    Area of Science:

    • Neurosurgery
    • Anesthesiology
    • Vascular Surgery

    Background:

    • Intracranial aneurysms pose significant surgical risks.
    • Reducing operative mortality and morbidity is a key goal in aneurysm surgery.
    • Preoperative management includes bedrest, steroids, and medications to prevent rebleeding.

    Purpose of the Study:

    • To evaluate the safety and efficacy of controlled hypotension as an anesthetic technique for intracranial aneurysm surgery.
    • To assess the impact of controlled hypotension on operative mortality and neurological deficits.

    Main Methods:

    • Retrospective analysis of 62 intracranial aneurysm surgeries over five years.
    • Detailed anesthetic management for 14 patients, including halothane-nitrous oxide-oxygen endotracheal anesthesia with controlled ventilation.

  • Utilized adjuncts such as osmotic diuresis, CSF drainage, head-up tilt, and trimethaphan (Arfonad) for controlled hypotension.

    • Main Results:

    • Overall mortality for 62 patients was 4.8%.
    • No operative deaths occurred in the 14 patients managed with controlled hypotension.
    • One patient died postoperatively, and three experienced neurological deficits.

    Conclusions:

    • Controlled hypotension is a safe and effective anesthetic technique for intracranial aneurysm surgery.
    • Proper application of controlled hypotension can significantly reduce anesthesia-related risks.
    • This technique contributes to improved outcomes in complex neurosurgical procedures.
