dopamine vs epinephrine in cardiogenic shock
Mortality is about 50%. Digoxin vs. Dopamine. Disadvantages of dopamine compared to epinephrine: 1) Dopamine can cause skin necrosis with prolonged infusion. Resolution of shock was achieved in similar numbers in both the groups (milrinone 76% vs dobutamine 70%, P = .50). Understanding prehospital vasopressors: Dopamine, epinephrine or norepinephrine? 2011; 39 : 450-455 [Brierley, 2009] Adult literature has raised concerns about safety of Dopamine [De Backer, 2010] Dopamine is known to not be as effective in young children (<6 months). It functions as an a … The most widely accepted classification system organizes shock into four broad categories: (1) Hypovolemic, (2) cardiogenic, (3) obstructive, and (4) distributive ().Patients who are in HS often have overlap between these categories, but determining which form shock is primarily involved is helpful for further diagnosis and treatment. ; Epinephrine: Viable alternative as increases cardiac contractility and blood pressure but also exacerbates myocardial … A recently published meta-analysis compared dopamine versus norepinephrine in the treatment of cardiogenic shock. Norepinephrine or dopamine is preferred over epinephrine as a vasoconstrictor in cardiogenic shock due to the association of the latter with increased mortality, and higher levels of lactate, renal impairment, and myocardial necrosis markers 38. The authors here decided to take a look at norepinephrine (NE) versus epinephrine in patients with cardiogenic shock s/p MI. Objective: There is no study that has compared, in a randomized manner, which vasopressor is most suitable in optimizing both systemic and regional hemodynamics in cardiogenic shock patients. Notably, an increased death rate was observed in the subgroup of patients with cardiogenic shock treated with dopamine.) For the primary efficacy endpoint, cardiac index evolution was similar between the 2 groups (p = 0.43) from baseline (H0) to H72. Norepinephrine It also increased mortality compared to epinephrine among septic children (Ventura 2015). The use of an intra-arterial catheter is helpful in managing patients in cardiogenic shock. The main advantage of dopamine is that it's stable at room temperature, so it may be more widely available in pre-mixed bags (e.g. 13 Norepinephrine was associated with decreased 28-day mortality, a lower risk of arrhythmias and less gastrointestinal adverse effects. This study compared norepinephrine to dopamine and found a mortality benefit among the cardiogenic shock subgroup treated with norepinephrine. However, it is unclear what data these recommendations are based upon. Short answer = there is no perfect vasopressor and no perfect answer. 26,27 Dobutamine at a rate of 5 20 mcg/kg per minute IV infusion may be given to improve cardiac output. The use of dopamine in the setting of cardiogenic shock has been commonplace, but this approach has come under some scrutiny after studies showing increased arrhythmias with patients in shock. Dopamine and Dobutamine are dose specific. Levophed is primarily a, but also has some b1. ... means it is the recommended agent for anaphylactic shock [8]. in ambulances). Usually, a vasoconstrictor is administered concomitantly to ensure adequate perfusion pressure. Cardiogenic shock is more nuanced. Once the etiologic treatment has been done, for instance coronary revascularization, management of the shock state is the cornerstone of the treatment. SOAP II trial — norepinephrine as first line agent in patients with shock was associated with less arrhythmia vs. dopamine [in the CS subgroup] There has been a small randomized trial comparing norepinephrine vs epinephrine in cardiogenic shock from MI (Pump Dysfunction) and found that norepinephrine was superior to epinephrine. Dobutamine (beta-1/2 agonist activity) – may augment cardiac output but also causes vasodilation and may lead to a significant BP drop Norepinephrine: Superior to dopamine in undifferentiated shock and in subgroup with cardiogenic shock (De Backer 2010). Design: Open, randomized interventional human study. Setting: Medical intensive care unit in a university hospital. both systemic and regional hemodynamics in cardiogenic shock patients. Dopamine is also potent in helping with renal perfusion by opening the renal tubules and allowing perfusion in the kidneys. You need to look at your drugs' stimulation and what kind of shock your pt is in. Comparison of norepinephrine-dobutamine to epinephrine for hemodynamics, lactate metabolism, and organ function variables in cardiogenic shock: a prospective, randomized pilot study. We use cookies to offer you a better experience, personalize content, tailor advertising, provide