How to change the picture of peritoneal dialysis tube?

summary

A peritoneal dialysis tube is composed of a catheter, a lead wire and a silk sleeve. The insertion end of the catheter is provided with a side hole, which is characterized in that the insertion end is provided with two arms, which are Y-shaped, and the included angle between the two arms is 40 °。 How to change the picture of peritoneal dialysis tube? Let's talk about it.

How to change the picture of peritoneal dialysis tube?

It usually occurs after catheter implantation, and the symptom is wet dressing at the outlet. Injection of contrast medium into abdominal cavity and CT scan can make a definite diagnosis. In treatment, peritoneal dialysis fluid should be drained, the peritoneal cavity should be emptied, and dialysis should be stopped for at least 24-48 hours. The longer the emptying time is, the greater the chance of leakage healing is. If it is invalid, the catheter should be removed and re implanted in other parts. It should be noted that ligation at the outlet of the leakage is not helpful to the treatment, on the contrary, it can make the leakage into the surrounding subcutaneous tissue.

The placement of peritoneal dialysis catheter on the body surface is a very important step to establish a smooth peritoneal dialysis access. In order to keep the peritoneal dialysis drainage unobstructed and reduce the incidence of catheter complications, we must be familiar with the anatomical structure of the anterior abdominal wall and select the most appropriate placement point of peritoneal dialysis catheter. The skin incision on the surface of the catheter is usually placed in the midline or 3 cm below the umbilicus near the midline. The former is simple and easy to master, but the latter may reduce skin outlet leakage and abdominal wall hernia, so it is more commonly used. In addition, patients with high stature can choose the left median incision, patients with short stature can choose the right median incision, and patients with active sexual life can choose the corresponding position of left lower abdomen on the opposite side of Maishi point.

At present, there are three methods of tube implantation: direct vision surgical incision, blind puncture and peritoneoscopic catheterization. All methods can be performed by a nephrologist or surgeon. Direct vision surgical incision: please refer to "peritoneal dialysis therapeutics" edited by Yu Xueqing, science and Technology Literature Press. Blind puncture method: puncture the umbilical cord and pubic symphysis line 1 / 3 with trocar, and then send the dialysis tube into the peritoneal rectovesical fossa through trocar, or cut the peritoneum in different layers, and insert the peritoneal dialysis tube into the rectal bladder fossa, Dialysis can be performed. This way is easy to damage the internal organs, which is dangerous. This method has been rarely used in clinic.

matters needing attention

Too much salt should lead to * retention of water. Daily salt should be less than 3 G, avoid high salt food, such as pickled products, soy sauce, avoid using chicken essence, monosodium glutamate and other high salt seasoning, can choose low sodium salt, cooking can add more seasoning, such as green pepper, pepper, pepper, pepper, lemon, onion, ginger, garlic, onion, increase the taste of food.
