High-definition ultrasound imaging defines the paraneural sheath and the fascial compartments surrounding the sciatic nerve at the popliteal fossa.
The connective tissue layers that surround the sciatic nerve at the popliteal fossa are poorly defined. We present high-definition ultrasound images of the sciatic nerve, which were acquired during ultrasound-guided popliteal sciatic nerve block (SNB), that clearly demonstrate these fascial layers. ⋯ We have demonstrated the paraneural sheath and the fascial compartments, that is, the "subepimyseal perineural compartment" and the "subparaneural compartment" that surround the sciatic nerve and act as conduits for local anesthetic spread during a popliteal SNB.

Promising effects of intravenous lipid emulsion as an antidote in acute tramadol poisoning.
In recent years, research has provided experimental and subjective evidence that intravenous lipid emulsions (ILEs) reverse some hemodynamically considerable poisonings with various drugs. The aim of this study was to investigate the possible antidotal effect of ILE on acute tramadol poisoning. ⋯ Intravenous lipid emulsion significantly reduced mortality due to acute toxicity with tramadol in rabbits, although increasing the ILE dose may cause reverse effects.
