Spinal anesthesia provides a fast, profound, and symmetrical sensory and motor block of high quality in patients undergoing cesarean delivery (1, 2). The most common serious adverse effect of spinal anesthesia for cesarean delivery is hypotension, with a reported incidence greater than 80% (3).
A number of strategies for preventing hypotension have been investigated, because it may have detrimental maternal and neonatal effects. The use of lateral uterine displacement is routine procedure to prevent hypotension (4). Other strategies have included the use of intravenous fluid preload, gravity (Trendelenburg or leg rising), compression devices on the legs, and prophylactic vasopressors (1). However, no methods have proved satisfactory. Ephedrine
