Catheter-over-needle method facilitates effective continuous infraclavicular block

摘要

We read with great interest the excellent article written by Dr. Lecours et al which reported an observational cohort study of all ultrasound-guided single-injection infraclavicular blocks (ICBs) performed over a two-year period at their institution. The authors observed that ultrasound-guided ICB performed with a single injection posterior to the axillary artery is a reasonably safe technique associated with a high success rate regardless of the expertise of the anesthesiologist performing the block. Experience within our institution is consistent with this observation, and we would agree strongly that ICB performed by single injection posterior to the axillary artery is safe and effective. Further, this provides an excellent approach for placement of a continuous catheter using a catheter-over-needle technique.
