To compare the performance of various types of airflow system in operating theatre.
Besançon Hospital has three types of airflow system in operating theatre: laminar (unidirectional) flow, stabilized flow and turbulent flow. We have compared performances of these airflow systems during operations by evaluating several indicators: number of airborne particles, microbial contamination, kinetics of decontamination, rate of mixing and an index of functionality.
At rest, performances of stabilized flow are close to these of laminar flow. On the other hand, during operations, the laminar flow is the single airflow system to reach the class B10.
Our study suggest that laminar flow should be used for prosthetic orthopaedic surgery. However, clinical studies are needed to confirm the superiority of laminar airflow systems in operating theatre.
比较手术室中不同类型气流系统的性能。
贝桑松医院手术室有三种气流系统：层流（单向）气流、稳定气流和紊流。我们通过评估几个指标来比较这些气流系统在手术过程中的性能：空气中微粒数量、微生物污染、净化动力学、混合率和功能指数。
在静止状态下，稳定气流的性能与层流相近。另一方面，在手术过程中，层流是唯一能达到B10级别的气流系统。
我们的研究表明，层流应用于人工骨科手术。然而，需要进行临床研究来证实手术室中层流气流系统的优越性。
