新生児における腸骨筋面ブロック：症例報告

Pain in neonates, if not adequately treated, can lead to long-term neurological and behavioral 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.
