Hemodynamic response during aneurysm clipping surgery among experienced neurosurgeons

Area of Science:

• Neurosurgery
• Cardiovascular Physiology
• Surgical Stress Response

Background:

• Neurosurgery is a high-stress profession.
• Understanding surgeon stress is crucial for patient safety and well-being.

Purpose of the Study:

• To investigate the hemodynamic responses of experienced neurosurgeons during aneurysm clipping surgery.
• To determine if these responses correlate with patient clinical status.

Main Methods:

• Studied 4 experienced neurosurgeons during 42 aneurysm clipping procedures.
• Monitored blood pressure (BP) and heart rate (HR) at rest and during 7 surgical phases.
• Analyzed data for associations with aneurysm characteristics and patient outcomes.

Main Results:

• Neurosurgeons showed significantly elevated HR and BP during surgery compared to rest.
• Peak HR occurred post-clipping; peak BP occurred post-neck dissection.
• No significant association found between surgeon hemodynamics and aneurysm rupture status, location, or patient clinical scores (WFNS, GCS, Fisher grade).

Conclusions:

• Aneurysm clipping surgery induces significant hemodynamic activation in experienced neurosurgeons.
• Surgeon's hemodynamic response is not linked to aneurysm location or patient's clinical condition.
• Further research may explore stress mitigation strategies for neurosurgeons.
