It is dependent on the vein accessment, the site used, and the age of the patient. We have used a 2.6 dual for neonates not in NICU. We do use 2 fr catherers for infants.
Toddlers we often use 3 fr without difficulty. Again, it dependent on the assessment of the vein.
With the initial evaluation of vein size and accessibility of the vein, we also evaulaute the need for sedation. Most often, the toddlers are the most dificult to insert PICCs without sedation.
We use the Hospira Plum pump and Med-Fusion 3500 syringe pumps.
