| pubmed-article:18090443 | pubmed:abstractText | Intraspinal drug-delivery therapy has been increasingly used in patients with intractable nonmalignant pain syndromes during the past two decades. Morphine, the only FDA-approved opioid for intrathecal administration, has been the principle agent for such therapy. Although intrathecal morphine infusion can produce profound spinal analgesia, it may also cause some untoward side effects. We describe the first case of persistent hiccup caused by intrathecal morphine infusion therapy. | lld:pubmed |
