Double-Lumen Tube Intubation in the Lateral Position Versus the Supine Position on First-Attempt Success Rate

xiangming fang

Overview

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

Conditions

Double Lumen Tube Intubation

Interventions

DLT placement performed in lateral positionPROCEDURE

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.

Outcomes

Primary Outcomes

Successful First-Pass Intubation

The primary outcome was the success rate of the first DLT intubation attempt.

Time frame: Periprocedural

Secondary Outcomes

No. of intubation attempts

Number of patients who were successfully intubated on any attempt

Time frame: Periprocedural

Intubation time

Defined as from the time when the laryngoscope passed between the patient's lips until the use of a fiberoptic bronchoscope to confirm the correct positioning of the DLT.

Time frame: Periprocedural

Interval before surgery

Defined as the time interval between the admission of patients in the operating room and the start of surgery.

Time frame: Periprocedural

p-Peak

peak inspiratory pressure(p-Peak) during mask ventilation, total-lung ventilation(TLV) and one-lung ventilation(OLV)

Time frame: Periprocedural

Flexible bronchoscope usage

the frequency of use of flexible bronchoscope

Time frame: Periprocedural

the incidence of DLT malposition

the incidence of DLT malposition observed by flexible bronchoscope (DLT malposition was defined as movement \>1.0 cm to correct the DLT position)

Time frame: Periprocedural

early intubation-related complications

early intubation-related complications (dental injury; hypoxemia; laryngospasm; bronchospasm; airway trauma; arrhythmia, including the salve of ventricular premature beats, ventricular fibrillation, and ventricular tachycardia; oral mucosal injury; and esophageal intubation)
