研究目的:

通过单中心、前瞻性、随机对照试验设计,比较双腔支气管导管与支气管封堵器在胸腔镜肺切除术中对患者术后7天内肺部并发症复合发生率的影响,为临床实践中肺隔离技术的优化选择提供高级别循证依据。  

Objectives of Study:

This single-center, prospective, randomized controlled trial is designed to compare the effects of double-lumen endobronchial tubes (DLTs) versus bronchial blockers (BBs) on the composite incidence of postoperative pulmonary complications (PPCs) within 7 days following video-assisted thoracoscopic lung resection, thereby providing high-level evidence to guide the optimal selection of lung isolation techniques in clinical practice.

Randomization Procedure (please state who generates the random number sequence and by what method):

Eligible participants were numbered according to the order of admission and randomly assigned to the DLT or BB group in a 1:1 ratio. An independent researcher was responsible for implementing the randomization scheme. The randomization strategy used was permuted block randomization, with block sizes randomly set at 4 or 6, implemented using the blockrand package in R.
