ABSTRACT
This study examined the effects of intrathecal analgesia (ITA) using an extracorporeal pump with a subcutaneous port system in cancer patients with bone metastasis. Among the patients who died of cancer with bone metastasis at the palliative care unit of our institution, 11 who received ITA were selected. Changes in pain, opioid doses, the palliative prognostic index (PPI), and Eastern Cooperative Oncology Group Performance Scaleãafter ITA were assessed. Pain, opioid doses, and PPI decreased after ITA (P = 0.002, 0.002, and 0.017). ITA for cancer patients with increased PPI due to refractory cancer bone pain decreased pain, opioid doses, and PPI.(100 words).

A 25-year-old parturient with Marfan's syndrome was scheduled for cesarean delivery. She suffered with severe scoliosis and asymptomatic aortic root dilatation. To establish a cardiovascular stability and prevent aortic dissection perioperatively, we selected the use of remifentanil, an ultra-short acting opioid analgesic with general anesthesia. General anesthesia was induced with remifentanil (0.2 microg x kg(-1) x min(-1)), propofol (100 mg), and vecuronium bromide (10 mg). Anesthesia was maintained with 100% O2, sevoflurane (1-1.5%), and remifentanil (0.2-0.25 microg x kg(-1) x min(-1)). She remained hemodynamically stable during surgery. A lively infant was delivered and Apgar scores were 8 and 9 at 1 and 5 min, respectively. Their post-delivery courses were uneventful. Remifentanil was useful for anesthetic management in a pregnant patient with Marfan's syndrome undergoing cesarean delivery, although attention to infant's respiratory condition should be paid because remifentanil can cross the placenta.
