Continuous autonomic system monitoring during neurosurgical procedures –proof of concept
Authors' conclusion
Autonomic system monitoring during neurosurgical procedures is safe and feasible.
Study context
- Population
- Consecutive patients undergoing neurosurgery for intracranial pathologies54.3% male
- Participants
- 129 patients
- Outcome
- Feasibility and stability of continuous autonomic nervous system (heart rate variability (HRV), BRS) monitoring during surgery
Methodological detailsproof-of-concept, consecutive patients, HR and mean arterial pressure (MAP) continuously monitored during routine anaesthesia care, recorded via ICM + software; four intraoperative episodes defined per patient
- Proof-of-concept
- Consecutive patients
- HR and MAP continuously monitored during routine anaesthesia care, recorded via ICM + software; four intraoperative episodes defined per patient
Main finding
As reported in the abstract
ANS parameters during intracranial surgery
- Baroreflex-sensitivity (BRS) continuously decreased during cranial surgery, indicating stabilized autonomic function
- BP variability increased during semi-sitting surgery
- Autonomic nervous system (ANS) monitoring during neurosurgery safe and feasible
Observational data: associations, not effects.
