Principles of neuroanesthesia in stroke surgery

Area of Science:

• Neurology
• Anesthesiology
• Critical Care Medicine

Background:

• Subarachnoid hemorrhage (SAH) is a critical neurological condition associated with high morbidity and mortality.
• SAH presents with diverse symptoms and systemic complications, including cardiac arrhythmias and pulmonary edema.
• Effective management necessitates preventing rebleeding and treating delayed cerebral ischemia.

Purpose of the Study:

• To review the fundamental principles of neuroanesthesia for patients diagnosed with subarachnoid hemorrhage.
• To emphasize the importance of understanding cerebral hemodynamics in perioperative care for SAH.

Main Methods:

• Review of current literature and established guidelines on neuroanesthesia for SAH.
• Discussion of the physiological effects of SAH on cerebral hemodynamics.
• Analysis of the impact of various anesthetic agents and systemic conditions on SAH patients.

Main Results:

• Perioperative treatment success depends on comprehensive knowledge of cerebral hemodynamics.
• Anesthetic agents can significantly influence cerebral blood flow and intracranial pressure in SAH.
• Understanding drug interactions and patient-specific factors is crucial for optimizing outcomes.

Conclusions:

• Neuroanesthesia for SAH requires a deep understanding of cerebrovascular regulation and the effects of anesthetic interventions.
• Optimal perioperative management integrates surgical/endovascular techniques with precise anesthetic strategies.
• This review provides essential principles for clinicians managing SAH patients under anesthesia.
