An egregious example of less than adequate proof-reading appears in both the title and the substance of the article by Powers and Swyer. It seems that "umbilical arterial catheterization" in the title is not really what is meant. The abstract of the article begins with the umbilical artery and proceeds to the iliac artery to end again with the umbilical artery.
I am still not sure what was studied and reported on. Was the catheter in an umbilical artery, or in an iliac artery?
