Effect of laser puncture on liver enzymes post burn

Abstract

Objective. The present study was carried out to investigate the impact of laser puncture as an adjunctive therapy on liver enzymes after a burn. Material and Methods: The study included 30 injured patients with burned body surface areas ranging from 30 to 50%. They were aged from 25 to 40 years. Cases from Orabi Hospital were randomized into two groups, equal in number. Group A included 15 cases as they received laser acupuncture (infrared diode laser, wavelength 808 nanometers, with pulse interval: 200 nanoseconds, power density: 0.4 Watt/cm², and energy density 4 Joule/cm²); it was located in direct connection with skin perpendicular to the body acupoints (ST36), (SP6), (LR3), (GB34), (BL18) on each side of the body as well as Zhongwan (RN12) and conducted for 90 seconds for every point three times a week, for 4 weeks after leaving the intensive care unit, conventional physiotherapy program as well as medical treatment. Group B included 15 patients as they received only their conventional physiotherapy program as well as medical treatment. Aspartate transaminase (AST) and liver enzymes, alanine transaminase (ALT) were determined using a spectrophotometer. Results. After four weeks of our intervention, it was found that the laser puncture group had significantly lower ratios of plasma liver enzymes than those in the control group. Thus, it can be concluded that laser puncture serves as an efficient adjunctive therapy for improving liver function after a burn.
