Peritoneal dialysis and its impact on intra-abdominal pressure and respiratory mechanics in the critically ill patient: Can PD take the pressure?

Peritoneal dialysis (PD) was historically the initial kidney replacement modality of choice for patients admitted to the intensive care unit, and there are several advantages to maintaining critically ill PD patients on their usual dialysis therapy. However, in this patient population, there are two contentious questions: how are the respiratory dynamics of mechanical ventilation impacted by the presence of dialysate within the abdomen, and what can be done to mitigate these potential effects? This review discusses the theoretical impact of PD on intra-abdominal pressure (IAP) and evidence for the effect of IAP on respiratory mechanics in mechanically ventilated PD patients.

The effect of implementing a dialysis start unit on modality decision among patients with unplanned start kidney replacement therapy.

Introduction: Many individuals start dialysis in an acute setting with suboptimal pre-dialysis education. These individuals are often treated with central venous catheter insertion and initiation of in-center hemodialysis and only a minority will transfer to a home-based therapy. The dialysis start unit is a program performing in-center hemodialysis in a separate space while providing support and education on chronic kidney disease and treatment options in the initial weeks of kidney replacement therapy.

Integrated home dialysis model: facilitating home-to-home transition.

Peritoneal dialysis (PD) and home hemodialysis (HHD) are the two home dialysis modalities offered to patients. They promote patient autonomy, enhance independence, and are generally associated with better quality of life compared to facility hemodialysis. PD offers some advantages (enhanced flexibility, ability to travel, preservation of residual kidney function, and vascular access sites) but few patients remain on PD indefinitely due to peritonitis and other complications.

Unusual and complicated peritonitis: Your questions answered.

Effective treatment of infections is a growing challenge owing to antimicrobial resistance. Peritoneal dialysis (PD) patients experience more frequent hospitalisations than the general population and have greater exposure to antibiotics, making them particularly vulnerable to this threat. Over the last decade, we have noted a surge in cases of complicated peritoneal dialysis-associated peritonitis (PD peritonitis) caused by antimicrobial-resistant organisms, including extended-spectrum beta-lactamase (ESBL), AmpC beta-lactamase-producing Enterobacterales, and fungi.

The Removal of Uremic Solutes by Peritoneal Dialysis.

Peritoneal dialysis (PD) is now commonly prescribed to achieve target clearances for urea or creatinine. The International Society for Peritoneal Dialysis has proposed however that such targets should no longer be imposed. The Society's new guidelines suggest rather that the PD prescription should be adjusted to achieve well-being in individual patients.

Peritoneal Dialysis Prescription and Adequacy in Clinical Practice: Core Curriculum 2023.

As the global prevalence of peritoneal dialysis (PD) continues to grow, practitioners must be equipped with prescribing strategies that focus on the needs and preferences of patients. PD is an effective form of kidney replacement therapy that offers numerous benefits to patients, including more flexibility in schedules compared with in-center hemodialysis (HD). Additional benefits of PD include salt and water removal without significant changes in patient hemodynamics.

Care of the hospitalised patient receiving peritoneal dialysis: Your questions answered.

Peritoneal dialysis (PD) patients have higher hospitalisation rates than the general population. The hospitalisations are not always related to dialysis issues, and physicians with little or no experience with PD may be responsible for the care of these hospitalised patients. Furthermore, the hospital may not be familiar with or equipped to manage these patients.

Anxiety and psychosocial impact during coronavirus disease 2019 in home dialysis patients.

The severe acute respiratory syndrome coronavirus (SARS-Cov-2) resulting in the coronavirus disease 2019 (COVID-19) is documented to have a negative psychosocial impact on patients. Home dialysis patients may be at risk of additional isolating factors affecting their mental health. The aim of this study is to describe levels of anxiety and quality of life during the COVID-19 pandemic among home dialysis patients.

Incremental peritoneal dialysis in incident end-stage kidney disease patients.

Background: This retrospective cohort study investigated the characteristics and outcomes of the end-stage kidney disease (ESKD) patients treated with incremental peritoneal dialysis (PD) at a large academic centre.

Methods: ESKD patients initiating PD with a dialysate volume ≤6 L/day were analysed.

Results: One hundred and seventy-five patients were included and were followed up for 352.

A Comparison of Hemodialysis and Peritoneal Dialysis in Patients with Cardiovascular Disease.

