Background & Aim: Peripherally intravenous catheters (PIVs) are an important part of therapy for hospitalized children. Although such catheters provide necessary vascular access, their use puts patients at risk for local and systemic infectious complications with serious morbidity. Migration of skin organisms at the insertion site into the coetaneous catheter tract with colonization of the catheter tip is the most common rout of infection for peripherally inserted catheters in adults but in children this is controversial. The objective of this study is to find any relationship between colonization and catheter-related consequences. Methods & Materials: In a descriptive cross-sectional study, 108 catheters of children and neonates hospitalized in NICU and infectious ward of Markaz Tebby Kodakan were cultured at a 2-month period. For all cases, a questionnaire of demographic characteristics and information about catheterization including location, dwell time, drugs and total parental nutrition was filled. The condition of catheterization for all cases was the same. Presence of only one colony was considered as positive colonization. Finally the data were analyzed by SPSS software. Results: Excluding one case because of positive blood culture, from 107 catheters, 36 were colonized (33.6% of cases). Coagulate negative staphylococcus was the most common pathogen seen in 50% of total positive cases. Although there was a clinically significance between the dwell time of catheter and colonization but there was not any statistical significant association between colonization and any other variables including sex, age, hospitalization time, ward, location of catheter, dwell time, infusion of parental nutrition, and the administered drug. Conclusion: This study is consistent with guidelines of CDC about avoiding unnecessarily routine replacement of catheters in neonates and children. As the risk of infection did not increase in association with dwell time of peripheral venous catheters, it seems it is better to leave catheters in place until there is a sign of local infection or infiltration.
