Introduction
Peritoneal dialysis catheter removal generally refers to the procedure of removing the catheter after completion of peritoneal dialysis. The peritoneal dialysis catheter can be removed, but the procedure should be performed by a specialized physician in an operating room. The patient is placed in a supine position. The anesthesiologist administers local anesthesia near the catheter site, while the surgeon performs routine disinfection of the area around the catheter and drapes the field. After the anesthesia takes effect, the surgeon makes an incision at the catheter site using a scalpel.
Peritoneal dialysis catheter removal generally refers to the extraction of the catheter after completion of peritoneal dialysis. The peritoneal dialysis catheter can be removed, but the procedure should be performed by a specialized physician in an operating room. The specific steps are as follows:
1. The patient is placed in a supine position. The anesthesiologist administers local anesthesia around the catheter site, while the surgeon performs routine disinfection of the area and drapes the field.
2. After the anesthesia takes effect, the surgeon makes an incision at the catheter site using a scalpel and sequentially dissects through subcutaneous tissue and fat layers.
3. A hemostat is used to clamp the catheter and gently lift it upward. Following the direction of the lifted catheter, a dissecting clamp is used to separate surrounding tissues inward, the peritoneum encapsulating the catheter is incised, and then the intra-abdominal portion of the dialysis catheter is pulled out.
4. After removing the catheter, hemostasis is achieved at the wound site, followed by layered suturing of the subcutaneous tissues and skin.
If there is infection at the catheter exit site, the skin at the exit site is left unsutured; drainage is maintained for several days, along with effective antimicrobial therapy.
