With the advancement of medical technology, peritoneal dialysis (PD) has gradually become an important choice for care for patients with renal failure.According to the latest research, compared with traditional hemodialysis (HD), peritoneal dialysis showed a better success rate in the first two years. What secrets are hidden behind this?
Peritoneal dialysis uses the peritoneum of the patient's abdominal cavity as the dialysis membrane to remove excess fluid and metabolites from the body through special solutions. For patients who need long-term dialysis, this method shows better overall efficacy.
Operitoneal dialysis operating mechanism and benefits
The main principle of peritoneal dialysis is to introduce a specific dialysate into the body through a catheter placed in the abdomen. This dialysate contains sodium chloride, bicarbonate and a penetrating agent such as glucose.Patients can choose to perform continuous dialysis (continuous free peritoneal dialysis, CAPD) or use a machine for automatic dialysis (automatic peritoneal dialysis, APD) at night.Compared with hemodialysis, the most attractive advantage of peritoneal dialysis is its flexibility and high tolerance, especially for patients with heart disease.
Compared with the prescribed time and place for hemodialysis, peritoneal dialysis allows patients to perform at home. This design promotes the quality of life of patients and reduces the burden of seeking medical treatment.
Potential complications and their effects
Although peritoneal dialysis has many advantages, it is not without risk.Possible complications include peritonitis, catheter blockage, and abdominal bleeding.Therefore, doctors usually do detailed evaluations before peritoneal dialysis to ensure that the patient is suitable for this treatment.This treatment is not recommended for patients with major abdominal surgery or severe intestinal disease.
Control infection is an important management method in peritoneal dialysis. Many infection problems come from improper operation and lack of hygiene measures.
Peritoneal dialysis usage around the world
According to statistics, the use of peritoneal dialysis worldwide is quite uneven.In 2017, 96% of countries provided hemodialysis, but only 75% provided peritoneal dialysis.In some areas, such as Hong Kong, the usage rate of peritoneal dialysis is as high as 71.9%.In the United States, due to the large number of hemodialysis centers, the acceptance of peritoneal dialysis is relatively low.But with the change of Medicaid policies, the acceptance of peritoneal dialysis is gradually increasing.
In Mexico, the use of peritoneal dialysis reaches 55.9%, showing that local policies and medical resources can have a profound impact on dialysis models.
Possibilities and trends of future dialysis
With the continuous development of medical technology, peritoneal dialysis technology will continue to advance, and new dialysate and improved equipment are expected to further reduce the risk of complications while improving the effectiveness of treatment.Patients will also benefit from better educational resources and support systems to ensure the safety of the dialysis process.
In the future, whether peritoneal dialysis can be made a more common choice and widely promoted globally will depend on the in-depth research and policy support.
As our understanding of peritoneal dialysis continues to deepen, the advantages of this therapy are becoming more and more obvious.However, how do patients who choose drugs or dialysis ensure that they get the most suitable treatment?
