Abstract Objective To investigate the closure performance and bacteriostasis effect of medical new-type textile and medical ordinary cotton cloth of surgical dressing packs in the sterilization.Methods A total of 240 surgical dressing packs of the same specification in our hospital from July to December 2019 were selected,and divide into experimental group and control group by random drawing method,with 120 cases in each group.In the experimental group,the dressing packages for sterilized surgery were packaged by two layers of medical new-type textile(120 cm×120 cm),while in the control group,the dressing packages for sterilized surgery were packaged by two layers of medical cotton cloth(120 cm×120 cm).After sterilization,when all the surgical dressing packages were qualified in chemical indicator card,chemical indicator tape and physical parameter test,the closure performance of the two groups was compared.All sterilized surgical dressings were stored in the sterile storage area,and bacteriological tests were performed at 7,14,30,60,90 and 180 days after storage,and the positive bacterial cultures of the two groups were compared.Results After sterilization,there was 1 case of loose package in the closure performance test of the experimental group,no wet package or damage,the closure performance qualification rate was 99.17%.In the control group,there were 5 cases of loose package,5 cases of wet package,11 cases of damage,and the closure performance qualification rate was 82.50%.The closure performance qualification rate of the experimental group was higher than that of the control group,and the difference was statistically significant(P＜0.05).Altogether 10 surgical dressings were taken in each of the two groups and stored for 7,14,30,60,90 and 180 days for bacteriological testing,and the results showed that the number of positive bacterial cultures in the experimental group and the control group was both 0 on 7 and 14 days.The number of positive bacterial cultures in the experimental group was 0 at 30,60,90,and 180 days,while that was positive in the control group at 30,60,90,and 180 days.There were statistically significant differences in the positive bacterial cultures between the two groups at 30,60,90,and 180 days(P＜0.05).Conclusion In terms of closure performance,the closure performance of the sterile dressing package of the medical new-type textile packaging is better than that of the sterile dressing package of the medical ordinary cotton cloth.In terms of bacteriostasis effect,the medical new-type packaging can effectively block bacteria within 180 days,while the medical ordinary cotton cloth packaging can effectively block bacteria within 14 days,but there is no guarantee to effectively block bacteria after 14 days.Therefore,medical new-type textile is worth promoting and using in sterilization supply center packaging.
