Anaphylaxis is an unanticipated severe allergic reaction that can occur during a surgical procedure. A patient is exposed to myriad foreign substances during surgery, such as anesthetic drugs, blood products, and surgical materials, including a commonly used hemostatic agent called Avitene Microfibrillar Collagen Hemostat. Anaphylaxis is the most severe immune-mediated reaction, and it generall...

CARDIAC surgery with cardiopulmonary bypass (CPB) poses serious hemostatic challenges in Jehovah’s Witnesses, who refuse blood transfusions on religious grounds. Excessive bleeding ( 2 l) after cardiac surgery is encountered in 5–7% of Jehovah’s Witness patients, and necessitates reexploration in 3.6% of cases. Recombinant factor VIIa (rFVIIa, NovoSeven®; Novo Nordisk, Princeton, NJ), produced ...

Microfibrillar collagen hemostat (MCH) is accepted as an effective topical hemostatic agent during endoscopic endonasal transsphenoidal surgery (EETS), particularly to achieve venous hemostasis; however, handling MCH may be troublesome because of its adherence to gloves and instruments. We describe here a method of "injection" of MCH suspension using a syringe applicator. This technique allows ...

control of hemorrhage is one of the challenging situations dentists confront during deep cavity preparation and before impressions or cementation of restorations. for the best bond and least contamination it is necessary to be familiar with the hemostatic agents available on the market and to be able to choose the appropriate one for specifi c situations. this review tries to introduce the comm...

results the hemostasis time for the ferric chloride concentration group was significantly less than for the control group (p < 0.001). materials and methods in this animal model study, 60 male wistar rats were used. an incision, 2 cm long and 0.5 cm deep was made on rat skin and the hemostasis time was recorded using ferric chloride at different concentrations (5%, 10%, 15%, 25%, and 50%) and t...

The purpose of this study was to evaluate the effect a hemostatic agent containing aluminum chloride on shear bond strength resin-modified glass ionomer cement (RMGIC) dentin primary teeth. Thirty-six extracted non-carious human teeth were collected in study. Dentin surfaces cut and polished. specimens randomly divided into 4 groups; group I: RMGIC without conditioning; II: polyacrylic acid (PA...
