概括

减少手术室 (OR) 流量,包括门打开和人员移动,可以减少微生物污染. 这项研究发现OR流量与微生物沉积有很弱的相关性,这表明手术部位感染的可修改风险因素.

科学领域:

与医疗保健相关的感染
操作室污染操作室污染
微生物学微生物学

背景情况:

在手术室 (OR) 中,来自交通 (人员,门口) 的空气污染会导致微生物沉积在表面上.
这些微生物沉积物是手术部位感染 (SSI) 的潜在贡献者.

研究的目的:

评估在特定手术过程中手术室 (OR) 流量和微生物沉积之间的关联.
确定OR交通中的潜在可修改因素,可以降低污染风险.

主要方法:

采用混合方法方法,结合非参与者观察和阿加沉板测试.
数据是在中西部卫生系统的结肠手术和腹部切除术期间收集的.
营养室流量指标 (门口打开,人员数量) 与微生物沉积水平相关.

主要成果:

门的打开与手术持续时间有很强的相关性 (r=0.72,P<0.0001).
总微生物沉积物与增加的门打开 (r=0.37,P<0.004) 和人员 (r=0.27,P=0.034) 呈现弱相关性.
大多数 (83%) 的伤口区存储值低于确定的门值.

结论:

虽然大多数微生物沉积物低于值,但OR流量是一个弱相关因素.
周围操作人员可以通过控制OR流量来潜在地减轻微生物污染的风险.
减少不必要的门打开和人员移动的策略可以提高手术场所的安全性.

Transmission-based Precautions II: Airborne and Protective Environment

Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Endoscopic Studies II: Thoracocentesis

Endoscopic Studies II: Thoracocentesis

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
