Abstract

Objective To evaluate the difference of Pressure Support vs T-Piece vs Automatic Tube Compensation Ventilation Strategies during Spontaneous Breathing Trials on lung aeration. Methods Sixty-nine cases of mechanically ventilated patients who were prepared to undergo the first spontaneous breathing trial （SBT） in EICU of an affiliated Hospital of Medical University from June 2020 to January 2021 were included. They were randomly divided into T-Piece group, Pressure Support Ventilation （PSV） group and Automatic Tube Compensation （ATC） group for 30 minutes of SBT. After successful SBT, the tracheal intubation was removed within 24 hours. We observed the patients’ Lung Ultrasound Scores （LUS） with ultrasound before the beginning of SBT （T0）, at the end of SBT （T1） and 30 minutes after extubation （T2） in all patients. Results At the end of SBT, the LUS of the three groups were not significantly different （P > 0.05）. The LUS of patients in T-Piece , there was no significant difference in the changes from T1 to T2 （P > 0.05）. The LUS of patients in the PSV group and ATC group increased from T1 to T2 （P < 0.05）. Conclusion SBT strategy with pressure support is helpful for patients to pass SBT and ensure lung ventilation during SBT, however, T-tube SBT seems to be a better predictor of lung ventilation after extubation.
