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.",[26,27,28],"Cerebral Perfusion Pressure","Trendelenburg","Pediatric",[30,31,32,33,34],"transcranial doppler usg","cerebral perfusion","trendelenburg","nırs","pediatric","NOT_YET_RECRUITING","2026-03-15",{"date":38,"type":39},"2026-03-19","ACTUAL",{"date":41,"type":21},"2026-03-16",{"date":43,"type":21},"2027-04-01",{"name":45,"class":46},"Hanife Kabukcu","OTHER",1,{"id":49,"slug":50,"hasResults":11,"nctId":51,"briefTitle":52,"officialTitle":52,"acronym":4,"eligibilityCriteria":53,"healthyVolunteers":11,"sex":54,"minAge":55,"maxAge":56,"enrollmentInfo":57,"targetDuration":22,"studyType":23,"phases":4,"briefSummary":59,"conditions":60,"keywords":61,"overallStatus":35,"whyStopped":4,"lastUpdateSubmitDate":70,"lastUpdatePostDateStruct":71,"startDateStruct":73,"completionDateStruct":75,"leadSponsor":77,"locationsCount":47},"100617333","evaluation-of-cerebral-perfusion-in-supine-and-steep-trendelenburg-positions-during-robotic-prostatectomy-100617333","NCT07317258","Evaluation of Cerebral Perfusion in Supine and Steep Trendelenburg Positions During Robotic Prostatectomy","Inclusion Criteria:\n\nMale patients aged 18 to 80 years\n\nASA physical status I-III\n\nScheduled for robotic prostate surgery under general anesthesia\n\nAble and willing to provide written informed consent\n\nExclusion Criteria:\n\nDecline or inability to provide informed consent\n\nAge \\\u003C18 years or \\>80 years\n\nInability to perform ultrasonographic measurements or to maintain the required surgical position\n\nPresence of intracranial space-occupying lesions\n\nHistory of cerebrovascular accident (CVA) or carotid artery occlusion\n\nKnown neurological disorders (e.g., epilepsy)","MALE","18 Years","80 Years",{"count":58,"type":21},60,"Evaluation of Cerebral Perfusion in Supine and Steep Trendelenburg Positions During Robotic Prostatectomy Robotic endoscopic radical prostatectomy requires pneumoperitoneum and the steep Trendelenburg position to ensure optimal surgical visualization.

Cerebral blood flow velocity in the middle cerebral artery and pulsatility index (PI) were measured to estimate ICP, while NIRS was used to assess cerebral oxygen saturation.\n\nAdditionally, arterial blood gas parameters (PCO₂, PO₂, Hb), end-tidal CO₂, and mean arterial pressure (MAP) were recorded.
