However, reports on its PK in ECMO patients are limited. The aim is to develop a population pharmacokinetic (PK) model for hydromorphone in ECMO patients, so as to provide a reference for further research and clinical treatment. 26 ECMO patients (12 veno\u2010venous, 14 veno\u2010arterial) received hydromorphone infusion (0.03\u2009mg\u2009kg\n                    <jats:sup>\u22121<\/jats:sup>\n                    \u2009h\n                    <jats:sup>\u22121<\/jats:sup>\n                    ) for 72\u2009h. Blood samples were collected during and after infusion. Pharmacokinetics of hydromorphone was determined from arterial plasma concentrations. A nonlinear mixed\u2010effects modeling approach was used to analyze the hydromorphone concentration\u2010time data. A total of 484 plasma concentrations from 26 subjects were included in the population PK analysis. A three\u2010compartment model with first\u2010order linear elimination in the central compartment best described hydromorphone PK in veno\u2010venous and veno\u2010arterial ECMO patients. In veno\u2010venous ECMO, central compartment clearance was 0.955\u2009L\u2009min\n                    <jats:sup>\u22121<\/jats:sup>\n                    and volume of distribution was 23.6\u2009L; in veno\u2010arterial ECMO, these were lower at 0.657\u2009L\u2009min\n                    <jats:sup>\u22121<\/jats:sup>\n                    and 16.3\u2009L, respectively. Patients with elevated liver enzymes (alanine\/aspartate aminotransferase) exhibited substantially higher drug exposure, with geometric mean increases ranging from 9.59% to 19.8% observed across both ECMO modes. Veno\u2010arterial ECMO patients may require less hydromorphone than those on veno\u2010venous ECMO. Hepatic dysfunction was linked to increased drug exposure, suggesting the need for individualized dosing in ECMO patients.\n                  <\/jats:p>\n                  <jats:p>\n
