Comparative study on Successful Extubation between using of spontaneous breathing trial with T-piece and Low-pressure support ventilation in infectious pneumonia patients of Internal Medicine Department in Somdejphrajaotaksin Maharaj Hospital

Abstract

Successful extubation affects the patient's health and reduces complications that may occur to the patient. This research has the objective to compare the success rates of extubation between using spontaneous breathing trial with T-piece and Low-pressure support ventilation. The study was a retrospective cohort study. Data were collected from January 2020 to December 2022. A purposive sample of 118 people was selected. Data were analyzed with the package program by using descriptive statistics (percentage, mean, median, standard deviation, interquartile range) and inferential statistics (Chi-square test, Fisher’s exact test, and T-test) Results: A total of 118 patients (66 in T-piece group and 52 in Low pressure support) were included in the analysis. The success rate of extubation within 72 hours was 93.9% and 90.4% in T-piece and Low-pressure support, respectively (p=0.505). Conclusion: The success rate of extubation between using of spontaneous breathing trial T-piece and Low-pressure support ventilator were not different. The choice of the two devices depends on the doctor's diagnosis and the patient's symptoms. Low pressure support ventilation is used initially and when the patient is no longer short of breath, the T-piece ventilation is switched to allow the patient to practice breathing on their own and successfully remove the trachea.
