Excerpt
Septic shock is associated with a relative deficiency of the endogenous stress hormone vasopressin. In shock states vasopressin binds to vasopressin receptors on vascular smooth muscle, producing intense vasoconstriction with minimal osmotic effects and resulting in increased blood pressure. Two recent meta-analyses report relative risks (RR) of short-term mortality in favour of vasopressin analogues compared to noradrenaline; however, using different methodologies, one group found this difference to be statistically significant (RR = 0.87, 95 % CI 0.77–0.99) [
1] and the other did not (RR = 0.91, 95 % CI 0.79–1.05) [
2]. The current Surviving Sepsis Campaign guidelines recommend that vasopressin may be added as an adjunct to noradrenaline in septic shock [
3]. This short review aims to give an overview of the latest clinical evidence about vasopressin. …
