Rather than using a machine, peritoneal dialysis uses the lining on the inside of the belly as a natural filter for blood. Adequacy of dialysis can be measured with urea kinetic modeling (Kt/V) or urea clearance. Hernia. If the catheter has to be used early, then low volumes should be used (start with 1 liter) in the supine position (e.g., APD with a dry day), with the patient instructed not to mobilize while dialysate is in the peritoneal cavity during the first 2 weeks after catheter insertion. Peritoneal dialysis (PD) is associated with a number of potential complications that affect technique and patient survival. glucose concentration is higher than the patient’s blood glucose concentration, and this can be confirmed by scintigraphy after intraperitoneal instillation of isotope, usually, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on Google+ (Opens in new window), Optimal Timing and Placement of the Peritoneal Dialysis Catheter, Bone and Mineral Metabolism in Chronic Kidney Disease, Fanconi Syndrome and Other Proximal Tubule Disorders, Comprehensive Clinical Nephrology Expert Consult, Antibiotic Regimens for Bacterial PD Peritonitis, Enterococci (including vancomycin-resistant enterococci). It is technically simple and, when necessary, can be performed continuously in BMC Nephrology 18 (312). Retrieved February 24, 2019, from https://www.homedialysis.org/life-at-home/articles/hernias-and-peritoneal-dialysis. (vi) Fujiwara, M., Soda, T., Okada, T., Kanamaru, H., Inoue, T., & Ogawa, O. The procedure is performed at home and primarily works to remove excess fluid and waste products from the blood. Soon after starting PD, patients may experience pain during fluid inflow, and occasionally pain affects the shoulders and is pleuritic in nature, possibly because of diaphragmatic irritation, which usually resolves over the following days. Introduction Peritoneal dialysis (PD) is generally considered the optimal dialysis modality for neonates. (2018, March 22). Excess pressure and weight in the abdomen can put undue pressure on spinal nerves to cause back pain. Retrieved February 24, 2019, from https://www.niddk.nih.gov/health-information/kidney-disease/kidney-failure/peritoneal-dialysis/dose-adequacy. In contrast, genital edema suggests an inguinal hernia or patent processus vaginalis. Bowel perforation by a peritoneal dialysis catheter: Report of two cases. The first time this happens, a sample must be sent to the microbiology laboratory to exclude infection. Peritoneal dialysis: Dose & adequacy. If one can be confident that the pleural effusion is not caused by the PD, then PD can be continued while the effusion is investigated and managed. Subsequently, bowel action should be kept regular by increasing the fiber in the diet and, if necessary, adding a mild laxative. All antibiotic regimens should be developed in consultation with local microbiology practices. A small number of patients have fibrin formation in the absence of peritonitis. Sometimes the catheter becomes wrapped in omentum, suggested usually by complete inflow and outflow failure. One of the most common side effect of this type of kidney dialysis is a condition known as peritonitis wherein the peritoneum gets infected due to bacterial infection. The dialysis catheter that is inserted into the belly of a patient who opts for peritoneal dialysis, called the PD catheter, is often the Achilles' heel of the PD patient. These complications can be separated into mechanical aspects relating to the PD technique and the catheter itself, infections either at the exit site of the catheter or peritonitis, changes affecting the peritoneal membrane, and metabolic consequences that arise from components of the dialysis solutions—predominantly the glucose content. Complications of Peritoneal Dialysis The main complication of PD remains peritonitis, which is responsible for the most cases of method failure. Chapter 97 Obstruction is another mechanical complication associated with PD catheters. The diagnosis is confirmed by finding more than 100 white blood cells/mm3 (1 × 107 cells/l). Peritoneal Dialysis Presentations Home Dialysis Lecture Series Session 3: PD Prescriptions & Complications Home Dialysis Lecture Series Session 2: PD Catheters 101 PD patients affected by this complication may notice that their clothing or dressing around the dialysis access is wet following a PD exchange. Some patients have discomfort or even pain when the fluid is drained out, which can be experienced in the genital area or rectum, and is commonly a result of pelvic irritation related to the catheter tip. From a therapeutic point of view, it is important to differentiate between infections at the e… Routine use of antibiotics is not necessary. (v) Home Dialysis Central. Peritoneal dialysis (PD) is one of the two types of dialysis (removal of waste and excess water from the blood) that is used to treat people with kidney failure. In PD, the process of dialysis takes place inside the body. Peritonitis is one of the few complications associated with peritoneal dialysis.  