Research Description

Dr. Gregory Liguori's research efforts are focused on two primary areas. The first is hemodynamic effects of regional anesthetics. Peripheral nerve blockade and neuraxial anesthetics can have significant hemodynamic effects on both healthy and cardio-vascularly compromised patients. Prevention of these events and treatment when necessary are essential to the conduct of safe and efficient anesthetics.

The second area of interest is on spinal anesthesia for ambulatory surgery. The local anesthetic mepivacaine is a novel alternative to other more common local anesthetics for ambulatory spinal anesthesia. We are investigating the efficacy of mepivacaine as a routine alternative in this setting.
