Activated Prothrombin Concentrates in Management of Bleeding in a Classical Hemophiliac with Inhibitor
Bleeding in hemophiliacs with circulating anticoagulants is still a serious management problem. We would like to report our efforts at achieving hemostasis in a 31 year old AHF deficient severe hemophiliac with inhibitor detected in Feb. 1972. He presented with right forearm flexor compartment bleed which did not respond to conservative management with Konyne (30 u/kg q3h) and necessitated a fasciotomy to relieve compression. No hemostasis occurred until 4 hrs. post-operatively when he received his first infusion of Auto-Factor IX*, 6 vials (60 u/kg). At this time he also received blood for his shocky state. With the institution of regular infusions of Auto-Factor IX alternating with Konyne, hemorrhage was controlled. A week later a split thickness skin graft (from R. thigh) was applied. With continued infusions of mainly Auto-Factor IX (60 u/kg q6h) the grafted and donor sites healed. The patient was subsequently discharged with full range of movement in all limbs. His inhibitor levels which ranged between 1 - 3 Bethesda units/ml shortly after admission over a period of 3 weeks rose to over 100 units/ml. Six months after the episode his inhibitor levels are still over 100 units/ml. Activated prothrombin concentrates are effective in hemostatic control of life-threatening bleeding in hemophiliac patients with inhibitors.* Kindly supplied by Dr. Aaron Josephson, Travenol Laboratories, Chicago, 111.
