The Effects of ECMO on the Pharmacokinetics of Hydromorphone

Hydromorphone was administered intravenously at a rate of 0.03 mg/kg/h for 72 h for analgesia. Blood samples were collected before administration and at different time points after administration, and the contents of hydromorphone and hydromorphone-3-glucuronide (main metabolite) were detected by quantitative liquid chromatography tandem mass spectrometry, and then A population pharmacokinetic model of hydromorphone in patients under ECMO was established.
