Side Effects of Long-Term Continuous Intra-arterial Nimodipine Infusion in Patients with Severe Refractory Cerebral Vasospasm after Subarachnoid Hemorrhage.

Long-term CIAN therapy is associated with diverse side effects. The leading problems are an impairment of the hemodynamic situation and cardiac problems, an increase in infectious complications, a worsening of the motility of the gastrointestinal tract, and rising ICP values. Teams on neurointensive care units must be aware of these side effects to avoid that the beneficial effects of CIAN therapy on CV reported elsewhere are foiled by the problems this technique can be associated with.
