About the trial
What the trial wants to find out
This prospective observational study aims to evaluate the effectiveness of Near-Infrared Spectroscopy (NIRS) and Bispectral Index (BIS) monitoring during endovascular coil embolization of cerebral aneurysms under general anesthesia. Changes in regional cerebral oxygen saturation (rSO₂) measured by NIRS will be assessed in relation to BIS values and hemodynamic parameters throughout the procedure.
Read full original descriptionShow less
The frequency, duration, and severity of cerebral desaturation episodes detected by NIRS, as well as their association with anesthetic depth and hemodynamic fluctuations, will be analyzed. The study does not involve any additional intervention beyond routine clinical monitoring.
The group in the trial
- Cerebral Aneurysm Patients Undergoing Coil Embolization
Adult patients undergoing endovascular coil embolization for cerebral aneurysm under general anesthesia. Near-infrared spectroscopy (NIRS) and bispectral index (BIS) monitoring are performed as part of routine clinical anesthesia care, and intraoperative neuromonitoring and hemodynamic data are recorded observationally without any additional intervention.
Treatment: Near-Infrared Spectroscopy (NIRS) and Bispectral Index (BIS) Monitoring
