Differential blockade by central neuraxial blockade is achieved by-
Correct Answer: Epidural Anaesthesia
Description: Spinal anaesthesia is used for Intraoperative anaesthesia only. Epidural used both for Intraoperative anaesthesia and post operative analgesia by decreasing the concentration of local anaesthetics. Depending on the level of anaesthesia required epidural catheter is put. Drug is put according to the required number of segment to be blocked. Differential block is achieved by only epidural . Different concentrations are used for blocking different nerve fibres. A differential block refers to the clinical phenomenon that nerve fibers with different functions have different sensitivities to local anesthetic blockade. This is well proven in both neuraxial and peripheral nerve blocks.
