Background and Aim: Maternal hypotension is the common complication encountered after subarachnoid block (SAB). This needs attention and treatment for the better maternal and foetal outcome. Administration of SAB with bolus dose of local anaesthetic produce faster onset and precipitate maternal hypotension. Injecting fractionated dose provides dense block and haemodynamic stability. Aim of this study was to compare fractionated and bolus dose of SAB in terms of haemodynamic stability and duration of analgesia.
