呼吸内科门诊雾霾天气病原菌检测及消毒效果分析

Detection of haze pathogenic bacteria in outpatient of department of respiratory medicine in hospital and the effect analysis of disinfection

目的 探讨呼吸内科门诊雾霾天气病原菌检测及消毒效果.方法 选取2015年2月—2016年2月唐山工人医院呼吸内科门诊20个雾霾天气为观察组,选择同期20个晴朗天气为对照组,比较其病原菌检测结果 及采用相同消毒方式进行室内消毒后的消毒效果.结果观察组消毒前空气中菌落数（2719±152）cfu/m3,对照组为（2667±167）cfu/m3,差异无统计学意义（P〉0.05）;观察组飘尘浓度（0.523±0.122）mg/m3,高于对照组的（0.373±0.055）mg/m3,差异有统计学意义（P〈0.05）;消毒后观察组空气中菌落数（497±94）cfu/m3、飘尘浓度（0.185±0.037）mg/m3,均高于对照组的（408±81）cfu/m3、（0.091±0.038）mg/m3,差异有统计学意义（P〈0.05）;消毒后观察组在上午、下午的空气细菌总数分别为（497±94）cfu/m3、（633±79）cfu/m3,高于对照组的（408±81）cfu/m3、（561±66）cfu/m3,差异有统计学意义（P〈0.05）;空气净化后,观察组的空气飘尘浓度上午为（0.331±0.084）mg/m3、下午为（0.503±0.105）mg/m3,均高于对照组的（0.262±0.067）mg/m3、（0.285±0.094）mg/m3,差异有统计学意义（P〈0.05）.结论 雾霾天气呼吸内科门诊室各项病原菌检出率均高于晴朗天气,且消毒效果低于晴朗天气,应适当延长雾霾天气时呼吸内科门诊室消毒时间及消毒次数.

Objective To research and analysis in the hospital respiratory medicine haze weather pathogen detection and disinfection effects.Methods From February 2015 to February 2016, a total of 20 haze weather days were chosen as observation group, and another 20 sunny weather days were selected for control group at the same period. In two groups in Tangshan worker＇s Hospital Respiratory Medicine Clinic, the suffering from pathogenic bacteria was detected, and the same disinfection effects of ward were compared.Results Before disinfection, the number of bacteria in air in the observation group was （2719±152）cfu/m3, while the control group was （2667±167）cfu/m3, and there was no difference between the two groups （P〉0.05）. But the observation group concentration of floating dust （0.523±0.122）mg/m3, significantly higher than （0.373±0.055）mg/m3 in the control group （P〈0.05）; after disinfection of observation group, the air number （497±94）cfu/m3, concentration of floating dust （0.185±0.037）mg/m3, were significantly higher than （408±81）cfu/m3,（0.091±0.038）mg/m3 in control group （P〈0.05）; before disinfection, air bacteria was not significantly different, in the observation group, air bacteria at noon and afternoon after disinfection （497±94）cfu/m3, （633±79）cfu/m3, were significantly higher than （408±81）cfu/m3, （561±66）cfu/m3 of the control group （P〈0.05）; after air purification, the air concentration of dust in the observation group were （0.503±0.105）mg/m3 in morning and （0.331±0.084）mg/m3 in afternoon, were significantly higher than those in control group [（0.262±0.067）mg/m3, （0.285±0.094）mg/m3], and the differences were statistically significant （P〈0.05）.Conclusions The detection rate of pathogenic bacteria in the respiratory medicine of the fog and haze days is significantly higher than that in the fine weather, and the disinfection effects is significantly lower than that of the fine weather, the length and rate of disinfection should be increased in fog and haze days.
