Air injected into the epidural space may spread along the nerves of the paravertebral space. Depending on the location of the air, neurologic complications such as multiradicular syndrome, lumbar root compression, and even paraplegia may occur. However, cases of motor weakness caused by air bubbles after caudal epidural injection are rare. A 44-year-old female patient received a caudal epidural injection after an air-acceptance test. Four hours later, she complained of motor weakness in the right lower extremity and numbness of the S1 dermatome. Magnetic resonance imaging showed no anomalies other than an air bubble measuring 13 mm in length and 0.337 ml in volume positioned near the right S1 root. Her symptoms completely regressed within 48 hours.
注入硬膜外腔的空气可能会沿着椎旁神经扩散。根据空气的位置，可能会发生神经并发症，如多神经根综合征、腰椎神经根受压，甚至截瘫。然而，在硬膜外腔注射后因气泡引起的运动无力的情况很少见。一位 44 岁的女性患者在接受空气耐受试验后接受了骶管硬膜外注射。4 小时后，她主诉右下肢无力和 S1 皮节麻木。磁共振成像显示除了在右侧 S1 神经根附近有一个长 13 毫米、体积为 0.337 毫升的气泡外，没有其他异常。她的症状在 48 小时内完全消退。
