Abstract :

AIM OF STUDY: This study evaluates the effectiveness and safety of two strategies, Pressure support ventilation (PSV) and T piece ventilation for weaning adult patients who require elective post operative mechanical ventilation for at least 12 hours, measuring weaning success and other clinically important outcomes. MATERIALS & METHODS: In our study 60 subjects was chosen (Group A–Weaning from mechanical ventilation after PSV & Group B– Weaning from mechanical ventilation after T Piece ventilation) RESULTS; Mean heart rate was lower, Mean systolic blood pressure was lower, Mean diastolic blood pressure was lower, Mean SPO2 was better, Mean ETCO2 was lower, Mean PH was better, Mean PaO2 was higher, Mean PaCO2 was lower, Mean duration of Mechanical ventilation was lower, Reintubation was lower in PSV group, than T piece group which was statistically significant. CONCLUSION : I conclude that weaning the patients from mechanical ventilator who have undergone upper abdominal surgeries can be done by Pressure support ventilation or by T piece with O2–6L/min. Considering the better hemodynamic stability, gas analysis, less duration of mechanical ventilation, lesser incidence of reintubation, I conclude pressure support ventilation is superior in weaning the patient from mechanical ventilator than T–piece ventilation
