Why is it important?
Background: Brachial plexus block (BPB) is a well accepted technique to provide anaesthesia and analgesia for upper limb surgeries. Usage of ultrasound (USG) guided BPB technique has overcome the disadvantages caused by traditional landmark technique. Objective: To determine the block performance time, onset time, success rate, and any complications with the USG guided technique in both Axillary and Infraclavicular BPB Methods: For an ultrasound guided brachial plexus block 80 patients undergoing elective upper limb surgeries were randomly allocated into 2 groups group AX (axillary), Group IC (infraclavicular) to receive Ropivacaine 0.75% 25 ml. Block performance time, onset and duration of sensory and motor block and success rate were assessed. Results: The mean block performance time of Group IC (6.43 ± 0.38) was significantly shorter compared to Group AX (8.46 ± 0.43). The mean onset time of sensory block (5.33 ± 1.67 vs 7.03 ± 2.01) and motor block (9.23 ± 3.01 vs 17.53 ± 4.10) were significantly faster in Group IC compared to Group AX. Duration of sensory block (290.38 ± 78.65 vs 295.25 ± 35.86) and motor block (356 ± 97.99 vs 357.8 ± 108.13). Success rate was (95%) in group IC and (85%) in group AX. Conclusion: Ultrasound guided BPB through infraclavicular approach has shorter performance time, higher success rate and faster onset of sensory and motor block when compared to axillary approach. There was no statistically significant difference in duration of sensory and motor block in both approaches.
