[Respiratory insufficiency in acute bronchiolitis in infancy]

Area of Science:

• Pediatrics
• Intensive Care Medicine
• Virology

Context:

• Acute viral bronchiolitis is a common respiratory illness in infants.
• Hospitalization in a pediatric intensive care unit (PICU) is often required for severe cases.
• Respiratory Syncitial Virus (RSV) is a primary causative agent.

Purpose:

• To evaluate the outcomes of infants hospitalized with severe acute viral bronchiolitis.
• To assess the role and efficacy of mechanical ventilation in managing respiratory failure.
• To determine the mortality rate associated with severe bronchiolitis in a PICU setting.

Summary:

• Forty-one infants with acute viral bronchiolitis were admitted to the PICU between 1980 and 1987.
• Respiratory Syncitial Virus (RSV) was detected in 14 of 27 evaluated patients.
• Eighteen infants required mechanical ventilation due to respiratory failure, primarily indicated by elevated pCO2 (>64 mmHg), apnea, or acidosis.
• Intermittent mandatory ventilation (IMV) was used, with an average duration of 40 hours; muscle relaxation was not needed.
• All infants recovered without complications.

Impact:

• Successful treatment of severe acute viral bronchiolitis is achievable.
• Mechanical ventilation, specifically IMV, is an effective strategy for managing respiratory failure in these infants.
• The study demonstrates a zero mortality rate for severe acute bronchiolitis in the studied cohort.
• These findings support aggressive respiratory support to reduce mortality from this disease.
