Description
“Complications of Peritoneal Dialysis: Prevention and Management” focuses on recognizing, addressing, and minimizing the common and serious challenges associated with peritoneal dialysis therapy. The session covers infectious complications such as peritonitis and exit-site infections, as well as mechanical issues including catheter problems and dialysate leaks. Participants will learn evidence-based strategies for early diagnosis, prompt intervention, and long-term prevention. Practical tips for patient education, technique improvement, and maintaining optimal dialysis outcomes will be emphasized. This session aims to equip healthcare professionals with the knowledge needed to enhance patient safety and treatment success.
Summary Listen
- Peritoneal dialysis (PD) is a home-based dialysis option using a catheter inserted into the peritoneum to facilitate fluid exchange via PD bags. This process utilizes the peritoneal membrane as a dialyzing surface, removing waste products and excess fluid. PD complications are classified as mechanical/catheter-related, pressure-related, metabolic/membrane dysfunction, encapsulating peritoneal sclerosis (EPS), and miscellaneous systemic issues.
- Mechanical complications, such as catheter malfunction, often present early and are potentially reversible. Catheter migration, typically due to improper surgical placement, can lead to outflow issues. Constipation can exacerbate these problems. Management involves laxatives, ambulation, fluoroscopic repositioning, or surgical correction to ensure the catheter tip resides in the pelvic area. Drainage failure can also stem from clots within the catheter or omental wrapping, necessitating clot aspiration, heparin use, or laparoscopic omentectomy.
- Pressure-related complications encompass dialysate leaks, hernias, scrotal/vaginal swelling, and pleuroperitoneal communication. Dialysate leaks can be early, resulting from incomplete healing of the exit site, or late, often associated with hernias. Early leaks require rest and low-volume PD, while late leaks may necessitate surgical repair. Hernias, common due to increased intra-abdominal pressure, can be managed with low-volume PD in a supine position.
- Pleuroperitoneal leaks, a serious complication, can manifest as shortness of breath due to fluid movement into the pleural cavity. Diagnosis involves clinical examination, chest X-ray, and dye instillation. Treatment requires immediate PD cessation and may involve pleurodesis or VATS to repair diaphragmatic defects. Abnormal effluent, indicated by color changes, can point to non-infectious causes like eosinophilia, lymphocytosis, or hemoperitoneum.
- Ultrafiltration failure occurs when fluid removal becomes inadequate despite using high dextrose concentrations. This stems from peritoneal membrane changes and requires optimizing dwell time, glucose concentration, or using icodextrin solutions. Refractory cases necessitate switching to hemodialysis. Metabolic complications include hyperglycemia and hypokalemia. EPS is a rare but severe complication characterized by peritoneal membrane sclerosis and obstruction, requiring surgical intervention.
- Gastrointestinal complications, like reflux and early satiety, can occur due to increased intra-abdominal pressure. Management involves initiating PD with low volumes and gradually increasing them over time. APD, done at night, can help with satiety issues. General preventative measures include proper catheter placement, secure fixation, elective starts with low volumes, avoidance of heavy lifting, and a bowel regimen. PD should be continued where possible, unless certain conditions make it unsustainable.
