Novel ultrasound-guided inter-semispinal plane block: a comparative pilot study in healthy volunteers

Abstract

We previously reported that a novel multifidus cervicis plane (MCP) block could anesthetize the dorsal rami of the cervical spinal nerves. While MCP sonoanatomy is easily detectable in most patients, it is sometimes difficult to recognize the MCP injection plane, especially in elderly patients. Thus, we proposed the inter-semispinal plane (ISP) block as an alternative for the MCP block. The aim of this study was to evaluate the utility of the ISP block by evaluating the area and duration of anesthesia, compared with that of the MCP block in eight healthy volunteers. Each participant underwent unilateral ultrasound-guided MCP block and ISP block. For each block, 20 ml of ropivacaine 0.2% was injected, and the area of anesthesia was determined using the pinprick test. The anesthetic area ranged from C4 to T2 (3/8; 37.5%), T3 (2/8; 25%), or T4 (3/8; 37.5%) in the MCP block, and from C4 to T1 (1/8; 12.5%), T2 (3/8; 37.5%), T3 (2/8; 25%), or T4 (1/8; 12.5%) in the ISP block. The mean (standard deviation) duration of sensory loss following MCP and ISP blocks was 329 (77) min and 349 (70) min, respectively. Thus, the ISP block may be a reliable alternative to the MCP block.
