Abstract

Objectives: To evaluate the characteristics and factors affecting severity of acute bronchiolitis at pediatric. Subject and method: a prospective descriptive study, 441 patients under 2 years of age, diagnosed with acute bronchiolitis, were treated at the Pediatric Department - Bach Mai hospital. Results: Mean age was 8.82 ± 4.93 months. Distribution of severity according to MCBS accounted for 21.1% in the study. The group of children living with smokers had a severe rate of 38.4% higher than the group without a smoker with a severe rate of 13.9% with an OR of 2,697 (1.90 – 3,827). The preterm infants group in the study had a MCBS severity rate of 50% higher than the full term group of 19.71% (p < 0.05). The group of infants ≤ 2500g with MCBS severity was 33.3% higher than the group of infants > 2500g with the rate of 14.07%. The proportion of patients with severe RSV infection was 23.0% higher than that of the group with negative RSV of 20.3% (p>0.05). With index OR=1.13 (0.769 – 1.668). Conclusion: Acute bronchiolitis requiring hospitalization is common in the age group of 3-13 months. Some of the risk factors that increase the severity are living with smokers, having a birth weight less than 2500g and being infected with RSV.
