Echocardiographic assessment of coronary blood flow velocity during controlled hypotensive anesthesia with nitroglycerin.
To determine the effect of nitroglycerin on coronary blood flow velocity during controlled hypotensive anesthesia in humans. ⋯ During nitroglycerin-induced hypotensive anesthesia, coronary blood flow as assessed by peak diastolic left anterior descending flow velocity is preserved or increased in most patients. Increases in left anterior descending flow velocity are predictably achieved only at nitroglycerin doses >5 microg/kg/min. Intraoperative transesophageal echocardiography is useful in monitoring coronary flow velocity responses to controlled hypotensive anesthesia.

Temporal synthesis and release of endothelin within the systemic and myocardial circulation during and after cardiopulmonary bypass: relation to postoperative recovery.
To determine endothelin levels in arterial, pulmonary, and myocardial vascular compartments in patients undergoing coronary artery bypass graft surgery and to examine the influence of endothelin on postoperative recovery. ⋯ Endothelin levels after CPB remained persistently increased for at least 24 hours after surgery and were associated with increased myocardial production of endothelin. These results suggest that the increased endothelin observed in the early postoperative period may contribute to a complex recovery from coronary artery bypass graft surgery.

Parameters associated with perioperative baffle fenestration closure in the Fontan operation.
To identify clinical parameters indicating perioperative fenestration closure in children who underwent the fenestrated Fontan operation. ⋯ Factors that correlated with postoperative fenestration closure in the fenestrated Fontan operation in this study were a high transpulmonary pressure gradient and a high oxygen saturation 1 hour after arrival in the ICU, a low fibrinogen level, and the need for temporary atrial pacing.

Randomized Controlled Trial Comparative Study Clinical TrialHemodynamic effects of milrinone during weaning from cardiopulmonary bypass: comparison of patients with a low and high prebypass cardiac index.
To compare the hemodynamic effects of milrinone during weaning from cardiopulmonary bypass (CPB) in patients with a low pre-CPB cardiac index (CI) <2.5 L/min/m2) and in patients with a high pre-CPB CI (> or =2.5 L/min/m2). ⋯ Milrinone was effective during weaning from CPB in patients with a low pre-CPB CI. Milrinone in combination with norepinephrine was a good alternative to epinephrine for the treatment of myocardial dysfunction after CPB.
