Study Objective |
To determine if there is a difference between the vertical and coracoid approaches to the infraclavicular block.
Design |
Randomized, double-blinded clinical trial.
Setting |
University-affiliated medical center.
Patients |
60 ASA physical status 1 and 2 patients undergoing surgery of the forearm and hand.
Interventions |
Patients were randomized to two groups: Group VIP (vertical infraclavicular approach; n=30) and Group Coracoid (coracoid infraclavicular approach; n=30). In the infraclavicular coracoid approach, the coracoid process was used as the landmark. Needle positioning was guided by nerve stimulation.
Measurement |
For each approach, the quality of sensory and motor block was assessed and recorded separately for each of the 4 major nerves of the upper limb.
Main Results |
The infraclavicular coracoid approach (11±1 min) was faster to perform than the vertical infraclavicular block (14±1 min; P < 0.05). The infraclavicular coracoid approach yielded a shorter sensory block onset time (2.3±1.3 vs 3±1.3 min; P < 0.05). In the coracoid group, a pronounced sensory and motor block was noted in the area innervated by the musculocutaneous nerve (P < 0.05).
Conclusion |
The coracoid approach is convenient to perform with extensive block, and is thus an appropriate alternative to the vertical approach in infraclavicular block.
