Dopaminergic (1-2 mcg/kg per min): cerebral, renal, and mesenteric vasodilation increase urine output 4. Mixed alpha and beta-1 (2-10 mcg/kg per min): increases cardiac ouput with moderate increase systemic vascular resistance 5. Predominantly alpha (>20 mcg/kg per min): increases systemic vascular resistance Uses: 1. Treat hypotension associated with bradycardia 2. Stimulate cardiac output and urine output Dose: 1. Start infusion at 1-5 mcg/kg per min and titrate to effect. 2. Use the lowest dose that provides the desired hemodynamic improvement. 3. Do not exceed 20 mcg/kg per min. Potential complications: 1. May increase pulmonary pressure and worsen pulmonary congestion. 2. May increase myocardial work without improving coronary blood flow, exacerbating myocardial ischemia 3.

| 3-hydroxybutyrate dehydrogenase |
[EC 1.1.1.30] an enzyme of the oxidoreductase class that catalyzes the oxidation of D-3-hydroxybutyrate to form acetoacetate, using NAD+ as an electron acceptor. The enzyme functions in nervous tissues and muscles, enabling use of circulating hydroxybutyrate as a fuel. In the liver mitochondrial matrix, the enzyme can also catalyze the reverse reaction, a step in ketogenesis. Written also β-hydroxybutyrate dehydrogenase.
