CT-Guided Versus Traditional Selection of Double-Lumen Tube Size for One-Lung Ventilation in Thoracic Surgery: A Prospective Study

Detaljeret beskrivelse

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.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: CT-Guided Group
Participants will undergo preoperative CT measurement of the bronchial diameter 10 mm distal to the carina. DLT size will be selected using manufacturer-recommended correlation charts based on CT measurements.
Andet: CT-Guided Group (Intervention)
Participants will undergo preoperative CT measurement of the bronchial diameter 10 mm distal to the carina. DLT size will be selected using manufacturer-recommended correlation charts based on CT measurements.
Aktiv komparator: Conventional Group
DLT size will be selected using standard clinical criteria based on patient demographics, according to institutional standard tables.
Andet: Conventional Group (Control)
DLT size will be selected using standard clinical criteria based on patient demographics, including sex, height, and weight, according to institutional standard tables.

Hvad måler undersøgelsen?

Primære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Successful selection of the correct DLT size on the first attempt (defined as optimal position and lung isolation without the need for tube exchange) using fiberoptic scope
Tidsramme: During the intraoperative period (at first attempt of double-lumen tube placement)
the correct placement of a double-lumen tube (DLT) on the first attempt, achieving optimal tracheobronchial position and effective lung isolation as confirmed by fiberoptic bronchoscopy, without the need for tube exchange or repositioning.
During the intraoperative period (at first attempt of double-lumen tube placement)
