Risk Factors and Distribution of Pathogens for Pulmonary Infection in Patients with Severe Acute Pancreatitis

Quanshui Peng, Peng Chen, Di He

Abstract: Objective: To investigate risk factors and distribution of pathogens for pulmonary infection in patients with severe acute pancreatitis. Methods: The clinical data of 285 patients with severe acute pancreatitis were retrospectively analyzed. Sputum specimens of patients with lung infections were studied. Univariate analysis and logistic regression were performed to screening the factors correlating to lung infections. Results: Gram-negative bacilli were the principal microorganisms isolated from those lung infections, and these bacterial pathogens demonstrated a marked pattern of antibiotic resistance. It was identified that age (OR 1.05, 95% CI 1.01-1.09, p=0.01), Ranson scores (OR 3.01 , 95% CI 1.13-8.03, p = 0.03) and surgical treatment (OR4.27, 95% CI 1.03-17.65, p = 0.04)were independent risk factors of lung infections in patients with severe acute pancreatitis. Conclusion: Analysis of pathogen spectrum and drug sensitivity will contribute to choosing antibiotics empirically. And preventive measures aimed at risk factors could help reduce the incidence of lung infections in patients with severe acute pancreatitis.
