Background: Tal et al. severity score (TSS) and Modified Wood’s Clinical Asthma Score (M-WCAS) are used to evaluate the severity of the disease in children with bronchiolitis. It has recently been suggested that there is a relationship between bronchiolitis severity and hyponatremia.
Aims and Objective: This study aimed to evaluate the relationship between both of scores and hyponatremia in children with bronchiolitis.
Materials and Methods: This prospective observational study included 172 patients (age range: 1-24 months) admitted to the hospital with bronchiolitis diagnosis. Demographic and clinical features of patients were recorded, and the TSS and the M-WCAS were calculated. These values and their components were compared with serum sodium (Na) results obtained at hospital admission.
Results: Of the 172 patients, 114 (66.3%) were male, and the mean age was 5.5 ± 4.6 months. The mean TSS and M-WCAS of the patients were 6.73±1.9, and 3.34±1.4, respectively. Hyponatremia (Na<135mEq/L) was detected in 30 (17.4%) patients. When the TSS and M-WCAS of patients with and without hyponatremia were compared, there was no statistically significant difference (p = 0.517; p = 0.662, respectively); however, there was a significant relationship between hyponatremia and low oxygen saturation levels (p= 0.026).
Conclusion: No relationship was found between hyponatremia and TSS & M-WCAS. However, the relationship between hyponatremia and hipoxia suggests that hyponatremia is likely to increase with the severity of the disease.
