Anesthetic Techniques: Focus on Lumbar Erector Spinae Plane Block

Area of Science:

• Anesthesiology
• Pain Medicine
• Regional Anesthesia

Background:

• Erector spinae plane block (ESPB) is a frequently used interfacial plane block defined in the last decade.
• Lumbar ESPB, administered at lumbar levels, represents a novel approach in regional anesthesia and pain practice.

Purpose of the Study:

• To explain and introduce different approaches to lumbar ESPB.
• To elucidate the possible mechanisms of action of lumbar ESPB.
• To analyze existing case reports, clinical, and cadaveric studies on lumbar ESPB.

Main Methods:

• A comprehensive literature search was conducted in "Pubmed" and "Google Scholar" databases.
• Relevant studies were selected and analyzed, with 59 articles ultimately included in the review.

Main Results:

• The review analyzed various aspects of lumbar ESPB based on the selected literature.
• While considered reliable and easy, the current data suggests a need for further investigation.

Conclusions:

• Lumbar ESPB shows promise as a technique in regional anesthesia.
• Further anatomical and clinical studies are recommended to verify efficacy and indications.
• Pharmacokinetic studies are needed to confirm safety, and potential complications should be considered.
