[Lessons learned from pandemic influenza severe cases since 2009]

Area of Science:

• Critical Care Medicine
• Infectious Diseases
• Respiratory Medicine

Context:

• The management of severe influenza (flu) in intensive care units (ICUs) has undergone significant evolution since the 2009 pandemic.
• Advancements include refined mechanical ventilation strategies, the judicious use of antiviral medications, and the early implementation of extracorporeal membrane oxygenation (ECMO) for critical cases.

Purpose:

• To outline the advancements in intensive care unit (ICU) management strategies for severe influenza.
• To highlight the importance of integrated healthcare networks and epidemiological surveillance for severe flu.
• To emphasize preventive measures against nosocomial influenza transmission.

Summary:

• Mechanical ventilation techniques have been optimized for severe flu patients.
• Antiviral therapies are increasingly utilized for influenza management.
• Early initiation of extracorporeal membrane oxygenation (ECMO) has become a critical intervention for severe respiratory failure due to influenza.
• Many nations are establishing robust epidemiological monitoring systems and specialized healthcare networks, including dedicated ECMO centers.
• Patient isolation protocols and widespread influenza vaccination are crucial for preventing hospital-acquired (nosocomial) influenza outbreaks.

Impact:

• Improved patient outcomes and survival rates for severe influenza cases requiring intensive care.
• Enhanced preparedness and response capabilities for future influenza pandemics through integrated surveillance and ECMO networks.
• Reduced incidence of hospital-acquired influenza infections, protecting vulnerable patient populations.
