| Vasopressors | |||||||||||||||||||||||||||||||||||||||||||||||||
| Norepinephrine | Dopamine | Vasopressin | Phenylephrine | Dobutamine | |||||||||||||||||||||||||||||||||||||||||||||
| Mechanism | *Mainly predominantα1 agonist (Vasoconstrictive) *some β1 agonist (↑contractility) | *Mainly predominant β1 agonist (↑ cardiac contractility) * some α1 agonist(Vasoconstrictive) | *V1 receptor of GIT vasculatures *Antidiuretic effects | *Pure α1 agonist(Vasoconstrictive) *No β1 | *Predominant β1 agonist (↑contractility) *β2 arterial smooth muscle (Hypotensive) | ||||||||||||||||||||||||||||||||||||||||||||
| Indication | *1st line in : *Septic shock *Cardiogenic shock *Undifferentiated shock | 2nd line septic shock | 2nd line septic shock | 1st line Neurogenic shock 3rd-4th line septic shock | *1st line cardiogenic shock * low output septic shock | ||||||||||||||||||||||||||||||||||||||||||||
| Dose | 1-30 mcg/kg/min | 1-20 mcg/min | 0.03 unit/min | 20-300 mcg/kg/min | 2.5-20 mcg/kg/min | ||||||||||||||||||||||||||||||||||||||||||||
| Complications | Tachyarrhythmia {less β1 effect} ( less than Dopamine ) | Arrhythmia (more β1) | *Coronary spasm *Splanchnic vasoconstriction | Reflex bradycardia (only α1) | Hypotension (β2) | ||||||||||||||||||||||||||||||||||||||||||||
| Cautions | Arrhythmia | *Not in cardiogenic shock *Arrhythmia *Ischemia induced cardiotoxicity | *Ischemic heart *Gut ischemia | *Bradycardia *Heart block | *Hypotension (add α1 agonist) | ||||||||||||||||||||||||||||||||||||||||||||
Do's
- Assess the cause of shock
- Always volume fluid resuscitation first
- Norepinephrine in undifferentiated shock.
