Qualified nurses only Dialysis requires special training because of the complex technology. The consequences of making a mistake can be fatal. Both abdominal and renal dialyses require the understanding of certain scientific principles with the acquisition of technical skills. Nurses must be certified in the type of dialysis they are performing. Most nurses certified in the renal method are also certified in the abdominal. The reverse is not always true. Many floor nurses receive the additional training for abdominal dialysis without learning the hemodialysis process. Hemodialysis requires a higher level of technical skill, so if you or a loved one is scheduled for dialysis, ask the nurse if he or she has a certificate of completion from a dialysis course.
