METHOD FOR PREVENTION OF DIFFUSE INTRA- AND POSTOPERATIVE BLOOD LOSS IN SURGERY OF ABDOMINAL AORTA Russian patent published in 2015 - IPC A61K35/16 A61P7/08 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to cardiovascular surgery, and concerns preventing a diffuse intra- and postoperative blood loss in surgery of abdominal aorta. To this effect, performing the aortoiliac operations is combined with measuring preoperative antithrombin III; if the measured value is less than 87±3%, a thromboelastography is performed from the moment of an anaesthetic support started with determining a coagulation index. If the coagulation index is less than 2.89±0.25 as early as at the start of the stage of approaching the abdominal aorta, before any surgically significant blood loss, fresh-frozen plasma of the identical group in a min. amount of 600 ml is administered into the patient. If the following dynamic control shows a decrease of the coagulation index below 1.10±0.28, at least 600 ml of fresh-frozen plasma is additionally administered, providing thereby the coagulation index by the end of the operation not less than 0.52±0.27.

EFFECT: method provides effective prevention of intra- and postoperative blood loss by prevention of intraoperative homeostatic disorders.
