Comparison of spinal block characteristics on height and weight based dosage versus fixed dosage of intrathecal bupivacaine for elective caesarean section

Spinal anaesthesia is a standard procedure for the conduct of elective and emergency caesarean section. Spinal block induced sympathetic blockade is often associated with incidence of maternal hypotension. Various measures to limit sympathetic blockade has been documented. This prospective double-blind study evaluated the spinal block achieved with height and weight adjusted dose versus fixed dose of bupivacaine with fentanyl.
