Anesthesia Management in Acute Stroke
Hemodynamic Management
- The American College of Cardiology recommends maintaining systolic blood pressure >100 mmHg or mean arterial pressure >80 mmHg to ensure adequate cerebral perfusion 1, 2
- If systolic blood pressure is >150 mmHg within the first 6 hours and immediate surgery is not planned, reduce blood pressure in a controlled manner 2, 3
- Avoid hypotension (systolic <110 mmHg) that can worsen secondary cerebral injury 3
- Use 0.9% saline solution as the crystalloid of choice for fluid resuscitation, as it is isotonic in terms of osmolality 1, 3
- Maintain euvolemia through repeated assessment of hemodynamic parameters 1
- Avoid hypotonic solutions such as Ringer's lactate, Ringer's acetate, and gelatins that can increase brain water content 3
Anesthesia Considerations
- The American Geriatrics Society suggests considering processed EEG monitors of anesthetic depth during general anesthesia in elderly patients to reduce postoperative delirium, although evidence is insufficient 4
- The American College of Cardiology recommends avoiding rapid bolus induction and using a slow induction rate of approximately 20 mg every 10 seconds until induction starts (0.5-1.5 mg/kg) 5, 6
- Choose anesthetic agents to maintain sinus rhythm and normotension 5, 6
- Implement invasive hemodynamic monitoring with a pulmonary artery catheter or transesophageal echocardiography for continuous optimization of loading conditions 5, 6
Alternative Anesthesia Techniques
- The American College of Cardiology recommends considering regional anesthesia when technically possible for the required procedure 5, 6
- Modify epidural or spinal interventions to avoid rapid changes in systolic blood pressure 5, 6
Situations that May Justify General Anesthesia
- The American College of Cardiology recommends considering general anesthesia for urgent surgical indications such as cerebellar hemorrhage with neurological deterioration or brainstem compression requiring surgical evacuation 3
- Significant mass effect, brainstem compression, or hydrocephalus requiring surgical intervention 3
- Patients with hemorrhagic shock requiring immediate bleeding control 3
