Investigation on cleaning of silicone oil attached ophthalmic surgical instruments in 22 provinces (regions,municipality) in China / 中国实用护理杂志

ABSTRACT

Objective:To investigate the cleaning status of silicone oil attached ophthalmic surgical instruments in China, so as to provide reference and suggestions for the standard cleaning process of silicone oil attached ophthalmic surgical instruments.Methods:61 hospitals in 22 provinces (regions, municipality) in China were selected as the objects of investigation. The on-site treatment, pretreatment and routine cleaning of silicone oil attached ophthalmic surgical instruments were investigated by questionnaire from November 2019 to January 2020.Results:18.033% (11/61) hospitals had mixed silicone oil attached ophthalmic surgical instruments and other instruments intraoperatively, 11.475% (7/61) hospitals didn′t wipe silicone oil and other visible contaminants postoperatively. 18.033% (11/61) hospitals didn′t carry out pretreatment and 4.000% (2/50) hospitals used saline as pretreatment solution; 54.098% (33/61) hospitals were involved in ultrasonic cleaning. 32.787% (20/61) hospitals had water temperature 31-37 ℃ and 4.918% (3/61) hospitals had water temperature>37 ℃during the cleaning process; During pretreatment and routine cleaning, 38.000% (19/50) hospitals and 54.902% (28/51) hospitals selected enzymatic detergent respectively, the contact time between instruments and detergent in specialized hospital was more standardized than that in general hospital ( P<0.001); In flushing, rinsing and final rinsing, there were 29.412% (15/51) hospitals, 11.765% (6/51) hospitals and 3.922% (2/51) hospitals used water that didn′t meet the requirements. 17.647% (9/51) hospitals, 13.725% (7/51) hospitals and 13.725% (7/51) hospitals didn′t record the time of flushing, rinsing and final rinsing. Conclusions:There are still some problems in the cleaning of silicone oil attached ophthalmic surgical instruments in specialized and general hospitals, such as no on-site treatment and pretreatment, improper control of cleaning parameters, and difficulty in ensuring water quality and water time. It is necessary to formulate the cleaning process specification of silicone oil attached ophthalmic surgical instruments as soon as possible to ensure the cleaning quality and avoid the occurrence of postoperative eye complications.
