Abstract
Background: Spinal induced maternal hypotension is a common problem during cesarean delivery. Timing of infusion of crystalloid may be important because of its short stay in intravascular space. Aim: This study was conducted to compare effectiveness of preloading and co-loading with crystalloid in prevention of spinal anesthesia induced maternal hypotension during caesarean section. Material and Methods: In total 62 parturients were randomized to two groups. Preload group (Group P) received 15 ml/kg of Ringer Lactate solution over 20 min before giving low dose (2 ml, 0.5% hyperbaric Bupivacaine) spinal anesthesia and coload group (Group C) were given same volume of Ringer Lactate solution as fast as possible after CSF tapping and Bupivacaine injected. Non-invasive BP measurements were recorded. The incidence of hypotension and dose of inj. Mephentermine were checked. Blood pressure, heart rate, nausea and neonatal outcome were assessed. Results: The incidence of hypotension, blood pressure drop and dose of Mephentermine was lower in the coload group compared to the preload group (significant p<0.05). The incidence of nausea was also lower in the coload group. No significant differences in neonatal outcome. Arpit Singhal, Ashima Gupta, S.P. Chittora.
