“…Since chronic LBP if often multidimensional and rarely exclusively myofascial, and agreeing with Galacho J. et al 5 when affirming that ESPB does not only block somatic fibers but also the sympathetic chain, we have been using the ultrasound-guided ESPB more often in our ambulatory patients with fairly good results. In a recent and not yet submitted to publication in BJAN case series (10 patients) of our Pain Clinic, we found a mean of 20.8 days of pain relief after L1-L2 bilateral injection of 20 mL ropivacaine 0.2% and dexamethasone (4 mg), with no need for systemic pharmacological therapy escalations or rescue analgesia.…”

“…Apesar do extenso uso nos últimos anos, o exato mecanismo de ação do BPE não está completamente elucidado, tendo em vista que os estudos que analisam dispersão de BPE apresentam resultados bastante variáveis, tanto em humanos vivos quanto em cadáveres. (31,32,(53)(54)(55)(56)(57)(58)(59) A dispersão para ramo dorsal ocorre para diversos níveis espinhais adjacentes, mas a maioria dos estudos demonstra que a dispersão anteroposterior de anestésico local depositado no BPE para o espaço paravertebral não ocorre de forma consistente para bloqueio do ramo ventral, apesar de factível. (32,53,54,57,59,60) A dispersão do AL restrita ao ramo dorsal também é corroborada pelos trabalhos de Zhang et al e…”
