Pulmonary infections
Pulmonary infections are a leading cause of morbidity and mortality in critically ill patients, often requiring prompt diagnosis and aggressive management. These infections range from community-acquired pneumonia (CAP) to hospital-acquired pneumonia (HAP), ventilator-associated pneumonia (VAP), aspiration pneumonia, and viral pneumonitis. Each type presents unique challenges in identification, antimicrobial therapy, and supportive care.
The effective management of pulmonary infections in the ICU relies on early recognition, appropriate risk stratification, and evidence-based treatment protocols. Empiric antibiotic therapy must be carefully selected and adjusted based on microbiological findings and patient response. De-escalation strategies and infection control measures play a critical role in preventing resistance and improving outcomes. In addition to bacterial infections, viral and fungal pneumonias require targeted approaches, including antiviral or antifungal therapy and optimized ventilatory support.
Preventing pulmonary infections is equally important in critical care settings, with strategies such as strict infection control, aspiration risk reduction, and immunization programs proving effective in reducing incidence. By adhering to current guidelines and evidence-based protocols, ICU professionals can improve survival rates and reduce the burden of pulmonary infections in critically ill patients.
