title: [Cardiovascular and respiratory changes during laparoscopy in neonates and infants].
abstract: The pneumoperitoneum induced during laparoscopy has cardiovascular and respiratory effects that have to be taken into account to perform laparoscopic procedures in neonates and small infants. The aim of this paper is to describe the hemodynamic and ventilatory changes that occur in a group of these patients undergoing standard laparoscopic procedure. We performed a retrospective review of patients undergoing laparoscopic pyloromyotomy in our institution. We collected demographic data, data from the intervention, outcome and complications and hemodynamic parameters (heart rate--HR--and blood pressure--BP--) and respiratory (O2 saturation--SO2--and exhaled CO2--ECO2--) at different times during surgery. We performed statistical analysis of these data. We reviewed a total of 55 charts. Mean age was 34 days and average weight 3,785 g. All patients were ventilated with pressure control mode and received maintenance fluid therapy. BP, HR and SO2 were stable throughout the surgery not showing significant differences. The ECO2 increased significantly after inflation, however it was controlled by increasig respiratory rate. In conclusion, the hemodynamic and ventilatory response in these patients is controllable with anesthetic and surgical measures but it is important to consider the possible consequences of pneumoperitoneum in this group of patients.
