Sustained-release oral morphine versus transdermal fentanyl and oral methadone in cancer pain management.
The aim of this study was to compare the analgesic and adverse effects, doses, as well as cost of opioid drugs, supportive drug therapy and other analgesic drugs in patients treated with oral sustained-release morphine, transdermal fentanyl, and oral methadone.One hundred and eight cancer patients, no longer responsive to opioids for moderate pain, were selected to randomly receive initial daily doses of 60 mg of oral sustained-release morphine, 15 mg of oral methadone, or 0.6 mg (25 microg/h) of transdermal fentanyl. Oral morphine was used as breakthrough pain medication during opioid titration. Opioid doses, pain intensity, adverse effects, symptomatic drugs, were recorded at week interva…
Switching from Transdermal Drugs: An Observational "N of 1" Study of Fentanyl and Buprenorphine
The aim of this study was to confirm that the concomitant presence of transdermal fentanyl (TTS FE) and buprenorphine (TTS BU) may be feasible without important consequences, using doses presumed to be equianalgesic. A prospective "N of 1" study was carried out in a sample of volunteers with cancer pain receiving stable doses of TTS FE or TTS BU, with adequate pain and symptom control. In the study design, each patient provided data before and after a switch from one opioid to the other and then back to the previous one. Sixteen patients receiving daily stable doses of 0.6 or 1.2 mg of TTS FE were switched to TTS BU using an FE-BU ratio of 0.6-0.8. After three days, the TTS BU patch was rem…
Intravenous morphine for breakthrough (episodic-) pain in an acute palliative care unit: a confirmatory study.
The aim of this prospective cohort study was to confirm the safety of intravenous morphine (IV-M) used in doses proportional to the basal opioid regimen for the management of breakthrough pain and to record the nurse compliance on regularly recording data regarding breakthrough pain treated by IV-M. Over a one-year period, 99 patients received IV-M for breakthrough pain during 116 admissions. The IV-M dose was 1/5 of the oral daily dose, converted using an equianalgesic ratio of 1/3 (IV/oral). For each episode, nurses were instructed to routinely collect changes in pain intensity and emerging problems when pain became severe (T0), and to reassess the patient 15minutes after IV-M injection (…
Effects of red blood cell transfusion on anemia-related symptoms in patients with cancer.
The aim of this study was to assess the effects of red blood cell transfusion, and the subsequent increase in hemoglobin values, on anemia-related symptoms in a cohort of patients with cancer with different survival times. A red blood cell transfusion was recommended to a consecutive sample of patients with hemoglobin levels of 8 +/- 0.5 g/dL. The number of units to be ordered was decided according the hemoglobin values with a mean target of increasing the hemoglobin values by approximately 2 g/dL. Hemoglobin values, anemia-related signs and symptoms, including well-being, fatigue, and dyspnea, were recorded at admission (T0), 1 day after the last transfusion (T1), and 15 days afterward (T2…
