Introduction: Sodium is the ion with the highest extracellular concentration and thus also determines the osmolality in the extracellular space. The lower the serum sodium, the more serious the dilemma.
Case Series:
Case 1: A eutrophic female was born at 37+3 weeks gestation, birth by vacuum extraction, birth weight 2570-gram, umbilical cord blood gas analysis performed in delivery showed severe hyponatremia (sodium 122 mmol/L).
Case 2: A eutrophic male was born at 40+4 weeks gestation, spontaneous labor, birth weight 3230-gram, suspicion of cerebral seizure, postpartum hyponatremia, perinatal metabolic acidosis, respiratory failure, and hypoxic ischemic encephalopathy.
Case 3: A eutrophic male was born at 38+4 weeks gestation, spontaneous birth, birth weight 2895-gram, postpartum severe hyponatremia, suspicion of cerebral seizure, cyanosis attacks.
Case 4: A preterm female was born at 31+1 weeks gestation, birth weight 1195-gram, sodium 125 mmol/L, potassium 6.3 mmol/L with respiratory disorder.
Conclusion: We recommend a quick diagnosis and stop the factors that cause hyponatremia. Laboratory tests, history, and physical examination could reduce hyponatremia to ensure adequate treatment.
Keywords: Fetal hyponatremia, Laboratory tests include serum sodium, Maternal hyponatremia, Plasma osmolality, Urine sodium and osmolality
