者被随机分为三组，每组人数相等（n = 30）：对照组、安慰剂组和激光组（波长660 nm，空间平均能量通量为1.06 J/cm²）。根据感觉、情感、评估和其他方面，通过视觉模拟量表（VAS）和麦吉尔疼痛问卷评估咳嗽时的疼痛。术后对患者进行1个月的随访。
结果
与安慰剂组和对照组相比，激光组在术后第6天和第8天的感觉和情感评分方面，VAS和麦吉尔问卷均显示疼痛有更大程度的减轻（P≤0.05）。
结论
激光似乎对冠状动脉旁路移植术后减轻疼痛有效。
