Intradialytic Parenteral Nutrition (IDPN)

Nutritional Support for Malnourished Hemodialysis Patients

Pharmko's Intradialytic Parenteral Nutrition (IDPN) therapy delivers essential nutrients to patients undergoing dialysis who are struggling with malnutrition. Formulated and compounded based on each patient's clinical profile, IDPN is administered during regular dialysis sessions to improve nutritional status and support better outcomes.

Intradialytic Parenteral Nutrition (IDPN)

Intradialytic Parenteral Nutrition (IDPN)

Intradialytic Parenteral Nutrition (IDPN) is a form of supplemental nutrition delivered intravenously during hemodialysis sessions to treat malnourished dialysis patients who cannot meet their nutritional needs through oral intake or supplements alone.

How IDPN Works:

IDPN solutions containing amino acids, glucose, and lipids are infused directly into the venous drip chamber of the hemodialysis machine during the patient's regular dialysis treatment. This approach provides:

No Additional IV Access Required

Uses the existing dialysis circuit—no separate line needed

Convenience for Patients

Administered 3x/week during regularly scheduled dialysis sessions

Supplemental Nutrition

Typically delivers 800-1,200 calories per session

Minimal Workflow Disruption

Integrates seamlessly into dialysis center operations

Clinical Context: Malnutrition in Hemodialysis

Malnutrition affects 20-60% of hemodialysis patients and is one of the strongest predictors of mortality and morbidity in this population. Protein-energy wasting (PEW) results from:

Poor appetite and decreased oral intake

Chronic inflammation and metabolic acidosis

Protein loss during dialysis

Increased catabolism from uremia

Dietary restrictions (low potassium, low phosphorus)

IDPN is recommended when dietary counseling and oral supplements fail to improve nutritional status.

Clinical Indications: When to Consider IDPN

IDPN is appropriate for hemodialysis patients with protein-energy wasting who have not responded to first-line nutritional interventions.

Stepwise Approach to Renal Malnutrition

Clinical guidelines recommend the following progression:

1

Dietary Counseling

Renal dietitian provides individualized nutrition plan

2

Oral Nutritional Supplements (ONS)

Renal-specific oral supplements to increase protein/calorie intake

3

IDPN Therapy

When Steps 1 & 2 are insufficient or not tolerated

Clinical Criteria for IDPN

Lab & Clinical Indicators

Patients typically present with:

Serum albumin <3.5 g/dL (persistently low despite interventions)

Adequate dialysis: Kt/V ≥1.25 (hemodialysis adequacy)

Unintentional weight loss (>5% in 3 months or >10% in 6 months)

Low prealbumin or transferrin

Decreased muscle mass (mid-arm circumference, hand grip strength)

Patient Characteristics

IDPN candidates often have:

Poor oral intake despite dietary counseling

Intolerance to oral supplements (GI symptoms)

Anorexia or early satiety

Chronic inflammation (elevated CRP)

High catabolic state (infection, wounds)

Multiple comorbidities increasing metabolic demand

IDPN is recommended when dietary counseling and oral supplements fail to improve nutritional status.

Important: IDPN is not a substitute for addressing underlying causes of malnutrition (underdialysis, inflammation, acidosis). These should be optimized alongside IDPN therapy.

How Pharmko Delivers Personalized IDPN Support

From Referral to Dialysis Integration: Our Streamlined Clinical Process

1

Nutritional Assessment & Referral

Nephrologists or renal dietitians identify appropriate patients and submit detailed clinical documentation for Pharmko's review, including:

Current lab values (albumin, prealbumin, CBC, CMP)

Dialysis adequacy (Kt/V)

Documentation of failed dietary counseling/ONS trials

Weight history and nutritional assessment

2

Customized IDPN Compounding

Pharmko's clinical pharmacists prepare individualized IDPN formulations tailored to each patient's needs:

Amino acids: Typically 10% solution, providing essential and non-essential amino acids

Dextrose: 40-50% glucose for energy

Lipid emulsion: 10-20% fat for essential fatty acids and calories

Vitamins & minerals: Renal-appropriate micronutrients

Each formula is customized based on the patient's weight, lab results, dialysis prescription, and comorbidities.

3

Dialysis Integration

IDPN is delivered with a multi-function infusion pump that integrates seamlessly into dialysis workflows:

No additional IV setup: Infuses through venous drip chamber of dialysis circuit

No IV poles required: Pump clamps directly onto dialysis machine

Timed infusion: Administered over 3-4 hours during dialysis session

Minimal staff burden: Simple setup, low maintenance

Pharmko provides brief on-site training for dialysis center staff.

4

Scheduled Delivery & Supply Management

Formulations and supplies are shipped regularly to dialysis centers, timed with the patient's treatment plan:

IDPN — Who It's For

Dialysis Patients with Malnutrition

Patients receiving hemodialysis who are unable to meet their daily protein and caloric needs through oral intake alone, despite dietary counseling and oral supplement trials.

Unintentional Weight or Muscle Loss

Those experiencing progressive weight loss, muscle wasting, or fatigue related to protein-energy wasting (PEW) or chronic inflammation, with albumin persistently below 3.5 g/dL.

Poor Appetite or Low Nutritional Intake

Patients with anorexia, gastrointestinal symptoms (nausea, early satiety), or strict dietary restrictions that make it difficult to consume adequate nutrients orally.

