A comparative study between conventional and ultrasound-guided supraclavicular brachial plexus block in upper limb surgeries

Background: The well-researched method of brachial plexus blocking is used in upper limb procedures. The blind paresthesia methodology used in the conventional approach has a greater failure rate and may cause damage to the tissues that surround and nerves. Peripheral nerve stimulators and ultrasound methods were used to better localise the nerve/plexus in order to prevent certain of these issues. Methods: A total of 50 patients were included in this prospective randomized trial and randomly assigned to two groups: US (Group US) and LM (Group LM) after receiving clearance from the institutional ethics committee and consent from the patients. Each of the two groups got 0.5% bupivacaine. The injection of local anaesthetic (bupivacaine, 2 mg/kg) did not exceed the hazardous dosage since the amount was determined based on body weight. Result: The demographic information for both groups was similar. When compared to ultrasound, the mean time required for the method to provide a block via inducing paraesthesia was much shorter. There was no statistically significant difference in the meantime of motor block start, sensory blockade, or the length of both types of blockades. The ultrasonic group had a higher block success rate than the traditional group, although this difference didn't prove clinically important. Conclusions: The most secure and effective approach to perform a supraclavicular brachial plexus block is using ultrasound guidance. Because ultrasonography allows for the transmission of local anaesthetic and instantaneous imaging of underlying structures, the incidence of problems is lower.
