BALSALOBRE FILHO, Leonardo Lopes et al. Nosocomial sinusitis in an intensive care unit: a microbiological study. Braz. j. otorhinolaryngol. (Impr.) [online]. 2011, vol.77, n.1, pp.102-106. ISSN 1808-8694.

Nosocomial sinusitis is a common complication of patients in ICUs. Its diagnosis is important, and early treatment is required to avoid serious complications such as pneumonia, sepsis, meningitis, and intracranial abscesses. AIM: To identify the germs causing sinusitis in ICUs by nasal swabs and maxillary sinus puncture, and to correlate these results. METHODS: ICU patients with a diagnosis (CT confirmed) of maxillary sinusitis underwent nasal swab and puncture of the sinus to collect material for culture and antibiogram. RESULTS: This study evaluated 22 patients. The microbial agent isolated in the swab correlated with the agent in the puncture in 14 of 22 cases (63%). Gram-negative bacteria were the most frequent, as follows: Pseudomonas aeruginosa (29% of punctures), following by Proteus mirabillis (26%) and Acinetobacter baumanni (14%). The resistance index in the antibiogram was high to antibiotics. CONCLUSION: Maxillary sinus puncture of ICU patients with sinusitis appears to be the best method for identifying bacteria; antibiograms demonstrate resistance to therapy. The swab has little diagnostic value; the correlation was 63%. It may be used when sinus puncture is contraindicated.