social media features, and better understand the use of our services. For the main safety endpoint, the observed higher incidence of refractory shock in the epinephrine group (10 of 27 [37%] vs. norepinephrine 2 of 30 [7%]; p = 0.008) led to early termination of the study. Cardiogenic shock is a frequent cause of admission and death in the intensive care unit. Dopamine vs Epinephrine •Design: prospective RCT, 01/02/2009 - 31/07/2013 •Setting: PICU, Universidade de São Paulo, Brazil •Patients: children 1m-15y fluid-refractory septic shock They didn’t use dopamine as they had noted an article that I have reference here where I discussed how dopamine actually increases mortality in cardiogenic shock compared to NE. Traditional teaching and prior guidelines have listed Dopamine as 1st line therapy. Where Neo is all a. Dopamine possesses a variety of useful pharmacologic properties. Epinephrine vs Dopamine. Classification of HS. Changes in hemodynamic parameters from baseline and adverse events were also assessed. Dopamine (3,4 dihydroxy phenylethylamine) is a naturally occurring catecholamine that has been employed both experimentally and clinically for the therapy of various forms of shock. Crit Care Med. 2) At high doses, dopamine may act predominantly as a vasoconstrictor. However, the AHA guidelines expressed some reservations about the study’s vague definition of cardiogenic shock and the heterogenous subtypes of cardiogenic shock. Patients given epinephrine were more likely to develop refractory cardiogenic shock, which led to early termination of the study. (A contemporary multicenter RCT examining dopamine vs. norepinephrine as first-line vasopressor therapy in shock patients, and showing no significant difference in death rates but more adverse events with the use of dopamine. The American Heart Association recommends dopamine be the 1 st line pressor in normotensive pediatric septic shock, norepinephrine in hypotensive, “warm” shock (those with good cardiac function) and epinephrine in hypotensive “cold” shock (those with cardiac depression). Remember you have a1, a2, b1, b2, d1, & d2 stimulation. Both dopamine and epinephrine can provide vasopressor and inotropic actions [23,24,25].Vasopressors serve as the first-line vasoactive drugs in the management of neonatal septic shock because of decreased systemic vascular resistance [26, 27].Dopamine is recommended to be the first-line vasoactive agent in fluid-refractory septic shock [].It is also the first-line vasoactive drug in … Among the 280 patients with cardiogenic shock, dopamine was linked to a higher death rate at 28 days (P = .03 for cardiogenic shock) but was not in 1044 patients with septic shock (P = .19) and 263 patients with hypovolemic shock (P = .84). Dopamine is also an inotropic drug because it helps with forceful heart contractions. Hence, the present study was designed to compare epinephrine and norepinephrine-dobutamine in dopamine-resistant cardiogenic shock.. Design: Open, randomized interventional human study. Dopamine increases mortality in RCTs: Dopamine increased mortality compared to norepinephrine in the subgroup of patients with cardiogenic shock (De Backer 2010). The primary end point was the time to resolution of cardiogenic shock. Dopamine has traditionally been the drug of choice, owing to its vasopressor and inotropic activity. In a subgroup analysis, dopamine was associated with an increased rate of 28-day mortality among the 280 patients with cardiogenic shock, but not among patients with septic or hypovolemic shock. Unlike other inotropic drugs, dopamine directly dilates the mesenteric, renal, and cerebral vessels and … Dopamine is a direct-acting catecholamine with a short half-life that has many advantages in treating visceral hypoperfusion states such as shock and refractory heart failure. Dopamine vs. Norepinephrine in Treatment of Shock. Epinephrine is an agonist of alpha1, beta1, and beta2 receptors. A predefined subgroup analysis according to type of shock showed that among 280 patients with cardiogenic shock, the death rate at 28 days was significantly higher in dopamine recipients than in norepinephrine recipients. the development and cause of cardiogenic shock to prevent the associated high morbidity and mortality (4). Now epi is primarily b1. Hence, the present study was designed to compare epinephrine and norepinephrine-dobutamine in dopamine-resis-tant cardiogenic shock. Dopamine is extremely helpful for patients experiencing acute renal failure. The use of dopamine was associated with a greater number of adverse events in the overall population and an unexpected increase in the rate of death in the subgroup of patients with cardiogenic shock. ... (24% vs. 12%).
