Management of Sepsis Patients Due to Community-Acquired Pneumonia in the Intensive Care Unit
Abstract
Introduction: Sepsis, a life-threatening response to infection, remains a critical global health issue, often triggered by community-acquired pneumonia (CAP) in vulnerable populations such as the elderly. This condition frequently requires intensive care unit (ICU) admission, necessitating adherence to evidence-based guidelines like the 2021 Surviving Sepsis Campaign (SSC) and Infectious Diseases Society of America (IDSA) recommendations. This case report highlights the application of these protocols in managing a complex sepsis case, emphasizing the role of early intervention and multidisciplinary care in improving outcomes.
Case Description: A 67-year-old male, Mr. U, presented with a 3-day history of dyspnea and 1-day history of altered consciousness. Initial assessment revealed respiratory distress (respiratory rate 32/min, oxygen saturation 88% on room air, Glasgow Coma Scale 10), with chest radiography confirming CAP. Laboratory results showed a lactate level of 4.2 mmol/L and leukocytosis (18,000/mm³), indicating sepsis. In the ICU, the patient received oxygen therapy, followed by intubation due to worsening respiratory failure. Blood cultures were obtained, and empirical antibiotics (piperacillin-tazobactam and levofloxacin) were initiated within 1 hour per SSC guidelines. Fluid resuscitation (30 mL/kg crystalloids) and norepinephrine were administered for persistent hypotension. Bronchoscopy revealed purulent secretions, aiding diagnosis and management. After 5 days…
