Comparing noradrenaline and phenylephrine effects on blood flow during brain surgery
Official title: Vasopressor Impact on Brain Circulation, Organ Blood Flow and Tissue Oxygenation During Anesthesia in Neurosurgical Patients
Run by University of Aarhus · NCT06083948 · Data updated 2026-11-12
This study is testing whether noradrenaline or phenylephrine is better at keeping blood flow and oxygen levels stable during brain surgery for people with brain tumors.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 to 75 with diagnosed supratentorial brain tumors scheduled for elective craniotomy.
✕Probably not a fit
Patients with severe ASA physical status (IV-VI), those with allergies to the study medications, or those who are pregnant or breastfeeding may not benefit from this study.

What this trial studies
This clinical trial aims to determine the optimal vasopressor for maintaining organ blood flow and tissue oxygen delivery during neurosurgery in patients with brain tumors. It involves a randomized, double-blinded design where participants will receive either noradrenaline or phenylephrine infusion. The study will utilize PET scans to measure blood flow and oxygen consumption in the brain and other vital organs before surgery. A total of 32 patients aged 18 to 75 with diagnosed brain tumors will be enrolled for this investigation.
Why it matters
Potential benefit: If successful, this study could identify the most effective vasopressor to enhance organ perfusion and oxygenation during neurosurgery, potentially improving patient outcomes.
How similar studies have gone: Previous studies have explored vasopressor effects in surgical settings, but this specific comparison of noradrenaline and phenylephrine in neurosurgery is novel.
