Abstract
BACKGROUND: Hyponatremia is a prevalent and serious electrolyte imbalance in pediatric pneumonia and is linked to increased disease severity and adverse outcomes. Oral rehydration solution (ORS) is an available, inexpensive, safe, and ready-to-use oral solution that can supplement sodium in such cases. AIM: To assess the impact of prophylactic sodium supplementation via ORS on clinical and hospital outcomes in infants and children admitted with pneumonia. METHODS: A randomized, interventional controlled trial was conducted on 140 infants and children admitted with pneumonia (70 per group). The primary outcome was hospital length of stay, with secondary outcomes including serum sodium and potassium levels, clinical respiratory scores, modified shock index, and nutritional/inflammatory markers. The hospital length of stay and both the laboratory and clinical parameters of the interventional and control groups were compared. RESULTS: The hospital stay was longer in the control group than in the intervention group (P value = 0.001; effect size = 0.59). Clinical respiratory scores on day 4 were significantly lower in the intervention group than in the control group (P value = 0.001). Sodium levels were significantly lower in the control group than in the intervention group at discharge (P value = 0.002). CONCLUSION: Prophylactic oral sodium supplementation through ORS may have a health-promoting effect on infants and children admitted with pneumonia.
