Efficacy of Equal Volume of Ringer Lactate Versus 3.5% Polymer of Degraded Gelatine Solution (Haemaccel) as Preloading Fluid for Prevention of Hypotension after Spinal Anaesthesia for Lower Segment Cesarean Section

Introduction: Systemic hypotension is frequently and immediately seen after spinal anaesthesia. Historically Ringer lactate is used to substitute the acute relative volume loss after spinal anesthesia, although it remains in intravenous circulation for a short period. The preloading with 5% albumin and gelatine have become popular and effective as they remain intravascular for a longer duration providing sustained normotension. The aim of this study was to assess the efficacy of equal volume of Ringer lactate and Haemaccel as a preloading fluid for the prevention of hypotension after spinal anaesthesia in patients undergoing Lower Segment Cesarean Section.
