From the Research
Welding-related pneumonitis should be treated with corticosteroids, as evidenced by the most recent and highest quality study 1, which reported significant improvement in symptoms and radiologic findings after corticosteroid treatment. The primary treatment involves removing the person from exposure and providing supportive care while symptoms resolve, typically within 24-48 hours. For symptom relief, over-the-counter medications like acetaminophen (500-1000mg every 6 hours) or ibuprofen (400-600mg every 6-8 hours) can help manage fever and discomfort. Hydration is essential, with patients advised to drink 2-3 liters of water daily during recovery. In severe cases with significant respiratory distress, supplemental oxygen or bronchodilators may be necessary under medical supervision. Prevention is crucial and includes using proper ventilation systems, wearing appropriate respirators (N95 or powered air-purifying respirators), maintaining adequate workspace airflow, and taking regular breaks from welding areas. The condition occurs because metal oxides, particularly zinc oxide from galvanized steel, trigger an inflammatory response in the lungs when inhaled, leading to flu-like symptoms including fever, chills, muscle aches, headache, and respiratory symptoms that typically begin 4-12 hours after exposure. Some key points to consider in the diagnosis and treatment of welding-related pneumonitis include:
- The importance of early recognition and removal from exposure to prevent further lung damage 2, 3, 4, 5
- The use of corticosteroids in severe cases, as supported by the most recent study 1
- The need for proper ventilation and personal protective equipment to prevent exposure 2, 3, 4, 5, 1
- The potential for long-term lung damage if exposure is repeated or prolonged 5
