Just a small matter of semantics as the term "pediatric intensivist" has come up a couple times--
NICU= neonatology== newly born who are critically ill==attendings are neonatologists.
PICU= pediatric critical care (all critically ill children who are not newly born ages 0-18)== attendings are pediatric intensivists
I've maintained that neonatal ICU rotations for the anesthesia resident are not necessary and in fact are superfluous-- it is a completely different story for the peds anesthesia fellow who needs to learn the nitty gritty details of neonatal fluids, peri-op care, etc.
IMHO the pediatric intensive care unit (PICU) rotation is much more valuable to the anesthesia resident who will more than likely be taking care of children during some point in their career, and need exposure to a wide range of ages and physiology. This of course is predicated on what doze said i.e. learning from pediatric intensivists, peds residents-- although in our PICU the anesthesia residents are in the same role as the pediatric residents, which means there is scut but there is huge amounts of learning as well.
