摘　　要：目的探讨普通病房、床单位细菌污染状况及臭氧消毒机对床单位消毒的效果。方法对2个病区普通病房15个床单位的被、褥和床垫于臭氧消毒前后分别采样进行细菌定量培养和菌种鉴定。结果床单位污染严重,污染率为100.0%,并检测条件致病菌和致病菌;采用臭氧消毒后床单位菌量明显下降,菌种明显减少。结论被、褥污染严重,床垫次之,建议对被、褥、床垫定期清洗或更换,患者出院后,将床单位送到消毒间进行消毒后再使用。OBJECTIVE To explore the bacterial contamination of bed unit in common ward and disinfectant efficacy of ozone sterilizer.METHODS The samples from quilts,cotton-padded and other mattresses of 15 bed units from two common wards before and after ozone sterilizer disinfection were collected to survey the quantitative culture and identification of bacterial strains.RESULTS The bacterial contamination of bed unit was heavy,and the contamination rate was 100.0%.Opportunistic and other pathogens could be detected out.After ozone sterilizer disinfection,the quantity of bacteria significantly decreased.CONCLUSIONS The quilts and cotton-padded mattresses and then the other mattresses is heavy.are heavly contaminated.We advice that the bedding should be cleaning or replacing regularly,and bed units should be disinfected with ozone sterilizer after patients discharged.
