ABSTRACT

OBJECTIVE To probe cleaning methods of reusable puncture needles and improve the quality of cleaning. METHODS The 200 sets of puncture needles with blood were divided into two groups (groups A and B). Ultrasonic cleaning was used in two groups,but in group A was with 3% hydrogen peroxide solution and in group B with 1∶150 low foam multi-enzyme cleaning liquid for 20 minutes,after rinsing,the group A used 95% ethanol 2 ml/piece for dry,but the Group B used 90 ℃ 30 min,and then the bacterial endo toxins and 3% hydrogen peroxide tests,the cost of cleaning was compared. RESULTS The positive rates of the bacterial endo toxins and 3% hydrogen peroxide test in group A were conducted,at last were 6% and 5%,while group B all were negative (?2=6.19,5.13,P
