Although nasal mask ventilation has demonstrated effectiveness for continuous positive airway pressure (CPAP) in obese patients with obstructive sleep apnoea (OSA), it has not yet been applied to the induction of anaesthesia. This study evaluated the efficacy of nasal mask ventilation against standard face mask ventilation in anaesthetised obese patients with body mass index (BMI)>25 kg\/m\n 2<\/jats:sup>\n .\n <\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n \n Ninety adult patients with BMI >25 kg\/m\n 2<\/jats:sup>\n were randomly assigned to receive either facemask (Group FM) or nasal-mask (Group NM) ventilation during induction of GA. Expired tidal volume (Vt\n E<\/jats:sub>\n ), air leak, peak inspiratory pressure (PIP), plateau pressure (P\n PLAT<\/jats:sub>\n ), oxygen saturation (SpO\n 2<\/jats:sub>\n ), and end-tidal carbon dioxide (EtCO\n 2<\/jats:sub>\n ) were recorded for10 breaths, and their mean was analysed.\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n The mean (standard deviation) Vt\n E<\/jats:sub>\n measured was not significantly higher in Group NM [455.98 (55.64) versus 436.90 (49.50) mL,\n P<\/jats:italic>\n = 0.08, degree of freedom (df):88, mean difference (95% confidence interval [CI]) \u221219.08 (\u221241.14, 2.98) mL].
