| Total fluid intake (mL) | 2214.71±545.19 | 2320.00±453.76 | 0.511 |
| Total urine output (mL) | 457.06±273.77 | 382.50±211.06 | 0.431 |
| SpO at T1 | 97.55±1.88 | 98.30±1.22 | 0.142 |
| SpO at T2 | 98.95±1.19 | 99.05±0.76 | 0.753 |
| PaO at T3 (mmHg) | 98.95±1.19 | 95.0±24.80 | 0.945 |
| Operative duration (min) | 179.0±49.2 | 185.0±45.0 | 0.692 |
| Anesthesia duration (min) | 226.18±50.12 | 243.30±49.09 | 0.282 |
| PaO – partial pressure of arterial oxygen; SpO – peripheral oxygen saturation. C – control; RM – alveolar recruitment maneuver. T1 – before the induction of anesthesia; T2 – at the end of the surgical procedure; T3 – 30 min after extubation. Data are presented as the mean±SD for continuous variables. * test comparing differences within the individual study groups. | |||
