Controlled trial of bicarbonate therapy in high-risk premature newborn infants
Insights
Sodium bicarbonate treatment in acidemic premature newborns did not improve pH correction or reduce mortality. This intervention showed a slight increase in deaths and similar rates of intraventricular hemorrhage compared to no bicarbonate.
Area of Science:
- Neonatal Medicine
- Pediatric Critical Care
- Biochemistry
Background:
- Premature infants often experience metabolic acidosis.
- Acidosis in newborns can lead to serious complications.
- Current treatment strategies for neonatal acidosis are debated.
Purpose of the Study:
- To evaluate the efficacy of sodium bicarbonate in treating acidemic premature newborns.
- To determine if liberal sodium bicarbonate administration improves pH correction and reduces mortality.
- To assess the impact of sodium bicarbonate on intraventricular hemorrhage incidence.
Main Methods:
- A randomized controlled trial involving 62 high-risk acidemic premature newborns.
- Infants received maintenance intravascular infusions of 10% glucose.
- Treatment groups were assigned to liberal or restricted sodium bicarbonate administration based on acidosis severity.
Main Results:
- Sodium bicarbonate did not lead to more rapid correction of pH.
- Mortality rates were not decreased in the bicarbonate treatment groups.
- A slight increase in deaths was observed in infants receiving bicarbonate.
- The incidence of intraventricular hemorrhage was similar between groups.
Conclusions:
- Liberal administration of sodium bicarbonate is not beneficial for acidemic premature newborns.
- This treatment does not improve pH normalization or survival rates.
- Sodium bicarbonate may be associated with increased mortality and does not reduce intraventricular hemorrhage.
Abstract:
Sixty-two high-risk acidemic premature newborn infants, given maintenance intravascular infusions of 10% glucose, were assigned to liberal or restricted sodium bicarbonate treatment groups. Those infants in the liberal group received 5 to 15 mEq bicarbonate/dl 10% glucose, depending on the degree of acidosis. Among infants given bicarbonate, correction of pH was not more rapid and mortality was not decreased. Instead, there was a small increase in the number of deaths, but the incidence of intraventricular hemorrhage was similar to that in infants not given bicarbonate.
