Sztain JF, et al. - Whether the catheter insertion point “deep” to the paraneural sheath immediately distal to the bifurcation between the tibial and common peroneal branches can improve postoperative analgesia during a continuous popliteal-sciatic nerve block when compared with the traditional approach “superficial” to the paraneural sheath proximal to the bifurcation, was investigated in this study. For 31 subjects in whom the catheter was inserted at the proximal subparaneural location vs for 32 subjects in whom catheter was inserted at the distal supraparaneural location, the estimated average pain (0–10 scale) the morning following surgery was a median (interquartile) of 1.5 (0.0–3.5) vs 1.5 (0.0–4.0), respectively. The observed secondary outcomes were similarly negative.
