Hypothesis
The study aims to report the irreversible severe neurological symptoms following the hyponatremic hypertensive syndrome (HHS) in an infant after umbilical arterial catheterization.
Conclusion
Hyponatremic hypertensive syndrome should be considered in neonates with hyponatremia and hypertension, especially after umbilical arterial catheterization, as diagnostic delays can lead to severe neurological damage.
Supporting Evidence
- The infant presented with extreme hyponatremia (plasma sodium of 101 mmol/L) and hypertension.
- Neurological imaging showed extensive white matter abnormalities and sinus thrombosis.
- Follow-up MRI indicated worsening white matter abnormalities and neurological issues.
Takeaway
This study talks about a baby who got very sick because of low sodium levels and high blood pressure after a medical procedure, which caused serious brain problems.
Methodology
Case report with review of the literature.
Limitations
Lack of detailed clinical and laboratory information before the patient presented with severe hyponatremia and no data on plasma ADH, renin, and aldosterone.
Participant Demographics
A three-week-old preterm boy born at 31 weeks and 4 days gestational age.
