Clinical trials: Cerebral Perfusion Pressure
Cerebral Blood Flow, Cerebral Perfusion Pressure
Continous Assessment of Cerebral Autoregulation With Near-infrared Spectroscopy
Cerebral autoregulation can be explained by a tight coupling between oxygen supply and demand of the brain, and is essential to maintain a constant cerebral blood flow (CBF) in the context of changes in cerebral perfusion…

Hypotension (MeSH: D007022)
Carotid Artery Blood Flow, Blood Pressure, and Cardiac Output During Anesthesia in Children Aged 0-5 Years
Blood pressure is routinely monitored during anesthesia in children, but blood pressure alone may not accurately reflect blood flow to vital organs.

Increase in Intra-abdominal Pressure, Increase in Intracranial Pressure (ICP)
Changes in Cerebral Oxygenation Studies During Laparoscopy Procedure
The motivation results from the fact, that an intra-abdominal pressure is correlated with cerebral perfusion, in a mechanism of reducing venous outflow.
- Conditions
- Increase in Intra-abdominal Pressure, Increase in Intracranial Pressure (ICP), Laparoscopy, Cerebral Perfusion and Oxygenation
- Trial name
- NCT03640741
- Testing
- Laparoscopy
- Volunteers
- 17 people, healthy volunteers welcome
