Miller et al used nomograms to describe the weight change in a formula fed neonate in the first 3 days after delivery by cesarean section. The authors are from Penn State College of Medicine in Hershey, Kaiser Permanente Oakland and the University of California in San Francisco.
An infant may lose 0 to 10% of body weight over the first 2 to 4 days after delivery, then gradually increases in weight for the rest of the first month.
Patient selection: cesarean section
Time interval modeled: 6 to 60 hours after delivery (after 60 hours the weight may start to trend upwards)
Outcome: percent weight change from birth weight, with weight in grams
