Abstract

Norepinephrine (NE) is recognized as a potent vasopressor used in septic shock to reverse hypotension. Whether NE still exerts a positive effect on cardiac contractility through beta-adrenergic stimulation is unclear since the sensitivity of beta-adrenergic receptors can be abnormally reduced in septic conditions. Our study was designed to address this issue at the early phase of septic shock.
