Which of these choices is not considered a prevention method for acute lung injury?

• A. Hemofiltration
• B. Serine protease inhibitors
• C. Corticosteroids
• D. Heparin-bonded circuits

Answer: (C)

Corticosteroids are primarily used for their anti-inflammatory effects in various conditions, including acute lung injury (ALI). However, they are not typically classified as a primary prevention method for ALI. Instead, corticosteroids are often employed in the treatment phase to manage symptoms and reduce inflammation once ALI has developed. In contrast, the other choices have established roles in preventive strategies. For instance, hemofiltration can help manage fluid overload and filter out inflammatory mediators that could contribute to lung injury. Serine protease inhibitors are thought to modulate inflammatory responses and tissue breakdown, potentially protecting lung tissue from injury. Heparin-bonded circuits minimize coagulation and inflammation during procedures like cardiopulmonary bypass, thereby reducing the risk of lung injury. Therefore, while corticosteroids play a critical role in the management of established acute lung injury, their role as a preventive measure is less defined compared to the other options listed. This distinction makes corticosteroids the choice that does not fit as a prevention method for acute lung injury.
