Abstract
Twelve patients with insufficient transcranial Doppler signal underwent transcranial color-coded ultrasonography before and after administration of SH U 508A with different modes of administration. Clinically useful enhancement time after bolus injection was surpassed by that after standard infusion (1 mL/min), whereas further prolongation was observed after individualized infusion. Intravenous infusion of SH U 508A provides a prolonged useful enhancement compared with that after bolus injection.
