Injury of lung — Clinical Guidelines

Overview

Lung injury encompasses various traumatic and toxicological causes, including traumatic contusions, sepsis, and toxic exposures such as vaping-associated lung injury (EVALI). These injuries can lead to severe respiratory complications requiring intensive care management.

Diagnosis

Clinical Presentation: Symptoms include respiratory distress, hypoxemia, and signs of sepsis or toxic exposure 1 7 10.

Imaging: Chest X-rays and CT scans to identify contusions, infiltrates, or signs of acute respiratory distress syndrome (ARDS) 1 7.

Laboratory Tests: Blood cultures, inflammatory markers (CRP, WBC), and specific biomarkers for EVALI (e.g., vitamin E acetate detection) 1 10 11.

Histopathology: In cases of electrocution, histopathological examination may reveal lung injury not apparent grossly 7.

Management

Supportive Care: Mechanical ventilation, oxygen therapy, and hemodynamic stabilization 1 10.

Antibiotics: For suspected or confirmed sepsis 1.

Corticosteroids: High-dose methylprednisolone (30 mg/kg i.v. x 3 at 8-hour intervals) for acute traumatic lung injury 20.

Toxic Exposure Management: Decontamination procedures post-stabilization, use of antidotes where available 6.

Specific EVALI Treatment: Supportive care with extracorporeal membrane oxygenation (ECMO) in severe cases 11.

Special Populations

Pediatrics: Unintentional exposures more common; lower toxicity but increased risk with age 3.

Elderly: Higher susceptibility to complications due to comorbidities; tailored supportive care required 21.

Comorbidities: Patients with pre-existing respiratory conditions may have worse outcomes; individualized management plans needed 20.

Key Recommendations

Early High-Dose Corticosteroid Administration for acute traumatic lung injury to reduce inflammation and improve outcomes (Evidence: Strong 20).

Supportive Mechanical Ventilation for patients with severe respiratory failure due to lung injury (Evidence: Moderate 1 10).

Toxic Exposure Decontamination following initial stabilization to prevent further harm (Evidence: Moderate 6).

Monitor and Manage Specific Biomarkers in suspected EVALI cases for targeted intervention (Evidence: Moderate 10 11).

Tailored Care Plans for elderly and pediatric patients considering their unique vulnerabilities (Evidence: Expert opinion 3 21).
