Abstract

Background: Supraclavicular block helps in achieving good anaesthesia along with complete muscle relaxation while providing hemodynamic stability and excellent post-operative analgesia. The addition of opioids to local anaesthetics injected during brachial plexus block has been shown to decrease the post-operative systemic analgesic requirements. This study was designed to compare the effectiveness of addition of MgSO (150 mg) and Fentanyl (50 micrograms) to 0.375% bupivacaine with placebo in supraclavicular brachial plexus block.
Materials and Methods: A prospective double-blind randomised controlled study was conducted comprising of 75 patients undergoing upper limb surgeries under ultrasound guided supraclavicular brachial plexus block. Patients were randomized into one of the three groups (n=25) and designated as Group P (20ml of 0.375% Bupivacaine only), Group M (150 mg Magnesium sulphate with Bupivacaine) and Group F (50 micrograms Fentanyl with Bupivacaine). The primary purpose of the studywasto compare the onset and quality of sensory as well as motor blockade in all three groups.
Results: The onset time (in minutes) of sensory as well as motor blockade was significantly shorter in group P (p<0> Conclusion: Although the additives delay the onset of action of local anaesthetic agents in brachial plexus block, Fentanyl as an adjuvant provided superior analgesia when compared to Magnesium sulphate as well as placebo with respect to duration of motor and sensory blockade. In addition, patients who received fentanyl as an adjuvant, required lesser rescue analgesia in the post-operative period.
