The most common Gram-positive bacteria were Staphylococcus aureus (25.5%), and the most common Gram-negative bacteria were Escherichia coli (33.3%). The drug resistance analysis results showed that, except for 精品文档---下载后可任意编辑cephalosporin combination, most of the commonly used antibiotics showed a certain degree of drug resistance, with some exhibiting multidrug resistance.Conclusion: The main distribution of pathogens in the emergency ICU of our hospital is Gram-negative bacteria, which exhibit varying degrees of drug resistance. Rational use of antibiotics and formulations of appropriate antibiotics and treatment course based on drug sensitivity test results are recommended to reduce the occurrence and spread of bacterial resistance to antibiotics.【Keywords】Emergency ICU; Pathogen; Drug Resistance; Antibiotic use.
