Body Surface Area

[JACK]

Do you calculate BSA for your neonates? Which neonates are indicated for calculation of BSA? What formula do you use?

Must admit that we use weight as the correcting factor (/kg) when it comes to medications at least.
A few years we had an extremely preterm infant with Hemophagocytic lymphohistiocytosis (HLH) who were treated with cytostatic drugs. If I recall this correctly, the pediatric oncologists calculated doses by body surface area.
This is a bit off-topic, but this case was published:

Thanks for the link
Do you remember which formula they used in that case?

Did they use the BSA as derived from weight only as mentioned in this article http://www.nature.com/bjc/journal/v85/n1/pdf/6691859a.pdf ? Or did they take both weight and length into calculation?

I am sorry but I do not know.
However, this infant was critically ill, and I would guess that we did not have a valid recording of the body length. So, my guess is that weight was used to derive BSA.
