Objective: Primary aim of this study is to identify the predictors of hypoxia in children with bronchiolitis. The secondary aim is to find the average duration of oxygen requirement and length of hospital stay in children with hypoxia.
Methodology: A total of 65 children between the age group of 1month to 2 years with bronchiolitis were included in the study. Data were collected retrospectively from case records and prospective cases were consecutively enrolled. Oxygen saturation was monitored in all children who were admitted. A SpO2 <92% was considered hypoxia. The association between presenting clinical features and subsequent development of hypoxia was assessed using Pearson Chi Square test.
Results: The presenting features of bronchiolitis in our study were cough, fever, tachypnea, increased work of breathing and wheeze. Cough was the most common symptom and fever was the least common symptom. 59.3% of children with cough were found to develop hypoxia. Of the 23 children who had fever, 52.1% of them developed hypoxia. Among 51 children with tachypnea 68.6% had hypoxia (P=0.001).  Among 57 children who had increased work of breathing, 68% children developed hypoxia (P=0.000). 71.8% of children who had wheeze were found to develop hypoxia (P=0.05).
Conclusion: Our study shows that in children with bronchiolitis presence of tachypnea, increased work of breathing and wheeze had increased risk of developing hypoxia. Identifying these predictors of hypoxia could help to serve as a guide in deciding the need for hospitalisation in children with bronchiolitis.
