Editing Haemodynamic drugs (section)

== '''Adjuncts''' ==

* Septic/neurogenic shock whose blood pressure fails to respond to volume resus
* Useful in maintenance of BP that has been lowered by GA or regional anaesthetic
* '''Vasopressin'''
** "ADH" - antidiuretic hormone
** Produces vasoconstriction by actions on vascular smooth muscle
** Often added to noradrenaline in severe septic shock - no survival benefit
** Promotes splanchnic vasoconstriction in variceal bleeding
* '''Phenylephrine'''
** Pure alpha agonist
** Useful in maintaining BP in patients with epidurals, but somewhat questionable in this circumstance
** Bradycardia, low cardiac output, renal hypoperfusion
