    Abstract:
    BACKGROUND: It is aimed to compare the block onset times and performance features of costoclavicular techniques (medial and lateral approach) versus lateral sagittal technique. METHODS: Patients were randomized into three groups. For costoclavicular techniques, ultrasound probe was placed parallel to clavicle obtaining nerve cords, axillary artery and axillary vein visual from lateral-to-medial, respectively. The block needle was advanced from lateral (Group CLB) or medial (Group CMB) to perform costoclavicular block. For lateral sagittal technique (Group LSB), ultrasound probe was placed sagittal and perpendicular below the coracoid process to obtain sagittal artery image with the cords around. Total 20 ml of 0.5% bupivacaine and 10 ml of 2% lidocaine were deposited for all groups. Sensory and motor block onset times, block performance properties, complications, and patient/surgeon satisfactions were investigated. RESULTS: Among 56 patients, the primary outcome, sensory block onset time was shorter in Group CLB than Group CMB and Group LSB (10 [5-15], 10 [10-20], and 15 [10-15] minutes, respectively, p < 0.05). Motor block onset was also fastest in Group CLB (15 [10-20] mins for CLB, 20 [15-20] mins for LSB, and 22.5 [15-25] mins for CMB, p = 0.004). Block performance properties did not differ between the groups. The only complication observed was vascular puncture with an incidence of 28% in Group CMB. CONCLUSIONS: Lateral approach costoclavicular technique provides fastest block onset than the other techniques. Considering the success and safety profile, this technique stands as a good alternative in clinical practice. TRIAL REGISTRATION: This study is prospectively registered to clinicaltrials.gov on 20/02/2022 (NCT05260736).
