Norepinephrine is a commonly used rescue medication with powerful vasoconstrictor effect, clinically used to rescue various types of shock, and maintenance of blood pressure after cardiopulmonary resuscitation.
Norepinephrine is an adrenergic receptor agonist drug with powerful vasoconstrictor effect, which is used in the treatment of rescue for the treatment of hypotension caused by extracorporeal circulation in acute myocardial infarction, hypotension after pheochromocytoma resection, shock caused by blood volume insufficiency, as well as the maintenance of blood pressure after resuscitation of cardiopulmonary arrest.
The powerful vasoconstrictive effect of this drug can sharply reduce the blood flow to vital organs, and prolonged use will cause tissue and organ ischemia, hypoxia and acidosis, and reduce the amount of cardiac return blood, so it is only used for rescue treatment, and cannot be used for a long time.
The drug can only be injected intravenously, and leakage of the liquid can cause local tissue necrosis, therefore, try to inject it centrally intravenously. If there is a whitening of the skin along the venous pathway, local injection of skin ulceration, cyanosis, redness and other manifestations need to be dealt with in a timely manner.
