Solute clearance targets and measurements in children on maintenance peritoneal

Targets and measurements
The minimal delivered dose of total (peritoneal and kidney) small-solute clearance should be a Kt/Vurea of at least 1.8/week
Total solute clearance should be measured in a clinically stable patient:
➔ within the first month after dialysis has been initiated
➔ at least once every 6 months thereafter (but in patients with residual renal function 24 h urine collection for determination of volume and solute clearance should be obtained at a minimum of every 3 months)
➔ more frequently when clinical events are likely to have resulted in decreased clearance or when new/worsening signs or symptoms of uraemia develop
➔ at least 1 month after resolution of an episode of peritonitis
➔ if a patient is not doing well and has no other identifiable cause other than kidney failure
When calculating Kt/Vurea, V, or total body water, should be estimated by using gender-specific nomograms based upon equations that include the patient’s height and weight [77]
