Objectives
To provide attendees with a summarized
review of peritoneal dialysis To highlight
key points in the clinical care of a PD patient
Catheter Placement Care of Catheter Infectious
Complication Non Infectious Complications Adequac
y Fluid Balance assessment of the PD patient.

Peritoneal Dialysis
  • Alternative to hemodialysis
  • Patient is taught to perform dialysis exchanges
    in the home setting
  • Focus is on patient autonomy and self care
    management
  • Patient must be followed by a licensed Peritoneal
    Dialysis unit Nephrologist

4
Peritoneal Membrane
  • Translucent
  • Vascular membrane
  • Two layers
  • Parietal (inner surface of abdominal wall)
  • Receives blood supply from the arteries of the
    abdominal wall
  • Visceral (covers abdominal viscera)
  • Covers the abdominal organs
  • Blood is carried by the mesenteric and celiac
    arteries
  • Most vascular layer where most of the dialysis
    occurs
  • Envelope of space between layers called
    peritoneal cavity
  • Semi-permeable-acts as a Filter
  • Kelley 2004

5
Anatomy and Physiology
  • Peritoneal Membrane
  • Semi-permeable
  • Bi-directional
  • Membrane size- 1-2 m2
  • Vascular wall, interstitium, mesothelium , and
    adjacent fluid films
  • Closed in males
  • Women- ovaries and fallopian tubes open into the
    peritoneal cavity
  • Peritoneal cavity normally contains about 100 ml
    transudate

6
Kinetics of Peritoneal Dialysis
  • Diffusion
  • Osmosis
  • Ultrafiltration
  • Drug Transport

Osmosis
  • The diffusion of pure solvent across a membrane
    in response to a concentration gradient, usually
    from a solution of lesser to one of greater
    solute concentration.

11
The Peritoneal Dialysis Process
  • Definition- intra (within) corporeal dialysis
  • Three Phases to the Exchange process
  • Drain
  • Fill
  • Dwell

12
How Does PD Work?
  • The semi-permeable peritoneal membrane lines the
    abdominal cavity and covers the abdominal
    viscera.
  • The membrane allows (via diffusion) the passage
    of toxins and electrolytes into the dialysis
    solution.
  • Ultra-filtration (removal of fluid) occurs via
    osmosis.
  • A steady state of toxin clearance and fluid
    management is achieved due to daily performance
    of dialysis.
  • K. Kelly , RN
  • NNJ Sept-Oct 2004

13
How Does PD Work?
  • Dialysis solution is infused and drained via a
    catheter that is surgically placed in the
    peritoneal cavity.
  • The action of draining and infusing dialysis
    solution is called an exchange.
  • The frequency of exchanges and volume is
    determined by the presence of residual renal
    function and the individual membrane
    characteristic.

Peritoneal Dialysis
  • Dialysis occurs during the dwell phase
  • Diffusion solutes cross from area of greater
    concentration to lesser one
  • -depends on concentration gradient
  • -enough peritoneal surface area
  • -size of fill volume
  • Ultra-filtration water removal due to osmotic
    gradient between the hyperosmolar PD fluid and
    the capillary bed
  • Kelley 2004

17
Historical Perspectives
  • Acute-Predominant use of PD prior to 1960s
  • 1966- Automated cycler
  • 1967- Tenckhoff catheter
  • 1975- CAPD
  • 1978- Polyvinyl bags and manufactured in the US
    (prior PD fluid was available in glass bottles)
  • 1980s- New catheter designs
  • 1987- PET and tidal PD -Twardowski
  • 1990s-Alternative dialysate solutions,
  • updated system designs ANNA Core
    Curriculum 5th Ed

18
Who Are the PD Patients ?
  • Choose PD as Renal Replacement Therapy
  • Hemodialysis Patient without Access
  • Failed allograft (transplanted kidney)
  • Have CHF or CVD which exempts them
  • from hemodialysis
  • Often people with the benefit of CKD education

19
  • PD Patient Selection
  • Inclusion Criteria Include
  • Patients who
  • Choose the modality
  • Want control
  • Prefer home for dialysis
  • Have residual renal function
  • CVD, CHF

  • Social support system available

20
Selection Continued
  • Exclusion Criteria
  • Patients who
  • Have abdominal aortic aneurysm AAA (size
    dependent)
  • Derm. disease of the abdominal wall
  • Morbid abdominal obesity
  • Altered mental status, poor coping styles
  • Solitary life style
  • Patient states lack of interest in modality
  • Multiple abdominal surgeries- adhesions
  • Ostomies (increase risk of infection)
  • Recurrent hernias

21
Steps to PD Catheter Access
  • Evaluation by Nephrologist for PD catheter
    placement and identified as candidate.
  • Educated about catheter placement, pre and post
    operative care routines.
  • Referred to surgeon for evaluation that includes
    determination of exit site,clinical anesthesia
    work-up, contraindications, completion of consent
    forms and scheduling of surgery.

