The Hemodynamic Effects of Drugs on Myocardial Oxygen Use
The circulatory responses to high equinalgesic doses of morphine are compared with those of pethidin. The decrease in mean arterial blood pressure in case of morphine was 28p.c., with a paralleled and identical decrease in total peripheral resistance and no negative inotropic effects. Pethidine decreased blood pressure 54p.c., as a result of peripheral vasodilation of 46p.c. and a sharp drop...
متن کاملHemodynamic studies of patients with myocardial infarction.
Cardiac output, venous and arterial pressure, total peripheral resistance and blood volume were measured in patients with acute myocardial infarction, with and without shock, and on recovery, and in patients without heart disease. Cardiac output falls to below normal after myocardial in-farction, and rises significantly, though not always to normal, on recovery. Cardiac output was very low when...
متن کاملHemodynamic effects of nitroglycerin in acute myocardial infarction.
Nitroglycerin (NTG) has recently been suggested to decrease myocardial ischemia and enhance cardiac pump function during acute myocardial infarction (AMI). To evaluate the sublingual agnet in this condition, the hemodynamic effects of 0.4 mg NTG administered to 16 supine patients during the first 72 hours of AMI were determined serially 5, 10 to 15, and 20 to 30 minutes post-NTG. Data were eval...
متن کاملSequential cardiorespiratory events during and after dextran-40 infusion in normal and shock patients.
Sequential measurements of cardiac output, intravascular pressures, blood gases, pH, blood volume, and oxygen consumption were made in normal subjects and patients in shock before, during, and after infusions of dextran-40. In eight normal subjects the responses were: increased central venous pressure, increased cardiac index, decreased peripheral resistance, and decreased hemoglobin concentrat...
متن کاملHemodynamic studies in cardiogenic shock. Treatment with isoproterenol and metaraminol.
In 14 subiects with severe cardiogenic shock the characteristic findings before treatment were hypotension, low cardiac output, and increased central venous pressure, with normal values for total peripheral resistance. Oliguria, lactic acidosis, hypocapnia. and hypoxemia also were present. These changes were interpreted as reflecting acute heart failure in association with a peripheral vascular...
