Grey indicates obligatory measurements.
FVIII measurements are shown here until day 3 after start of combination treatment. Monitoring will continue if treatment is still necessary.
*Only in case of elective surgery, otherwise before first desmopressin administration.
†Pre, before desmopressin; post, after desmopressin; peak, after FVIII concentrate; post-treat=after surgery; in case of bleeding: 2–6 hours after desmopressin, trough, before next dose of FVIII concentrate.
‡Pre, before desmopressin; post, after desmopressin; peak, after loading dose FVIII concentrate; post-treat, after surgery; in case of bleeding: 2–6 hours after desmopressin; preadjust, before dosage; steady state, FVIII measurement at random time point.
