ABSTRACT
Background: Hydromorphone is an analogue of morphine used in the treatment of cancer-related pain. There have been few studies that have evaluated the analgesic effect upon transition from hydromorphone injections. The aim of this study was to evaluate the conversion ratio between injection and oral preparation. Methods: We conducted a retrospective chart study of consecutive patients who were admitted to our hospital between July 2018 and December 2019. Results: In six patients, when the conversion ratio from hydromorphone injection to oral was changed at a 1:5 conversion ratio, three patients obtained adequate analgesic effects, the analgesic effect was insufficient in one case and an increased dose was required. Significant drowsiness appeared in two patients who required a decrease in dose. Conclusions: In converting from hydromorphone injections to oral preparations, it is necessary to carefully monitor the analgesic effect and adverse events and adjust the dosage for each case regardless of the conversion ratio.
ABSTRACT
<b>Case</b>: A 71-year-old woman with diabetes mellitus was diagnosed as end-stage ovarian cancer. She was suffering from stomachache and anorexia because of massive ascites. Although we performed abdominal paracentesis for symptomatic palliation, ascites accumulated again in a few days. In order to control the refractory ascites, we administered intraperitoneal triamcinolone acetonide (10 mg/kg) after the fourth abdominal paracentesis; consequently, the interval between the consecutive abdominal paracentesis procedures was extended remarkably. However, prolonged hyperglycemia occurred despite the administration of a single dose of triamcinolone acetonide, and insulin therapy was required for eight days. <b>Conclusion</b>: To our knowledge, this is the first report of intraperitoneal administration of triamcinolone acetonide that caused prolonged hyperglycemia. Therefore, this drug should be administered with caution in such patients with diabetes mellitus.
