Comparison of Reintubation Outcome After Spontaneous Breathing Trial With T-Tube and Pressure Support Ventilation

Abstract

Background- Spontaneous breathing trial is one of the most promising procedure to successfully extubate a patient from mechanical ventilation. Commonly used modalities for weaning are PSV and T-tube. The aim of this study is to compare the re-intubation rates between these two strategies. This is an obse Methodology- rvational study done in the Central ICU under Department of Anaesthesiology, Assam medical college and hospital during the time period of June 2021 to May 2022. The study participants were recruited based on inclusion and exclusion 1 criteria. The sample size was calculated to be 66 [33 in each group] taking the reference of C.Subira . Demographic details and ASA status was obtained and once patient's clinical condition was improved they were put into spontaneous breathing trial either with T-tube or PSV. Hemodynamic changes were noted and if patients were tolerating the trial, extubation was done and they were observed. Re-intubation rates following 48 hours of extubation were compared between both the groups. Statistical analysis was done with SPSS software. Categorical variables were expressed in terms of numbers and percentages and p value <0.05 was considered stastistically significant. In our study demographics showed no si Results- gnificant variation. Re-intubation rates were more in Ttube group (24.24%) compared to PSV (12.12%) but was statistically insignificant. Our study s Conclusion- howed comparable rates of re-intubation between both the groups of T-tube and PSV
