- 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 hours,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(OR>1,P<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(OR<1,P<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 clean-ing 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.
