Peritoneal dialysis

Peritoneal dialysis (synonym peritoneal lavage) - method of removal from the patient's organism of toxic products of metabolism with the help of dialysis solution.
The indication to the peritoneal dialysis are acute and chronic renal failure. The method is based on using a semi-permeable properties peritoneum (see Dialysis) and consists of washing the patient's abdominal cavity with a solution of a special composition (dialysis solution). In the majority of dialysis solutions include glucose, novocaine, antibiotics, sodium chloride, potassium chloride, calcium chloride, sodium bicarbonate, magnesium chloride.

Peritoneal dialysis: left - introduction dialysis solution, right - drain fluid from the abdomen.

Known peritoneal dialysis two types: continuous and fractional. For peritoneal dialysis in the abdominal cavity by means of trocar or through laparotomy enter PVC catheter. The catheter attached tee, with one end connected to a vessel containing a sterile dialysis solution (strengthened on the rack above the bed), and the other with a vessel on the floor beside the bed (Fig). The tube leading down to the lower vessel overlap. From the top of the vessel in the abdomen enter 2 litres of heated solution and place the clip on leading up. An hour later remove the clip from the discharge tube and dialysis solution flowing at the bottom of the vessel.
The procedure continues in total not more than 20 hours. During peritoneal dialysis is necessary to accurately measure the amount of fluid that drains from the abdominal cavity, in order to avoid accumulation of solution. After peritoneal dialysis catheter is removed from the abdomen.
