Two Cases of Suspected Subdural Migration of Labor Epidural Catheter with Horner’s Syndrome

Abstract

Epidural catheter migration into the subdural space is a potential complication with epidural analgesia. Subdural analgesia can result in high spinal anesthesia leading to cardiac arrest, and requires prompt diagnosis and adequate measures. Therefore, it is necessary to identify and respond to subdural migration without delay. We experienced two cases of suspected subdural migration during labor analgesia with Horner’s syndrome. The catheter was withdrawn by 1 cm in the first case, and was replaced in the second case, resulting in the relief of Horner’s syndrome while maintaining effective analgesia in both cases.
