Intractable pain in 4 patients having disseminated cancer was treated by intraventricular morphine. For all these patients, previous efficiency of opiates therapy was assessed by a positive trial of epidural injections of morphine. The latter method had to be stopped and a switch to intraventricular morphine was motivated, in 3 cases, by a local non-tolérance to the subarachnoid catheter. ⋯ Trial times were respectively of 8 days, one month, two months and six months (this latter case still under trial). In comparison with the epidural and lumbar intrathecal administration of morphine, the authors insisted upon the quality of analgesia obtained, the absence of respiratory depression, the comfort and minimal daily quantities of morphine injected (inferior to one mg daily in three cases). Enlightened by these 4 cases, the authors also discussed the relative importance of the spinal and brain mechanisms involved in morphinic analgesia.

In pre-terminal and terminal gynaecological patients with persistent cancer pain, now it is possible to carry out some anthalgic methods associated or not to parenteral administration of non-narcotic or narcotic analgesic, i.e. intrathecal neurolytic injections and epidural narcotic administration. Many favourable results have been obtained by means of single or repeated 7% phenol in glycerine injections to patients with advanced but not terminal cancer affected by somatic and segmental pain or by perineal pain. ⋯ This method appears to be the best answer to many problems complained by the patients: pain, depression, malaise. As a matter of fact, low doses of epidural morphine induce both complete pain relief and sedation or slight drowsiness.
