To Compare the Efficacy of Dexamethasone Versus Ketorolac with Ropivacaine for Nerve Stimulator Guided Infraclavicular Brachial Plexus Block: A Prospective Randomised Comparative Study
Introduction: Infraclavicular Brachial plexus block is an advanced regional anaesthetic technique well suited for hand and fore arm surgeries. The aim of the study is to determine the efficiency of Ropivacaine with Ketorolac for infraclavicular Brachial plexus block for hand and fore arm surgeries.
Methodology: 50 ASA grade I and II patients, aged between 18–58 years. of both sexes were randomly allocated into two groups equally of D and K. Group D were assigned to receive Infraclavicular Brachial plexus block under nerve stimulator guided technique with 0.5% Ropivacaine 28 ml+Dexamethasone 2 ml (8 mg) [total volume of 30 cc] Group K were assigned to receive Infraclavicular Brachial plexus block with 0.5% Ropivacaine 28 ml+Ketorolac 2 ml (60 mg) [total volume of 30 cc].
Results: The mean duration of sensory and motor block was significantly prolonged in group D compared to group K,10.5 vs. 9.3 hours for sensory block and 8.5 vs. 6.40 hours for motor block, p<0.05. The mean time to first request analgesia was significantly prolonged in group D compared to group K, 17.40 hours, 12.40 hours respectively.
Conclusions: Ropivacaine with dexamethasone combination produced profound analgesia and prolonged postoperative analgesia when compared to Ropivacaine with ketorolac.
