Clinical trials: Cerebral Perfusion and Oxygenation
Cerebral Perfusion, Cerebral Oxygenation
Evaluation of Cerebral Oxygenation During Orthopedic Surgeries Performed in the Beach Chair Position Under General Anesthesia
The goal of this observational study is to determine the correlation between cerebral oxygenation values measured by near-infrared spectroscopy (NIRS) and other routine monitoring parameters in patients placed in the semi-sitting…

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
