Simultaneous dopamine and sodium nitroprusside therapy following open heart surgery.

Twenty post-open heart surgery patients with low output syndrome were given dopamine, sodium nitroprusside (SNP) alone and in combination. Dopamine alone (3--4 mcg/Kg/min) caused an increase of cardiac output (CO) from 3.2 to 4.

Hemodynamic parameters were measured in 80 unselected patients prior to cardiopulmonary bypass for a variety of a operative procedures. Isovolemic blood withdrawel up to 24.7 ml/kg or 10 gms% and 30% hematocrit during sternotomy using ACD blood storage containers was carried out prior to bypass.

Haemodynamic measurements were made in 80 patients who underwent acute haemodilution (up to 40 ml/kg blood withdrawal) before cardiopulmonary bypass. Measurements of cardiac output, pulmonary arterial pressures including wedge pressure were made. Cardiac index, stroke volume and total peripheral resistance were calculated.
