ICD-10: P74.2

ICD-10 code P74.2 refers to "Disturbances of sodium balance of newborn." This condition is categorized under the broader classification of disorders related to electrolyte imbalances, specifically focusing on sodium levels in neonates. Below is a detailed overview of this condition, including its clinical description, causes, symptoms, diagnosis, and management.

Clinical Description

Disturbances of sodium balance in newborns can manifest as either hyponatremia (low sodium levels) or hypernatremia (high sodium levels). Sodium is a crucial electrolyte that plays a vital role in maintaining fluid balance, nerve function, and muscle contraction. In newborns, maintaining proper sodium levels is particularly important due to their developing physiology and the rapid changes they undergo after birth.

Causes

The disturbances in sodium balance can arise from various factors, including:

• Inadequate intake: Insufficient sodium intake through breast milk or formula can lead to hyponatremia.
• Excessive loss: Conditions such as diarrhea, vomiting, or excessive sweating can result in significant sodium loss.
• Fluid overload: Administering excessive intravenous fluids, particularly those low in sodium, can lead to dilutional hyponatremia.
• Renal issues: Congenital renal anomalies or conditions affecting renal function can disrupt sodium reabsorption and excretion.
• Hormonal imbalances: Disorders affecting the adrenal glands, such as congenital adrenal hyperplasia, can impact sodium balance.

Symptoms

Symptoms of sodium imbalance in newborns can vary based on whether the condition is hyponatremia or hypernatremia:

• Hyponatremia: Symptoms may include lethargy, irritability, poor feeding, seizures, and in severe cases, coma.
• Hypernatremia: Symptoms can include excessive thirst, dry mucous membranes, irritability, and neurological signs such as seizures or altered consciousness.

Diagnosis

Diagnosis of sodium balance disturbances typically involves:

• Clinical assessment: A thorough history and physical examination to identify potential causes and symptoms.
• Laboratory tests: Serum sodium levels are measured through blood tests. Additional tests may include electrolyte panels, renal function tests, and urinalysis to assess kidney function and fluid status.

Management

Management of sodium balance disturbances in newborns focuses on correcting the underlying cause and restoring normal sodium levels:

• Hyponatremia: Treatment may involve careful administration of sodium, either orally or intravenously, depending on the severity. Fluid restriction may also be necessary to prevent further dilution.
• Hypernatremia: Management typically includes gradual rehydration with isotonic fluids to avoid rapid shifts in sodium levels, which can lead to cerebral edema.
