过氧化氢低温等离子灭菌与传统灭菌效果方法比较

目的 探讨硬式腔镜器械经过氧化氢低温等离子灭菌的效果及与传统灭菌效果的差异。方法 选取2017年8月~2018年6月我院供应手术的腔镜器械60套，采用随机数字表法分为两组，各30套。对照组采用传统的脉动真空压力灭菌法，观察组采用过氧化氢低温等离子体灭菌法，观察过氧化氢低温等离子体灭菌的效果监测情况，比较两种灭菌法的细菌残留率、器械损伤情况、医护人员的不良反应、消毒时间及灭菌后保存的有效时间。结果 观察组化学监测时1例不合格，合格率为96.67%，生物监测和物理监测合格率为100.00%；观察组的细菌残留率为3.33%，低于对照组的26.67%，差异具有统计学意义（P＜0.05）；观察组灭菌时间长于对照组，灭菌后保存的有效时间长于对照组，差异均有统计学意义（P＜0.05）；观察组未发生器械损伤情况和医护人员的不良反应，与对照组比较，差异有统计学意义（P＜0.05）。结论 硬式腔镜器械经过氧化氢低温等离子灭菌安全有效，与传统灭菌方法相比，灭菌后的细菌残留率更低，灭菌后的保存有效时间更长，对器械损伤情况和医护人员无不良反应，优势显著。

Comparison of Low Temperature Plasma Sterilization with Hydrogen Peroxide and Traditional Sterilization Methods

Objective To investigate the effect of low-temperature plasma sterilization of hard endoscopic instruments with hydrogen oxide and the differences from traditional sterilization methods. Methods 60 laparoscopic instruments supplied from August 2017 to June 2018 in our hospital were divided into two groups by random number table method, with 30 sets in each group. The control group used the traditional pulsed vacuum pressure sterilization method, and the observation group used the hydrogen peroxide low temperature plasma sterilization method to observe the effect of hydrogen peroxide low temperature plasma sterilization. Damage to equipment, adverse reactions of medical staff, disinfection time and effective storage time after sterilization. Results 1 case failed the chemical monitoring in the observation group, with a pass rate of 96.67% and a pass rate of 100.00% in the biological and physical monitoring; the bacterial residual rate in the observation group was 3.33%, which was lower than 26.67% in the control group,the difference was statistically significant(P<0.05); the sterilization time in the observation group was longer than that in the control group, and the effective storage time after sterilization was longer than that in the control group,the differences were statistically significant (P<0.05); the observation group did not have equipment damage and no medical staff response, compared with the control group,the difference was statistically significant (P<0.05).Conclusion The rigid endoscopic instruments are safe and effective after low-temperature plasma sterilization with hydrogen oxide. Compared with traditional sterilization methods, the residual rate of bacteria after sterilization is lower, and the effective storage time after sterilization is longer. There are no adverse reactions in personnel, and the advantages are significant.
