Background and Aims: The most effective approach for infraclavicular brachial plexus block in adults is to target the posterior cord, usually situated posterior to axillary artery. However, we do not know if this can be extrapolated in children. Our primary objective was to compare the clinical success rate of ultrasound guided infraclavicular brachial plexus block in children with local anesthetic injection aimed at two targets. These were posterior to axillary artery (posterior cord) and lateral to axillary artery (lateral cord). The secondary objectives involved need for intraoperative rescue analgesia, evaluation of duration of analgesia, incidence of complications such as pneumothorax and arterial puncture, comparison of postoperative pain scores and fluoroscopic dye spread pattern was also observed. Material and Methods: It was a randomized, prospective pilot study. Forty children undergoing forearm and hand surgeries were randomized to two groups, in accordance with the target site of the block. Target sites of Group P (20 patients) and Group L (20 patients) were posterior and lateral to the axillary artery, i.e., posterior and lateral cord respectively. Aforesaid objectives were assessed. SPSS (Version 15.0) statistical package was used. Comparison between Group L and P was by using student’s unpaired t test for age and weight. Fisher’s exact probability test was applied to compare percentages between groups. Results: Blocks of both groups were equally successful. No patient required intraoperative rescue analgesia. Duration of analgesia was comparable. Both groups had no major complications and similar postoperative pain scores. Conclusions: The success rate of infraclavicular brachial plexus block by aiming at the lateral and posterior cord was similar.
