[The early diagnosis of postoperative infectious complications in heart surgery patients].

Great surgical aggression in operations on the heart and resulting immunodeficiency create prerequisites for the appearance and grave course of infectious complications. The authors have analyzed results of operative treatment of 100 patients with acquired valvular diseases. It has been established that low parameters of the resistance index of organism (RIO) before operation can be estimated as an unfavourable prognostic sign of the development of infectious complications. The RIO dynamics at the postoperative period in many aspects reflects the character of its course. RIO and the indices of the adaptation reaction show the degree of intoxication, make the clinical estimation objective, allow the assessment of efficiency of therapy and correction of medical prescriptions.
