Abstract:
Objective To study the effectiveness of alkaline electrolyzed water (AEW)in the cleaning of medical instruments and its corrosive effect on metal. Methods Medical instruments of solid smooth,solid with gear or tube were cleaned with AEW adding ultrasonic washing,cleaning efficacy were compared with conventional method, AEW without pulsing ultrasonic washing and control group,corrosive effect of AEW on metal immersed in AEW was tested. Results Cleaning efficacy of solid smooth,solid with gear or tube instruments were significantly differ-ent among four groups(F= 10.868,14.268,6.146,respectively,all P<0.05). For solid smooth instruments, cleaning with AEW adding ultrasonic and cleaning without ultrasonic had a better effect than conventional cleaning (both P<0.005);For solid with gear instruments,AEW adding ultrasonic cleaning obviously had a better effect than conventional cleaning and AEW without ultrasonic cleaning(both P<0.001 );For tube instruments,cleaning efficacy of three cleaning methods were not significantly different (all P>0.05). AEW had no corrosive effect on stainless steel and copper. Conclusion The cleaning efficacy of AEW on solid smooth,solid with gear instruments is su-perior to conventional cleaning method,and can achieve better effectiveness if ultrasonic cleaning is added.
