title: Patient-controlled subcutaneous hydromorphone versus continuous subcutaneous infusion for the treatment of cancer pain.
abstract: Twenty-five patients with pain due to advanced cancer were randomized to receive patient-controlled sc injections (PCIs) of hydromorphone (HM) versus continuous sc infusion (CSCI) of HM by means of a Pharmacia 5200 pump. Each self-injection of HM during PCI was equivalent to 4 hours of CSCI. After 3 days, a crossover occurred, and patients received the alternate treatment for 3 days. During both phases of the study, patients could request extra doses of HM from their nurses. In 22 patients able to be evaluated, pain intensity (visual analogue, 0-100 mm) at 9:00 a.m. and 4:00 p.m. was 31 +/- 23 and 28 +/- 18 mm, respectively, on PCI versus 28 +/- 18 and 27 +/- 17 mm, respectively, on CSCI [P = not significant (NS)]. The total dose of HM was 168 +/- 197 and 181 +/- 234 mg on PCI and CSCI, respectively (P = NS). No significant difference was found in nausea, drowsiness, or number of hours of sleep. The total number of extra doses of HM was 6 +/- 7 on CSCI versus 2 +/- 3 on PCI (P = .007). At the end of the study, patients chose PCI and CSCI in seven and 10 cases, respectively (P = NS; 5 patients expressed no preference). We conclude that both methods were similar in regard to effectiveness and toxic effects in short-term hospital use.
