An epidural performed for obstetric analgesia was initially characteristic of a subdural block but subsequently behaved as a normal epidural. Radiological confirmation of the catheter having been subdural was established by performing a magnetic resonance imaging scan.
一例用于产科镇痛的硬膜外阻滞最初表现出硬膜下阻滞的特征,但随后表现为正常的硬膜外阻滞。通过进行磁共振成像扫描确定导管位于硬膜下的影像学证据。
