Haemodialysis is a treatment that uses a machine and dialyzer to purify blood, removing waste and excess fluids. The process typically occurs in hospitals or dialysis centres, usually three times a week for about four hours per session.<\/span><\/p>How Haemodialysis Works:<\/b><\/p>- Blood Pumping:<\/b> Blood is pumped from the body to the dialyzer via tubing. Heparin or saline prevents clotting.<\/span><\/li>
- Dialyzer Function:<\/b> The dialyzer (artificial kidney) filters blood through a semi-permeable membrane, using a special solution called dialysate.<\/span><\/li>
- Returning Blood:<\/b> Cleaned blood is then returned to the body.<\/span><\/li><\/ol>
Types of Vascular Access:<\/b><\/p>- Central Venous Catheter:<\/b> Used for short-term access, inserted into a large vein in the neck, chest, or leg. Ideal for immediate use but less preferred for long-term.<\/span><\/li>
- AV Fistula:<\/b> A long-term access option created by connecting an artery to a vein in the arm. It requires time to mature but is more durable and less prone to complications.<\/span><\/li>
- AV Graft:<\/b> For patients who can\u2019t use an AV fistula, a synthetic tube connects an artery and vein. It is less durable and more prone to complications than an AV fistula.<\/span><\/li><\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
