Class iv Versus Class Iiib Laser Therapy on Median Sternotomy Healing After Coronary Artery Bypass Graft: a Randomize Control Trail

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.

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.

group A receive laser therapy class IV+traditional wound care and group (B): Laser therapy class IIIb + traditional wound care and group C receive only traditional wound care

he patientsdidnt know the different types of laser which procedure they received & the outcomes assessor done by my supervisors and didn't know which result related to specific group

start from day one surgery for 4 successive weeks, the goal in the phase I (1st 10 days after surgery) is decontamination, improve circulation, pain reduction &wound healing acceleration The goal of phase II (next10 days till complete healing) is improve osteo-integration, pain reduction & enhance superficial collagen production to decrease scarring. The parameters are: Power > 500 mW; fluence 20 joule/ cm2 with (980, 915, 810 nm) and 5 joules/ cm2 by 650 nm; mode (continuous); hand piece radius = 2.5 cm; spot size (Area) = 5 cm; application by scanning not spotting to avoid thermal effect and time of session is 5- 10 minutes

Use the same protocol as in HLLT with the same wave lengths but with low power Power = 200- 300 mW; fluence 20 joule/ cm2 with (980, 915, 810 nm) and 5 joules/ cm2 by 650 nm; mode (continuous); hand piece radius = 2.5 cm; spot size (Area) = 5 cm; application by spotting and time of session was 25- 30 minutes.

According to the hospital protocol Irrigation of the wound by normal saline, betadine application, bivatracin spray and Change dressing daily to protect the wound from infection
