Introduction:

Infection is one of the complications that frequently affects critically ill patients.

Objective:

To determine the presence of opportunistic microorganisms in patients admitted to the Intensive Care Unit (ICU) from January to June 2021 at the Asunción Adventist Sanatorium.

Materials and methods:

Descriptive, cross-sectional study, in the period January to June 2021. The data were analyzed by EPIINFO, using descriptive statistics. Demographic variables, comorbidities, presence of COVID-19, performed procedure (intubation, mechanical ventilation, tracheostomy), length of stay in the ICU, isolated germs, administered treatment, and most frequently used antibiotics were collected from all the patients evaluated. The variable "length of stay in the ICU" corresponds to the total hospital stay of the patients in that unit.

Results:

90 patients were included in the study period. 72 were male, which corresponded to 80%. The average age was 55 ± 5.6 years. Their average hospital stay was 11 days (1-62). The most frequent comorbidities were hypertension, obesity and diabetes mellitus II. The prevalent identified microorganisms were Escherichia coli (n=9), Acinetobacter baumannii (n=9), Enterobacter cloacae (n=3); Pseudomonas aeruginosa (n=5), Staphylococcus aureus (n=1), Candida spp. (n=13), Klebsiella pneumoniae (n=7), Acinobacter sp (n=18). Overall mortality was 63.3% (57 patients).

Conclusion:

Acinobacter sp. was the most frequently isolated microorganism. Antimicrobial resistance levels were high, with all isolated germs being resistant to ciprofloxacin.
