Clinical Scorecard: Elevated serum total carbon dioxide levels at admission are linked to increased risk of early seizure recurrence in pediatric patients with benign convulsions associated with mild gastroenteritis

At a Glance

Key Highlights

• 26.7% of children experienced seizure recurrence within 48 hours.
• Median TCO2 was significantly higher in the recurrence group (17.4 vs. 15.1 mmol/L).
• Higher TCO2 levels were independently associated with recurrence (odds ratio 1.235).
• A TCO2 cutoff of 16.25 mmol/L showed 78.3% sensitivity and 61.9% specificity.
• Strong correlation between venous TCO2 and arterial bicarbonate (r = 0.966).

Guideline-Based Recommendations

Diagnosis

• Diagnosis of CwG based on clinical criteria and exclusion of other causes.

Management

• Consider monitoring intensity based on admission TCO2 levels.

Monitoring & Follow-up

• Observe children with higher TCO2 levels closely for seizure recurrence.

Risks

• Younger age and higher TCO2 levels are associated with increased risk of recurrence.

Patient & Prescribing Data

Children aged 6 months to 6 years with benign convulsions and mild gastroenteritis.

Anticonvulsant use may be considered based on clinical assessment and TCO2 levels.

Clinical Best Practices

• Utilize TCO2 as a readily accessible biomarker for risk stratification.
• Conduct further validation in prospective cohorts.
