[Morphine in the inferior cerebellar cisterna for oncologic pain in the ORL area].
The study aimed to assess whether the infusion of microdoses of morphine in the cisterna magna, close to the sensitive nuclei of the cranial nerves (V-VII-IX-X) involved in painful syndromes of the head and neck, is able to control severe oncological pain in this region which does not respond to traditional pain killing treatment or neurolesive practices. Cisternal catheters were inserted in eight patients with cancer of the head and neck. The intensity of pain was assessed using VAS and the quality of analgesia obtained using cisternal morphine was judged to be: excellent, good, inadequate or null. Treatment lasted a mean of 121 days. Good or excellent analgesia was achieved in 7 patients using a mean daily dose of 1.5 mg morphine during the initial stage and 4.8 mg during the final stage; in one patient with a large component of "deafferent pain", good pain relief was obtained by associating cisternal morphine with chlorimipramin per os. The side-effects observed were almost always short-term and easily resolved. Morphine treatment was begun in the hospital and in all cases continued at home. This efficacious pain killing method should be given adequate attention in the global strategies used to treat oncological pain in the head and neck region.
