Sciatic nerve block is a commonly used technique for providing anesthesia and analgesia to the lower extremity. At the parasacral level, the nerve block is classically performed via a posterior approach in lateral decubitus position causing patient's discomfort. Therefore, we aimed to conduct an anatomical study describing a new lateral approach to the parasacral sciatic nerve in supine position. ⋯ This study describes a new lateral approach to the parasacral sciatic nerve block in supine position. These anatomical results should be confirmed by further clinical studies.

The objective of our study was to clarify the topography of the medial and lateral pectoral nerves (LPNs) and the vascularity in the infraclavicular fossa and to propose an ideal injection point for neuromuscular blockade of the pectoralis major (PM) muscle. ⋯ We have identified an injection point which may be and suitable and safe location to administer neuromuscular motor blockade of the pectoralis muscles with a percutaneous local anesthetic agent in some clinical pathologies requiring elective denervation.
