Renal insufficiency, PP films for Haemodialysis, APD & CAPD
Chronic renal insufficiency is a pathology that affects an increasing number of people. Currently, there are two treatment options available. Patients can choose between two dialysis procedures, peritoneal dialysis, and hemodialysis. Although often opposed, the two techniques are complementary in a long-term therapeutic strategy and can be used successively. They are generally selected according to the patient’s preference, ability to manage the treatment, age, and health status. However, when the patient is waiting for a transplant, peritoneal dialysis is preferred.
Peritoneal dialysis is performed in three stages via a dialysis catheter placed in the patient’s abdomen. The double membrane of the abdomen acts as a filter, making this permanent access to the peritoneal cavity essential. The first step is to connect a drainage bag to the catheter in order to remove the old, waste-saturated solution. Then comes the filling of the abdominal cavity with dialysate, a solution composed of water, sodium and electrolytes, followed by stasis. During this period, the dialysate collects the waste substances and eliminates them from the body. Continuous ambulatory peritoneal dialysis is performed on average 4 times a day in a manual way, while automated peritoneal dialysis is done by a machine that performs the exchange, most often during the night at the patient’s home. In both cases, hygienic and aseptic guidelines must be strictly observed to perform the treatment procedure safely.
Hemodialysis works differently and is most often performed in a dialysis center. It consists of supplementing the deficient kidneys by purifying the blood of its toxins thanks to a machine called a dialyzer.
However, this technique requires a vascular access to facilitate the aspiration of the blood towards the dialyzer and its return once purified. This involves a minor surgical procedure. Called arteriovenous fistula or shunt, it consists in connecting an artery and a superficial vein of the forearm.
The flexible bags find their usage at different levels, whether for peritoneal dialysis or hemodialysis. They contain the dialysate and collect the toxin filled solutions during drainage. Made of polypropylene, they come with one or two compartments, and must meet the requirements to avoid any risk of complications such as peritonitis, and septicemia.
The coextruded films and the tubes developed by Polycine are autoclavable and, thanks to their innovative manufacturing process , are totally adapted to this type of application. Our APP198 film , characterized by an important gas barrier property, allows the manufacturing of the bags that will contain the dialysate or the cleaning solutions (citric acid) of the hemodialysis machines. APP200 film is suitable for the manufacture of drainage bags that collect used fluids.
For haemodialysates (pre-mix sodium bicarbonate) but also as a solution for cleaning the fluid channels of the haemodialysis machine (citric acid).
