Insights
Apnea occurs in over 5% of infants under 12 months hospitalized for acute bronchiolitis. Young age and prematurity are key risk factors for infant apnea, regardless of viral cause.
Area of Science:
- Pediatrics
- Infectious Diseases
- Respiratory Medicine
Background:
- Acute bronchiolitis is a common respiratory infection in infants.
- Apnea is a recognized complication of acute bronchiolitis, particularly in younger infants.
- Identifying risk factors for apnea is crucial for timely intervention.
Purpose of the Study:
- To determine the frequency of apnea in infants hospitalized with acute bronchiolitis.
- To identify common viral pathogens associated with apnea in this population.
- To investigate risk factors for apnea, including age, prematurity, and specific viral infections.
Main Methods:
- Retrospective chart review of infants <12 months admitted with acute bronchiolitis.
- Analysis of viral detection in nasopharyngeal samples.
- Statistical analysis to identify risk factors for apnea.
Main Results:
- The incidence of apnea was 5.16% among infants with acute bronchiolitis.
- Respiratory syncytial virus (RSV) was the most common virus (33.3%), followed by rhinovirus (13.7%).
- Younger age and prematurity were significant risk factors for apnea, irrespective of RSV status. Infants without RSV showed a higher rate of prematurity.
Conclusions:
- Apnea is a notable complication of acute bronchiolitis in infants.
- Prematurity and young age are critical risk factors for developing apnea.
- Understanding these risk factors can aid in managing infants with bronchiolitis.
Abstract:
The frequency of apnea in infants <12 months of age admitted with acute bronchiolitis was 5.16% (95% confidence interval: 3.94-6.72). Most commonly detected viruses in the 51 apneic infants were respiratory syncytial virus (33.3%), rhinovirus (13.7%) and viral coinfections (23.5%). Young age and prematurity were the main risk factors for apnea independent of the respiratory syncytial virus status. Non-respiratory syncytial virus infants had a higher rate of prematurity.

Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
Critical Guidelines for Assessing Ventilation:
Common Respiratory Disorders
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...
