title: Topical hemostatic agents in otolaryngologic surgery.
abstract: Topical hemostatic agents are largely used to reduce blood loss during otolaryngologic surgery. These agents play an important role in both keeping the patient's hemodynamic equilibrium and allowing for a better view of the surgical field. These agents can be classified based on their mechanism of action, and include physical or mechanical agents. Most complications of topical hemostatic agents are sustained because of the antigenic reaction of those products. This paper reviews traditional and newer topical hemostatic agents with regard to their chemical properties, their mechanisms of action, and the benefits and complications of topical agents.
