Bactericidal Effect of Electrolyzed Oxidizing Water on Deep Second-degree Burn Wounds and Infected Surface Wounds

Objective To investigate the bactericidal effect of electrolyzed oxidizing water(EOW) on deep second-degree burn wounds and infected surface wounds.Methods EOW was used for wound irrigation in 20 patients with deep second-degree burn wounds(group A) and 20 patients with burn wound infections(group B).The same type of wounds were irrigated with normal saline on the relative parts in group A(control group 1) and group B(control group 2),respectively.Wound smears were obtained before(T0) and 1(T1),4(T4) and 7(T7) days after wound treatment.Specimens were sampled using cotton tipped swabs and bacteria were cultured at 37 ℃ for 48 hours.The number of colonies was counted and the decrease in the number of colonies after treatment was compared.Results The number of colonies significantly reduced in all groups after treatment and the difference of the number of colonies increased with treatment duration(P 0.01).Compared with control group 1 and 2,the magnitude of reduction in the number of colonies significantly increased in group A and B,respectively(P0.01).Conclusion EOW exerts a better bactericidal effect on deep second-degree burn wounds and infected surface wounds than normal saline.
