Hemostasis in cardiac surgery is still a severe problem for surgeons. Blood and its products are the most valuable at the same time dangerous arms of surgeons. Industries produced many biological or non-biological products, which increase the cost of operations, are available for this issue. Decision making and producing solutions must be the most important properties of a cardiac surgeon. In any condition and resources, true strategy and patience will bring the success. Antiaggregants and anticoagulants are widely used agents, and in emergency or early cases, surgeons have to operate these patients. Both groups of drugs are growing, and in an emergency position, it is hard to know which drugs the patient using or given and what kind of medical status he/she has. For example non vitamin-K oral anticoagulants newer drugs and not known so much except cardiologists and cardiovascular surgeons. Simple solutions may have better results. Of course, in some conditions, urgent consultation can solve the problem. Cardiac surgeons have to figure out the problem by using their experience and surgical materials. Working as a team is a big advantage, more than one surgeon, experienced operation nurses and closer follow up in intensive care unit.
