The aim of this study was to investigate the effects of class IV high-level laser therapy (HLLT) versus class IIIb low level laser therapy (LLLT) on sternotomy healing following coronary artery bypass grafting (CABG) surgery. Forty- five patients male patients who had CABG surgery in the age range of 45-65 years were divided randomly into three equal groups (n = 15). The group HLLT laser received HLLT plus traditional wound management, while the group LLLT laser received LLLT plus traditional wound management. The control group only received a traditional wound management in form of saline irrigation, dressing, and topical bivatracin spray according to hospital protocol. All groups were offered 10 sessions over 4 weeks. HLLT and LLLT were found to be the most effective methods for sternotomy healing post-CABG surgery, with HLLT offering superior performance in the case of the high deep penetration and significance less time needed to deliver the same joules/ cm compared to LLLT used for the wound site.
LASER therapy is potent physiotherapy modalities, providing better sternotomy healing for patients who have undergone CABG surgery, compared with traditional wound care management alone. HLLT and LLLT were found to be the most effective methods for sternotomy healing post-CABG surgery, with HLLT offering superior performance in the case of the high deep penetration and significance less time needed to deliver the same joules/ cm compared to LLLT used for the wound site.
