To compare the effect of high-flow nasal cannula oxygen therapy (HFNC) from that of conventional nasal cannula oxygen therapy (CNC) on oxygenation during prostate-targeted needle biopsy under total intravenous anesthesia in high-risk patients with obstructive sleep apnea syndrome (OSAS).
We randomly assigned 64 high-risk OSAS patients to two groups of an equal number to receive HFNC and CNC, respectively, under total intravenous anesthesia. We recorded the incidence rates of SpO2<95% and the lowest SpO2 during surgery, the mean arterial pressure (MAP), heart rate (HR) and oxygen saturation (SpO2) upon entering the operation room (T0), at the beginning (T1) and the end of surgery (T2) and at 30 minutes postoperatively (T3), as well as arterial partial pressure of oxygen (PaO2) and arterial partial pressure of carbon dioxide (PaCO2) at T0 and T2, and the incidence rates of airway intervention and adverse events, followed by comparison of the parameters between the two groups.
Both the lowest SpO2 and PaO2 were
