软式消化内窥镜改良生物荧光法非常规监测点清洗质量检测研究
Study on positive detection of cleaning quality of unconventional monitoring points by bioluminescence method in flexible digestive tract endoscopes
摘要
Abstract
Objective:To comprehensively improve the positive detection rate of digestive tract endoscopes cleaning quality by increasing the number of unconventional monitoring points for digestive tract endoscopes.Methods:A total of 160 ordinary flexible digestive tract endoscopes used for clinical examination in the Endoscopy Center of Zhongshan Hospital Fudan University from September to November 2022 were selected,and the cleaning quality of the digestive tract endoscopes was tested by traditional adenosine triphosphate(ATP)detection method and modified ATP detection method,which were used by random sampling method,with 80 endoscopes for each detection method.In the traditional ATP detection method,an ATP surface test rod was used to sample the outer surface of the endoscope tip at 20 cm and 40 ml of sterile water injected into the inner cavity of the pliers pipe was collected from the tip of the endoscope using an ATP water quality test rod.The modified ATP detection method was based on the traditional ATP detection method,an unconventional monitoring point was added to the inner surface of the forceps pipe outlet,and a sterile sampling swab was used to detect the inner surface of the tube outlet 5 cm away from the outlet of the pipes of the endoscope forceps,and the sample was rotated from the inside to the outside for detection.The cleaning quality of the two testing methods was compared.Results:In cases that the results of the traditional ATP detection method were qualified,the modified ATP detection method found positive substances for the cleaning quality of digestive tract endoscopes at unconventional monitoring points.The unqualified rate of the traditional ATP detection method was 5%(4/80),and the unqualified rate of the modified ATP detection method was 25%(20/80),the difference was statistically significant(x2=12.549,P<0.05).Conclusion:Increasing the unconventional monitoring point at the outlet of the flexible endoscope forceps can significantly increase the detection rate of unqualified endoscope cleaning and improve quality of endoscope cleaning.关键词