The high prevalence of cardiovascular disease is caused by the traditional cardiovascular risk factors common among end-stage renal disease patients, and nontraditional risk factors attributed to underlying kidney disease, including chronic inflammation, anemia, bone mineral disease, and the dialysis procedure itself. Individualization of the treatment of cardiovascular disease in end-stage renal disease that could impact the underlying mechanisms of the cardiovascular diseases is important to improve outcomes. This article reviews and compares hemodialysis and peritoneal dialysis in association with different cardiovascular diseases affecting dialysis patients, including hypertension, coronary artery disease, myocardial stunning, cardiac arrhythmias, heart failure, and the cardiorenal syndrome.

Home-to-home dialysis transition: A 24-year single-centre experience.

Home dialysis (peritoneal dialysis (PD) and home haemodialysis (HHD)) are ideal options for kidney replacement therapy (KRT). Occasionally, because of technique failure, patients are required to transition out of home dialysis, and the most common option tends to be to in-centre HD. There are few published studies on home-to-home transition (PD to HHD or HHD to PD) and dynamics during the transition period.

The use of virtual physician mentoring to enhance home dialysis knowledge and uptake.

Home dialysis therapies are flexible kidney replacement strategies with documented clinical benefits. While the incidence of end-stage kidney disease continues to increase globally, the use of home dialysis remains low in most developed countries. Multiple barriers to providing home dialysis have been noted in the published literature.

A Single-Center Retrospective Study on the Initiation of Peritoneal Dialysis in Patients With Cardiorenal Syndrome and Subsequent Hospitalizations.

Background: Inotropic dependence and diuretic resistance in patients with cardiorenal syndrome (CRS) lead to frequent hospitalizations and are associated with high mortality. Starting peritoneal dialysis (PD) acutely (within 2 weeks of a heart failure hospitalization) offers effective volume removal without hemodynamic compromise in this population. There is little data on this approach in the North American literature.

Home Hemodialysis and Peritoneal Dialysis Patient and Technique Survival in Canada.

Introduction: As interest for home dialysis is growing, knowledge of comparative clinical outcomes between peritoneal dialysis (PD) and home hemodialysis (HHD) would help to better inform shared decision making with patients and caregivers during modality discussion. This study aimed to assess differences in risk of mortality and technique failure in an incident home dialysis cohort and, specifically, to assess change in this association through eras.

Methods: All adults patients initiating PD or HHD, in Canada (excluding Quebec), within 365 days after kidney replacement therapy (KRT) initiation between 2000 and 2013 were included (administrative censoring 31 December 2014).

Utility of Abdominal Imaging in Peritoneal Dialysis Patients Presenting With Peritonitis.

Background: Peritonitis remains a major complication in peritoneal dialysis (PD). Abdominal imaging is often performed in the setting of peritonitis to evaluate for concomitant intra-abdominal processes. However, the usefulness of this procedure is unknown.

Peritoneal Dialysis-Associated Peritonitis: Suggestions for Management and Mistakes to Avoid.

Peritonitis is a common complication of peritoneal dialysis that is associated with substantial morbidity and mortality. Peritonitis increases treatment costs and hospitalization events and is the most common reason for transfer to hemodialysis. Although there is much focus on preventing peritoneal dialysis-associated peritonitis, equally as important is appropriate management to minimize the morbidity of a peritonitis episode when it has occurred.

Predictors of Care Gaps in Home Dialysis: The Home Dialysis Virtual Ward Study.

Background: Home dialysis patients may be at an increased risk of adverse events after transitional states. The home dialysis virtual ward (HDVW) trial was conducted in Canadian dialysis centers and aimed to evaluate potential care gaps and patient satisfaction during the HDVW.

Methods: The HDVW was a multicenter single-arm trial including peritoneal dialysis and home hemodialysis patients after 4 different events (hospital discharge, medical procedure, antibiotics, completion of training).

Defining the role of peritoneal dialysis in management of congestive heart failure.

: Congestion is an integral component of heart failure (HF) pathophysiology and portends an adverse impact on outcome. Peritoneal dialysis (PD) is a home-based therapeutic modality that has been used in the setting of refractory congestive HF to help optimize volume status. Not only does PD allow for customized sodium and water removal, but it also provides the opportunity for the patients to fully benefit from guideline-directed medical therapy for HF that could have otherwise been challenging to use.
