A novel CO2 insufflator, the turbine-based insufflator, has been developed to improve minimal invasive surgery. Turbine technology permits accurate pressure control resulting in an intra-abdominal volume that is dynamically adapted to ventilation. In addition, oscillometric measurements are performed to measure the abdominal compliance of the patient. This feasibility trial primarly aims to evaluate the technologic feasibility during pediatric laparoscopic surgery. Secondary outcomes are pressure stability, comparison of intra-abdominal pressure stability between the standard CO2 insufflator and turbine-based insufflator, and comparison of ventiliation pressures between these insufflators.
