However, the creation of pneumoperitoneum with carbon dioxide (CO₂) insufflation and the use of the Trendelenburg position may increase intra-abdominal pressure and potentially influence intracranial pressure and cerebral hemodynamics. These physiological changes may affect cerebral perfusion and oxygenation during surgery.\n\nThis prospective observational study aims to evaluate cerebral hemodynamic changes during pediatric laparoscopic inguinal hernia repair using transcranial Doppler ultrasonography (TCD) and near-infrared spectroscopy (NIRS). Middle cerebral artery (MCA) flow velocities and pulsatility index (PI) will be measured with TCD as indirect indicators of intracranial pressure, and their relationship with cerebral oxygen saturation measured by NIRS will be assessed. In addition, mean arterial pressure and end-tidal CO₂ values will be recorded to evaluate their association with cerebral hemodynamic changes during different phases of surgery.",[60,61,62],"Cerebral Perfusion Pressure","Trendelenburg","Pediatric",[64,65,66,67,68],"transcranial doppler usg","cerebral perfusion","trendelenburg","nırs","pediatric","NOT_YET_RECRUITING","2026-03-15",{"date":72,"type":73},"2026-03-19","ACTUAL",{"date":75,"type":55},"2026-03-16",{"date":77,"type":55},"2027-04-01",{"name":14,"class":6},1]
