In the recent years although the cares during pregnancy and the premature births control have promoted, the overall
prevalence of premature births has increased. this study is as a clinical trial study that was conducted on 389
premature newborns that by convenience sampling with the weight less than 1500 gr participated in the study. It was
proceeded to put centralized venous catheter for 207 newborns by the peripheral vessel (PICC) in the upper limbers
and for 182 newborns, the catheter PICC was put in the upper limbers and after passing 15 days the catheters were
exited and 4 centimeter of catheter tip in the sterile condition was sent to the laboratory for culturing and
determining the bacterial colonization. frequency of bacterial colonization in the embedded catheters in the upper
limbs was significantly more than the embedded catheters in the lower limbs (P-value=0.04). The most responsible
micro organisms forcolonization was negative coagulase- staphylococci; also between the tip of catheter and the
embedding place there was a significant relation. According to the obtained results of study in the upper limbs group,
the catheter tip place in 20.3% of cases were non central and versus in the lower limbs group 4.5% had non central
catheter tip. based on the main purpose of study, the results showed that bacterial colonization in the embedded
cathetersin both upper and lower limbs groups has been established. and according to the conducted studies it can be
said that incidence risk of bacterial colonization in the upper limbs is more than lower limbs. Therefore it is necessary
to be more careful for choosing the appropriate vessel for catheterization of central venous; and also due to creation
of colonization regardless of the embedding place of catheterNursesshould bemore cautious in terms of
decontamination and preparation of the embedding catheter place. The results showed that the colonization in 23
case (15.9%) was created in the upper limbs and 18 case (9.9%) in the lower limbs was observed; and there was a
significant different between two groups as the bacterial Colonization in the upper limbs was seen more than lower
limbs (p=0/04)
