Double Lumen Tube Intubation

Keywords

Brief summary

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

Interventions

PROCEDUREDLT placement performed in lateral position

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.

Design outcomes

Primary

MeasureTime frameDescription
Successful First-Pass IntubationPeriproceduralThe primary outcome was the success rate of the first DLT intubation attempt.

Secondary

MeasureTime frameDescription
Intubation timePeriproceduralDefined 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.
Interval before surgeryPeriproceduralDefined as the time interval between the admission of patients in the operating room and the start of surgery.
p-PeakPeriproceduralpeak inspiratory pressure(p-Peak) during mask ventilation, total-lung ventilation(TLV) and one-lung ventilation(OLV)
Flexible bronchoscope usagePeriproceduralthe frequency of use of flexible bronchoscope
No. of intubation attemptsPeriproceduralNumber of patients who were successfully intubated on any attempt
early intubation-related complicationsPeriproceduralearly 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)
postoperative complicationsPeriproceduralpostoperative complications (sore throat, GRBAS scale, upper-arm discomfort, and nerve injury)
satisfaction scores.Periprocedural0 points: dissatisfied, 1 point: satisfied, 2 points: very satisfied.
the incidence of DLT malpositionPeriproceduralthe incidence of DLT malposition observed by flexible bronchoscope (DLT malposition was defined as movement \>1.0 cm to correct the DLT position)
