In a randomized controlled trial, hemostatic effectiveness of a collagen-based composite (experimental group) was compared with standard hemostatic methods (ie, electrocautery and collagen sponge) (control group) at two bone sites. Hemostatic success, time to "controlled bleeding," and time to "complete hemostasis" were determined at the sternal edge following median sternotomy (n=64) and at the iliac crest following bone graft harvest (n=19). Almost twice the percentage of sternal edge patients (83% versus 44%, P=.002) and nearly three times the percentage of iliac crest patients (83% versus 29%, P<.05) achieved complete hemostasis in the experimental group compared to controls. Time to controlled bleeding and complete hemostasis for all bone sites also favored the experimental group over the control group at highly significant levels (P<.0001 for most comparisons). There were no adverse events related to experimental treatment use. The results support the use of this investigational hemostatic agent to control cancellous bone bleeding.
