[Role of continuous intravenous infusion of morphine in the cancer pain relieving therapy].

Oral morphine treatment for cancer pain relief is established as central parts of 'WHO Regimen'. But many terminal stage cancer patients suffer from swallowing difficulty and nausea, and require other administration routes of morphine. Continuous intravenous infusion(CIVI) of morphine is the most reliable route at these conditions. We have had good results from the treatment of over 600 cancer pain patients with CIVI-morphine method. We interpreted our practical methods of CIVI-morphine treatment and commented on recently introduced injection 'morphine--100 mg/10 ml prefilled syringe', Prepenon injection.
