Background and aims
Costoclavicular brachial plexus block is gaining popularity due to its ease of application. Lateral and medial costoclavicular approaches have recently been defined. In the current study, we aimed to investigate the procedural execution of these approaches in the pediatric population.
Methods
In this study 55 children aged between 2 and 10 years were randomized to receive lateral (LC group) or medial (MC group) costoclavicular brachial plexus block after induction of general anesthesia for postoperative analgesia. All patients received bupivacaine (1 mg/kg, 0.25%) within the center of the cord cluster. The number of needle maneuvers was recorded as primary outcome. Block performing features (ideal ultrasound-guided brachial plexus cords visualization, needle pathway planning time, needle tip and shaft visualization difficulty, requirement of extra needle maneuver due to insufficient local anesthetic distribution, block performance time, total procedure difficulty) and postoperative pain-related data (block intensities, pain scores and analgesic requirements) were all compared as secondary outcomes.
Results
The LC group patients required less ultrasound visualization time (median 14 s, range 11–23 s vs. median 42 s, range 15–67 s, p < 0.001) and fewer needle maneuvers (median 1, range 1–2 vs. median 3, range 2–4, p < 0.001) compared to the MC group. Similarly, the median block performance duration was shorter (median 67 s, range 47–94 s vs. median 140s, 90–204 s, p < 0.01) and procedures were perceived as easier (median 4, range 4–5 vs. median 3, range 2–5, p = 0.04) in the LC group. All other parameters were comparable (p > 0.05).
Conclusion
The lateral approach required less needle maneuvers than the medial approach. Both techniques represented a good safety profile with favorable analgesic features.
