Epidemiology and causes of acute respiratory distress in children: a retrospective study at a tertiary hospital in Tehran.

BACKGROUND AND AIM: Respiratory distress is one of the most common underlying causes of emergency department visits in children, with a high morbidity and mortality rate which could raise a lot of concerns, acquiring early recognition of the underlying cause and appropriate treatment. The current study aimed to determine the prevalence and distribution of underlying causes of respiratory distress.

METHODS

In this retrospective cohort study, demographic and clinical information of 154 patients older than 1 month who were referred to a tertiary hospital from October 2018 to April 2019 were gathered from Hospital Information System and analyzed with SPSS Statistics 23.0 version.

RESULTS

154 participants were recruited with a mean age of 33.02 ± 37.21 months, and 66% were male. The most common clinical symptom among these children was tachypnea (90.6%). Asthma (35.1%), pneumonia (31.8%), sepsis (8.4%), bronchiolitis and croup (7.8%), and foreign body (7.1%) were the most common causes of respiratory distress.

CONCLUSION

Respiratory distress can be manifested with a variety of signs and symptoms and different underlying causes which may defer in different genders, ages, and regions. Among patients referred to a tertiary center in Tehran, tachypnea was the most common clinical symptom, and asthma was the most frequent cause of respiratory distress. Knowing the underlying causes of this emergent clinical status in pediatrics can help us in developing appropriate treatment approach.
