“…In our study, the onset of sensory and motor block was significantly faster in the double-point injection technique. Tran et al [13] had similar results, while Sayed et al [14] and Choi et al [8] did not find any difference. In addition, the double-point injection technique significantly prolonged the total duration of sensory and motor block.…”

“…There have been studies[131415] where double-point injection technique has been used for ultrasound-guided supraclavicular block. However they studied limited parameters in the two approaches, unlike our study where we tried to include all the relevant parameters.…”

“…The reason for longer duration of block could be an even distribution and systemic absorption of the local anesthetic solution. Sayed et al [14] found no difference in the total duration of sensory and motor block.…”

“…There was no complication in either of the two groups. Sayed et al [14] and Roy et al [16] found higher incidence of paresthesia with double-point injection technique. In our methodology we included the technique of hydrodissection that prevents the needle tip from injuring either the plexus or vessel.…”

Background and Aims:This study aims to compare the single-point injection and double-point injection technique of ultrasound-guided supraclavicular block with regard to the success rate, time taken to perform the procedure, onset and duration of sensory and motor block, and complications.Material and Methods:A total of 60 American Society of Anesthesiologists physical status I and II patients between 20 and 50 years of age, with body mass index ≤30 kg/m2 posted for forearm surgeries, with anticipated surgical duration more than 1 h were randomly divided into two groups: group S (single-point injection) and group D (double-point injection technique). After locating the brachial plexus with ultrasound, needle was inserted from lateral to medial direction to reach the plexus. In group D, 20 ml of inj. bupivacaine 0.5% was deposited as 10 ml each in superior (in the cluster) and inferior pocket (corner pocket) between the plexus and subclavian artery with the help of hydrodissection while in group S the total 20 ml was deposited in the superior (in the cluster) pocket. The onset of sensory and motor block was assessed using pin prick method and modified Bromage scale. Adequacy of block was ensured by assessing the ulnar, radial, and median nerve distribution. Procedural time was defined from the point of scanning the plexus till the drug was injected completely. Total sensory, motor duration, and complications if any were noted.Results:Group D had higher success rate compared to group S (96.7 vs. 83.3%; P < 0.0001). The total procedural time was significantly more in group D compared to group S (14.6 ± 2.7 vs. 10.1 ± 1.7 min; P < 0.0001). The onset of sensory and motor block was faster and the duration of sensory and motor block was significantly longer in group D.Conclusion:The adequacy of block, sensory, and motor duration was significantly high in newer double-point injection technique. However, it requires longer procedural time compared to single-point injection technique.

Comparison between Single- and Double-Injection Technique for Ultrasound-Guided Supraclavicular Block: A Randomized Controlled Study

Background: The supraclavicular approach to brachial plexus block is a commonly employed regional anesthesia technique for providing surgical anesthesia and postoperative analgesia for patients undergoing upper limb fractures. With ultrasound (US) guidance, the success rate of the block is increased, and complications like pneumothorax and vascular puncture are minimized. The block can be performed using single injection at the corner pocket or double injection, that is, half of the drug at the corner pocket and the remaining half at the cluster of brachial plexus divisions. Methods: After institutional ethics committee approval, we randomized 40 patients scheduled with fractures for elective upper extremity surgery under US-guided supraclavicular brachial plexus block. Twenty patients received 30 mL of local anesthetic at the corner pocket (group SI), and 20 patients received 30 mL of local anesthetic using the dual-injection technique in divided doses (group DI). Demographic data, time to block performance, time to sensory and motor block, total anesthesia-related time (TART), block success, and failure were compared between both groups. Results: The demographic data were comparable between both groups. The DI group had a significantly faster onset than the SI group (p = 0.0172). There was a statistically significant lesser performance time in group SI than in group DI (p < 0.034). The sensory and motor block achieved was comparable between both groups. Conclusion: The success rates in both the SI and DI techniques are comparable. The DI technique results in a faster onset and hence a shorter TART; however, it may not be clinically relevant.
