Study on ATP bioluminescence in assaying the cleaning quality of uterine suction / 中国基层医药

ABSTRACT

Objective To explore the application value of ATP bioluminescence in assaying the cleaning quality of uterine suction.Methods According to the principle of random,we selected 120 uterine suction tube after use.60 used tubes in A group were given water immersion + high-pressure water jets wash + dry method,60 used tubes in B group were given alkaline cleaning solution soak + ultrasonic + high-pressure water washing + manual scrub + drying method.The quality of suction tube was initially tested with the visual method after cleaning,Straw inside the top cavity,2.5cm at inside straw joint and the front of straw outer wall,10cm at suction cavity wall,before and after cleaning the residues of bacteria were assayed with the ATP bioluminescence and bacteria counting method for parallel comparison.Results After cleaning drying program,the RLU of two groups in suction head internal top,2.5cm at inside straw joint,the front of straw outer wall,10cm at suction cavity wall had significant differences (t =26.81,29.13,7.14,55.74,P ＜ 0.01).The cleaning effect of B group was better than A group..Bacteria counting method was used to detect pathogenic microorganism that was not detected.The qualified rate of cleaning at four parts was as followinggroup A70.0％,85.0％,93.3％,93.3％.B group95.0％,98.3％,100.0％,100.0％,and the qualified rate of group B was significantly higher than group A (x2 =12.99,6.98,4.14,4.14,all P ＜ 0.05).Conclusion ATP bioluminescence method can dynamically rapid detect the bacteria before and after intrauterine suction cleaning residues,can be viewed as an effective method to detect quality of uterine suction cleaning.
