Clinical Trial Summary

Postoperative non-invasive ventilation (NIV) has been proposed as an attractive strategy to reduce morbidity and improve postoperative outcomes in obese subjects undergoing general anesthesia. Bariatric patients present a peculiar negative feature; the increased body mass index (BMI) correlates with loss of perioperative functional residual capacity (FRC), expiratory reserve volume (ERV) and total lung capacity (TLC), decreased up to 50% of preoperative values. The aim of the current randomized trial is to evaluate the efficacy of NIV in post-anaesthesia care unit (PACU) in reducing post-extubation acute respiratory failure and the consequent admission in intensive care units (ICU) after BIBP in obese adult patients.

Intervention

Device:
• Non invasive ventilation (NIV)
Patients allocated in NIV Group fulfilled a 120-minute cycle of PSV + PEEP with full-face mask. Ventilation was performed with a Draeger Ventilator with the following basic settings: DeltaPInsp 10 mmHg + PEEP 5 mmHg + Fio2 60%.
• Conventional Venturi Mask
Patients were offered VenturiMask with Fio2 60% at 15 l / m.