22
Surgical EvaluationCatheter Insertion
  • Some units advocate insertion 2 to 6 weeks prior
    to dialysis to optimize healing.
  • Some units advocate insertion months in
    advance.(burying the catheter)
  • In most situations, PD access is elective

23
Surgical Evaluation
  • Abdominal wall weakness or hernia
  • Repair hernia preemptively or when symptomatic
  • Previous abdominal surgeries multiple surgeries
    increased likelihood of adhesions
  • Abdominal wall obesity

  • No need to wear a mask while performing PD
    exchanges
  • Incision site to be exposed to air during
    immediate post-op period
  • Administration of prophylactic IV antibiotics
    prior to catheter implantation to reduce the risk
    of peritonitis

Warming the Solution
  • Use warm, dry heat
  • At home- PD heating pad
  • NEVER MICROWAVE!!
  • Uneven heating of dextrose can create a
  • 1st or 2nd degree burn to peritoneum
  • Leaching of plastics into dialysate can
  • Create a chemical peritonitis
  • NEVER MICROWAVE!!

50
Patients at risk for inadequate dialysis
  • No residual renal function
  • Low membrane permeability
  • Large patients
  • Patients not doing their treatments

51
PD Equilibration TestAKA PET
  • First developed by Z. Twardowski at the
    University of Missouri
  • A four hour study that assesses membrane
    transport characteristics.
  • Assessment of membrane function allows for
    accurate prescription planning.
  • Usually completed within the first six weeks of
    initiating PD
  • Repeated per each units protocol

52
PD Equilibration Test continued
  • What does this tell us?
  • The results indicate the following transport
    states
  • High
  • High-average
  • Low-average
  • Low

53
Transporter Waste removal Water removal Best type of PD
High or Fast Fast Poor Frequent exchanges, short dwells APD
Average Okay Okay CAPD or APD
Low Slow Good CAPD, 5 evenly spaced exchanges 1 exchange at night using a small machine.

54
KT/V Test
  • What is measured?
  • 24 hour collection of dialysate and urine
  • Serum values of BUN and Creatinine
  • Frequency of test is determined by each units
    protocols and interpretation of K/DOQI
    guidelines. (Unit specific, usually quarterly or
    bi-annually)

55
KT/V Test continued
  • What does it tell us?
  • The adequacy of the current prescription
  • Need for adjustments to insure appropriate
    dialysis prescription

56
Exit Site Care
  • Healthy exit site surrounding skin natural,
    darkened, or light Pink no drainage or crusting
    visible sinus is dry
  • Goal prevent exit site infection and identify
    problems early
  • ES Care daily or 3-4 times weekly may be in
    conjunction with showering

57
Infection Prevention
  • Exit Site Care
  • No dressing needed for established catheter exit
    site (unit or pt specific)
  • Keep catheter secured to abdomen with 2 inch tape
  • Daily showers with liquid soap
  • Mupirocin (Bactroban ) or Gentamycin Cream at
    exit site of known staph. Carrier
  • Inpatients-dry dressing to protect site, cleaned
    with soap and water, No occlusive membrane
    dressings (Tegaderm )
  • A healed and non-infected exit site is crucial to
    longevity on Peritoneal Dialysis

58
Question
  • Following peritoneal dialysis catheter
    implantation, a patient is instructed that
  • The exit will always be tender
  • Baggy clothes will have to be worn
  • The catheter will need to be changed monthly
  • Well-healed healthy exit-sites make swimming
    possible
  • Core curriculum for Nephrology Nursing, 5th
    Edition. American Nephrology Nurses Association

59
Infectious Complications
60
Exit Site Infection
  • Teach patient to identify and report immediately
    to the PD Unit
  • Redness, tenderness, edema, presence of exudate
    either at exit site or insertion site
  • Treatment
  • Culture exudate if possible
  • Specific antibiotic protocol
  • Oral or IV/IP antibiotics depending on extent of
    infection
  • Saline soaks/dressing changes for care of local
    cellulitis (unit/Nephrologist specific)

61
Exit Site Infection
  • S S redness, swelling, tenderness or pain and
    purulent drainage
  • Risk Factors poor catheter healing, sutures at
    the exit site, trauma to the exit site, cuff
    extrusion and improper catheter care
  • Diagnosis Observation and culture
  • Treatment Antibiotics, IP,PO, or IV
  • vigilant daily exit site care

62
Exit Site Infection
  • A chronic exit site infection can produce a
    systemic inflammatory response.
  • Inflammation can lead to poor nutrition,
    inadequate dialysis and possible antibiotic
    resistance. Vital role of Dietitian
  • Chronic exit site infections may result in
    peritonitis.
  • Multiple infections can lead to removal and
    replacement of catheter.
  • Consistent assessment and documentation is needed
    to appropriately track infections.

