概括
左双光管 (DLT) 的个性化旋转改善了胸部外科手术中首次安置成功的情况. 这种以CT扫描为指导的方法,与标准旋转相比,还可以减少呼吸道损伤和术后症状.
科学领域:
- 麻醉学 麻醉学
- 胸部外科手术 胸部外科手术
- 医疗成像医学成像
背景情况:
- 传统的左双光管 (DLT) 放置成功率在第一次尝试时低于80%.
- 标准的90°逆时针旋转可能是低于最佳的,因为支气管分支解剖学的变化.
- 精确的DLT放置对于胸部手术期间有效的肺部隔离至关重要.
研究的目的:
- 为了比较个性化与标准旋转对左边DLT放置的有效性.
- 评估个性化轮换对第一次尝试成功率的影响.
- 评估呼吸道损伤和术后症状的发生率.
主要方法:
- 一项随机对照试验招募了556名接受选择性胸部手术的成年患者.
- 个性化组的旋转度是通过手术前CT测量左侧主要支气管角度来确定的.
- 对照组接受了标准的90°逆时针旋转.
主要成果:
- 在个人化组 (91.4%) 和对照组 (82.6%) (P=0.02) 中,首次尝试DLT安置的成功率明显高于对照组 (82.6%) (P=0.02).
- 个性化组的卡里纳粘膜损伤率较低 (14.0%与19.6%,P=0.041).
- 在个性化组中,术后喉痛和声显著减少 (分别P<0.001和P<0.05).
结论:
- 基于手术前CT的左DLT的个性化旋转,在成人胸部手术中提高了第一次安置成功的成功率.
- 这种量身定制的方法可以减少呼吸道创伤,并改善手术后的患者舒适度.
- 手术前基于CT的个性化旋转是优化DLT安置的一个有价值的技术.

Endotracheal Intubation I: Procedure
1.2K
Endotracheal or ET intubation is a critical medical procedure used to secure a patient's airway, often in acute respiratory distress, apnea, upper airway obstruction, ineffective clearance of secretions, high risk for aspiration, or during general anesthesia.
The ET tube comprises various components, including a standard adaptor to attach a bag-valve-mask (BVM) or ventilator, a cuff, a pilot balloon, and radiopaque markings along its length to measure the insertion distance. The tube sizes...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy
192
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...
