Sodium bicarbonate infusion during resuscitation of infants at birth.

For many years, intravenous sodium bicarbonate has been used to reverse acidosis during newborn resuscitation. However, controversy surrounds its use. Most of the evidence has been derived from studies in animals, adult humans, or in uncontrolled, descriptive experiments. Despite the lack of evidence from the human neonatal population and concerns about its safety, some international resuscitation guidelines still recommend the use of sodium bicarbonate in resuscitation of the newborn.
