[Disorders of hemodynamics in the acute period of respiratory distress syndrome (Doppler echocardiography)].

An all-round study of the cardiovascular system in 90 neonates with respiratory distress using Doppler's echocardiography has revealed 5 varieties of hemodynamic disorders: hypovolemia, transitory dysfunction of the left and right ventricle myocardium, persistent pulmonary hypertension, functioning arterial canal. Each of the enumerated varieties of circulatory disorders manifested itself by the characteristic symptom complex. However, frequent combinations of the disorders with each other made the clinical diagnosis fairly difficult. Doppler's echocardiography permitted one to make noninvasive diagnosis and to appraise the gravity of circulatory disorders.
