Abstract

Pain in neonates, if not adequately treated, can lead to long-term neurological and behavioural consequences. Among the most frequent causes are intrapartum fractures. Although rare, rib fractures represent a diagnostic and therapeutic challenge. This article presents the case of a 36-week neonate with a left rib fracture who exhibited symptoms such as inconsolable crying, feeding refusal, and oxygen desaturation. An ultrasound-guided erector spinae plane block (ESPB) was performed, resulting in significant clinical improvement without complications. Although ESPB has been widely used in adults and older children for the management of thoracic pain, its application in neonates is scarcely documented. This technique offers advantages over other regional analgesic methods, as it is associated with fewer adverse effects and provides direct analgesia to the thoracic nerves. Its use is suggested as a safe and effective alternative, particularly in non-surgical settings.

Resumen

El dolor en neonatos si no se trata adecuadamente puede tener consecuencias neurológicas y conductuales a largo plazo. Entre las causas más frecuentes se encuentran las fracturas intraparto. Aunque raras, las fracturas costales suponen un desafío diagnóstico y terapéutico. Este artículo presenta el caso de un neonato de 36 semanas con fractura costal izquierda, que mostró síntomas como llanto inconsolable, rechazo al alimento y desaturación. Se utilizó el bloqueo del plano del erector de la espina (ESPB), guiado por ecografía, obteniendo una mejoría significativa sin complicaciones. Aunque el ESPB se ha usado en adultos y niños mayores para dolor torácico, su aplicación en neonatos es poco documentada. Esta técnica presenta ventajas sobre otros métodos analgésicos regionales, al tener menos efectos adversos y actuar directamente sobre los nervios torácicos. Se sugiere su uso como alternativa segura y eficaz, especialmente en contextos no quirúrgicos.
