Clinical TrialSpread of local anesthetics after erector spinae plane block: an MRI study in healthy volunteers.
Erector spinae plane block (ESPB) is a truncal fascial block with a disputed mechanism and anatomical site of effect. This study aimed to perform a one-sided ESPB and use MRI to investigate the spread of the local anesthetic (LA) and the corresponding cutaneous loss of sensation to pinprick and cold. ⋯ We found that LA consistently spreads to the intercostal space, the paravertebral space, and the neural foramina after an ESPB. Epidural spread was evident in four volunteers. Sensory testing 30-50 min after an ESPB shows highly variable results, and generally under-represents what could be expected from the visualized spread on MRI 60 min after block performance.

American Society of Regional Anesthesia and Pain Medicine 2021 John J. Bonica Award Lecture.
I am as deeply inspired and humbled to receive this prestigious award, as I am profoundly indebted to the Bonica Award selection committee and the American Society of Regional Anesthesia and Pain Medicine Board of Directors for recognizing my contributions to the development, teaching, and practice of pain medicine in the tradition of Dr John J Bonica. I would also like to recognize my parents, Aura and Tito for providing me with the support and the environment to fulfill my professional goals. Moreover, the support that I have gotten from my team at the hospital, and the Chair of my Department, Dr Mark Lema needs to be underscored.
