Impediment to local anesthetic solution in the epidural space results in unsatisfactory pain relief during labor epidural. Patients with a history of back trauma and spinal instrumentation have increased rates of epidural failure due to patchy spread of local anesthetic with obliterated epidural space. Dual Epidural Catheters (DEC) can be used in such clinical scenarios with complete labor analgesia and improved patient satisfaction. We present the successful management of a parturient with vertebral fracture at risk for epidural failure and neurologic injury due to bone fragments and inserted cranial and caudal to the fractured vertebra using ultrasound to avoid neurologic sequelae.
硬膜外腔中局部麻醉剂溶液的阻碍会导致分娩时硬膜外镇痛效果不理想。有背部创伤和脊柱器械置入史的患者由于局麻药分布不均匀和硬膜外间隙消失,硬膜外失败的发生率增加。双硬膜外导管 (DEC) 可用于此类临床情况,可实现完全分娩镇痛并提高患者满意度。我们介绍了一例使用超声引导避免神经后遗症的产妇病例,该产妇因骨折椎体上下的骨碎片和置入的颅骨和尾骨存在发生硬膜外失败和神经损伤的风险。
