Peripheral central catheter application, especially in extremely low birth weight premature babies, is an intensive care follow-up procedure. There are many clinical studies in areas such as catheter type, skin disinfection, catheter duration, catheter infection. In our practice, it was observed that premature baby was less uncomfortable, the number of trials decreased, and the change in body temperature was less with the application of hot skin disinfection in our practice. With a prospective randomized study, the investigators wanted to document their observational data scientifically.

Babies under 32 gestation week and 1250 g who are treated at level 3 NICU and need peripheral central catheter will be included in the study. In the preparation of peripheral central catheter application, skin cleaning is performed with povidone iodine in our clinic. The investigators used during the povidione iodine preparation phase after heating the bain-marie method with sterile conditions. The investigators predicted that the premature baby would have less discomfort with warm povidion iodine. To demonstrate this, it was planned to take both video recordings during the application and N-PASS evaluation by an experienced person who does not know the povidone iodine temperature used .In preparation of the catheter except the person who did povidone iodine skin cleansing, nobody knows the heat. The catheters were administered by a single experienced person. The study was designed to be unaware of the povidin iodine application temperature of the person applying the catheter and the N-PASS assessment.
