Geneic Dose Calculation Anti-hemophilic factor derived from human and recombinant plasma Monoclate-P Koate-DVI Hemofil M Helixate FS Kogenate FS Recombinate Advate Refacto Xyntha The dose of the factor VIII concentrate is mainly based on the severity and location of the bleeding and the necessary levels of the circulation factor. In the absence of inhibitors, each factor VIII unit will increase endogenous factor levels by 2 IU / dL. The initial dose of the factor can be determined by: Desired dose (UI) = body weight (kg) x levels of factor x 0.5 intravenously. The administration rate should not exceed 3 ml / minute for adults and 100 IU / minute in young children. Circulating levels of factor VIII should be measured 15 minutes after the infusion. Subsequent doses are based on the recovery and half-life of factor VIII for each individual patient. Factor IX, derived from human plasma The recovery of factor IX is lower with recombinant factor IX compared to plasma-derived products, which require a higher dose. The initial dose can be calculated as: Adults Desired dose (IU) = Body weight (kg) x Factor level intravenously. 0.7 The administration rate should not exceed 3 ml / minute for adults and 100 IU / minute in young children. Factor IX, recombinant Rixubis One international unit of RIXUBIS per kg of bodyweight increased the circulating activity of factor IX by 0.9 international units / dL. Initial Dose: Required international units = body weight (kg) x desired factor IX increase (% of normal or IU / dL) x reciprocal of observed recovery (IU / kg per IU / dL). Maintenance dose depends: ▪ Type of bleed or surgery, the intensity of the hemostatic challenge, and number of days until adequate wound healing is achieved. Routine prophylaxis: 40 to 60 international units per kg twice weekly. Plasma-derived Factor IX complex Bebulin VH Profilnine SD Bebulin: In the absence of inhibitors, each factor IX unit will increase endogenous factor levels of 0.8 IU / dl. The initial dose of concentrate of the factor necessary to achieve the desired level can be determined by: Desired dose (UI) = Body weight (kg) x Levels of factor x 1.2 intravenously. Profilnine SD: In the absence of inhibitors, each factor IX unit will increase endogenous factor levels by 1 IU / dL. The initial dose of factor concentrates needed to achieve the desired level can be determined by: Desired dose (UI) = Body weight (kg) x Factor level intravenously. The administration rate should not exceed 2 ml / minute. Circulating levels of factor IX should be measured 15 minutes after infusion. Subsequent doses are based on the recovery and half-life of factor IX for each individual patient. Anti-coagulant inhibitor complex, plasma derivatives FEIBA NF FEIBA VH 50 to 100 IU / kg administered intravenously every 6 to 12 hours, depending on the severity and location of the hemorrhage. The administration rate should not exceed 2 IU / kg / minute. Factor VIIa, recombinant NovoSeven RT Hemophilia A or B with inhibitors: 90 mcg / kg every 2 hours as an intravenous bolus until hemostasis is achieved. Doses of 35 to 120 mcg / kg have been used in clinical trials. Congenital Factor VII Deficiency: 15 to 30 mcg / kg every 4 to 6 hours. Doses as low as 10 mcg / kg have been effective. Acquired hemophilia: 70 to 90 mcg / kg every 2 to 3 hours until hemostasis is achieved Complex antihemophilic factor derived from human plasma / von Willebrand factor Humate-P Alphanate Hemophilia A: The dose of factor VIII concentrate is mainly based on the severity and location of the bleeding and the necessary levels of circulation factor. In the absence of inhibitors, each factor VIII unit will increase the endogenous factor levels of 2 IU / dL. The initial dose of concentrate of the factor necessary to achieve the desired level can be determined by: Desired dose (UI) = Body weight (kg) x levels of factor x 0.5 intravenously. The administration rate should not exceed 3 ml / minute for adults and 100 IU / minute in young children. Circulating levels of factor VIII should be measured 15 minutes after the infusion. Subsequent doses are based on the recovery and half-life of factor VIII for each individual patient. Von Willebrand disease: Each unit of endogenous factor VIII will increase the von Willebrand factor by 5 IU / dl Treatment of bleeding episodes: 40 to 80 IU / kg every 8 to 12 hours intravenously. Subsequent doses are adjusted based on the severity and location of the hemorrhage. Perioperative management: One loading dose (eg, 50 to 60 IU / kg) followed by maintenance dose of approximately half the intravenous loading dose. Both the loading dose and the maintenance dose should be adjusted based on the type of surgery. The administration rate should not exceed 4 ml / minute of Humate-P and 10 ml / minute for Alphanate Factor VII complex derived from human plasma with von Willebrand factor Wilate A loading dose of 20 to 60 IU / kg, depending on the severity of the bleeding, followed by a maintenance dose of 20 to 40 IU / kg every 12 to 24 hours intravenously. 3. Prophylactic Therapy. a. Therapy. prophylactic with anti-hemophiliac factors may be considered in the following situations: ▪ Patient with severe hemophilia A or B defined by a level of coagulation factor <1%. ▪ Patients with repeated episodes of bleeding, mainly in the joints. Secondary prophylaxis can be considered for 4-8 weeks. ▪ Previous prophylactic therapy and after surgery or invasive procedure for up to 14 days. 4. Anti-hemophilic factors will be available for the management of the following cases a. Suspected bleeding in joints or muscles b. Any injury to the head, neck, mouth or eyes or evidence of bleeding in some of these areas. c. Unusual headache, particularly if it is followed by trauma d.