The peritoneum is the thin membrane that lines your... Beginning dialysis can be stressful and overwhelming. Automated peritoneal dialysis is a broad term that refers to all forms of peritoneal dialysis that utilize a mechanical device (called a cycler) for instillation and drainage of dialysis fluid. The problem usually resolves spontaneously and often is visible only in one outflow. Sources: (i) Akoh, J. People undergoing peritoneal dialysis can expect to experience peritonitis about once every 2 years. It is clear that the enthusiasm and experience of the operator are key determinants of catheter outcome,2 and international guidelines describe the optimal conditions for catheter insertion.3 Timing is also important: Patients randomized to the late start limb of the Initiating Dialysis Early and Late (IDEAL) study (estimated glomerular filtration rate [eGFR] 5 to 7 ml/min), as opposed to patients starting dialysis early (eGFR 10 to 14 ml/min), were less likely to start on PD despite it being their treatment of choice, probably because of delayed planning.4 Early catheter problems are more difficult to manage in the absence of residual kidney function. Although it was customary to transfer APD patients to CAPD for the purpose of treating peritonitis, this is no longer necessary. Loading of the bowel with fecal material is often obvious on a plain radiograph, but treatment for constipation should be initiated without recourse to this investigation because it is so common. The biggest difference in hemodialysis vs peritoneal dialysis is that hemodialysis requires an artificial kidney machine to filter blood while peritoneal dialysis does not. Various culture techniques have been proposed, but white cell lysis and inoculation into blood culture media is often helpful in increasing the yield of a positive growth. The most important and common complications of peritoneal dialysis (see table Complications of Renal Replacement Therapy) are. Complications of Peritoneal Dialysis Abhijit Kontamwar,MD Renal Consultants, Inc Clinical Assistant Professor of Internal Medicine at NEOUCOM (Northeastern Ohio Universities Colleges of Medicine and Pharmacy). If inflow is restored, heparin should be added to the dialysate for the next few cycles. Should the catheter remain blocked, a plain abdominal radiograph is required. Root cause analysis should be performed after each episode of PD peritonitis, with retraining as appropriate. Complications of peritoneal dialysis . If inflow is significantly slowed or even stopped completely, mechanical causes should be suspected. Dextrose is sugar—most of which may be absorbed by your body during each dialysis session. You may be able to prevent and relieve your back pain by performing exercises that strengthen the abdominal muscles.  If the prescribed amount of dialysate used during an exchange is contributing to your back pain, a modification to the PD prescription may be needed. Symptoms of perforation may include watery diarrhea, abdominal pain, fever, and signs of infection. Peritoneal dialysis (PD) is a procedure that can be used by people whose kidneys are no longer working effectively. If the radiograph shows the catheter to be malpositioned, an attempt should be made to reposition the catheter tip into the pelvis (Fig. This occurs more commonly on the right side. If the organism is methicillin-resistant Staphylococcus aureus (MRSA), vancomycin will be continued as part of the regimen. PD catheter complications can be safely and effectively treated by a vascular specialist at a vascular access center. There are also other complications which incorrect treated may lead to failure of the method: mechanical complications, abdominal wall defects, exit site and tunnel infections. Obstruction occurs when the PD catheter is placed too close to the intestine or when the catheter migrates to cause poor outflow of the dialysis solution. Reducing peritonitis rates requires a multifaceted, multidisciplinary approach based on the use of preventative measures around the time of catheter insertion, the use of modern disconnect systems, exit site management, and education of patients and health care professionals.9 This should be supported by regular local audit of peritonitis rates including causative organisms and local sensitivities, which is increasingly important because of the emergence of resistant organisms, and the requirement to use antibiotics effectively. You can get an infection of the skin around your catheter exit site or you can develop peritonitis, an infection in the fluid in your belly. The areas discussed include early complications such as surgical wound hemorrhage, bleeding from the catheter, intestinal perforation and urinary bladder perforation, dialysate leakage through the wound, as well as late complications including catheter kinking or occlusion, retention of fluid in the peritoneal recess, hernias and hydrothorax, and encapsulating peritoneal sclerosis. If you or a loved one is experiencing abdominal pain or any other symptoms you think may be related to your dialysis access, contact your nephrologist to obtain a referral to avascular access center immediately to discuss your treatment options. If the results of this testing prove negative, the patient can be