[Urapidil: hypotension induced in neuroanesthesia]. / Urapidil: ipotensione indotta in neuroanestesia.

The authors report their experience on the use of urapidil in 31 patients, submitted to neurosurgical procedures. Urapidil, administered both in the inductive (0.7-1 mg/kg) and in preoperative phases (0.6-0.8 mg/kg/h), produced a MAP decrease of about 25% without significant variations in cardiac frequency or of other monitored parameters.
