摘要

目的

探讨夜间急诊腹腔镜手术器械的超声波清洗效果及影响因素。

方法

选取超声波清洗的698次夜间急诊腹腔镜手术器械作为研究对象，统计其超声波清洗质量不合格情况，对可能导致超声波清洗质量不合格的因素进行单因素和多因素二元

Logistic

回归方程分析。

结果

夜间急诊腹腔镜手术器械的698次超声波清洗中，共有55次（7.88%）清洗质量不合格。单因素及多因素二元

Logistic

回归分析结果显示，清洗时距手术结束时间≥10 h、管腔类手术器械、预处理不规范、清洗水质不合格和清洗介质不合格是导致夜间急诊腹腔镜手术器械超声波清洗质量不合格发生的危险因素(

1，

0.05)，而手工+超声波清洗为避免夜间急诊腹腔镜手术器械超声波清洗质量不合格发生的保护性因素(

1，

0.05)。

结论

夜间急诊腹腔镜手术器械的超声波清洗质量不合格率较高，在手术结束后应尽早对其进行清洗，在超声波清洗前，尽量先进行手工清洗，尤其对于难清洗的管腔类手术器械，还应进行规范的预处理、选择合格的清洗水质和介质。

Abstract

Objective

To explore the ultrasonic cleaning effect and influencing factors of emergency laparoscopic surgical instruments at night.

Methods

A total of 698 emergency laparoscopic surgical instruments cleaned by ultrasound at night were selected as the research subjects，and the unqualified ultrasonic cleaning of instruments was statistically analyzed. Univariate and multivariate binary

Logistic

regression equations were used to analyze the factors that may lead to unqualified ultrasonic cleaning.

Results

Among 698 ultrasonic cleaning sessions for emergency laparoscopic surgical instruments at night，a total of 55 times （7.88%） were unqualified. The results of univariate and multivariate binary

Logistic

regression analysis showed that the time from cleaning to the end of surgery ≥10 hou

rs，luminal surgical instruments，nonstandard pretreatment，unqualified cleaning water quality，and unqualified cleaning medium were the risk factors that lead to the occurrence of unqualified ultrasonic cleaning of emergency laparoscopic surgical instruments at night （

1，

0.05），while manual+ultrasonic cleaning was the protective factor to avoid the occurrence of unqualified ultrasonic cleaning of emergency laparoscopic surgical instruments at night （

1，

0.05）.

Conclusion

The unqualified rate of ultrasonic cleaning of emergency laparoscopic surgical instruments at night is relatively high，so it should be cleaned as early as possible after the surgery. Before ultrasonic cleaning，manual cleaning should be carried out as much as possible，especially for luminal surgical instruments that are difficult to clean，standardized pretreatment should be carried out，and qualified cleaning water quality and medium should be selected.
