Скачать или смотреть Vasopressors and Inotropes explained | Alpha Vs Beta effects | Paramedic

Hi all,

My name is James, I am an advanced life support paramedic. I am currently doing my Masters in medical education. I am passionate about EMS and make these video's purely because I enjoy doing so and in the hopes that you all will enjoy them.


I still find it confusing, which one is which. Alpha or beta. I found making this helpful.

Dopamine vs NE: Same death rate, but dopamine had more negative effects.

Prehospital Resuscitation with Phenylephrine in Uncontrolled Hemorrhagic Shock and Brain Injury
Phen vs LR, LR has less secondary effects. (better blood to brain)

In shock, dopamine does no naturally increase. Adrenaline and NE do.

CardShock study
cardiogenic shock - adrenaline use is associated with excess organ injury and mortality
adrenaline was independently associated with 90-day mortality in CS

meta analysis of RCT
At present there are no robust and convincing data to support a distinct inotropic or vasodilator drug based therapy as a superior solution to reduce mortality in haemodynamically unstable patients with CS or low cardiac output complicating AMI.

Despite the frequent use of catecholamines which are administered in ∼90% of patients in CS,7 there is only limited evidence from randomized trials comparing catecholamines in CS. Furthermore, despite beneficial effects on haemodynamics, there are no randomized data showing a prognostic benefit.

adrenaline in CA, no improvement, only better rosc

We found no evidence of substantial differences in total mortality between several vasopressors.

Survival After Shock Requiring High-Dose Vasopressor Therapy more than 1mcg/kg/min (normal 0.01-0.03)
One in six patients with shock survived to 90 days after HDV