reassured. Except for culture-negative episodes, empiric treatment is stopped once the sensitivities are known. Slow outflow can be a problem in patients using automated peritoneal dialysis (APD), resulting in excessive machine alarms. Retrieved February 24, 2019, from https://www.mayoclinic.org/tests-procedures/peritoneal-dialysis/about/pac-20384725. Peritoneal dialysis associated infections: An update on diagnosis and management. However, these individuals may be able to avoid the leaking of dialysis fluid by strengthening their abdominal walls with exercise and physical activity. (ii) National Institute of Diabetes and Digestive and Kidney Diseases. Infections of different hues may occur depending on the site. Complications Of Peritoneal Dialysis The main complication of this process comes from infection because of the presence of a permanent tube. 97-3, A). (iv) The leaking of dialysis fluid is one of the more common PD catheter complications. A surgical repair will be required if a major leak is visualized and should always be considered when there is a hernia. What’s the Difference Between a CVC and a PICC? Azura Vascular Care is devoted to helping you fully understand how to properly care for your dialysis access and can treat complications associated with PD. 7,10,14 Residual renal functioning can be monitored with urine creatinine clearance. (i) However, PD comes with its own set of non-infectious complications as well—many of which can be addressed promptly at a vascular access center. A hernia can occur shortly after PD catheter placement but more commonly occurs as a late complication one year following PD initiation. Before surgery, the abdomen is cleaned properly and a catheter is inserted surgically by keeping its one end in the abdomen and other being sticking out … Metabolic Complication of Peritoneal dialysis Yousaf khan Renal Dialysis Lecturer IPMS-KMU 2. (2016, July). Complications of PD catheters. (iii) This increases the risk of hernia. Back pain and infusion pain are commonly experienced by some PD patients. A pleural effusion can occur with generalized fluid overload or local lung disease, but it is occasionally caused by a leakage of dialysate through the diaphragm (Fig. All rights reserved. Causes include perforation of the intestinal tract, pancreatitis, pelvic inflammatory disease, stomach ulcer, cirrhosis, or a ruptured appendix. IVC Filter Placement and Removal Procedure, Angioplasty, Stent and Atherectomy Procedure, Paracentesis and Thoracentesis Procedures, contact your nephrologist to obtain a referral to avascular access center. Encapsulating Peritoneal Sclerosis and Renal Transplantation, 537 Although peritonitis is regarded as the Achilles heel of peritoneal dialysis (PD), a number of serious noninfectious complications can develop in patients on PD. Samples of the dialysate should be taken for cell count and microbiologic examination. Periotonitis is an infection of the peritoneum which brings symptoms such as severe abdominal pain, episodes of shivering, fever and vomiting. World Journal of Nephrology 1 (4):106-122. 6 Potential Non-Infectious Complications You May Experience with Peritoneal Dialysis Weight Gain. Around 18% of the infection-related mortality in PD patients is the result of peritonitis. A 2-liter bag of dialysate should take 15 minutes or less to run into the peritoneal cavity. cloudy, but on standing the fibrin will aggregate and the fluid becomes clear. (iv) Signs you may have a hernia include the sudden appearance of bumps or bulges in your belly, feeling a bulge in the groin area, and the leaking of PD fluid from the catheter exit site. It is normally caused by contamination of the dialysis tubing or extension of catheter exit site or tunnel infections. (iv), Perforation is one of the rarest PD catheter complications and occurs when the catheter pierces into the bladder, gallbladder, bowel, or another organ. Some of the noninfectious complications that occur in patients on continuous peritoneal dialysis (eg, continuous ambulatory peritoneal dialysis [CAPD] and continuous cycler peritoneal dialysis [CCPD]) are due to increased intra-abdominal pressure resulting from instillation of dialysate into the peritoneal cavity. 97-1). Weight gain. The dialysate leukocyte count will be affected by dwell length, and this needs to be taken into account in APD patients. Hernias and peritoneal dialysis. Peritoneal dialysis (PD) is associated with a risk for infection such as peritonitis, which is inflammation of the peritoneum, or the membrane lining of the abdominal wall. Peritoneal dialysis (PD) is an alternative procedure to chemodialysis for patients with severe chronic kidney disease. It does not cure or treat the underlying kidney disease. A Gram stain of the spun deposit should also be performed to help identify the type of causative organism, although initial treatment will usually be empiric pending culture and sensitivity results. Infections. Complications of peritoneal dialysis can include: 1. The mesothelial cells of the peritoneal membrane have a range of physiologic functions including the production of fibrinolytic agents such as tPA. Once the