Cerebral Oximetry With Near-infrared Spectroscopy and Negative Postoperative Behavioral Changes in Pediatric Surgery

Children undergoing urological surgery also required of locoregional blockade. Anesthetic induction was achieved with high concentration sevoflurane 6-8% (Sevorane®, Abbvie) and oxygen 50%. Anesthetic maintenance was done with sevoflurane 2-3%, 50% O2/air mixture, fentanyl 1 µg.kg.-1 iv, and rocuronium 0.3 µg.kg.-1 iv if required. Electrocardiogram (ECG), non-invasive arterial pressure, pulse oximetry, end-tidal carbon dioxide and cerebral NIRS oximetry was monitoring by using an INVOSTM5100 (Somanetics Corporation, Troy, MI, USA).
