Pediatric laparoscopy and adaptive oxygenation and hemodynamic changes.

Adaptive changes in oxygenation and hemodynamics are evaluated during pediatric laparoscopy. The children underwent laparoscopy (LAP Group, n=20) or open surgery (Open Group, n=10). Regional cerebral (rScO₂) and peripheral oxygen saturation (SpO₂), heart rate (HR), diastolic (DP) and systolic pressure (SP) were monitored at different intervals: basal (T0); anesthesia induction (T1); CO₂PP insufflation (T2); surgery (T3); CO₂PP cessation (T4); before extubation (T5). At T1, in both the LAP and Open groups significant changes in rScO₂, DP and SP were recorded compared with T0; a decrease in SatO₂ was also observed at T5. In the LAP group, at T2, changes in HR related to CO₂PP pressure and in DP and SP related to IAP were noted; at T4, a SP change associated with CO₂PP desufflation was recorded. Open group, at T3 and T5 showed lower rScO₂ values compared with T1. Pneuperitoneum and anesthesia are influent to induce hemodynamics changes during laparoscopy. [ABSTRACT FROM AUTHOR]
