Application of norepinephrine in septic shock / 医学研究生学报

The inappropriate use of norepinephrine(NE) in hypovolemic shock may be deleterious with potentially adverse vasoconstriction and subsequent hypoperfusion.Dramatically,based on the sufficient fluid resuscitation,high doses of NE administered rather increases the blood flow and oxygen delivery during sepsis.The mechanism may contribute to the reverse of vascular hyporesponsiveness and realization of microcirculation resuscitation.However,the optimal time,dosage and combination of NE with other vasoactive agents still necessarites further investigation.
