[Respiratory insufficiency in acute bronchiolitis in infancy]
Insights
Severe acute viral bronchiolitis in infants can be successfully treated with mechanical ventilation, significantly reducing mortality. This study highlights effective management strategies for respiratory failure in young children.
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.
Abstract:
Forty-one infants with acute viral bronchiolitis were hospitalized in our paediatric intensive care unit during the seven year period from 1980 to 1987. In 14 out of 27 evaluated patients, Respiratory Syncitial Virus (RSV) was detected in the nasal secretions. Twenty-three children required only supportive care and monitoring. Eighteen infants had to be ventilated because of respiratory failure. The major indication for mechanical ventilation was an arterial or capillary pCO2 of more than 64 mmHg; other criteria were repeated apnoea, respiratory acidosis, and clinical deterioration. In all cases the type of the mechanical ventilation was an intermittent mandatory ventilation (IMV) with flow and time cycled respirators; muscle relaxation was not required in any case. The average duration of mechanical ventilation was 40 hours. All the children recovered uneventfully. These data suggest that even the most severe cases of acute bronchiolotis can be treated successfully, and that the mortality rate of this disease entity can be reduced to zero.
