OBJECTIVE: Evaluate the impact of a sodium (Na) supplementation protocol based upon urine Na concentration on growth parameters and morbidities.
STUDY DESIGN: Retrospective cohort study of infants 260/7-336/7 weeks gestational age (GA) cared for before (2012-15, n = 225) and after (2016-20, n = 157) implementation of the protocol. Within- and between-group changes over time were assessed using repeated measures generalized linear models.
RESULTS: For infants 260/7-296/7 weeks GA, utilization of the protocol was associated with increased mean body weight z-score at 8-weeks postnatal age, increased mean head circumference z-score at 16-weeks postnatal age, and decreased time on mechanical ventilation (all p < 0.02). No impact on growth was identified for infants 30-336/7 weeks GA. Incidences of hypertension, hypernatremia, bronchopulmonary dysplasia, and culture positive sepsis were unaffected by the protocol.
CONCLUSION: Protocolized Na supplementation results in improved growth and reduced time on invasive mechanical ventilation in extremely preterm infants without increasing incidence of morbidities.
