What is dialysis
Dialysis is a treatment that replaces the function of the kidneys , when they are compromised in their process of cleaning the blood. People who need this procedure is because they have kidney failure and although at first glance it seems simple, the dialysis process can be quite stressful and the side effects generate considerable discomfort for the patient. While dialysis occurs, the nephrologist will have placed the patient on a transplant list , when a compatible kidney appears, it will be the end of dialysis.
Types of dialysis
The function of the kidneys is to eliminate toxins and excess fluids from the blood, since the accumulation of these can be dangerous for our health. When this process cannot be accomplished, it will be necessary to help the kidneys through dialysis. There are two types of dialysis :
- Peritoneal dialysis : it is responsible for eliminating the remaining fluid, through the peritoneum, a membrane that covers the abdomen. In this case, a catheter is placed in the abdomen and filled with dialysis solution, which contains a type of sugar that will be responsible for removing waste, which will pass through the blood vessels through the peritoneum. To insert the catheter requires surgery , it will be placed near the navel. This treatment can be carried out at home, if you have the necessary material and prior medical authorization, which will give you greater independence.
- Hemodialysis : in this case the access is created in a blood vessel in the arm, where the blood passes through a filter that is divided into two parts, on the one hand the waste that the body does not need is extracted and on the other the blood returns to the body, already clean. This procedure is carried out in a medical center, three times a week for 3 to 4 hours .
Care after a dialysis session
After a dialysis session, it is normal for the following symptoms to appear:
- Soft spot.
- Changes in blood pressure
The care that must be taken after dialysis and throughout the process will be aimed at avoiding infections in the area where the catheter is located. Some of them are:
- Personal hygiene will be very important, using neutral soaps to avoid the itchiness of this disease.
- Keep the catheter hole covered.
- See your doctor if you see any change in the fistula.
- If you’re on hemodialysis and your arm feels swollen , hold it up for a while.
- Avoid straining your arm where you have the fistula.
- Don’t sleep on the side where the catheter is.
The complications of dialysis They are not very frequent, however there are many risks of infections:
- Peritonitis : since peritoneal dialysis is carried out inside the body, there is a very high risk that the peritoneum will become inflamed, this infection usually responds to treatment with antibiotics.
- Infection of the fistula : the puncture to create the access in the blood vessel must be done between three and four times a week, so the risk of infection is quite high.
- Blockage of blood vessels : Continuous puncture can generate thrombi that render the blood vessel unusable for dialysis. Surgery will need to be done to remove the obstruction.
- Diet : as the kidneys are not capable of carrying out their function, patients with kidney failure must take good care of their diet and the amount of fluid they consume.
- Arteriosclerosis : people with kidney failure have an accumulation of phosphates in the blood, which causes damage to the blood vessels and disorders such as arteriosclerosis can appear.
