We read with interest the first human randomized, controlled trial of the “Suture-method versus Through-the-needle Catheters for Continuous Popliteal-sciatic Nerve Blocks” by Finneran et al.1  The technique was developed and first demonstrated in cadavers by Rothe et al. for popliteal sciatic block in prone position.2,3  The method relies on the curvature of the needle and enough space available for it to reliably exit and not in close proximity to the surgical field or other vital structures.
Unfortunately, a successful new catheter system needs to have a design that fits all the nerve block locations and all patient sizes, and this one suffers from numerous drawbacks (pertaining to infection risk, challenging nerve locations, etc.), which the authors have already pointed out in great detail.1–3
