Abstract
Objective: To analyze the microbiological profile of peripherally inserted central catheters (PICC) and short peripheral intravenous catheters (PIVC). Method: A cross-sectional, quantitative study was conducted from April 2023 to October 2024. Removal of PIVC was indicated by signs suggestive of infection, phlebitis, or other clinical changes. Removal of PICC occurred per medical order or upon completion of therapy. Sociodemographic and clinical data were collected at the time of device removal. Results: A total of 30 PIVCs were analyzed, 12 of which (40%) showed microbial growth. The most prevalent organisms were Staphylococcus epidermidis and Staphylococcus haemolyticus. Both were resistant to oxacillin, gentamicin, levofloxacin, clindamycin, erythromycin, and rifampin. Of the 18 PICC tips, 5.55% yielded Staphylococcus capitis. A positive blood culture for Pseudomonas putida occurred in 5.55% of cases without corresponding growth on the catheter tip. Conclusion: Gram-positive bacteria predominated, with a higher occurrence in PIVC. Findings suggest that the patient’s diagnosis influences the identified microbiological profile.
