Abstract

Objectives: Describe the etiological characteristics of bacteria and antibiotic susceptibility status in patients newly admitted to the intensive care unit. Subjects and methods: A cross-sectional descriptive study on 174 newly infected patients admitted to the Intensive Care Unit with positive culture results in the first 48 hours from August 2021 to July 2022. Results: In 174 infected patients admitted to the ICU with positive cultures, the most common bacteria were Gram-negative bacteria with the rate of K.pneumonia (34.5%), A.baumannii (29.9), P.aeruginosa (12.1%), E.coli (12.1%), S.aureus (10.9%). In which, antibiotic susceptibility of A.baumannii and K.pneumonia is tending to decrease, especially with Colistin with corresponding minimum inhibitory concentrations MIC50=0.19 µg/mL, MIC90=0.75 µg/mL and MIC50=0.38 µg/mL, MIC90=6 µg/mL. Gram-positive bacteria, mainly methicillin-resistant S.aureus (MRSA) are still sensitive to vancomycin (MIC50=1µg/mL, MIC90= 1 µg/mL). E. coli strains are still sensitive to carbapenem and amikacin. Conclusion: Patients who had an infection at the time of admission to the ICU had a severe condition. Most of the patients transferred from other places were infected with gram-negative bacteria. Antibiotic susceptibility is decreasing, especially A.baumanni and K.pneumonia.
