Influenza A triggered status asthmaticus requiring emergency ECMO

Area of Science:

• Medicine
• Infectious Diseases
• Pulmonology

Background:

• Influenza A virus infections typically cause respiratory illness.
• Severe cases can lead to acute respiratory failure.
• Status asthmaticus is a severe form of asthma exacerbation.

Observation:

• A case of acute respiratory failure secondary to severe pneumonia caused by influenza A virus is presented.
• The condition rapidly progressed to status asthmaticus refractory to standard medical and ventilatory support.
• Emergent extracorporeal membrane oxygenation (ECMO) was required for management.

Findings:

• Influenza A virus infection can manifest as severe pneumonia complicated by refractory status asthmaticus.
• Medical and conventional mechanical ventilation may be insufficient for such severe cases.
• ECMO can be a life-saving intervention in refractory cases.

Implications:

• This case highlights a rare but critical presentation of influenza A virus infection.
• Prompt consideration of ECMO is vital when patients with severe pneumonia and status asthmaticus do not respond to initial treatments.
• ECMO can mitigate lung injury associated with inadequate ventilation in severe respiratory failure.
