摘要
目的探讨床单位细菌污染状况及集中式清洗消毒的效果。方法随机选择使用过的56张床单位,床上用品采用压力蒸汽消毒器消毒,床架经清洗消毒器清洗消毒,对清洗消毒前后的床单位进行细菌学生物监测。结果床单位污染严重,污染率为100.00%;菌落数枕芯消毒前为(79.618±50.370)CFU/cm2、消毒后为(0.010±0.014)CFU/cm2、棉被消毒前为(30.291±15.021)CFU/cm2、消毒后为(0.012±0.013)CFU/cm2、床架消毒前为(30.218±13.788)CFU/cm2、消毒后为(0.005±0.006)CFU/cm2,消毒前后差异有统计学意义(P<0.05)。结论集中式统一清洗消毒床单位,有效的杀灭病原菌,是安全可靠的消毒法,提高了医疗护理质量,并预防医院感染。
OBJECTIVE To explore the bacterial contamination of bed units and the effect of centralized cleaning and disinfection. METHODS A total of 56 used bed units were randomly selected as the study objects, then the bedclothes were sterilized by using the pressure-stream disinfector, the bedstocks were cleaned and disinfected with the use of the washer-disinfector, and the bacteriological monitoring of the bed units was performed before and after the cleaning and disinfection. RESULTS The bed units were seriously contaminated wit the contamination rate of 100.00%. The bacterial colony counts on the pillow core were (79. 618 ! 50. 370)CFU/cm2 before the disinfection, (0. 010 _--q-0. 014)CFU/cm2 after the disinfectiom the bacterial colony counts on the quilts were (30. 291_--+-15. 021)CFU/cmz before the disinfection, (0. 0120. 013)CFU/cm2 after the disinfection; the bacterial colony counts on the bedstocks were (30.218 --t- 13.788) CFU/cmz before the disinfection, ( 0.005 -+- 0.006 ) CFU/ cm2 after the disinfection, with statistical significance (P〈 0.05). CONCLUSION The centralized cleaning and disinfection can achieve reliable effect on killing the pathogens, improve the medical nursing quality, and prevent nosocomial infections.
