NCT02729610

Brief Summary

Outcome Measures

Primary Outcomes (1)

  • clinically relevant laryngeal and bronchial morbidity

    incidence of clinically relevant laryngeal and bronchial morbidity will be recorded, including postoperative hoarseness, sore throat, and vocal cord injuries, pulmonary complications

    perioperative period

Secondary Outcomes (6)

  • Heart Rate

    perioperative period

  • Central Venous Pressure

    perioperative period

  • Blood Pressure

    perioperative period

  • the Duration of Ventilation

    The duration of ventilation in minutes will be recorded at time from intubation to extubation, an expected average of 18 hours.

  • Length of Postoperative Hospital Stay

    Length of postoperative hospital stay in days will be recorded which is defined as the time from surgery to hospital discharge, an expected average of 10 days

  • +1 more secondary outcomes

Study Arms (2)

DLT group

ACTIVE COMPARATOR

In this arm, patient will be intubated with a double lumen endotracheal tube

Device: double-lumen endotracheal tube (DLT group)

BB group

EXPERIMENTAL

In this arm, patient will be intubated with an endobronchial blocker

Device: endobronchial blocker (BB group)

Interventions

In this arm, after anesthesia induction, a double lumen endotracheal tube will be intubated for one-lung ventilation

DLT group

In this arm, after anesthesia induction, an endobronchial blocker will be intubated for one-lung ventilation

BB group
