CT-Guided vs Conventional DLT Sizing in Thoracic Surgery (CTDLT-SIZE)
CT-Guided Versus Traditional Selection of Double-Lumen Tube Size for One-Lung Ventilation in Thoracic Surgery: A Prospective Study
연구 개요
상태
상세 설명
This is a prospective, randomized, single-blinded controlled trial designed to compare CT-guided versus conventional methods for selecting double-lumen tube (DLT) size in patients undergoing thoracic surgery requiring one-lung ventilation. The study aims to evaluate whether preoperative computed tomography (CT)-based bronchial diameter measurement improves the accuracy of initial DLT size selection compared with conventional selection based on demographic parameters.
Eligible patients will be randomly assigned in a 1:1 ratio to either the CT-guided group or the conventional group.
