Subarachnoid Anaesthesia for Elective Caesarean Section A Comparison of Two Hyperbaric Solutions

Abstract

Forty parturients scheduled for elective cesarean section were randomly divided into 2 groups of 20 each and given spinal anesthesia with either 2.5 ml of 0.5% bupivacaine in 8% dextrose or 2.0 ml of 0.5% dibucaine (Cinchocaine) in 6% dextrose. Usual fluid preloading preceded the subarachnoid tap with a 26-gauge needle and the patient was then turned supine with left lateral tilt. Assessment was made of changes in maternal heart rate and blood pressure, onset, duration and extent of sensory and motor blockade, adequacy of anesthesia for surgery, and neonatal condition at birth. The assessor was not aware of the solution employed.
