Efficacy of noradrenaline vs dopamine in septic shock with late onset sepsis in Preterm babies.: open label randomised control trial

Preterm neonates have lower levels of NE and dopamine immediately after birth than full-term neonates. While dopamine acts mainly through the release of NE from presynaptic vesicles, it’s effectiveness can succumb to the depletion of endogenous NE and an increased ratio of pulmonary and systemic artery pressure at high dopamine doses.Administration of dopamine at initial dosages lower than commonly recommended, followed by incremental increase in dose, may be associated with improved left ventricular performance with avoidance of undesirable tachycardia and arrhythmias.This evidence supports the trial of NE in preterm neonates with compromised hemodynamics.. Noradrenaline causes  significant improvement in fractional shortening and mean bold pressure.hemodynamics. Noradrenaline is a relatively safe and effective drug to use in the treatment of neonatal septic shock.Therefore to see the effect of norepinephrine in septic shock in preterm neonates and to compare those with dopamine study this will be caried out.
