Bloqueo del plano del músculo erector espinal: estudio anatómico-cadavérico para determinar su mecanismo de acción

Human volunteer study examining the sensory changes of the thorax after an erector spinae plane block

“…Cadaver studies examining local anesthetic spread post an ESP block have shown inconsistent spread of dye. If cadaver studies were a football match, it would be 3–2 to paravertebral spread, with no explanation of how the ball ended up in the goal 4–8…”

<p>Efficacy of bilateral erector spinae plane block in the management of pain: current insights</p>

“…Vidal et al 13 reported that injectant spread was evident posterior to the transverse process deep to the erector spinae muscle, as well as the paravertebral and intercostal spaces. Spread to the neural foramina or epidural space was not evaluated.…”

“…While the needle length may change according to the location of the application and patient characteristics, generally a 22 G needle measuring 50, 80, or 100 mm is used for thoracic applications, while a 22 G needle measuring 80-100 mm should be used for lumbar or other applications. 4,7,13,28 Catheterization Catheter use in bilateral thoracic ESPB has been reported in the literature. Clinical trials using catheterization for bilateral ESPB in adults undergoing cardiac procedures have been reported.…”

Control analgésico continuo en paciente con múltiples fracturas costales mediante colocación de catéter en el plano profundo del músculo erector de la espina

“…analizaron específicamente el volumen y la concentración empleados en 49 casos de ESPB para analgesia por fracturas costales con el objetivo de encontrar unos protocolos óptimos, creando una guía basada en el peso. Sin embargo, no existe un claro consenso al respecto sobre la dosificación y la concentración exacta del AL (13). Probablemente, estas puedan variar según el objetivo analgésico que se pretenda conseguir.…”
