Summary:Objective　To investigate the effects of different arterial partial pressure of carbon dioxide (PaCO2) on regional cerebral oxygen saturation (rScO2) in robot assisted laparoscopic pyeloplasty (RALP) in children. Methods　Forty-five children who received RALP in Pediatric Urology Department of the Seventh Medical Center of Chinese PLA General Hospital from February 2019 to February 2020 were selected as the study subjects, by adjusting tidal volume and respiratory rate maintained PaCO2 at 35-45 mmHg (group N), 30-34 mmHg (group M) and 25-29 mmHg (group L) with 15 patients in each group. Before anesthesia (T0), 10 min after endotracheal intubation (T1), before lateral decubitus surgery (T2), 30 min after pneumoperitoneum (T3), 10 min after pneumoperitoneum (T4), and 10 min after recumbent position (T5), rScO2 of affected side, percutaneous pulse oxygen saturation (SpO2), heart rate (HR), mean arterial pressure (MAP), pharyngeal temperature (T), pH and hemoglobin (Hb) were recorded respectively.