High Metabolic Demand

Dialysis patients with increased nutritional needs due to infections, wounds, multiple comorbidities, or high catabolic states that exceed what oral intake can provide.

IDPN — Who It's For

  • What is parenteral nutrition for dialysis patients?

    Parenteral nutrition for dialysis patients refers to intravenous nutrition delivered to hemodialysis patients who cannot meet their nutritional needs through eating or oral supplements. The most common form is Intradialytic Parenteral Nutrition (IDPN), which is administered during dialysis sessions by infusing nutrients directly into the dialysis circuit.


    IDPN provides amino acids, glucose, lipids, vitamins, and minerals without requiring a separate IV line. It's recommended after dietary counseling and oral supplements have failed to improve nutritional status.

  • What is the difference between TPN and IDPN?

    TPN IDPN

    Scope Complete nutrition (100% of needs) Supplemental nutrition (partial)

    When Given Continuously or overnight at home Only during dialysis (3x/week)

    IV Access Requires central venous catheter Uses dialysis circuit (no extra line)

    Patient Type Non-functional GI tract Hemodialysis patients with malnutrition

    Calories 1,500-2,500+ per day 800-1,200 per session (3x/week)

    IDPN is for hemodialysis patients who can still eat but can't get enough nutrition orally. TPN is for patients who cannot use their digestive system at all.

  • Can you get PPN at home?

    Peripheral Parenteral Nutrition (PPN) is typically administered in hospital settings for short-term use (less than 2 weeks). While technically possible at home with appropriate training, PPN is rarely used for long-term home therapy because:


    It requires peripheral IV access, which has higher risk of phlebitis and infiltration

    Lower concentration formulas (due to peripheral vein limitations) provide fewer calories

    Frequent IV site changes are needed

    For long-term home parenteral nutrition, Total Parenteral Nutrition (TPN) via central line is preferred.


    For hemodialysis patients specifically, IDPN is the most practical option because it uses the existing dialysis access and is administered at the dialysis center during regularly scheduled treatments.

  • What are the risks of IDPN?


    IDPN is generally safe when properly monitored. Potential risks include:


    Metabolic Risks:


    Hyperglycemia: Rapid glucose infusion during dialysis can raise blood sugar, especially in diabetic patients (managed with insulin if needed)

    Electrolyte imbalances: Monitored through regular lab work and formula adjustments

    Hyperlipidemia: Elevated triglycerides from lipid infusions (less common with modern formulations)

    Catheter-Related Risks:


    IDPN uses the existing dialysis access, so there is no additional infection risk beyond standard dialysis catheter care

    Other Considerations:


    Fluid overload: IDPN formulations are designed to minimize fluid volume; dialysis prescription may be adjusted

    Refeeding syndrome: Rare in IDPN; gradual introduction of therapy reduces risk

    Importantly, IDPN does NOT appear to increase infection risk compared to standard TPN, because it uses the dialysis circuit rather than a separate central line. Clinical monitoring (monthly labs, weight tracking) minimizes metabolic risks.

For Patients and Families

What to Expect with IDPN

If your care team has mentioned IDPN, here is what it means for you. It is given during the dialysis session you already attend.

1

The conversation with your care team

Your nephrologist or dietitian identifies that your nutrition needs are not being met by diet and supplements alone, and writes the order. We handle the insurance verification and coordinate directly with your dialysis center.

2

We coordinate with your center

Your formula is compounded for you and delivered to the clinic where you receive treatment. Your dialysis staff receive everything they need in advance. There is nothing for you to carry, store, or set up.

3

Your first treatment with IDPN

Your nutrition is delivered through your existing dialysis access during the session. No additional needle, no separate line, and no added time in the chair. For most patients, the session feels the same as any other.

4

Settling into the schedule

IDPN is given at your regular treatments, so it follows the schedule you already keep. There is nothing extra to remember between sessions.

5

Tracking how you are doing

Your pharmacist reviews your lab work with your nephrologist and dietitian on an ongoing basis, and your formula is adjusted as your numbers change. You will hear about your progress rather than having to ask.

For Patients and Families

Questions Patients Ask Us

What IDPN actually changes about your treatment day, in plain language.

Will IDPN make my dialysis session longer?

No. It is delivered during the treatment time you already have scheduled.

Do I need another needle or a separate line?

No. IDPN is given through your existing dialysis access, so there is nothing new to place.

Will I feel different during or after treatment?

Most patients feel no difference during the session. Any changes you do notice are worth mentioning to your nurse or dietitian, who can pass them to us.

Do I still need to follow my renal diet?

Yes. IDPN supplements your nutrition, it does not replace what you eat. Your dietitian will keep guiding your diet alongside it.

How soon will I notice a difference?

Nutritional improvement is gradual and measured in lab work over weeks and months rather than days. Your team will track it with you.

Is there anything I need to do at home?

No. Your formula is delivered to your dialysis center and administered there. There is nothing to store or manage between sessions.

Who answers when I call?

Someone from our team, at any hour. For anything urgent or medical, call your dialysis center, your physician, or 911.

Three Afternoons a Week

The treatment day does not change

Rosa has been coming to the same chair for two years, and she knows everyone's names. Her nutrition runs through the same line as her treatment, so nothing about the afternoon changed when it started. She talks with her nurse. She goes home at the usual time.
