The neurodevelopment status of patients was assessed using the Ages Stages Questionnaires. The primary outcome was the occurrence of neurodevelopmental delay among patients at different intervals following pediatric liver transplantation. Secondary outcomes included the duration of mechanical ventilation, rates of re-intubation, length of ICU stay, postoperative hospitalization, and intraoperative comparisons of mean arterial pressure (MAP), arterial partial pressure of oxygen (PaO<jats:sub>2<\/jats:sub>), arterial partial pressure of carbon dioxide (PaCO<jats:sub>2<\/jats:sub>), and hemoglobin (Hb) concentration.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 119 patients were included in the statistical analysis and assigned to high saturation group (HS) and low saturation group (LS) according to the average intraoperative cerebral tissue oxygen saturation values. Following adjustment for PELD scores, significant differences between the two groups were observed for the incidence of neurodevelopmental delay in communication at 1 and 3 months follow-up (<jats:italic>P<\/jats:italic>\u2009=\u20090.019 and <jats:italic>P<\/jats:italic>\u2009=\u20090.020, respectively), fine motor at six months follow-up (<jats:italic>P<\/jats:italic>\u2009=\u20090.014), and problem-solving abilities at one year follow-up (<jats:italic>P<\/jats:italic>\u2009=\u20090.047).