culture result is available, the regimen should be modified accordingly (Table 97-1). Peritonitis. This is can be managed by switching to tidal APD and using a relatively large residual volume, for example 25% to 50% of the fill volume. For CAPD, the antibiotic is administered as a loading dose in the first bag and then as a maintenance dose in subsequent bags. A. (iii) If you have a PD catheter and are gaining excess weight, talk to your nephrologist about changes you can make to your diet that can fight weight gain without compromising dialysis treatment. (iv) Incorrect PD catheter placement can also cause infusion pain, especially when the tip of the catheter touches the bladder, pelvic wall, or rectum. Isolated edema of the abdominal wall suggests an internal leak from the peritoneal cavity, either spontaneously or in association with a surgical hernia. Peritoneal dialysis has better outcomes than hemodialysis during the first couple of years. Complications may include infections within the abdomen, hernias, high blood sugar, bleeding in the abdomen, and blockage of … A leak is most simply indicated by aspirating a sample of the effusion and demonstrating that its glucose concentration is higher than the patient’s blood glucose concentration, and this can be confirmed by scintigraphy after intraperitoneal instillation of isotope, usually 99mTc-DTPA (Fig. There is sometimes a clear history of trauma to the abdomen or of unexpected strain. The risk of infection is greater if the person doing the dialysis isn't adequately trained. The treatment is to flush the abdomen with a few cycles of dialysate containing heparin (500 U/l) to minimize the chances of clotting in the catheter. (2012). Antibiotic regimens for bacterial PD peritonitis. by James Uden — Last updated: 2010-07-08 . Published literature does not give a strong indication that one insertion technique is better than another, although a recent meta-analysis suggested an advantage of the laparoscopic compared with the open surgical insertion technique1 (techniques of catheter insertion are further discussed in Chapters 92 and 96). It is rarely serious but causes considerable alarm to the patient. It is important that PD catheters be adequately immobilized if used for early start PD to reduce the risk of tugging and leak. 121 Peritoneal Dialysis 1081 † The adequacy of dialysis and assessment of the patient ’ s residual renal function should be evaluated on a periodic basis. Peritonitis symptoms and signs include abdominal pain, cloudy peritoneal … A leak of dialysate, which is confirmed by measuring glucose concentration in the leaking fluid, is a risk factor for infection. This can be done under radiologic screening with a sterile catheter guide although this is not widely practiced. These could be at the PD catheter exit site (the point where catheter emerges from the skin, called an exit site infection), along its "tunnel" (the course it takes underneath the skin and in the abdominal muscle, calle… Peritonitis, the major complication of peritoneal dialysis (PD), is associated with high morbidity and mortality. Guidelines for the diagnosis and management of PD peritonitis are published by the International Society for Peritoneal Dialysis (ISPD; www.ispd.org).10 The spectrum of peritonitis and its management in children have also recently been described in detail.11 The reader is directed to a detailed review on reducing peritonitis risk.9. On occasion, both can be present. Fluid leaks occur whereby dialysate leaks out of the peritoneal cavity—which can be either visible externally or not. An estimated 39% of catheter removals are related to persistent exit site and tunnel infections that are unresponsive to antibiotic therapy (,34). 5. Review potential complications of PD in neonates. These complications can be separated into mechanical aspects relating to the PD technique and the catheter itself, infections either at the exit site of the catheter or peritonitis, changes affecting the peritoneal membrane, and metabolic consequences that arise from components of the dialysis solutions—predominantly the glucose content. Patients should be advised to contact their dialysis unit immediately if they observe a cloudy bag or develop persistent abdominal pain. Global utilization of peritoneal dialysis ranges from 6% to 91% in various parts of the world. Call 866.996.9729 to schedule an appointment with a vascular specialist today. This complication can often be corrected by PD catheter repositioning and, in some cases, a surgical revision will be needed. (v). 