Hello all,
We started placing pediatric PICC lines a year ago and are having problems getting an accurated measurement for the smaller peds (<40 kg). We are coming up 5 to 7 cms long. Is there a different way to measure the smaller peds than there is for the larger pediatrics and adults?
Thank you,
Pam
I have been placing pediatric PICCs for about 8 years now and my measurements tend to be case by case but in general I usually add 0cm from the right and 2cm from the left. This is just what has worked for me from my experience. Best of luck!

Thank you!
We have actually developed an estimator formula based on height (or length) in cms which we have used for several years. It has been validated by our pediatric practice but not yet published. As long as the height measurement is accurate, it will definitely get you in the ballpark consistently. For upper extremity PICCs from the Right basilic vein: take the height in cm x 13 then divide the result by 50. For example, if the height is 90 cm, the estimator is 23. This is from the right AC, and we measure by feeling the distal end of the humerus at the AC as the reference point, because this can be felt through the drapes. Whatever distance my access point is above that mark, I will deduct that from my measurement. So again, if 23 is the estimator, but I am 7 cm above that AC landmark, I will deduct that and final amount would be 16 cm. If the cephalic vein is used, it will be slightly longer, and if the left arm is used it will also be slightly longer. If the vein is unusually deep (for a peds patient), like 2-3 cm, I will add that as well. We use this for preemies all the way to adolescents and it is very reliable.
Thank you! We may give this a try as well.
