摘　　要：目的通过对神经内科重症监护病房(NICU)的空气细菌学动态监测,指导制定不同状态的病房个体化空气消毒方案。方法应用病房空气环境定期采样的方法,进行动态监测2010年5月-2012年12月NICU空气环境的细菌学特征,选取有6张病床大房间和2张病床小房间的病房空气环境作为监测对象,根据不同时间段监测NICU空气环境的细菌学分布特征,根据监测结果适时调整NICU空气环境消毒方案,并对其消毒效果进行动态监测。结果 NICU大病房空气环境中的细菌数量(201.17±32.25)CFU/m3,高于小病房细菌数量的(99.22±25.96)CFU/m3(F=2.66,P<0.05);随着消毒方案的调整,大房间7个不同消毒方案阶段空气环境中细菌数量分别为(234.38±29.69)、(195.45±35.05)、(231.25±42.70)、(193.75±23.94)、(193.75±22.16)、(200.00±22.36)、(187.50±19.94)CFU/m3,差异有统计学意义(F=3.09,P<0.05);小房间6个阶段的空气中细菌数量分别为(140.63±22.90)、(95.45±25.16)、(100.00±20.41)、(89.58±16.71)、(87.50±13.69)、(93.75±18.84)CFU/m3,差异也有统计学意义(F=7.43,P<0.01)。结论在NICU空气细菌学动态监测结果指导下制定的个体化空气环境消毒方案,可以进一步提高NICU空气的消毒效果和有效地阻断医院感染的空气传播途径。OBJECTIVE To performed dynamical bacteriological monitoring of air in the neurological intensive care unit （NICU） so as to formulate individualized air disinfection programs for the wards under different states. METHODS By means of the regular sampling for the air environment, the bacteriological monitoring of the air environment of NICU was performed from May 2010 to Dec 2012, then the air environments of the big wards with 6 beds and the small wards with 2 beds were chosen as the monitoring objects, the bacteriological distribution of the air disinfection of NICU was monitored at different time, the air disinfection programs were adjusted in a timely manner according to the result of monitoring, and the disinfection effect was dynamically monitored. RESULTS The bacterial colony counts of the big ward were（201.17±32.25）CFU/ma , more than （99.22±25.96）CFU/ma of the small ward（F= 2.66, P〈0.05）. With the disinfection programs adjusted, the bacterial colony counts of the air environment of the seven disinfection programs for the big wards were （234.38±29.69）, （195. 45±35.05）, （231.25±42.70）, （193. 75±23.94）, （193. 75±22. 16）, （200. 00±22.36）, and （187.50±19.94）CFU/m3, respectively, the difference was statistically significant（F= 3.09,P〈0.05） ; the bacterial colony counts of the air environment of the six disinfection programs for the small wards were （140. 63±22.90）, （95.45±25.16）, （100. 00 ±20.41）, （89. 58±16.71）, （87. 50±13.69）, and （93.75±18.84）CFU/ma, respectively, the difference was also statistically significant （F=7.43,P〈0.01）. CONCLUSION To formulate the individualized air environment disinfection programs based on the guidance of the result of dynamical monitoring of bacteriology can further improve the air disinfection effect and effectively cut off the air transmission of nosocomial infections in NICU.
