Commence ECG monitoring
Daily requirement is 1 to 2 mEq/Kg/day
Levels of Serum potassiun and ECG changes:
6 mEq/L tall, peaked T waves
7 mEq/L flat or absent p wave, wide qrs complex, bradycardia
>7.5 mEq/L ventricular arrhythmias, sine wave pattern
Starship guidelines are good on this but cannot be followed fully as concerns insulin infusiom with 25% DW, because it has to be given via central line only.
Follow instead the algorithm of Children Hospital Lahore, where 10 % DW is used. We may give upto 12.5%DW only via peripherla iv line so as to prevent the risk of phlebitis.
