Magnesium sulfate did not affect vasospasm frequency after subarachnoid hemorrhage (SAH). However, it reduced patient morbidity and length of hospital stay, suggesting a favorable impact on recovery.
Area of Science:
- Neurosurgery
- Neurology
- Critical Care Medicine
Background:
- Subarachnoid hemorrhage (SAH) frequently leads to cerebral vasospasm, a serious complication.
- Current treatments for vasospasm yield suboptimal outcomes.
- Magnesium sulfate is being re-evaluated as an adjunctive therapy for vasospasm.
Purpose of the Study:
- To investigate the efficacy of magnesium sulfate as an adjuvant therapy in patients with SAH.
- To assess the impact of magnesium sulfate on vasospasm incidence and patient outcomes.
Main Methods:
- Seventy-two patients with SAH underwent microsurgical craniotomy.
- Patients were divided into two groups: one receiving standard care (nimodipine, hypervolemic therapy, hemodilution) and another receiving standard care plus magnesium sulfate infusion.
- Serum magnesium levels were maintained at approximately double normal values in the magnesium group.
Main Results:
- No significant difference in vasospasm incidence was observed between the groups.
- Patients receiving magnesium sulfate experienced a shorter hospitalization duration compared to the control group.
- No statistical differences were found in demographic or clinical admission grades between the groups.
Conclusions:
- Magnesium sulfate did not alter the frequency of vasospasm following SAH.
- Magnesium sulfate administration was associated with reduced morbidity and shorter hospital stays in SAH patients.
- Further research may clarify the role of magnesium in mitigating SAH complications.

Spasmolytic Agents: Chemical Classification
A major class of centrally acting spasmolytics is the α2-agonist, such as tizanidine. These drugs bind to α2-adrenoceptors, inhibiting the release of the excitatory neurotransmitter glutamate. They also promote...
