Hypernatremia elbw

OBJECTIVES: Sodium homeostasis in extremely low birth weight (ELBW) infants is critical. While a lack of sodium delays growth, excessive supplementation increases morbidity. METHODS: We performed a single-center retrospective study on sodium and fluid management during the first 2 weeks of live including all ELBW infants born between June 1, 2017 and May 31, 2019. RESULTS: Forty-seven patients (median GA 26 + 6 weeks, median BW 845 g) were included...

BACKGROUND: To determine total sodium load, including inadvertent load, during the first 2 postnatal weeks, and its influence on serum sodium, morbidity, and mortality in extremely low birth weight (ELBW, birth weight <1000 g) infants and to calculate sodium replacement models. METHODS: Retrospective data analysis on ELBW infants with a gestational age <28 + 0/7 weeks. RESULTS: Ninety patients with a median birth weight of 718 g and a median gestational age of 24 + 6/7 weeks were included...

OBJECTIVE: The objective of this study is to discern patterns of serum sodium in a broad cohort of extremely low birth weight (ELBW) infants and associate those patterns with hospital outcomes. STUDY DESIGN: Retrospective cohort study of ELBW infants from 323 neonatal intensive care units (NICUs) discharged from 2004 to 2014. We included patients who survived at least 7 days and had daily sodium levels available, and categorized infants by their minimum and maximum sodium levels...

Hypernatremic dehydration is an important cause of intracranial hemorrhage. A possible association of intraventricular hemorrhage (IVH) with hypernatremia and/or high sodium intake has been suggested in preterm infants. To investigate the associations of early fluid and sodium intake or serum sodium concentrations with severe intraventricular hemorrhage (IVH) in extremely low birth weight (ELBW) infants, we reviewed the medical records of 169 inborn ELBW infants. Daily fluid and sodium intake, urine output, weight loss and serum sodium concentration during the first 4 days of life were obtained...

OBJECTIVE: To identify changes in temperature, fluid and electrolyte management, growth, and short-term outcome in extremely low birth weight (ELBW) infants nursed in humidified hybrid incubators (HI group) compared with a cohort of patients cared for in nonhumidified conventional incubators (CI group). METHODS: Body temperature (BT), fluid and electrolyte balance, and growth velocity (GV) were collected retrospectively on 182 ELBW infants. The CI group included ELBW infants cared for with radiant warmers followed by an incubator without humidity...

This study was performed to test the hypothesis that sterile water gavage drip (SWGD) used in the fluid management of extremely low birthweight (ELBW) infants will decrease the incidence of hypernatremia. Secondary hypotheses included decreased hyperkalemia, hyperglycemia, and hyperbilirubinemia. Sixty ELBW infants were randomized before 36 hours of age to receive SWGD (up to 30 mL/kg/d) and intravenous fluid or conventional intravenous fluid management. SWGD was well tolerated in 89% of the infants. No difference was seen in the incidence of hypernatremia, hyperkalemia, hyperglycemia, or hyperbilirubinemia...

OBJECTIVE: Significant fluid and electrolyte disturbances occur in extremely low birth weight (ELBW) infants in the first few days of life. We investigated the effect of semipermeable polyurethane membrane (Tegaderm) applied to the skin shortly after birth on fluid and electrolyte status and the clinical outcome in these infants. STUDY DESIGN: We reviewed charts of ELBW infants (BW<1.0 kg) born during 24 months prior to Tegaderm application and 19 months after starting Tegaderm...

Hyperkalaemia is a life-threatening electrolyte disorder that can occur in the first week of life in almost 50% of preterm infants with a birth weight less than 1000 g [extremely low birth weight (ELBW)]. Serum potassium values higher than 7 mmol x l-1 are associated with cardiac arrhythmias and an increased incidence of intraventricular haemorrhage and periventricular leucomalacia. Therapeutic options to treat this dangerous imbalance comprise calcium gluconate, insulin plus glucose, albuterol/salbutamol inhalation...

OBJECTIVE: To compare fluid and electrolyte management in extremely low birth weight (ELBW) infants nursed in humidified versus nonhumidified incubators. STUDY DESIGN: Setting--tertiary intensive care nursery. Subjects--all infants with birth weight < 1000 g admitted 1/95 to 1/99 who were treated with incubators and survived for > 96 hours (N = 155). Intervention--retrospective comparison of daily weights, fluid intakes, urine outputs, and serum electrolytes between group 1 (n = 70, nonhumidified incubators, born 1/95 to 1/97) and group 2 (n = 85, humidified incubators, born 1/97 to 1/99) over the first 4 days after birth...

There are few reported studies of water balance and electrolyte abnormalities in extremely low birthweight (ELBW) infants weighing < 1000 g nursed in high humidity. We retrospectively analyzed water balance, electrolyte and acid-base balance in 100 ELBW infants, of whom 72 were appropriate for gestational age (AGA) and 28 were small for gestational age (SGA). They were cared for in closed incubators at almost full ambient humidity. Fluid intake was restricted to 50-60 mL/kg on the first day of life and was adjusted to maintain normal serum Na concentration...
