Comparison of Oxygen Saturation Between Nasal High-Flow Oxygen and Conventional Nasal Cannula in Obese Patients Undergoing Dental Procedures With Deep Sedation: A Randomized Crossover Trial
نویسندگان
چکیده
Purpose In anesthetic management, it is widely accepted that obese patients are more likely to suffer airway obstructions and reductions in arterial oxygen saturation (SpO2). Therefore, important take special measures prevent desaturation during the deep sedation of patients. This clinical study examined whether use nasal high-flow systems (NHFS) keep higher SpO2 reduced hypoxemia than conventional cannula with intellectual disabilities for dental treatment. Materials Methods Eighteen (body mass index: >25) who underwent were enrolled. each case, was induced using propofol maintained at a bispectral index 50 70. The subjects randomly assigned control administration (5 L/min via cannula) or NHFS (40% O2, 40 L/min, 37 °C) arm alternate shifts as crossover trial. primary endpoint minimum value, incidence treatment also evaluated. Results mean value significantly (95.8 ± 2.1 % vs 93.6 4.1 %, P = 0.0052, 95% confidence interval: 0.608-3.947). Hypoxemic episodes (SpO2: ≤94%) occurred 3 cases (16.7%) 11 (61.1%) (P 0.0076, odds ratio: 0.127, interval 0.0324 - 0.630). Conclusion resulted

BACKGROUND The Oxymizer® is a special nasal cannula that provides a higher luminal diameter in combination with an incorporated oxygen (O2) reservoir. It is assumed that a higher O2 concentration can be delivered breath by breath in order to increase oxygenation. OBJECTIVE We aimed to investigate the effects of the Oxymizer on endurance time in comparison to a conventional nasal cannula (CNC)...
