Randomized Controlled Trial Clinical TrialHaemodynamic effects of subarachnoid blockade: 20% lignocaine versus 0.5% plain bupivacaine.
Our study compared the haemodynamic changes after spinal anaesthesia with 2% lignocaine and 0.5% plain bupivacaine. ⋯ In patients developing a sensory block at or above the T6 dermatome, the decrease in cardiac output and mean arterial pressure in the first 25 min. after spinal anaesthesia is smaller if 2% lignocaine rather than 0.5% bupivacaine is used for blockade.
