Pure Inotropes Inotropes work primarily to increase cardiac output; they increase stroke volume by improving cardiac contractility, as opposed to vasopressors, which increase blood pressure by increasing peripheral resistance 1.

Inotropes can lead to peripheral vasodilation and have a variable effect on blood pressure; their use often results in hypotension. For this reason, inotropes should only be used in patients after complete fluid resuscitation. In addition, increased cardiac contractility leads to increased myocardial oxygen consumption 2which can result in increased in-hospital mortality 3 and risk for myocardial infarction 1.

Because inotrope use is rife with complications, research is currently underway in an attempt to find alternative options 4, 5.

There are only two inotropes frequently used in the United States: Levosimendan is a calcium-channel sensitizer with equivalent efficacy to the dopamine and milrinone, and possibly lower morbidity and mortality 6.

Therefore, this article will focus on dobutamine and milrinone. A year-old female with a history of CHF presents to your emergency department in acute respiratory distress.

Her vital signs are: Bedside cardiac ultrasound demonstrates marked global hypokinesis. You are unable to wean the patient off BiPAP, so you decided to continue positive pressure ventilation while starting a pressor.

Which pressor should you use? Because it primarily stimulates beta-1 receptors, dobutamine confers predominantly inotropic effects, with less pronounced chronotropic effects. Therefore, dobutamine can lead to decreased blood pressure in some but not all patients. Due to its vasodilatory effects, dobutamine has been shown to improve capillary perfusion independent of changes in blood pressure and cardiac index As a catecholamine analog, dobutamine may be used through a peripheral catheter 7.

However, central access is strongly preferred. However, despite minimal chronotropic effects, studies have demonstrated increased myocardial oxygen demand and malignant arrhythmias 8, 11, Dobutamine use was found to substantially increase mortality at days when compared with placebo in the CASINO study As noted above, many patients experience hypotension associated with dobutamine use.

It should be used with caution in patients with systolic blood pressure less than 90 mmHg. For this reason, dobutamine should only be used in patients with adequate fluid resuscitation Therefore, negative effects of dobutamine are theoretically rapidly reversible.

In addition, dobutamine infusions lasting longer than 72 hours can lead to pharmacologic tolerance 1. This includes patients with known decreased ejection fracture and those who are persistently hypotensive despite adequate fluid administration and use of vasopressors.

However, because dobutamine can lower blood pressure, it should only be used if systolic blood pressure is between mmHg, with norepinephrine ready or already infusing as well.

Dobutamine is typically recommended as the first line agent in cardiogenic shock 17but this is not a strong recommendation because several studies have demonstrated benefits to norepinephrine in this setting 18, If dobutamine is used as a first-line agent, then norepinephrine should be second-line or already infusing, followed by milrinone.

You are treating a year-old female in acute decompensated heart failure. You are currently attempting to provide positive pressure ventilation while using pressors to maintain hemodynamic stability. You previously initiated a dobutamine drip, and then added norepinephrine. What can do you do now?

PDE3 is present in cardiac myocytes and vascular smooth muscles; it ultimately leads to cardiac smooth muscle relaxation and peripheral vasoconstriction 1, 9. Therefore, PDE3 inhibition results in potent inotropy, in addition to diastolic relaxation and vasodilation.

This leads to reduced preload, afterload, and systemic vascular resistance SVR. In addition to increased cardiac contractility, this results in improved cardiac output. Milrinone has no beta-adrenergic activity, resulting in minimal chronotropic effects.Value-based healthcare is a healthcare delivery model in which providers, including hospitals and physicians, are paid based on patient health outcomes.

Under value-based care agreements, providers are rewarded for helping patients improve their health, reduce the effects and incidence of chronic. That said, many believe they cause inflammation or toxicity.

Most arguments are based on certain chemicals found in nightshades, although these are also present in many other healthy foods. David Sackett, MD, a Canadian physician, is considered the father of evidence-based practice, according to Cheryl Fisher, MSN, RN, program manager for professional practice development of nursing and patient care services at the National Institutes of Health (NIH) Clinical Center.

To that end, evidence-based patient care becomes a lifelong approach to clinical decision making to improve clinical outcomes and includes use of best evidence, clinical expertise, and values of patients and their families.

Successful implementation of evidence-based practice (EBP) can bring a number of patient care benefits to healthcare facilities.

Unfortunately, keeping staff nurses engaged can be an uphill battle.
