Nerve stimulator-assisted sciatic nerve block for painful procedures in the ED

Area of Science:

• Emergency Medicine
• Anesthesiology
• Pain Management

Background:

• Emergency physicians often manage painful procedures requiring sedation.
• Parenteral sedatives and analgesics are common, but carry risks.
• Popliteal sciatic nerve block offers cardiopulmonary safety and prolonged analgesia.

Purpose of the Study:

• To evaluate the utility of sciatic nerve block in the popliteal fossa within the emergency department (ED).

Main Methods:

• Retrospective analysis of 16 ED popliteal nerve block cases (April 2009-April 2010).
• Indications included leg, ankle, and foot procedures (fracture reduction, splinting, etc.).
• Success defined by completion without additional sedation, patient satisfaction, and adequate analgesia.

Main Results:

• High patient satisfaction and successful procedure completion in all cases.
• Tibial nerve stimulation predicted block success.
• Excellent postprocedural analgesia lasting 90-120 minutes.

Conclusions:

• Popliteal nerve block is a viable alternative to parenteral procedural sedation for select lower extremity procedures in the ED.
• Further research is warranted due to the study's small size and retrospective design.
