Summary

Despite many regional anesthetic techniques have been described for anesthesia of the brachial plexus which is responsible for the sensory and motor innervation of entire upper limb, still, supraclavicular block (SCB) is the regional anesthetic technique of choice.

SCB has been described as the spinal anesthesia of the upper limb as it offers dense anesthesia of the brachial plexus for the surgical procedures below the arm from elbow to hand. Although the SCB has a high incidence of complications like pneumothorax, the use of ultrasound-guided block improved the safety for the patient. There are several adjuvants have been added to SCB aiming for prolongation of the duration of peripheral nerve block as fentanyl, alpha 2 adrenergic agonist (Dexmedetomidine, Clonidine), tramadol, ketorolac and Magnesium sulfate.

Magnesium has anti-nociceptive effects in animal and human models, principally related to blocking the N-methyl-D-aspartate (NMDA) receptors and regulation of calcium influx into cells. Calcium influx leads to a sequence of central sensitization such as windup phenomenon and long term potentiation which are crucial mechanisms that determine the duration and intensity of post-operative pain. Magnesium prevents central sensitization triggered by peripheral nociceptive stimulation in response to painful stimuli.

Non-Steroidal Anti-Inflammatory drugs (NSAID) inhibit synthesis of prostaglandins from arachnoid acid in phospholipid membranes resulting in decreased afferent nociceptive signals from the site of surgery. There are a lot of studies supported the analgesic effect when NSAIDs are concentrated at a peripheral site compared to the systemic administration therapy. Ketorolac is a parenteral NSAIDs. Studies have shown that ketorolac as an adjuvant to local anesthetics during peripheral nerve block enhanced duration and quality of analgesia.
