Continuous parasacral sciatic block: a radiographic study.

Unlabelled: Parasacral sciatic blockade results in anesthesia of the entire sacral plexus. In this study we sought to determine the spread of the local anesthetic injected through a parasacral catheter, the anatomical location of the inserted catheters, and the extent and reliability of the blockade. In this study, 87 consecutive patients undergoing major lower limb surgery were enrolled.

Continuous lumbar plexus block: Use of radiography to determine catheter tip location.

Background And Objectives: The purpose of this article is to document where a lumbar plexus catheter introduced by the posterior approach will track and to evaluate the benefit of using systematic radiographic verification of catheter placement.

Methods: A continuous lumbar plexus block (CLPB) by the posterior approach was performed on 169 consecutive adult patients scheduled for major hip, thigh, or knee surgery. Each catheter was verified by radiography using 10 mL contrast medium.
