Mild hypothermia for intracranial aneurysm surgery

Area of Science:

• Neurosurgery
• Clinical Medicine
• Medical Technology

Background:

• Study included 89 patients with intracranial aneurysms (Hunt-Hess score 1-3).
• Patients underwent surgery between 2003-2006 at the Department of Neurosurgery, University Hospital Brno.

Purpose of the Study:

• To evaluate the efficacy of managed hypothermia in improving neurological outcomes for intracranial aneurysm surgery.
• To assess the impact of therapeutic hypothermia on patient recovery and treatment results.

Main Methods:

• Patients were cooled to 34°C using circulating-water mattresses during cerebral vessel preparation.
• Cooling and rewarming rates were controlled (0.9°C/hr and 0.7°C/hr, respectively).
• Core body temperature was achieved in 100% of patients; esophageal and bladder temperatures showed no significant difference.

Main Results:

• Good neurological condition was achieved in 92% of patients (82 out of 89).
• Therapeutic hypothermia was successfully implemented in all cases.
• Compared to a previous cohort (1998-2002), good treatment results increased by 12% (p=0.0086).

Conclusions:

• Managed hypothermia significantly enhances neurological treatment results in intracranial aneurysm surgery.
• This neuroprotective strategy offers a statistically significant improvement in patient outcomes.
• The study demonstrates the successful application and benefit of therapeutic hypothermia in this patient population.
