Postpartum severe hyponatremia in preterm birth and mature newborns: Dangers for mother and child?

Abstract

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

Association of maternal mineral status with the risk of preterm birth: a retrospective cohort study

“…In addition, enhanced uterine smooth muscle tone and uterine contractility may lead to the occurrence of preterm birth (21,22). Sodium(Na) retention during pregnancy can lead to alterations in maternal blood pressure and weight, thereby influencing fetal growth (23). Reduced potassium(K) levels may induce premature contraction of the uterus, leading to preterm birth (24).…”
