haemodialysis

Yesterday I went to the hospital to visit one of my relatives who is very ill. During the visiting time he is having haemodialysis and I saw the machines around him that is so interesting.That's why I go and search the net how it actually function.
Curious me..haha^^

So, what is Haemodialysis?
In medicine, hemodialysis (also haemodialysis) is a method that is used to achieve the extracorporeal removal of waste products such as creatinine and urea and free water from the blood when the kidneys are in a state of renal failure. Hemodialysis is one of three renal replacement therapies (the other two being renal transplant and peritoneal dialysis). An alternative method for extracorporeal separation of blood components such as plasma or cells is apheresis.

Hemodialysis can be an outpatient or inpatient therapy. Routine hemodialysis is conducted in a dialysis outpatient facility, either a purpose built room in a hospital or a dedicated, stand alone clinic. Less frequently hemodialysis is done at home. Dialysis treatments in a clinic are initiated and managed by specialized staff made up of nurses and technicians; dialysis treatments at home can be self initiated and managed or done jointly with the assistance of a trained helper who is usually a family member.

well there are two ways of doing a surgery before dialysis
1.AV(arteriovenous) fistula ~~recognized as the preferred access method.


2.AV (arteriovenous) graft ~~are much like fistulas in most respects, except that an artificial vessel is used to join the artery and vein. AV grafts are at high risk to develop narrowing, especially in the vein just downstream from where the graft has been sewn to the vein. Narrowing often leads to thrombosis (clotting). As foreign material, they are at greater risk for becoming infected. More options for sites to place a graft are available, because the graft can be made quite long. Thus a graft can be placed in the thigh or even the neck (the 'necklace graft')


Here's a video I found on youtube about how the machine works, it is really interesting
