Moxa-Stick Suffumigation for Disinfecting Air in Hematology and Hematopoietic Stem Cell Transplantation Wards with Class 100 Laminar Flow

【摘要】 Objective:To evaluate the effect of moxa-stick suffumigation in the hematology and hematopoietic stem cell transplantation(HSCT)wards with luminar flow.Methods:The plate exposure method was used to measure the effect of air-disinfection of moxa-stick suffumigation in hematology and HSCT wards.The yearly average qualified rates of air sampling in HSCT wards were evaluated from 2007 to 2010.To further investigate the disinfecting effect of moxa-stick suffumigation,the colony counts of common pathogens(including Staphylcoccus aureus and Pseudomonas aeruginosa)before and after moxa-stick suffumigation were compared.Results:The mean air quality rates of the HSCT wards with class 100 laminar flow were all above90.0%(91.2%-96.2%)from 2007 to 2010.Moxa-stick suffumigation effectively decreased the presence of bacteria in the hematology ward’s air(P<0.01).The most notable effect was the drastic reduction in the colony counts of Staphylococcus aureus and Pseudomonas aeruginosa on the blood plates exposed to air treated with moxa-stick suffumigation(77.1±52.9 cfu/m~2 vs 196.1±87.5 cfu/m~2,P<0.01;and 100.2±35.3 cfu/m~2 vs371.5±35.3 cfu/m~2,P<0.01).Conclusion:Moxa-stick suffumigation proved to be a reliable and effective airdisinfection method for hematology and HSCT wards,and hence,it should be employed extensively.更多还原
