Comparison of Intravenous Colloid and Colloid-Crystalloid Combination in Hypotention Prophylaxis during Spinal Anesthesia for Cesarean Section

CONTEXT: Many studies comparing different intravenous fluid types usually do not use equipotent volumes of three to one crystalloid to colloid ratio. AIM: This study was designed to compare the efficacy of equipotent volumes of colloid and crystalloid-colloid combination in spinal anesthesia-induced hypotension prophylaxis during cesarean section. MATERIALS AND METHODS: pregnant women scheduled for elective cesarean section were prospectively randomized into two groups to receive either 1000ml of crystalloid/colloid (750/250ml) combination or 500ml colloid intravenous fluid preload, before spinal anesthesia. hemodynamic variables were monitored till the end of surgery.
