Blood Pressure Management in Spinal Cord Stroke

Critical Blood Pressure Management Targets

The American Association of Neurological Surgeons/Congress of Neurological Surgeons recommends maintaining mean arterial pressure (MAP) > 85 mmHg continuously for 5-7 days post-injury to optimize spinal cord perfusion and neurological outcomes, with limited evidence base from prospective studies without control groups 1, 2, 3, 4
Systolic blood pressure must remain > 110 mmHg before injury assessment to reduce mortality, according to guidelines from Anaesthesia 4, 5, 2
Avoid any episodes of systolic BP < 90 mmHg through day 5-7, as hypotension at admission is an independent mortality predictor, as suggested by Anaesthesia 4, 5
French guidelines suggest a more conservative MAP > 70 mmHg may be sufficient, noting insufficient evidence for higher targets, as mentioned in Anaesthesia and Praxis Medical Insights 4, 1

Use continuous arterial catheter monitoring because MAP falls below target approximately 25% of the time without invasive monitoring, as recommended by Anaesthesia and Praxis Medical Insights 4, 1, 2
The correlation between MAP and neurological improvement is strongest in the first 2-3 days after injury, according to Anaesthesia and Praxis Medical Insights 4, 1, 2

Administer fluids first before initiating vasopressors in patients without contraindications, as suggested by Praxis Medical Insights 2, 3
Treat prolonged significant BP decreases immediately to prevent secondary ischemic injury, as recommended by Praxis Medical Insights 2
