NE Group (Fluid loading with early norepinephrine administration group) NE Group will receive ringer lactate bolus 20 ml/kg along with norepinephrine infusion at 0.1 mcg/kg/minute until MAP\>5 percentile. Additional fluid boluses of 10-20 ml/kg will be administered (up to a total of 60 ml/kg) until shock resolution or signs of fluid overload are observed, with or without continued norepinephrine infusion according to the treatment group

Fluid Group will receive ringer lactate bolus 20 ml/ kg only. Additional fluid boluses of 10-20 ml/kg will be administered (up to a total of 60 ml/kg) until shock resolution or signs of fluid overload are observed
