Model of Morgenstern et al for Predicting Total Body Water (TBW) in a Pediatric Patient Undergoing Peritoneal Dialysis

Description

Morgenstern reported equations for estimating total body water for a pediatric patient undergoing peritoneal dialysis. The authors are from Phoenix Children's Hospital, University of Heidelberg, Mayo Clinic and Children's Mercy Hospital in Kansas City.

Patient selection: ages from 1 month to 23 years, on chronic peritoneal dialysis

Outcome: total body water in liters

Parameters:

(1) height in cm

(2) weight in kg

(3) gender

(4) body surface area in square meters (using the equation of Gehan and George)

total body water in liters for boys =

= (0.1 * (((height)*(weight))^0.68)) - (0.37 * (weight))

= (20.88 * (BSA in square meters)) - 4.29

total body water in liters for girls =

= (0.14 * (((height)*(weight))^0.64)) - (0.35 * (weight))

= (16.92 * (BSA in square meters)) - 1.81
