Objective: Healthcare associated infections are an important health problem that can occur as a complication of modern medical practices and pose a threat to public health. We report an outbreak of pseudo- heparin injectors infected with S. maltophilia. Material and Methods: This retrospective study was conducted at a PICU between November 2021 and February 2022. Results: Two hundred and twenty-five patients were followed up in our pediatric intensive care unit during the study period, and S. maltophilia growth was detected in the control catheter cultures taken immediately after catheterization in 12 (5.33%) of them. Of these patients, 121 jugular and three femoral catheters were inserted. It was determined that the catheter cultures were taken with the same brand (E brand) heparin injectors. Mean age of the 12 patients included in the study was 70.58 ± 81.02 months, seven (58.3%) were male. Of the patients, six were hospitalized due to pneumonia, three postoperatively, two due to non-vehicle traffic accident (NVTA) and one due to chronic renal failure. Six patients had comorbid conditions, of whom five had syndromic conditions and one had chronic renal failure. Mean hospital stay of the patients in the intensive care unit was 27.17 ± 34.41 days. Eleven (91.67%) of the patients were discharged with good recovery. One patient (NVTA) died due to non-sepsis causes. A statistically significant decrease was found in the white blood cell values from the seventh day after the catheterization of the patients (p= 0.014). In addition, mean platelet values did not increase after insertion of the catheter, on the contrary, they showed a constant tendency to decrease (p= 0.272). Procalcitonin values did not increase in the period after the insertion of the catheter, on the contrary, they showed a continuous decrease (p= 0.309). CRP values were shown to decrease statistically significantly in the days after the catheter was inserted (p= 0.027). Conclusion: Considering antibiotic resistance and mortality, it is vital to pay attention to sterilization rules and to control the effectiveness of sterilization in terms of gram-negative bacteria that are resistant even to disinfectants.
