Effects of red light irradiation on blood phosphorus in maintenance hemodialysis patients / 国际生物医学工程杂志

ABSTRACT

Objective To evaluate the effect of red light irradiation on serum phosphorus reduction in hemodialysis.Methods Sixty maintenance hemodialysis patients were divided into treatment group and control group.During the hemodialysis,the blood in the extracorporeal circulation tube of the patents in the treatment group was irradiated with red light by a MRX-1 red light therapy system.The irradiation was continued for 60 minutes each time,and one course of the treatment contained 10 times of irradiations.Patients in the control group were subjected to hemodialysis by conventional methods.The serum phosphate levels of all patients were measured before and after the treatment.Results The symptoms of dialysis disequilibrium of the patients in the treatment group were alleviated.There was no significant difference in serum phosphate levels between the treatment group and the control group before hemodialysis,while a statistically significant difference was found after the treatment (P＜0.05).Conclusions Hemodialysis combined with red light irradiation on external blood trails can contribute to the decrease of serum phosphate levels in maintenance hemodialysis patients.
