    ObjectiveThis study investigated the influence of laparoscopic carbon dioxide (CO2) pneumoperitoneum on neonate circulation and respiration.MethodsThe study included neonates undergoing elective laparoscopic abdominal surgery. CO2 insufflation pressure was maintained within 8-14 mmHg for pneumoperitoneum creation. Heart rate (HR), mean arterial pressure (MAP), peripheral oxygen saturation (SpO2), partial pressure of end-tidal carbon dioxide (P ETCO2) and maximum inspiratory pressure were monitored continuously. Arterial blood samples were collected: 5 min before pneumoperitoneum creation (baseline); 5, 10, and 20 min after CO2 insufflation; 10 min after CO2 exsufflation; 10 min after surgery. pH, partial pressure of CO2 (PaCO2) and arterial oxygen saturation (SaO2) were also measured.ResultsThirty-six neonates were included. HR and MAP significantly increased after pneumoperitoneum creation, then decreased to baseline after CO2 exsufflation. PaCO2 and P ETCO2 were significantly higher after pneumoperitoneum creation, whereas pH was significantly lower 20 min after pneumoperitoneum creation compared with baseline. No significant differences were observed in SpO2 and SaO2.ConclusionCO2 pneumoperitoneum had a significant effect on neonatal circulation and respiration, suggesting that the pneumoperitoneal pressure should be limited within a certain range in neonates undergoing laparoscopic surgery.
