What is Hemodialysis?

Hemodialysis is a procedure that filters waste products and excess fluid from the blood using an external dialysis machine and a dialyser. Blood is diverted from the body, cleaned, and returned through an access point.

Clinically, hemodialysis is typically performed in a hospital, dialysis center, or at home with trained staff. It commonly requires 3 sessions per week and a vascular access such as a fistula or graft, with ongoing monitoring; insurance coverage, including ManipalCigna Health Insurance, may apply.

Advantages of Hemodialysis

• Strong removal of wastes and fluids per session
• Widely available at dialysis centers
• Proven, well-established modality

Disadvantages of Hemodialysis

• Time-consuming travel to centers
• Frequent hospital visits can disrupt life
• Fluid and dietary restrictions still apply
• Vascular access risks like infection or clotting
• Access site complications may require procedures
• Hypotension during sessions can occur
• Anticoagulation risks include bleeding

• Dependence on water quality and electricity at center
• Possible fatigue after sessions
• Transportation costs and logistics
• Limited flexibility for people living far from centers
• Diet adjustment is ongoing and challenging
• Time away from work or school
• Potential for scar tissue around access
• Need for regular monitoring and labs
• Psychological burden of chronic treatment
• Infections at access sites require care
• Access problems may lead to hospitalizations

What is Peritoneal Dialysis?

Peritoneal dialysis uses the lining of the abdomen as a natural filter. Dialysate fluid is infused into the peritoneal cavity through a catheter, allowing diffusion of waste products and excess fluid, then drained after a dwell period.

Clinically, peritoneal dialysis is often performed at home, offering more independence and schedule flexibility. It requires diligent aseptic technique, daily exchanges, and access to a clean environment to minimize infection risk and ensure effective filtration.

Advantages of Peritoneal Dialysis

• Greater independence and flexibility in routine
• Dialysis can be performed at home
• Often fewer hospital visits
• Continuous toxin clearance can mimic natural kidney function
• Can be scheduled around work and family
• No need for frequent center visits
• No systemic anticoagulation during treatment
• Preserves residual kidney function in some cases
• Better control of daily life activities
• Can be performed while sleeping
• Less travel-related burden
• Fewer vascular access problems
• Potentially lower transportation costs
• Can start soon after catheter placement
• Suitable for patients who prefer home therapy
• Can adapt to intermittent or continuous schedules
• Reduced exposure to hospital-acquired infections
• Lower center workload, with home-based care
• Easier to plan around personal commitments
• Caregiver involvement can be structured

Disadvantages of Peritoneal Dialysis

• Risk of peritonitis with PD
• Catheter-related infections or leaks
• Requires daily maintenance and exchanges
• Dependence on clean home environment
• Storage and handling of dialysate fluids
• Adherence to routine is critical
• Not suitable for some abdominal conditions or surgeries
• Membrane changes can reduce effectiveness over time
• Weight gain with dialysate and glucose exposure
• Sleep disturbances with nocturnal PD in some cases
• Caregiver strain for home PD
• Initial setup costs for home equipment
• Limited suitability in places with unstable utilities
• Potential for hernia or catheter complications
• Difficult in patients with obesity
• Need for reliable supply chain for dialysate
• Monitoring and labs may require remote or center access
• Potential for chemical irritation from solutions
• Training sufficient for safe self-care can be demanding
• Not all insurers cover all PD supplies under policy terms
