Abstract

OBJECTIVE

To describe the characteristics of airborne micro-organisms in the environment in a Chinese neurological intensive care unit (NICU).

METHODS

This prospective study monitored the air environment in two wards (large and small) of an NICU in a tertiary hospital in China for 12 months, using an LWC-1 centrifugal air sampler. Airborne micro-organisms were identified using standard microbiology techniques.

RESULTS

The mean ± SD number of airborne bacteria was significantly higher in the large ward than in the small ward (200 ± 51 colony-forming units [CFU]/m(3) versus 110 ± 40 CFU/m(3), respectively). In the large ward only, the mean number of airborne bacteria in the autumn was significantly higher than in any of the other three seasons. A total of 279 airborne micro-organisms were identified (large ward: 195; small ward: 84). There was no significant difference in the type and distribution of airborne micro-organisms between the large and small wards. The majority of airborne micro-organisms were Gram-positive cocci in both wards.

CONCLUSION

These findings suggest that the number of airborne micro-organisms was related to the number of patients on the NICU ward.

摘要

目的

描述中国一家神经重症监护病房（NICU）环境中空气传播微生物的特征。

方法

本前瞻性研究使用LWC - 1离心式空气采样器，对中国一家三级医院NICU的两个病房（大病房和小病房）的空气环境进行了为期12个月的监测。采用标准微生物学技术鉴定空气传播微生物。

结果

大病房空气中细菌的平均数量±标准差显著高于小病房（分别为200±51菌落形成单位[CFU]/m³和110±40 CFU/m³）。仅在大病房，秋季空气中细菌的平均数量显著高于其他三个季节中的任何一个季节。共鉴定出279种空气传播微生物（大病房：195种；小病房：84种）。大病房和小病房之间空气传播微生物的类型和分布没有显著差异。两个病房中大多数空气传播微生物都是革兰氏阳性球菌。
