What laboratory findings are expected for an infant who experienced asphyxia during delivery?

When an infant experiences asphyxia during delivery, the expected laboratory findings typically include acidosis, hypobicarbonatemia, and hypoglycemia. Asphyxia leads to decreased oxygen supply, which impacts cellular metabolism and promotes the production of lactic acid, resulting in metabolic acidosis. This condition is characterized by a decrease in blood pH and bicarbonate levels, contributing to the acidosis.

Hypobicarbonatemia occurs as a secondary response to the increase in acidity, reflecting the body’s attempt to buffer the excess hydrogen ions. Additionally, hypoglycemia can arise due to stress from the asphyxia which can impair hepatic glucose production and release, leading to lower-than-normal blood sugar levels. This combination of metabolic changes is critical for clinicians to recognize in the context of neonatal care, as it guides treatment and intervention strategies for affected infants.
