Details and patient eligibility

About

The aim of this clinical trial is to find out the first success rate of double lumen intubation in the lateral position in thoracic surgery, it will also find out the safety of double lumen tube intubation in the lateral position. The trial aims to answer the following key questions

Does intubation in lateral position improve the first-time success rate of double-lumen intubation compared with in the supine position? What medical problems can participants experience during double lumen tube intubation in the lateral position? The researchers will compare double lumen intubation in the lateral position vs supine position to see if the position is effective in the success rate of double lumen intubation.

Participants will

Use the supine or lateral position during intubation

0 participants in 2 patient groups

DLT placement performed in lateral position

Experimental group

Description:

In the lateral position group, patients were positioned laterally (as required for surgery) before anesthesia induction. After anesthesia induction, Double lumen tube placement was performed while the patient remained in the lateral position.

Treatment:

Procedure: DLT placement performed in lateral position

DLT placement performed in supine position

No Intervention group

Description:

A double-lumen tube is typically carried out with the patient in the supine position, which is a standard procedure in thoracic surgery.
