Primary Outcome Measures:
  • incidence of nephrocalcinosis in extremely preterm infants [ Time Frame: 38-40 weeks of corrected gestational age ]
    incidence of nephrocalcinosis in extremely preterm infants


Secondary Outcome Measures:
  • Determine whether the administration of potassium citrate in extreme premature decreases neonates the levels of calcium and calcium / creatinine ratio in urine in each of the branches of treatment at 38-40 weeks [ Time Frame: 38-40 weeks of corrected gestational age ]
    Determine whether the administration of potassium citrate in extreme premature decreases neonates the levels of calcium and calcium / creatinine ratio in urine in each of the branches of treatment at 38-40 weeks

  • To determine whether administration of potassium citrate improves the levels of urinary phosphorus, potassium, sodium, citrate, creatinine, oxalate, ratio citrate / calcium , and ph value [ Time Frame: 38-40 weeks of corrected gestational age ]
    To determine whether administration of potassium citrate in extreme premature infants improves the levels of phosphorus, potassium, sodium, citrate, creatinine, oxalate, and ratio citrate / calcium and ph in urine in each treatment arm at the 38-40 weeks.

  • Determine whether the administration of potassium citrate improves the plasma levels of sodium, potassium, creatinine, calcium, and ph value. [ Time Frame: 38-40 weeks of corrected gestational age ]
    Determine whether the administration of potassium citrate in extreme premature neonates improves the plasma levels of sodium, potassium, creatinine, calcium, and blood ph value in each of the branches of treatment at 38-40 weeks.

  • To determine the incidence of adverse events and serious adverse events related to study treatment. [ Time Frame: 38-40 weeks of corrected gestational age ]
    To determine the incidence of adverse events and serious adverse events related to study treatment.

Study Start Date: January 2013
Estimated Study Completion Date: January 2014
Estimated Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Potassium citrate
Potassium citrate, oral solution contains Tripotassium citrate monohydrate 20 grams, Citric acid monohydrate 4 grams, distilled water 40 ml, and simple syrup 100ml. The solution contained in a bottle of glass that contains 20 ml of 2 meq/ml of potassium and 2.5 meq/ml of citrate. The dose is 0,3ml/kg/day of the solution until the 38-40 weeks of corrected gestational age.
Drug: Potassium Citrate
Potassium citrate, oral solution contains Tripotassium citrate monohydrate 20 grams, Citric acid monohydrate 4 grams, distilled water 40 ml, and simple syrup 100ml. The solution contained in a bottle of glass that contains 20 ml of 2 meq/ml of potassium and 2.5 meq/ml of citrate. The dose is 0,3ml/kg/day of the solution until the 38-40 weeks of corrected gestational age or unacceptable toxicity develops.
Placebo Comparator: Placebo
Oral solution 30ml, that contains distilled water and simple syrup, in the same dose like the active treatment 0,3ml/kg/day.
Drug: Placebo
