Lower Extremity Nerve Blocks

Abstract

Lower extremity nerve blocks are becoming more frequently used for anesthesia and postoperative analgesia in the setting of ambulatory surgery because of their favorable recovery and side-effect profiles. Perineural catheters can be placed in many situations to prolong duration of action, and patients are increasingly being sent home with catheters in situ and disposable infusion pumps. Ultrasound guidance is commonly used and may result in faster onset, increased success, and reduced performance time when compared with more traditional techniques. The purpose of this chapter is to discuss relevant details of these blocks, including theoretical and technical considerations, and to highlight developments from the recent literature that may influence your practice.
