Coagulation and Laser Coagulation Print E-mail

Dr. Kennedy Coagulation refers to the clotting of blood, the process by which the blood congeals to form solid masses, or clots. More than 30 types of cells and substances in blood affect clotting. The process is initiated by blood platelets. Platelets produce a substance that combines with calcium ions in the blood to form thromboplastin, which in turn converts the protein prothrombin into thrombin in a complex series of reactions. Thrombin, a proteolytic enzyme, converts fibrinogen, a protein substance, into fibrin, an insoluble protein that forms an intricate network of minute threadlike structures called fibrils and causes the blood plasma to gel. The blood cells and plasma are enmeshed in the network of fibrils to form the clot.

Laser coagulation is the coagulation (clotting) of blood using a laser. A coagulation laser produces light in the visible green wavelength that is selectively absorbed by hemoglobin, the pigment in red blood cells, in order to seal off bleeding blood vessels. There are other ways of provoking coagulation, namely electrocoagulation and photocoagulation.
