Norepinephrine [noradrenaline] must be avoided in the presence of hypertension and blood pressure and infusion rate must be monitored frequently. Noradrenaline [norepinephrine]-induced cardiac arrhythmias are more likely in patients with hypoxia or hypercapnia. Hypovolaemia should be corrected before starting noradrenaline [norepinephrine] infusion.
Norepinephrine [noradrenaline] may reduce placental perfusion throughout pregnancy and some consider that it and similar vasoconstrictor sympathomimetics are best avoided; also in late pregnancy and some consider that it and similar vasoconstrictor sympathomimetics are best avoided; also in late pregnancy noradrenaline [norepinephrine] provokes uterine contractions which can result in fetal asphyxia.
