Abstract

BACKGROUND

The study investigated 35 orthopedic OTs [17 with mixed flow (M-OTs), 18 with turbulent flow (T-OTs)].

METHODS

The OTs were divided into two categories based on recurring architectural and construction solutions, collected by a survey form: type-A (recently built or renovated rooms), and type-B (other OTs). Assessment of microbial air contamination (colony forming units (cfu)/m3 obtained by active sampling via Surface Air System) was then performed.

RESULTS

In 97% of the OTs, a Total Viable Count (TVC) was within the limits recommended by ISPESL 2009; all A-type OTs, and 94% of B-type passed. The TVC of type-A OTs [median 15 cfu/m3, range 3-158] was lower than that of type-B OTs [median 28 cfu/m3, range 6-206], although the difference was not significant. The number of people in type-A [mean 8.6, range 6-11] was lower than in type-B [mean 9.6, range 7-13] OTs, and when adjusted to the volume of the OT (person/m3), showed a significant correlation with TVC (ρ = 0.383, p <0.05).

CONCLUSIONS

In conclusion, the structural factors examined do not appear to significantly affect the microbiological air quality at the specific sampling point. However, further investigations are required to identify the factors that have the greatest effect on TVC.

摘要

背景

本研究调查了35间骨科手术室[17间为混合流手术室（M-OTs），18间为紊流手术室（T-OTs）]。

方法

根据通过调查问卷收集的反复出现的建筑和构造解决方案，将手术室分为两类：A型（新建或翻新的房间）和B型（其他手术室）。然后对微生物空气污染进行评估（通过表面空气系统主动采样获得的菌落形成单位（cfu）/立方米）。

结果

在97%的手术室中，总活菌数（TVC）在意大利国家职业健康与安全研究所2009年推荐的限值范围内；所有A型手术室以及94%的B型手术室均达标。A型手术室的TVC[中位数为15 cfu/立方米，范围为3 - 158]低于B型手术室[中位数为28 cfu/立方米，范围为6 - 206]，尽管差异不显著。A型手术室的人数[平均8.6人，范围为6 - 11人]低于B型手术室[平均9.6人，范围为7 - 13人]，并且在根据手术室体积进行调整（人/立方米）后，与TVC显示出显著相关性（ρ = 0.383，p <0.05）。
