Interfascial plane blocks.

Many novel interfascial plane blocks have been developed in the last 10 years in the effort to improve perioperative pain management that are safe, efficacious, efficient, and inexpensive. These blocks have been widely adopted into clinical practice despite relatively few high-quality clinical investigations of the techniques and how they affect perioperative outcomes. This article defines interfascial plane blocks, discusses the potential benefits, reviews the most common techniques and evidence supporting their indication, and guides clinicians in selecting an appropriate interfascial plane block for different types of surgical procedures.
