Paraneuraxial nerve blocks: Can they replace neuraxial nerve blocks?

Abstract
Over the past 10-15 years, the quick development of ultrasound technique has rapidly changed the practice of regional anesthesia including the greater use of truncal nerve blocks. Some of the truncal blocks are performed just outside of neuraxial region, such as deep cervical plexus block (dCPB), paravertebral nerve block (PVB) and lumbar plexus block (LPB), in addition to Thoracolumbar Interfascial Plane (TLIP),1 retrolaminar block (RLB), erector spinae plane (ESP) block, and cervical columnar interfascial plane (CCIP) block, quadratus lumborum block III (QL, III), which are new techniques. These techniques are comparable to neuraxial nerve blocks in terms of analgesic efficacy and may confer many of advantages over neuraxial nerve blocks.2Specifically, neuraxial blocks are not site-specific, they cause hypotension, and some of them may lead urinary retention, the placement of Foley catheters, limited mobility.2-3 We have proposed the use of the new terminology “Paraneuraxial Nerve Block (ParaNXB)”.4 This new term provides a direct pictorial anatomy of the nerve block and would help clinicians develop clinical insights.5-7 The ParaNXB family may include the dCPB, PVB and the LPB, as well as ESP, RLB, TLIP block, CCIP block, QL III block and sympathetic chain block. We believe that ParaNXB will become even more popular clinically, due to its clinical and anatomical characteristics. It is thus clinically significant and beneficial in the practice, teaching, and training aspects of regional anesthesia. Study has shown that since 1990, wherein the relative percentage of spinal and epidural techniques has declined, and peripheral nerve blocks have increased.8 ParaNXBs will challenge the clinical role of the traditional neuraxial nerve blocks fundamentally.
