Efficacy and safety of a novel hemostatic material, BoneStat, compared with Ostene and Bone Wax in a rat calvarial defect model.

Abstract

Hemostasis has critical significance during surgical procedures. Bone Wax has traditionally been commonly used for bone hemostasis despite well-documented undesirable side effects: hindering osteogenesis and induction of inflammatory reactions with consequent increase in infection rates. A later developed formulation, Ostene, offers an alternative to Bone Wax with lesser undesired effects. In this study, BoneStat, a newly developed bone hemostatic formulation comprising water-soluble alkylene oxide co-polymers, was evaluated for water solubility, hemostatic efficacy, ease of handling, bone healing efficacy, and inflammatory reactions compared with Bone Wax and Ostene in a rat calvarial defect model. More than 95% of BoneStat was dissolved in water within 48 h, as was Ostene, but not Bone Wax. The time to hemostasis using BoneStat was significantly faster than with Ostene or Bone Wax. BoneStat also improved ease of handling compared to Ostene or BoneWax. BoneStat- and Ostene-treated groups constantly showed better bone healing than with Bone Wax. The BoneStat and Ostene groups presented no evidence of chronic inflammation reaction contrary to Bone Wax. These results suggest improved hemostasis, ease of handling, non-hindering bone healing, and unnoticeable chronic inflammatory reactions with BoneStat. Thus, Bonestat is a useful and reliable formulation for mechanical hemostasis.
