Efficacy of dobutrex was assessed in 75 patients with grave poisonings. In 45 of these poisoning with cardiotoxic agents was complicated by acute heart failure and in 30 poisoning with psychopharmacological agents involved secondary disorders of cardiac contractile function. A sharp reduction of cardiac contractile function and output were observed in all the cases. Treatment efficacy was assessed by monitoring the parameters of central hemodynamics and by phase analysis of left-ventricular systole by rheopolycardiography with recording by mingograf-82. The results indicated a rapid and effective correction of decreased cardiac contractility and increase of cardiac output. The dose-effective concentration of dobutrex in the blood needed for the treatment of acute heart failure was from 10 to 17.5 micrograms/kg/min. Arterial pressure, cardiac contractility, and cardiac output stabilized within 4 to 6 h. After poisoning with psychopharmacological agents cardiac contractility recovered in 3-3.5 h. The dose-effective concentration of dobutrex in the blood was 5 micrograms/kg/min. Dobutrex is a highly active cardiotonic agent for the treatment of critical states developing in the aforesaid poisonings.

The paper deals with the development of a diagnostic and therapeutic algorithm of intraoperative heart failure during cardiosurgical operations on the basis of evaluation of systolic and diastolic functions of the left and right ventricles. The study included 101 patients with low cardiac output in the postperfusion period. All the patients suffered from coronary heart disease and they underwent myocardial revascularizing operations under extracorporeal circulation. In all the patients, in addition to traditional hemodynamic parameters (heart rate, blood pressure, central venous pressure), the functional status of the left and right ventricles was evaluated by transesophageal Doppler echocardiography (TED echoCG) and the thermodilution technique using a Swan-Ganz catheter having a prompt thermistor. Evaluating the diastolic and diastolic functions of the right and left ventricles makes it possible to identify 2 types of left and right ventricular failure: 1) that due to systolic dysfunction and 2) that due to concomitance of systolic and diastolic dysfunctions. Dobutrex (5-7.5 microg/kg/min) should be used in right ventricular systolic dysfunction. Amrinone (5-10 microg/kg/min) should be given to patients with concomitance of systolic and diastolic dysfunction; in this situation, a combination of dobutrex and nitroglycerin (100-150 ng/kg/min) may be used. The drugs of choice in impaired left ventricular systolic function are epinephrine (30-100 ng/kg/min), dopamine (5-10 microg/kg/min), or dobutrex (5-7.5 microg/kg/min). Their combination with sodium nitroprusside can enhance the efficiency of therapy. In patients with left ventricular failure caused by systolic and diastolic dysfunction, epinephrine, dopamine, or dobutrex may be combined with amrinone (5-10 microg/kg/min) or nitroglycerin (100-150 ng/kg/min).
