Duration of anesthesia: Short—less than 15 min; medium—between 15 and 60 min; long—longer than 60 min. Monitoring: Level of monitoring: Basic: Monitoring was performed using a stethoscope/pulse palpation, respiratory rate, and temperature only. Average: Clinical and non-invasive instrumental monitoring (pulse oximetry, capnography, ECG, non-invasive arterial pressure). Advanced: Invasive instrumental monitoring (cardiac output, invasive arterial pressure, blood gases). Hospitalization: If the patient was hospitalized (only during the day or overnight) or not
