Peritoneal dialysis is mainly through the peritoneal dialysis fluid constantly replaced in order to achieve the removal of metabolites, toxic substances and correct water, electrolyte balance disorder purposes. Then peritoneal dialysis is not no side effects? No, peritoneal dialysis prone to complications. What are the complications?
Dialysis for 3 Months: Can I Still Get Rid of Dialysis
The first complication: peritonitisOver the past 20 years, with the improvement of peritoneal dialysis connection technology, as well as the importance of care at the exit, the incidence of peritoneal dialysis-related infection has decreased significantly, peritonitis is no longer inevitable. There is still more common bacterial infection. Infected bacteria can come from the exit, blood, intestine or dialysis solution. If abdominal pain, fever, dialysis fluid color change and white blood cells increased to 100 / mm3 dialysis fluid examination of bacteria (should pay attention to anaerobic infections), can confirm the diagnosis. Peritonitis can cause serious loss of protein, peritoneal adhesions, thickening, leading to peritoneal dialysis failure, catheter blockage, and even life-threatening. The implementation of peritonitis should use appropriate antibiotics, the latest International Society of Peritoneal Dialysis in 2005 issued the latest treatment guidelines, the principle is to include early treatment, according to experience and pathogen culture results choose a reasonable antibiotic, residual renal function must be protected. Clinical manifestations: abdominal pain, chills, fever, abdominal tenderness. Care methods: dialysis solution 1000ml continuous washing 3.5 times, temporarily changed to IPD, abdominal fluid into the antibiotics and heparin, etc., the body for antibiotics, if after 24 weeks of infection can not control, should consider pulling out dialysis tube.
What Makes Bone Hurt After Dialysis
The second complication: abdominal pain
Hyperosmotic dialysate, dialysate temperature is too low or too high, too much fluid into the abdominal cavity or into the air too much, dialysis solution PH improper, abdominal infection, catheter shift stimulation can cause abdominal pain. Should pay attention to adjust the temperature of dialysis solution to reduce the osmotic pressure of dialysate and dialysate access to the speed of the treatment should be removed from the reasons, and in the dialysis solution by adding 1% ~ 2% procaine 3 ~ 10ml, invalid Time to reduce the number of dialysis.
Notes on Kidney Failure and Dialysis
The third complication: dialysis tube drainage is poor or dialysis tube blockage
Due to catheter shift or twist, fibrin, blood clots or omentum fat obstruction, intestinal or abdominal cavity gas too much, dialysis after intestinal adhesion, dialysis tube end of the hole is partially exposed to the surface of the liquid in the abdominal cavity, resulting in siphon The function disappears. (1) can be used to change the position or semi-recumbent position, massage the abdomen. (2) spasm bladder bladder. (3) taking cathartic enema or enema, promote peristalsis. (4) peritoneal dialysis tube into heparin, urokinase, saline, dialysate, etc., and indwelling 30 to 60 minutes, can block the fiber block dissolved. (5) obvious abdominal distension can give a small dose of neostigmine, intraperitoneal injection of 500ml dialysate, and then take the semi-recumbent, in order to restore siphon effect. Such as invalid, can be strictly sterilized, into the hard dialysis tube core, dredge dialysis tube. (6) can not be complex, can be X-ray fluoroscopy to adjust the location of the dialysis tube or re-implantation dialysis tube.
Why Does Confusion Occur in Dialysis Patients
The fourth complication: excessive water or pulmonary edema
Early dialysis due to patients with significant azotemia, such as continuous use of high concentrations of glucose dialysate dehydration, plasma osmotic pressure is often higher than the dialysis fluid osmotic pressure, once changed to conventional dialysate, can lead to water retention, and even occur Risk of pulmonary edema.
