Objective: Pneumoperitoneum can cause disruption in splanchnic perfusion. This study aims to investigate effects of pneumoperitoneum on splanchnic oxygenation during abdominal laparoscopic surgery in paediatric patients with NIRS (Near-Infrared Spectroscopy).Material and methods: A total of 45 patients between 1 and 4 years of age with ASA physical status I–II and scheduled to undergo abdominal laparoscopic surgery under general anaesthesia were enrolled in this prospective, observational surgery. No premedication was used. Standard monitoring and regional splanchnic saturation ($rSPcO_2$), regional cerebral oxygen saturation ($rSPcO_2$) with NIRS were established before anaesthesia. Anaesthesia was induced with an inhalational agent and maintained with an oxygen/air mixture and sevoflurane. Peripheral oxygen saturation ($SPO_2$), $rSPcO_2$, $rSPcO_2$, heart rate (HR), mean arterial pressure (MAP), end tidal $CO_2$ (Et-$CO_2$), and insufflation pressure (IP) were continuously monitored during administration of anaesthesia and recorded. After intubation (baseline T0); before $CO_2$insufflation induced pneumoperitoneum (PP) (T1); $CO_2$ PP insufflation (T2); 5 minutes after PP insufflation (T3); 10 minutes after PP insufflation (T4); 15 minutes after PP insufflation (T5); 20 minutes after PP insufflation (T6); 30 minutes after PP insufflation (T7), 60 minutes after PP insufflation (T8), and after desufflation (T9). Bradycardia and hypotension were recorded. Paracetamol IV 10 mg $kg^{-1}$ was applied for post-operative analgesia. p<0.05 wasconsidered significant.Results: HR, $rSPcO_2$, and $rSPcO_2$ decreased at all measured time intervals when compared to T0 (p<0.01) MAP decreased at T1 compared to T0 (p<0.001). Et-$CO_2$ increased at T3-T4-T5-T6 compared to T0 (p<0.001).Conclusion: We found that pneumoperitoneum reduced splanchnic oxygenation during laparoscopic abdominal surgery in paediatric patients, which was measured using NIRS
