The first spray-dried fibrin sealant used to control bleeding during surgery has gained FDA approval.
Raplixa is a biological product that contains fibrinogen and thrombin, 2 proteins found in human plasma. The sealant dissolves in blood, triggering a reaction between those proteins, which forms blood clots to stop small blood vessels from bleeding when standard techniques such as suture, ligature, or cautery are ineffective or impractical (http://1.usa.gov/1HVGQSd).
