Summary
Plexus nerve blocks for the lower limb, utilizing nerve stimulators, offer reliable postoperative analgesia for proximal limb surgeries. Commonly used doses of local anesthetics remain within safe plasma concentration limits.
Area of Science:
- Anesthesiology
- Pain Management
- Regional Anesthesia
Context:
- Plexus nerve blocks for the lower limb, while historically described, have seen recent resurgence in clinical use.
- Postoperative analgesia is a primary indication for these nerve blocks.
- Proximal lower limb surgeries often necessitate blockade of both the lumbar and sciatic plexuses.
Purpose:
- To review the techniques, indications, and safety of lower limb plexus nerve blocks.
- To highlight the role of nerve stimulators in improving block performance and reliability.
- To discuss the pharmacokinetic profile of local anesthetics used in these blocks.
Summary:
- Lower limb plexus nerve blocks, particularly those involving the lumbar and sciatic plexuses, are increasingly utilized for postoperative pain relief.
- Nerve stimulator-guided techniques enhance the ease and reliability of performing these blocks.
- Pharmacokinetic data indicate that commonly administered doses of local anesthetics do not reach toxic plasma concentrations.
Impact:
- Provides a comprehensive overview of lower limb plexus nerve blocks for surgical procedures.
- Emphasizes the safety and efficacy of these blocks, supported by pharmacokinetic data.
- Supports the expanded use of these blocks in day case surgery and for high-risk patients.
