Although they have been documented, opioid treatments in obstetrics are mostly limited to methadone maintenance treatment in pregnant addicts or analgesia/anesthesia for labor. A literature search revealed no previous studies describing analgesic techniques for relief of severe cancer pain in pregnant patients. As response to morphine is dose- dependent, its conventional use can be problematic in pregnant women suffering from severe cancer pain because it is important to prevent opioid intoxication of the fetus. Furthermore, long-term exposure to morphine may result in physical dependence on the drug by the fetus, causing acute withdrawal syndrome and growth retardation after delivery. We report our experience in treating a 35-year-old pregnant female, in her 32nd gestational week, suffering from neuropathic pain due to advanced ovarian cancer. Using a microcatheter technique, we administered small doses of morphine intrathecally and successfully controlled the pain before delivery without complications in the mother and fetus. Treatment options of systemic vs spinal and epidural vs intrathecal opioids under such unique circumstances are discussed.
