Erector Spinae Plane Block and Chronic Pain: An Updated Review and Possible Future Directions

SIMPLE SUMMARY: Erector spinae plane block is a technique used by anesthesiologists and pain physicians. It was introduced in 2016 and consists of an injection of local anesthetic between a vertebra and its corresponding muscle (erector spinae). It provides diffuse somatic and visceral analgesia useful for both surgery and pain therapy. In our paper we overview chronic pain, fascial blocks and erector spinae plane blocks. We give an overview of the erector spinae plane block technique, complications and possible use in chronic pain settings, highlighting the current evidence with a final overview of possible future directions of research. ABSTRACT: Chronic pain is a common, pervasive, and often disabling medical condition that affects millions of people worldwide. According to the Global Burden of Disease survey, painful chronic conditions are causing the largest numbers of years lived with disability worldwide. In America, more than one in five adults experiences chronic pain. Erector spinae plane block is a novel regional anesthesia technique used to provide analgesia with multiple possible uses and a relatively low learning curve and complication rate. Here, we review the erector spinae plane block rationale, mechanism of action and possible complications, and discuss its potential use for chronic pain with possible future directions for research
