TL;DR: A significant increase in catecholamines could jeopardize myocardial protective measures during CPB, and the predominant humoral response to CPB appears to be adrenomedullary release of E.

TL;DR: Although differing somewhat, midazolam, like diazepam, provided rapid, hemodynamically stable induction of anesthesia in patients with ischemic heart disease, and it was found that patients in both groups responded to endotracheal intubation with transient increases in blood pressure, heart rate, and systemic vascular resistance, but the hemodynamic values spontaneously returned toward control levels within 2 to 5 minutes.

TL;DR: The data show that SNP infusion during thoracic aortic cross-clamping improves systemic and regional circulation above the occlusion but decreases MAPb and therefore blood flow below the Occlusion, which suggests that blood flow through organs and tissues below theOcclusion is pressure dependent.

TL;DR: During cardiopulmonary bypass cerebral blood flow, autoregulation seems present at 20 degrees C, and the data set indicates that flows of about 1.2 may be adequate despite limited reserves.

TL;DR: It is shown that esmolol can be used safely during anesthesia in patients with normal ventricular function to attenuate cardiac response to sympathetic stimulation and antagonizes the β-adrenergic effects of norepinephrine.
