Abstract: Изобретение относится к медицине, а именно к абдоминальной хирургии, травматологии и реаниматологии, и может быть использовано для оценки течения раннего послеоперационного периода у больных, оперированных по поводу различных заболеваний и повреждений. В способе прогнозирования тромбоэмболических послеоперационных осложнений осуществляют забор и анализ венозной крови у больного. В раннем послеоперационном периоде в динамике в крови определяют значение Международного нормализованного отношения, содержание малонового диальдегида и лизоформ фосфолипидов. На основе полученных данных рассчитывают индекс прогнозирования тромбоэмболических послеоперационных осложнений (ИПТПО) по формуле:где MNO– Международное нормализованное отношение в предыдущий момент, MNO– Международное нормализованное отношение в текущий момент, MDA– содержание малонового диальдегида в текущий момент, MDA– содержание малонового диальдегида в предыдущий момент, LF– содержание лизоформ фосфолипидов в текущий момент, LF– содержание лизоформ фосфолипидов в предыдущий момент. Значение ИПТПО менее 3,0 свидетельствует об отсутствии вероятности развития тромбоэмболических осложнений, значение ИПТПО от 3,1 до 4,4 констатирует низкую вероятность развития тромбоэмболических осложнений, значение ИПТПО более 4,5 констатирует высокую вероятность развития тромбоэмболических осложнений. Изобретение обеспечивает повышение точности и адекватности оценки состояния свертывающей системы крови у больных в раннем послеоперационном периоде. 5 табл., 4 пр.
