NCT03656406

Brief Summary

The investigators evaluate the effect of postural change on the bronchial cuff pressure (BCP) of double-lumen endotracheal tube (DLT) in patients undergoing thoracic surgery, by observing the pressure of the bronchial cuff before and after lateral decubitus positioning.

Outcome Measures

Primary Outcomes (1)

  • Change of the maximum bronchial cuff pressure (BCP) which does not exceed 40 cmH2O with no air leak from supine to lateral decubitus position

    A cuff-manometer will be connected to the valve of the pilot balloon of bronchial cuff via a three-way stopcock. And then, the BCP will be assessed, while inflating the cuff with air in 0.5 ml increments from 0 to 3.0 ml. If the BCP exceeds 40 cmH2O during expansion by increasing 0.5 ml from 0 to 3.0 ml, we will stop inflating the bronchial cuff with air and record the bronchial cuff volume (BCV) and BCP up to the last numerical value. During the pressure measurement, air leak or seal around the bronchial cuff will be assessed at each time point when inflating the cuff in 0.5 ml increments.

    1. In supine position, 2 minutes after the completion of confirming the double-lumen endotracheal tube (DLT) position via fiberoptic bronchoscope (FOB) 2. In lateral position, 2 minutes after the completion of confirming the DLT position via FOB

Secondary Outcomes (2)

  • The incidence of the patients whose maximum BCP exceed 40 cmH2O after lateral positioning

    1. In supine position, 2 minutes after the completion of confirming the DLT position via FOB 2. In lateral position, 2 minutes after the completion of confirming the DLT position via FOB

  • The minimum BCV that is the smallest bronchial cuff volume without air leakage

    1. In supine position, 2 minutes after the completion of confirming the DLT position via FOB 2. In lateral position, 2 minutes after the completion of confirming the DLT position via FOB

Interventions

After the DLT intubation, the patient is placed in lateral decubitus position

The pressure of the bronchial cuff should be measured with cuff-manometer in supine position, and then measurement should be repeated after lateral positioning.
