13 Technical Aspects and Prescription of Peritoneal Dialysis in Children lent of nitrogen appearance (nPNA), taking dialysate protein losses into account Body composition of children on PD can be evaluated by means of bioelectrical impedance 217 analysis (BIA) Specific equations to predict fat- free mass (FFM) and TBW from BIA data have been provided and are as follows [162]: FFM kg 0.65 height / impedance ohms / cm 0.68 age years 0.15 TBW L 0.144 impedance / height The first measurement of PD dose can be obtained as early as 1 week after the patient is stabilized on a defined PD prescription Subsequently, PD dose measurements can be completed every 3 months and in the event of any significant change in clinical status and/or in the amount of residual diuresis A PET can be performed 1 month after chronic PD initiation and then repeated every 12 months or earlier in case of unexpected changes in delivered PD dose or if any clinical condition that could permanently affect the peritoneal transport properties occurs, such as recurrent or persistent peritonitis In the clinical setting, routine clinical and biochemical outcome evaluations in pediatric patients on stable chronic PD can be organized according to the following timetable Every Month • Clinical and physical examination • Height/length • Weight • Head circumference (in infants and toddlers) • Blood pressure • Blood urea nitrogen and creatinine • Sodium, potassium, acid-base status • Hemoglobin/hematocrit • Serum albumin, serum calcium, phosphorus, and magnesium • Daily urine volume and UF Every 3 Months • Serum ferritin • Serum iron • Total iron binding capacity • Alkaline phosphatase • Parathyroid hormone ohms / cm 40 weiight kg 1.99 • 25-Hydroxyvitamin D • Kt/Vurea and CrCl from a 24-h dialysate and urine collection Every 12 Months • Ambulatory blood pressure monitoring • Echocardiography • Hand and wrist x-ray for bone age • Neurodevelopment assessment (every 6 months in children
