Successful Pain Control in Cancer Patient on Palliative Therapy by Partial Opioid Rotation

Our palliative care team intervened in a patient with sciatica resulting from metastasis to sacral bone after surgery for rectal cancer. Rapid pain control and a change in the route of rescue drug administration from the stoma were needed. Partial opioid rotation was performed. The dose of 25.2 mg in 72 hours in a transdermal fentanyl patch decreased to 16.8 mg in 72 hours, and the dose of 3.6mg in an hour by continuous intravenous injection of morphine was added. The change in the rescue root to intravenous administration by a patient-controlled analgesia pump gave the patient relief from his pain. He was able to attend his daughter’s wed-ding. His family were all pleased with the relief provided. The advantages of this partial opioid rotation are summed up in the following three points : (1) The required time is relatively short ; (2) It can be expedient for analgesia due to the addition of different opioids ; and (3) The partial opioid rotation produces fewer adverse effects than a full opioid rotation. Adjustment of the amount of drugs for pain relief in cancer patients is important with the situations of the patient and the family taken into consideration fully.
