BACKGROUND Plasma-derived bovine thrombin is used as a topical agent to improve surgical hemostasis, but development of antibodies to bovine hemostatic proteins has been associated with increased bleeding and thrombotic complications. Recombinant human thrombin could reduce the risk of these complications. STUDY DESIGN The objective of this randomized,(More)
BACKGROUND This Phase 3, international, randomized, single-blind, controlled trial (FINISH-3) compared the efficacy and safety of Fibrocaps, a ready-to-use, dry-powder fibrin sealant containing human plasma-derived thrombin and fibrinogen, vs gelatin sponge alone for use as a hemostat for surgical bleeding in 4 indications (ie, spinal, hepatic, vascular,(More)
BACKGROUND CONTEXT Multilevel fusions, the use of allograft bone, and smoking have been associated with an increased risk of nonunion after anterior cervical discectomy and fusion (ACDF) procedures. Pulsed electromagnetic field (PEMF) stimulation has been shown to increase arthrodesis rates after lumbar spine fusion surgery, but there are minimal data(More)
BACKGROUND The immunogenicity and safety of recombinant human thrombin (rThrombin) were evaluated in this phase 3b, open-label, single-group, multisite study of 209 adult vascular and spinal operation patients at high risk for preexisting anti-bovine thrombin product antibodies. STUDY DESIGN Patients received rThrombin applied as a topical hemostat during(More)
Topical hemostats, fibrin sealants, and surgical adhesives are regularly used in a variety of surgical procedures involving multiple disciplines. Generally, these adjuncts to surgical hemostasis are valuable means for improving wound visualization, reducing blood loss or adding tissue adherence; however, some of these agents are responsible for(More)
BACKGROUND Immunoassays that detect antibovine thrombin product antibodies are not widely available. However, knowing whether these antibodies are present preoperatively would be useful because re-exposure to bovine thrombin-containing products is contraindicated in patients with pre-existing antiproduct antibodies due to the risk of developing(More)
