Question | Answer |
Oxygen | given to patients with angina pectoris (acute severe chest pain). Causes vasodilatation and protects the tissues from hypoxia. Can b administeres through cannula or facial mask. |
Epinephrine | Sympathetic drug used to manage cardiac arrest because it increases heart contractibility. |
Isoproterenol (Isuprel) | Produces overall increase in heart rate and myocardial contractibility, but newer agents have replaced it in most clinical settings. |
Dopamine (Intropin) | Indicated and used in cases with hypotension. Causes vasocontriction (narrowing of blood vessel). Should be used at lowest dose that roduces adequate perfusion of vital organs. |
Beta Blockers: Propranolol, Metoprolol, Atenolol, and Esmolol | Reduce heart rate, blod pressure, myocardial contractibility,myocardial oxygen consumption which make them effective in treatment of angina pectoris & hypertension. |
Beta Blockers: Propranolol, Metoprolol, Atenolol, and Esmolol (Continued) | Useful in preventing atrial fibrillation, atrial flutter,paroxysmal supra-ventricular tachycardia. Adverse effects are hypotension, broncho spasm, and CHF. |
Lidocaine | Suppression of ventricular ectopy contractions. Excessive doses can produce neurological changes. In large doses it causes myocardia depression and circulatory depression. |
Verapamil | Used in treatment of paroxysmal supraventricular tachycardia,effetive in ending moe than 90% of episodes in adults and infants. Vigiant monitoring of blood pressure is recommended. |
Digitalis | Increases force of cardiac contraction and cardiac output. Has high toxicity and patients need monitoring for symptoms such as yellow vision, nausea, etc. |
Morphine Sulfate | Traditional drug for pain and anxiety associated with acute myocardial infarction. In high doses it can cause respiratory depression. Controlled substance and tendency for abuse and addiction. |
Nitroglycerin | Powerful smooth muscle relaxant effective in relieving angina pectoris . Headache is a common consequence and hypotension as well. |
