Your Child & Chronic Kidney Disease - Glossary
Albumin – The main protein within the blood stream.
Alphacalcidol – Drug (active vitamin D) used to increase calcium absorption.
Ametop – used to numb the skin before taking blood
Anaemia – A condition in which there is a reduction in the haemoglobin concentration – the blood. This can cause paleness, weakness and fatigue.
Antibiotic – A drug used to combat infection.
Antihypertensives – Drugs used to control high blood pressure (eg. Nifedipine,Atenolol, Propranolol, Enalapril).
APD – Automatic Peritoneal Dialysis.
Artery – Vessel carrying blood away from the heart. Part of the circulatory system.
Artificial kidney – used in haemodialysis to filter waste products and excess fluid from the blood stream.
Artificial kidney machine – (haemodialysis machine). A machine which supports and monitors the function of the artificial kidney.
Aseptic technique – The use of sterile procedures to prevent bacteria from entering the body, thus limiting the risk of infection.
Azathioprine (Imuran) – drug used to prevent rejection of the kidney transplant. Lowers white blood cell levels in the blood stream.
Biopsy – Removal of a tiny piece of kidney tissue for special examination under the microscope.
Bladder – The sac in which urine produced by the kidneys is collected and stored until it is released from the body.
Blood Pressure – The pulsating pressure of blood flow through an artery.
Calcium – A mineral that is important for bone growth and body functioning.
Calcium Carbonate – Drug to reduce the uptake of phosphate from the gut.
CAPD – Continuous Ambulatory Peritoneal Dialysis.
CCPD – Continuous Cycling Peritoneal Dialysis.
Chronic kidney disease (CKD) – A gradual reduction in kidney function that occurs over months or years, and results in the build up of waste products. Stages 1-5 with 1 mild and 5 severe.
Contaminate – to make an accidental failure in aseptic technique.
Creatinine – A waste product in the blood produced by the breakdown of normal body tissues. It is removed from the blood stream by the kidneys.
Cyclosporin – Drug used to prevent rejection of transplants.
Dialysis – Process of removing waste products and excess waste from the blood stream.
Diastolic – The lower number in a blood pressure measurement.
Diffusion – Passage of particles from a solution of high concentration to a solution of low concentration.
Dry (or ideal) weight – The weight at which blood pressure is normal and no swelling (oedema) is present.
Electrolytes – include sodium, potassium, chloride and bicarbonate and usually measured together in the blood.
EMLA cream – Used to numb the skin before taking blood or giving an injection
End stage renal disease (ESRD) – The stage of poor kidney function that requires dialysis or transplantation to maintain life and health.
Erythropoietin (EPO) – A hormone that increases the number of red blood cells and which is normally produced by the kidney. Artificial hormone may now be given by injection to correct anaemia.
Fibrin – Strands of protein sometimes found in peritoneal dialysis fluid.
Fistula – Created surgically by joining an artery and a vein. The vein then ‘matures’ or dilates and provides a route to supply and return blood during dialysis.
Gastrostomy – Feeding tube or button inserted directly into the stomach.
Haemodialysis – The process by which excess body wastes and fluid are removed from the blood when passing through an artificial kidney.
Haemoglobin – The pigment in red blood cells that carries oxygen from the lungs to the tissue.
Heparin – A ‘blood thinner’ or anticoagulant used during dialysis to slow blood clotting or prevent fibrin problems.
Hypertension – High blood pressure.
Hypotension – Low blood pressure.
Immunosuppression – Use of drugs such as tacrolimus, MMF, azathioprine and prednisolone to damp down the body’s response to the transplant kidney.
Isotope scan – requires a special injection into a vein and will show how the kidney(s) is functioning.
IPD – Intermittent Peritoneal Dialysis. Jugular catheter – plastic tube placed into a large vein in the neck and used for haemodialysis. Also used for taking blood samples and giving fluids.
Kidney – One of the two organs which produce urine. Located at the back of the abdominal cavity on each side of the spinal column.
Lignocaine – Local anaesthetic.
MMF – Mycophenolate Moletil – drug used to prevent rejects of transplants.
Metabolism – Process by which foods are broken down and used for body energy and function.
Monitor – An electronic device used to check, remind, or warn.
Nasogastric – Tube passed through the nose into the stomach
Nephrectomy – Surgical removal of a kidney
Nephron – The functional unit of the kidney which acts to maintain the body’s chemical balance. There are approximately one million nephrons in each kidney.
Oedema (Swelling) – An abnormal accumulation of fluid in the tissues, specially noticeable around the ankles, face (particularly the eyelids), and sometimes the abdomen.
Paediatric Dialyist – Vital mineral supplement Peritoneal cavity – Space where peritoneal dialysis occurs.
Peritoneum – A porous lining surrounding the peritoneal cavity, through which water and waste products pass during peritoneal dialysis.
Peritonitis – Infection in the peritoneal cavity.
Phosphate – A mineral important for bone growth and body functioning. In chronic kidney disease there is a build up of phosphate in the body.
Phosphate binders – tablets used to reduce the level of phosphate in the blood. Taken with meals.
Plasma – The fluid portion of the blood.
Potassium – An electrolyte necessary to the body, but harmful when found in excess.
Prednisolone (Steroid) – drug used to reduce inflammation in the kidneys and to prevent and treat rejection. Also used to treat some causes of renal failure.
PTH – Parathyroid hormone which regulates bone health
Rejection – A vigorous response of the body’s own cells to the renal transplant.
Renal – Referring to the kidney.
Saline – A salt water solution.
Sodium (Salt) – A mineral which helps regulate the fluid content in the body.
Systolic – The top number in a blood pressure measurement.
Sytron – oral iron solution.
Tacrolimus – drug used to prevent rejection
Tenckhoff catheter – silicon rubber tube placed in the peritoneal cavity for peritoneal dialysis.
Thrill – vibration or buzzing sensation felt over the vein of a cannula or fistula.
Ultrafiltration – The process of removing water from the blood during dialysis.
Ultrasound scan – A painless procedure which tells us the size and structure of the kidneys. Often done at the time of kidney biopsy.
Ureter – A tube which carries urine from each kidney to the bladder.
Urethra – The canal for the discharge of urine from the bladder.
Urea – The waste product in blood which is produced from protein breakdown.
Vein – A blood vessel which carries blood back to the heart from other parts of the body.
Venous – Referring to veins and the flow of blood to the heart.
Vitamins – Essential substances needed for proper body functioning.
