Background and objectives: inanimate surfaces and equipment in the hospital environment are considered reservoirs of resistant and pathogenic microorganisms. In Pediatric Intensive Care Units, the risk of infection is also related to the severity of pathologies associated with the immaturity of the immune system of this population. This study aimed to investigate microbiological environmental contamination in a Pediatric Intensive Care Unit. Method: this is an exploratory cross-sectional study, carried out in a Pediatric Intensive Care Unit of a highly complex university hospital, located in southern Brazil. To assess environmental contamination, sterile swabs were rubbed on surfaces corresponding to the patient unit and in the common area. Results: twenty-eight surfaces were analyzed, 12 of which were located in units occupied by patients at the time of collection and 16 surfaces in the common use area. In the total number of surfaces analyzed by microbiological cultures, the patient unit showed 66.67% contamination by microorganisms, while surfaces in the common area showed 56.25%. Regarding the microbiological profile, all isolated microorganisms were Gram-positive and showed resistance, namely Staphylococcus aureus and coagulase-negative Staphylococcus. Conclusion: there was evidence of a high frequency of contamination on inanimate surfaces and equipment near and far from patients, essentially by pathogenic and multi-resistant microorganisms to antimicrobials.
