Weight as the best standard for glomerular filtration in the newborn

Abstract

The relation between surface area and body weight changes dramatically in infancy. In 31 healthy infants of 27 to 40 weeks' gestation, variations in glomerular filtration rate were reduced more than twofold by choosing glomerular filtration rate/kg, body weight rather than glomerular filtration rate/m . The former provides the most useful and practical index of renal function in the neonate.
