About this trial
A novel CO2 insufflator, the Turbine-based insufflator, has been developed to improve minimally 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 the Turbine-based insufflator, and comparison of ventiliation pressures between these insufflators.

Treatments tested in this trial
Turbine-based insufflator
DeviceUse of the Tubine-based insufflator during surgical procedure.
Treatment groups
Trial outcomes
Primary outcomes
The number of adverse device events as assessed by observations during the procedure (qualitative measurements)
Observations of researcher and surgeon (number of adverse device events)
Secondary outcomes
Assessment of intra-abdominal pressure stability, assessed by the median and interquartile range of the actual measured pressure
Recording the intra-abdominal pressure with a pressure line during the surgical procedure. Assessment of the difference between the actual measured pressure and the target pressure. Stability is defined as the median pressure with the interquartile range.
Registration of events that impair intra-abdominal pressure stability (observationa, qualitative)
Comparison of intra-abdominal pressure stability and ventilation pressures between conventional insufflation and turbine-based insufflation by comparing median, minimum, and maximum pressures.
Between turbine-based insufflation and conventional insufflation.
Abdominal compliance by performing endoscopic oscillometry in a pediatric population (using insufflation pressure and flow for calculating the abdominal compliance; quantitative measurements)
Intra-abdominal pressure and intra-abdominal flow data recording during surgical procedure.
