Analysis of pathogens and drug-resistance of bacterial pneumonia in emergency intensive care unit

Objective: To study and analyze pathogens and drug-resistance in patients with bacterial pneumonia in emergency intensive care unit(EICU), guiding the anti-infection strategy of bacterial pneumonia. Methods: A total of 161 sputum culture-positive bacterial pneumonia patients admitted to the EICU of the Third Affiliated Hospital of Naval Medical University from January 2018 to November 2019 were selected to analyze pathogens and drug-resistance. Results: Gram-negative bacteria(80.9%) were the main pathogenic bacteria. Multi-drug resistant organisms(MDRO) were common and had high resistance to commonly used antibiotics. Conclusion: The pathogenic bacteria of the patients in the EICU bear certain resistance to empirical anti-infective treatment strategies. Understanding the classifications of pathogenic bacteria and the characteristics of drug-resistance is beneficial to develop a more effective anti-infection strategy.
