Summary
Cerebral ischemia during shoulder surgery in beach chair position is a severe complication linked to reduced cerebral perfusion pressure. Monitoring and preventing hypotension are crucial for patient safety.
Area of Science:
- Neurosurgery
- Anesthesiology
- Orthopedic Surgery
Background:
- Beach chair position during shoulder arthroscopy can lead to reduced cerebral perfusion pressure (CPP).
- General anesthesia combined with interscalene plexus block is commonly used in these procedures.
Observation:
- Three cases of cerebral ischemia during arthroscopic shoulder surgery in the beach chair position are reported.
- This complication, though rare, is severe and linked to decreased CPP.
Findings:
- Monitoring CPP by measuring arterial pressure and considering the hydrostatic gradient is essential.
- Preventive measures include correcting hypovolemia, managing hypotension, proper patient positioning, and avoiding deliberate hypotension.
Implications:
- Aggressive management of perioperative hypotension is critical.
- While non-invasive cerebral oxygenation monitoring is suggested, its clinical utility requires further study.
- This highlights the importance of vigilance and proactive management to prevent cerebral ischemia in this surgical setting.
