Early Sodium Intake in Preterm Newborns

Phase 4
Completed
Conditions
Hyponatremia
Premature
Interventions
Drug: Sodium < 1mEq/kg/day
Drug: Sodium 5mEq/kg/day
Registration Number
NCT04035564

Hospital del Niño "Dr. Federico Gomez Santos"
Brief Summary

Hyponatremia is a common complication among preterm infants, renal losses of sodium contribute to the development of hyponatremia in preterm newborns. Sodium imbalances impact in newborns outcome. There is controversy about the time of initiation and the requirements of sodium in premature infants. Hypothesis: early (24 hours of life) sodium supplementation (5mEq/kg/day) prevents the develop of hyponatremia in preterm infants.

Detailed Description

This study is a randomized controlled trial in infants less than 35 weeks gestation admitted to the Newborn Intensive Care Unit at Children Hospital in Saltillo Coahuila Mexico.

Infants receive at 24 hours of life; sodium (5mEq/kg/day) versus less than 1mEq/kg/day. Weight, serum and urine sodium, serum chloride, serum and urine creatinine, serum chloride, bicarbonate and glucose are monitored daily during the first 3 days of life. Patients are assessed for hyponatremia, hypernatremia, weight change, sepsis, necrotizing enterocolitis and intraventricular hemorrhage.

Number of Participants With Late-onset SepsisPatients will be followed during hospitalization, an expected average of 3 months of age

Positive blood culture and/or 5 days of continuous antimicrobial therapy

Change in Serum SodiumInitial serum sodium (baseline) vs 72 hours

Number of Participants With Intraventricular HemorrhagePatients will be followed during hospitalization, an expected average of 3 months of age

Bleeding into the brain´s ventricular system (intracranial ultrasound).

Weight ChangeInitial weight (baseline) vs 72 hours

The difference between current weight and initial weight

Number of Participants With Necrotizing EnterocolitisPatients will be followed during hospitalization, an expected average of 3 months of age

Number of patients with Bell stage II or greater necrotizing enterocolitis

Bell's Staging:

Stage II A:

Gastrointestinal signs: Increasing gastric aspirates, mild abdominal distention, fecal occult blood, absent bowel sounds.

Systemic signs: Temperature instability, apnea, bradycardia, lethargy. Radiological findings: Intestinal dilatation, ileus, pneumatosis intestinalis.

Stage II B:

Gastrointestinal signs: As stage IIA plus abdominal tenderness. Systemic signs: As stage IIA plus metabolic acidosis and thrombocytopenia. Radiological findings: As stage IIA plus portal vein gas and ascites.

Stage III A:
