DIFFERENCE BETWEEN HEMODIALYSIS AND PERITONEAL DIALYSIS
Patients with chronic and acute renal failure may need to resort to a rather complex therapeutic technique known by dialysis.
The kidneys perform a function of fundamental importance for our body, removing waste and excess substances through the urine.
It follows that when our kidneys fail to perform this task, we can face even severe complications (or death), which in some cases make dialysis necessary.
Let's explore the topic together. Dr. Q Khan provides the best nephrology physicians in the USA. Trying to understand what dialysis is and the difference between hemodialysis and peritoneal dialysis, which are the two most common methods of execution.
Dialysis is a reasonably current therapy, which became common only in the 60s of the twentieth century.
As mentioned before, the kidneys filter the waste present in the blood, then excrete it through the urine, but damage to our body occurs when this process does not happen correctly.
Dialysis intervenes in the most severe cases of renal insufficiency when our kidneys are unable to perform their tasks sufficiently, more precisely when the function is impaired for about 85-90%.
What is it for? We could say that dialysis is a therapy that replaces the intervention of damaged kidneys to filter and remove excess fluids and toxins present in the blood.
Let's take a closer look at them.
As the name suggests, hemodialysis is a way of performing dialysis that involves blood directly.
Specifically, through the use of an instrument called a dialyzer, the blood circulating in our body is taken, made to flow inside this machine, passed through a filter containing a liquid called dialysate, and then returned, now purified, in the body of the sick patient.
So, wanting to simplify as much as possible, we could say that hemodialysis consists in cleaning the blood that the kidneys are now unable to carry out, leaving the task to a sort of artificial kidney.
This procedure can only be carried out in a dedicated facility, on average, three times a week and takes about 4-5 hours per session.
Patients with renal insufficiency who have to undergo hemodialysis see their lives significantly disrupted.
Our body has a membrane inside it, called the peritoneum, which lines the abdominal cavity and covers the organs it contains.
This membrane can act as a natural filter, used precisely in peritoneal dialysis.
How does it work?
The peritoneal membrane is very rich in blood vessels and capillaries. Also, it has excellent pores, perfect for the filtering action otherwise carried out by the kidneys or, in hemodialysis, by the external filter.
Then, an incision is made in the abdomen, a small catheter is inserted, and through it, the dialysate fluid, composed of salt and glucose, is made to flow into the peritoneal membrane. In contact with the membrane, this liquid captures the waste, after which it is released and collected in another bag.
This practice can also be performed at home and is divided into two ways:
Manual peritoneal dialysis, which is performed during the day by the patient or by the staff of the center, with a change of fluid about 4-5 times in 24 hours;
Automated peritoneal dialysis is based on using a device that performs multiple exchanges during the night while the subject is asleep.
This is an increasingly popular technique among patients with renal insufficiency.
We have seen that the two ways of performing dialysis have some substantial differences.
In particular:
In hemodialysis, blood is transferred from the body to a dialyzer which filters it. This is a therapy to be performed about three times a week, at a specialized center;
In peritoneal dialysis, the peritoneum is used as a natural filter. It can be performed at home, even without the intervention of a specialized technician.
It is important to remember that the two modes guarantee equivalent results. Hence, the choice results from a series of specific assessments linked to the preferences.
Hemodialysis takes three days a week but leaves total freedom for the remaining four days, but it is more of a lengthy procedure that cannot be performed independently.
On the other hand, Peritoneal dialysis must be done every day (or night) but leaves the patient free to move, go to work, guaranteeing a little more "normality" and can be carried out at home independently.
In the choice, the patient is supported by his nephrologist, which will indicate the best solution.
Surgical intervention
Fees of the surgeon, the assistant, the assistant, the anesthetist, and any other person are participating in the intervention (resulting from the operating report), operating room fees, and intervention material, including end prostheses.
Medical assistance, medicines, treatments
Medical and nursing services, medical-specialist consultations, medicines, examinations, diagnostic tests, physiotherapy, and rehabilitation treatments during hospitalization.
Accompanying person
Board and overnight stay for the accompanying person in the health institute or a hotel.
In the case of hospitalization in a health institution not affiliated with Unsalted for the Enfea Salute Fund.
Post hospitalization
Diagnostic tests and examinations, medical, surgical, and nursing services (the latter if the request is certified at the time of discharge from the health institution). Dr. Q Khan provides the best Clinical Consultation in the USA. Spa treatments (excluding hotel expenses in any case), carried out in 30 days after the termination of hospitalization, provided they are made necessary by the illness or accident that led to the hospitalization.
