Abstract

Background. To clarify the efficiency of mask O2 and high-flow O2 (HFO) treatments following cardiopulmonary bypass (CPB) in obese patients. Methods. During follow-up, oxygenization parameters including arterial pressure of oxygen (PaO2), peripheral oxygen saturation (SpO2), and arterial partial pressure of carbon dioxide (PaCO2) and physical examination parameters including respiratory rate, heart rate, and arterial pressure were recorded respectively. Presence of atelectasia and dyspnea was noted. Also, comfort scores of patients were evaluated. Results. Mean duration of hospital stay was 6.9 ± 1.1 days in the mask O2 group, whereas the duration was significantly shorter (6.5 ± 0.7 days) in the HFO group (). The PaO2 values and SpO2 values were significantly higher, and PaCO2 values were significantly lower in patients who received HFO after 4th, 12th, 24th, 36th, and 48th hours. In postoperative course, HFO leads patients to achieve better postoperative FVC (). Also, dyspnea scores and comfort scores were significantly better in patients who received HFO in both postoperative day 1 and day 2 (, resp.). Conclusion. Our study demonstrated that HFO following CPB in obese patients improved postoperative PaO2, SpO2, and PaCO2 values and decreased the atelectasis score, reintubation, and mortality rates when compared with mask O2.
