The administration of narcotics into the spinal or epidural space has proven to be efficacious in the relief of mild to moderate pain. Unlike local anesthetics, intraspinal opioids are not associated with a decrease in systemic vascular resistance. Recent research has shown that opioids alone, or combined with local anesthetics, offer distinct advantages over the use of local anesthetics, alone when providing analgesia for the pregnant patient with cardiac disease.
已证明将麻醉药注入脊髓或硬膜外腔对缓解轻至中度疼痛有效。与局部麻醉药不同，脊髓内使用阿片类药物不会导致全身血管阻力降低。最近的研究表明，单独使用阿片类药物或与局部麻醉药联合使用，在为患有心脏病的孕妇提供镇痛时，比单独使用局部麻醉药具有明显优势。
