为了探讨臭氧消毒机对连台手术间空气消毒的最佳湿度和时间，在8间面积均为70 m2、朝向一致的手术间，用臭氧消毒机于首台手术前后及不同湿度(65%、70%、75%、80%、85%)、不同时间(10、15 min)下行空气消毒。结果首台手术前、后(未消毒时)细菌阳性手术间数比较，差异有极显著性意义(P＜0.01)；首台手术后消毒15 min，5种湿度条件下的细菌阳性手术间数比较，差异有显著性意义(P＜0.05)，其中65%、70%、75%湿度之间细菌阳性手术间数比较，差异无显著性意义(P＞0.05)，其分别与80%、85%湿度的细菌阳性手术间数比较，差异有极显著意义(均P＜0.01)；在80%～85%的相对湿度下消毒10、15 min，均达国家标准(细菌数≤69.3 cfu/m3)，两种消毒时间比较，差异无显著性意义(P＞0.05)。提示连台手术之间必须行空气消毒；最佳消毒相对湿度为80%～85%，时间为10～15 min。

In order to explore the optimal humidity and time of air disinfection for continuous operating room by ozone disinfector, air disinfection was performed in the 8 operating rooms with the size of 70 m2 and same orientation before and after the first operation at different humidity (65%、 70%、 75%、 80% and 85%) and different time points (10 min and 15 min). The results showed that there was a significant difference in the operating rooms for positive bacteria before and after the first operation (P<0.01). 15 min of disinfection after the first operation, the comparison of the operating rooms for positive bacteria under the humidity of 65%，70%， 75%, 80% and 85% showed a significant difference (P<0.05). The comparison of the operating rooms positive for bacteria contamination among the humidity of 65 % and 75 % showed no significant difference (P>0.05), but there was a very significant difference in the operating rooms for positive bacteria contamination at the humidity of 80% to 85% as comparison to those at the humidity of 65% to 75% respectively (P<0.01). National standard (bacteria contamination≤69.3 cfu/m3) was met after disinfection for 10 or 15 min at the humidity of 80% to 85% with the difference being not significant (P>0.05). It was suggested the air disinfection was necessary between the continuous operations. The optimal air humidity was 80% to 85% and the time was 10 to 15 min for best disinfecting results.
