Effect of bedside pulse pretreatment on cleaning quality of abortion suc-tion tube
Objective By improving the pretreatment method of abortion suction tube,the influence of pretreatment time and method on the cleaning quality of luminal instruments were explored.Methods A total of 600 abortion suction tubes used in Wuzhou Red Cross Hospital from July 2020 to July 2022 were selected as the study objects and divided into group A(n=200),group B1(n=200)and group B2(n=200)according to the drawing method.The pretreatment of group A was per-formed by pulse flushing the inner wall of the tube with negative pressure suction constant temperature multi-enzyme cleaning agent next to the bed immediately after the abortion suction tube was used.Group B1 and group B2 were pretreat-ed by running underwater flushing the inner wall of the tube immediately after the abortion suction tube was used.After being placed for 3 h,the pre-treated instruments were collected and sent to the supply room for further treatment.Group A were directly put into the ultrasonic cleaning machine for ultrasonic cleaning for 5 min.Group B1 was soaked in multi-en-zyme lotion at room temperature for 20 min,and then washed by ultrasonic cleaning machine for 5 min.Group B2 was soaked in multi-enzyme cleaning agent at normal temperature for 15 min,and then brushed through the tube cavity with a brush for 5 times under the liquid level,and then put into the ultrasonic cleaning machine for ultrasonic cleaning for 5 min.The cleaning quality of three groups of instruments were compared.Results The pass rate of residual protein test,occultary blood test,white strip test and magnifying glass test in group A were higher than those in group B1 and B2,and the differ-ences were statistically significant(P＜0.001).Conclusion To improve the pretreatment method,the site of effective pre-treatment of instruments was moved to the department of use,and the pretreatment time was moved to the immediate post-operative time,which not only practiced the industry standard,but also improved the pretreatment method,seized the best treatment time of contaminated lumen instruments and the strongest effect of enzyme lotion,and used the pulse principle to peel the dirt from the inner wall of lumen to achieve the ideal pretreatment effect,t hus improving the cleaning quality of instruments.
