Pressure versus volume-controlled ventilation with BASKA mask airway in laparoscopic cholecystectomy: A randomized clinical study

Background The best ventilation mode that suits with LMAs is still unclear. In this study, we investigated the ventilatory performance of Baska masks in patients who underwent elective laparoscopic cholecystectomy under general anaesthesia and pneumoperitoneum either volume-controlled (VCV) or pressure-controlled (PCV) mode.Methods Fifty-Six ASA I – II, cholecystectomy, were randomly classified into VCV (n = 28) PCV groups. lung was ventilated a tidal volume 8 ml/kg group. It initially using an inflating pressure delivered maximum 35 cmH2O primary outcome intraoperative oropharyngeal leak (OLP) mask. Secondary outcomes mechanics, arterial carbon dioxide levels, perioperative adverse effects.Results After inflation, OLP, peak inflation (PIP), mean (Pmean), PaCO2, end-tidal CO2 significantly increased, calculated dynamic compliance decreased both modes. All variables partially returned to baseline after deflation. Patients demonstrated lower PIP PaCO2 levels but higher statistically comparable OLP-PIP difference fraction.Conclusion showed compliance, fraction. However, modes provided effective mask maintained OLP throughout procedure difference.
