Importance of Clinical Monitoring
Modelling a PD prescription is not an exact science; it is based on generalized formulas and assumptions. The output of a modeled prescription is limited in its accuracy and cannot account for the variability seen in individual patients. It is essential that the patient be closely monitored and their prescription adjusted according to clinical parameters in order to ensure the adequacy of a PD prescription.
1. Monitoring of the initial prescription may include
  • Achieved ultrafiltration
  • Achieved total fluid removal (UF + Urine)
  • Changes in body weight
  • Clinical signs of overhydration or dehydration
  • Monitor serum values (e.g. potassium)
  • Clinical signs of increased intra abdominal pressure
  • Clinical signs of inadequate clearance (uremic symptoms)
  • Thorough comprehensive clinical evaluation of the patient
 
2. Evaluation after 4 to 8 weeks may include
  • PET or PFT
  • Determine transport status
  • Determine daily ultrafiltration
  • Determine residual urine output and GFR in 24-hour urine collection
  • Determine renal and peritoneal Kt/V
  • Consider measuring the patient's intraperitoneal pressure
  • Comprehensive clinical evaluation of the patient
