We studied 29 patients in the final stage of head or neck cancer who were s
uffering pain that was not relieved by oral morphine. Cervical or thoracic
epidural morphine was administered to relieve the pain. The quality of anal
gesia was equally good for both techniques. However, cervical epidural admi
nistration appeared to be superior, because much smaller doses of morphine
were required in order to induce more rapid and longer analgesia.
