In Response:
We thank Dr. Boezaart (1) for his interest in our article (2) and valuable comments. We would like to take the opportunity to address the issues point by point.
First, the misinterpretation of the "Y" as the Boezaart needle insertion point is unfortunate and was not intended. The Boezaart needle insertion point is "at the V formed by the trapezius and levator scapulae muscles at the level of C6, between 4 and 12 cm lateral of the midpoint of the spinous process of C6" (3).
Second, in our study, only 2.5% of patients complained of cervical pain, which was easily treated with paracetamol or spontaneously resolved after catheter removal. In our experience with the posterior approach to the brachial plexus block, cervical pain ceased being an issue.
Third, the evidence of the inaccuracy of surface landmarks for the regional anesthesia technique is a major concern. Real-time imaging techniques are needed to improve the safety of regional anesthesia.
Last, we agree with Dr. Boezaart that the risk of pneumothorax should be very small with the posterior approach to the brachial plexus block.