97-3, B). The dialysate contains sugar (dextrose). Catheter-related infections frequently lead to abandonment of CAPD. It is the most common complication of peritoneal dialysis. The first time this happens, a sample must be sent to the microbiology laboratory to exclude infection. Guideline 5.1.1 – PD Infectious Complications : Prevention Strategies Suggested antibiotic regimens when dialysate fluid culture is available. Initial regimens must cover both gram-positive and gram-negative organisms; the latest ISPD guidelines (www.ispd.org) give examples of appropriate antibiotics including vancomycin, cephalosporins, and aminoglycosides.10,11 Dosage regimens will depend on whether the patient is on CAPD or APD. An alternative diagnostic test is to perform scintigraphy after injection of a compound such as technetium Tc 99m–labeled diethylenetriaminepentaacetic acid (99mTc-DTPA; Fig. The dialysis fluid used in PD tends to be highly concentrated in dextrose to help move a higher amount of fluid and waste into the abdominal cavity. If the results of this testing prove negative, the patient can be reassured. Alternatively, the catheter can be repositioned at laparotomy or with the laparoscope. This will clear within one or two cycles, and the majority of the cells found will be mononuclear leukocytes. The most common reason for outflow failure is constipation, although causes of inflow failure discussed previously should also be considered. Bacteria can enter your body through your catheter as you connect or disconnect it from the bags. An infection can also develop at the site where the catheter is inserted to carry the cleansing fluid (dialysate) into and out of your abdomen. Mechanical or catheter-related problems are more likely to occur at the start or early in the treatment course, or when there is an increase made to the volume of the dialysate; infectious complications can occur at any stage during the course of treatment, whereas membrane and metabolic problems are more prominent after the patient has been on treatment for months or years. In-Center or Home Dialysis: Which Type is Right for Me. The site of the leak can be visualized on computed tomography (CT) scanning after intraperitoneal instillation of contrast material or on magnetic resonance imaging (MRI) without the use of contrast. © 2017, 2020 Fresenius Medical Care. The diagnosis of peritonitis should be suspected in any patient who develops a cloudy bag when PD fluid is drained or abdominal pain. » Articles » Peritoneal Dialysis » Complications of Peritoneal Dialysis (PD) Complications of Peritoneal Dialysis (PD) These articles will provide an overview of infectious and non-infectious complications of peritoneal dialysis. 2. We would no longer recommend the use of an endoscopic brush because of safety concerns. (vi). Post a comment. The present report summarizes the mechanical and infectious complications attributable to the devices and procedures used for chronic peritoneal dialysis (PD), comparing the type and frequency of such complications in contemporaneous groups of patients undergoing continuous ambulatory PD (CAPD) or intermittent PD (IPD). 97-2, A). 97-2, B). It is intended to replace as many functions of the failing kidneys as possible. Although PD catheters can be used as the primary approach to manage late-presenting patients or for acute kidney injury, the incidence of leaks is higher under these conditions.6. Simon J. Davies, Martin E. Wilkie. Inguinal hernia during peritoneal dialysis. On occasion, fluid may leak from the exit site or even the incision used to insert the catheter into the peritoneal cavity. (iii) Mayo Clinic. (iv) Perforation can be caused by the insertion of a too-long catheter or by the poor positioning of the catheter into the peritoneum. If this shows that the catheter is in a satisfactory position in the pelvis, an attempt to restore patency should be made with a thrombolytic agent (urokinase, 100,000 U or tissue plasminogen activator [tPA], 2 mg in 40 ml of normal saline, either instilled for at least 1 hour)5 diluted in normal saline, which can be instilled into the PD catheter for approximately 1 hour before being withdrawn. Peritonitis is a common and serious complication of peritoneal dialysis (PD). It may be necessary for the patient to stand or to perform other maneuvers to increase intra-abdominal pressure before the leak is demonstrated (Fig. There are wide variations in peritonitis rates both between and within countries. Metabolic complication of peritoneal dialysis 1. Nevertheless, PD‐related infections, including peritonitis, exit‐site infections (ESI), and tunnel infections, are important complications, resulting in significant morbidity and a 3.5–10.0% risk of death. Risk factors include ascites and peritoneal dialysis. Pericatheter leaks, which are leaks that occur around the PD catheter, are reported to affect up to 40% of PD patients. Immediately on drainage the bag may appear cloudy, but on standing the fibrin will aggregate and the fluid becomes clear. PD-associated peritonitis is the direct or major contributing cause of death in >15% of patients on PD (1, 2). APD patients are now given large loading doses in dialysis fluid with a minimum 6-hour dwell (e.g., vancomycin 30 mg/kg) and then are given additional doses every 3 to 5 days according to checked blood levels. An infection of the abdominal lining (peritonitis) is a common complication of peritoneal dialysis. Slowing the rate of fluid inflow will often reduce the symptoms, and peritonitis should be excluded and treated. Peritonitis is the inflammation of a thin layer of tissue inside the abdomen. The dialysis fluid used in PD tends to be highly concentrated in dextrose to help move a higher amount of... Hernia. (n.d.).
