Epidural morphine for outpatients with severe anginal pain.

Seven patients who had chronic coronary artery disease and had undergone coronary artery bypass surgery still suffered from anginal attacks several times daily despite optimal medical treatment. An epidural system of analgesia was implanted subcutaneously and treatment with epidural morphine started. The morphine was administered by the patients themselves or members of their family. During a median observation time of four months (range three to 11) all patients were free of pain while receiving this treatment.
