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.

Assessment of Ventilation
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.

Common Respiratory Disorders01:31

Common Respiratory Disorders

Respiratory disorders, a prevalent health concern globally, are generally divided into two primary categories: upper and lower respiratory tract disorders. The categorization is based on the area of the respiratory system they affect.
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,...

Microbiota of the Respiratory Tract01:29

Microbiota of the Respiratory Tract

The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more...

Respiratory Volumes and Capacities I

Assessing the respiratory rate and rhythm for a complete minute is crucial for evaluating the breathing pattern. Even a minor increase in the patient's average respiratory rate, by as little as three to five breaths per minute, is an early and vital indicator of respiratory distress. Patients with a respiratory rate exceeding twenty-four breaths per minute require close monitoring to determine the physiological alterations. This careful observation is essential for prompt recognition and...

Acute Respiratory Failure-V

The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.
Ensure that patients are monitored continuously for their response to therapy, including changes in...

Acute Respiratory Failure-II

Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
