概括
使用水下钻探的内镜耳部手术与显微镜技术相比,显著减少了空气中的颗粒. 这种方法降低了在手术室的骨解剖过程中空气传播感染的风险.
科学领域:
- 耳鼻喉科 耳鼻喉科 耳鼻喉科
- 手术技术 手术技术
- 感染控制 感染控制
背景情况:
- 耳科手术期间产生的空气中的颗粒可能会造成感染风险.
- 对粒子负荷的定量评估对于评估外科手术技术至关重要.
研究的目的:
- 量化比较空气中的颗粒物负载在跨通道内镜耳部手术 (TEES) 与微观耳部手术.
- 在表膜切除和乳腺切除手术中钻孔时评估颗粒负荷.
主要方法:
- 使用粒子计数器测量了0.3,0.5和1.0微米的粒子计数.
- 在TEES (水下钻探) 和微观耳部手术组中,在钻探前,钻探期间和钻探后进行了测量.
- 对11例TEES病例和5例微观耳部手术病例进行了粒子负荷分析.
主要成果:
- 与TEES相比,微观耳部手术在所有测量尺寸中产生了明显更高的空气中的颗粒负荷 (p < 0.01).
- 使用水下钻探的TEES在任何颗粒大小的程序之前,期间或之后都没有显著的粒子负载差异.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy
231
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Endoscopic Studies II: Thoracocentesis
325
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...
