ABSTRACT
Background: Bronchiolitis, caused mostly by Respiratory syncytial virus (RSV) virus is the leading cause of lower respiratory tract infection in infants. The disease is mostly presents with cough runny nose, fever, breathing difficulties and respiratory failure This infection usually affects children up to age of 24 months, with younger infants often more severely affected and is the most prevalent cause of hospitalization in infants under the age of 12 months. The treatment is supportive; therefore, epidemiology, clinical, laboratory, and radiologic findings can help to ensure appropriate diagnosis and proper treatment.Methods:This descriptive cross-sectional observation study was conducted at Paediatrics department of Sher-E-Bangla Medical College & Hospital (SBMCH), Barishal, Bangladesh between October 2018 to March 2019To find out the clinico-epidemiological and radiological profile of Bronchiolitis. Children below 24 months of age diagnosed as bronchiolitis were studied.Results:200 children were evaluated, including 150 boys and 50 girls; Infants below 6 months accounted for the highest proportion (60%). All the bronchiolitis patients had cough or cold with respiratory distress. Other symptoms were fever (98.0%), restlessness (63.0%), poor feeding (60%) and fast breathing. On examination lower chest indrawing and rhonchi were found in all cases. Hyperinflation was the most prevalent radiological finding (60%) and more than half (55%) patients had lymphocytosis on CBC.Conclusion:Most children present with typical clinical and radiological feature of bronchiolitis which can help the clinicians to clinically identify this disease more efficiently.
