Comparison of Double Lumen Tube Location Verification Techniques in Single Lung Ventilation

Comparison of Double Lumen Tube Location Verification Techniques in Single Lung Ventilation: Auscultation, Fiberoptic Bronchoscopy, and Video Double Lumen Tube

The aim of this study was to compare auscultation, fiberoptic bronchoscopy (FOB) and video double lumen tube (VDLT) double lumen tube (DLT) location confirmation techniques in terms of intraoperative tube location confirmation time, number of tube dislocations, correction time of dislocations, FOB usage rates, lung deflation quality, postoperative sore throat, presence of hoarseness and cost in thoracic surgery patients undergoing one lung ventilation (OLV).

Study Overview

• Status: Completed
• Conditions: Lung Diseases; Lung Cancer
• Intervention / Treatment: Device: double lumen tube with video

Detailed Description

The single-center, prospective and observational study included 93 patients aged 18-84 years, American Society of Anesthesiology (ASA) I-III, who were to undergo one-lung ventilation in the lateral decubitus position by thoracic surgery under elective conditions. Patients were randomized into Group I: Group with confirmed tube location by auscultation, Group II: Group with confirmed tube location by FOB and Group III: The group in which double lumen tube with video was used. Demographic data of the patients, intubation times, tube site confirmation times, number of type dislocation, dislocation correction time, number and duration of FOB use, quality of lung deflation, presence of postoperative sore throat and hoarseness were recorded. The three groups were compared in terms of cost.

Grup III; The group in which double lumen tube with video was used	Device: double lumen tube with video; Methods used to confirm tube placement in one-lung ventilation: auscultation, fiberoptic bronchoscopy, and video to evaluate double-lumen tube use; Other Names: fiberoptic bronchoscope

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
verification of tube location	The primary endpoint is the identification of a method that allows the quickest confirmation of double-lumen tube location after intubation and possible intraoperative location changes.	during surgery

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
evaluation of complications	The secondary endpoint was to determine the superiority of three methods over each other in preventing complications that may occur due to inadequate tube location confirmation.	during surgery

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
cost effectiveness	The other endpoint is to determine the superiority of the three methods over each other in terms of reducing costs.	during surgery
