Comparison of Extubation Outcomes Following T-piece Trial versus Pressure Support/Continous Positive Airway Pressure in Postsurgical Patients

Abstract

Background: Pressure support with continuous positive airway pressure (CPAP) and T-piece trials are the most common spontaneous breathing trial used to test readiness for extubation. Aim: We aimed to compare extubation failures defined by the need for reintubation within 48 h following T-piece trial versus extubation directly from pressure support (PS) ventilation in postoperative patients. Patients and Methods: This was a prospective cross-sectional study conducted in the postsurgical patients. Hemodynamic parameters and respiratory variables were measured before and after weaning trials. Outcomes after extubation, need for noninvasive-assist ventilation following extubation, duration of oxygen therapy, and time of shifting from the Intensive Care Unit (ICU) were also recorded. Results: Fifty patients needed mechanical ventilation postoperatively were recruited for the study. No significant differences were seen in the rate of extubation failures between PS- and T-piece groups. Rapid shallow breathing index recorded at the start of weaning was significantly higher in the T-piece group (P
