Dobutamine: IV medication given primarily for congestive heart failure from heart muscle weakening. This increases the ability of the heart to contract and increase blood flow throughout the body helping with heart failure symptoms. Used with diuretic therapy (Lasix) to get extra fluid/water out of the body. Used in hospital but can be used at home for chronic therapy for end-stage heart failure. ...Read more
Yes: But they should obviously run on different pumps so that they can each be titrated. ...Read more
Dobutamine: Dobutamine is a medicine used by physicians to increase blood pressure usually in a heart that does not pump well. It may be used when a patient is in heart failure or has had a heart attack and works by helping the heart to beat stronger and faster. It is given intravenously by an infusion and has a range of doses. Sometimes it is used as a stress test in patients who cannot exercise. ...Read more
Best to ask a nurse: Physician training and nurse training are very different. From a physician's perspective, I would want a nurse to monitor vital signs and cardiac telemetry. Nurses would obviously want to check on IV site, drug mixture, drug compatibility (if infusing more than one drug), etc. ...Read more
Yes and no: They are both catecholamines, a specific type of chemical class. In the body, there are different type of receptors in tissues which bind catechols with different effects. Dopamine and doubtamine have different affinities for different receptors and thus can have different effects. Kind of like different types of baking sugars...They are all sugars but are used for special purposes and functions. ...Read more
No other form: Presently, there is no other form of Dobutamine on the market. Generally, when Dobutamine is used, one is seeking immediate action of the drug, if the drug was administered through just about any other route, it would take longer to act and the delay in action is not desirable. This of course excludes CHF patients on chronic Dobutamine pump, my first sentence is directed at them. ...Read more
Depends on dosing: Dobutamine is an agent that helps the weak heart pump better by stimulating beta receptors in the heart. At lower doses it doesn't affect the blood vessels but higher doses it can also lower the tone of the ateries and makes it easier for the heart to pump. This tone is aka systemic vascular resistence. By lowering the svr the cariac out put will increase. Nipride (nitroprusside) has no beta stim effects only svr. ...Read more
Heart test: A cardiac sonographer will place electrodes on ur chest attached 2 an EKG monitor that charts ur heart’s electrical activity. They will perform a resting ekg, measure your resting heart rate & take your blood pressure. A dr or nurse will give the Dobutamine into ur IV while the they continue 2 obtain echo images. It will cause your heart to react as if you were exercising, your heart will go fast. ...Read more
Drug induced stress: If exercise on a treadmill is not an option (too much stress on the heart) due to a person’s medical condition, may use an intravenous medication called dobutamine. Dobutamine causes heart to beat faster and will mimic the effects of exercise on the heart. Stress tests usually can be nuclear with radiotracer or with echocardiography. ...Read more
Dobutamine: We usually would not administer Dobutamine in a nursing home setting. It needs to be closely monitored and this monitoring is usually not possible in a nursing home. Dobutamine is usually given for acute hemodynamic instablity and this is again not usually a nursing home treatment. ...Read more
When usual efforts: Fail. Once diuretics and usual efforts fail, then pressure like Dobutamine are used. Typically this is done in ICU or ccu. ...Read more
Which is more accurate in detecting viability after mi, dobutamine tests or nuclear tests (rest)? Can results be erroneous that should be repeated?
Depending on the institution, usually rest delayed thallium or FDG pet is performed to evaluate for myocardial viability.
Alternatively Dobutamine may be used. Low-dose Dobutamine infusion may result in potentiation of regional lv function in areas of hibernating myocardium. High-dose Dobutamine infusion will result in worsening regional abnormalities secondary to ischemia. ...Read more
A screening test: Stress tests are largely done to identify patients at risk for heart attacks. For patients who cannot exercise due to arthritis or other reasons, Dobutamine is a drug that will mimic exercise, and allow a stress test to be done. It is not as good as exercise, but it is a reasonable alternative if exercise is not possible. ...Read more
