The trial was registered prospectively at clinicaltrials.gov (NCT02715999).

Erector spinae plane block (ESPB) is a newly described interfascial plane block, and the number of articles on the bilateral application of ESPB is increasing in the literature. In this paper, in addition to analyzing bilateral ESPB cases and studies published so far, we aimed to review the relevant anatomy, describe the mechanism of spread of the injectant, demonstrate varying approaches to ESPB, and summarize case reports and clinical trials, as well as provide current insight on this emerging and popular block. Randomized controlled studies, comparative studies of ESPB versus other methods, and pharmacokinetic studies of bilateral applications must be the next step in clearly understanding bilateral ESPB.