63
Responsible Organisms
  • Staphylococcus Aureus
  • Pseudomonas species
  • Other Gram positive species
  • Serratia species
  • Other gram-negative organisms
  • Fungi

64
Tunnel Infection
  • S S
  • erythema over the tunnel
  • pain and tenderness
  • drainage from exit site no other signs of an
    infection
  • Risk factors
  • exit-site infection
  • exit site trauma
  • leak
  • external cuff extrusion
  • Treatment- antibiotic therapy to prevent need
    for catheter removal

65
Prevention of Peritonitis
  • Careful individualized patient training
  • Adequate daily hygiene
  • Meticulous hand washing
  • On going retraining

66
Prevention of Peritonitis
  • Basics of Aseptic Technique 5 min. hand scrub,
    face masks during exchanges, warming of PD bags
    using dry heat, aseptic technique for adding
    medicines
  • Aseptic technique when making critical
    connections to solution containers and the
    patients transfer set
  • Masks reduce the risk of contamination with
    nasopharyngeal organisms

67
Peritonitis
  • Inflammation of the peritoneal cavity
  • Defined as the presence of WBC in the effluent
    numbering 100 or greater 50 polys (neutrophil)
    or segs
  • Effluent appears cloudy and milky.
  • Patient may have fever, chills, abdominal pain,
    nausea, vomiting and diarrhea.
  • Some present initially with cloudy fluid as the
    first sign and no symptoms.
  • Patient must be taught to contact their PD Nurse
    or Nephrologist immediately for cloudy effluent.

68
Peritonitis
  • Portals of Entry
  • Transluminal- technique failure, contamination
  • Periluminal- incomplete healing ,leaking
  • Hematogenous- bacteremia
  • Transmural- through the bowel wall
  • ANNA Core Curriculum

69
Peritonitis Presentation
  • S S fever, abdominal pain, N V, diarrhea,
    and cloudy effluent
  • Incubation 24-48 hours if within 6 hours
    suspect an enteric source
  • Kinetic effects increased solute removal and
    protein loss increased glucose absorption
    leading to a decreased osmotic gradient and
    decreased ultrafiltration

70
Diagnosis of Peritonitis
  • Effective culture techniques
  • Minimum sample volume of 50-100 ml. Large samples
    reduce false negative results
  • Dialysate must be mixed well by inverting bag
    several times before sampling
  • Sample port is disinfected before sampling
  • Sample is obtained using aseptic technique

71
Question
  • A PD effluent cell count differential can
    determine if peritonitis is present when there is
    an elevation in ?
  • a. eosinophils
  • b. neutrophils
  • c. lymphocytes
  • d. granulocytes
  • Core curriculum for Nephrology Nursing, 5th
    Edition. American Nephrology Nurses Association

72
Peritonitis
  • Treatment protocols
  • Patient may be treated in PD unit or Emergency
    Room depending on severity of symptoms and
    availability of resources.
  • Effluent is sent for cell count, CS and gram
    stain
  • Fungal cultures should be included if patient is
    immunosuppressed or had had frequent infections
    requiring antibiotics
  • PD Unit should have specific antibiotic protocols
    for gram positive and gram negative coverage.

73
Peritonitis
  • Organisms
  • Gram positive-
  • Staphylococcus epidermidis
  • Staphylococcus aureus
  • Streptococcus species
  • Enterococcus
  • Gram Negative-
  • Pseudomonas
  • Klebsiella
  • Escherichia coli
  • Enterobacter
  • Fungal organisms

74
Question
  • Catheter removal is recommended when the patient
    has peritonitis associated by which of the
    following organisms?
  • Staph aureus
  • Fungal
  • Staph epi
  • Pseudomonas
  • Core curriculum for Nephrology Nursing, 5th
    Edition. American Nephrology Nurses Association

75
Non Infectious Complications
76
Non Infectious Complications
  • Pericatheter and Subcutaneous Leaks
  • Peritoneal Catheter Obstruction most commonly
    early, yet can occur at any time.
  • Hernia significant abdominal wall hernias
    should be surgically repaired prior to initiation
    of PD. Enlargement may occur due to increased
    abdominal wall pressure.

77
Non Infectious Complications
  • Pneumoperitoneum (Shoulder Pain) usually
    resulting from air infusion
  • Hemoperitoneum blood loss into the peritoneal
    cavity. A few drops of blood will produce
    grossly bloody effluent. Most common in women in
    menses. Any bleeding needs to be monitored.
  • Hydrothorax secondary to a pleuroperitoneal
    communication.

78
PD Affects Drug Transport By
  • Systemic drug removal via effluent
  • Drugs can be administered IP
  • Dose related to Urine output and mechanism for
    elimination of drug

79
Non Infectious Complications
  • Catheter Adapter Disconnect or Fracture of
    Peritoneal Catheter. Stop Dialysis, obtain
    culture, replace or repair, prophylactic
    antibiotics pending culture results

80
Membrane changes
  • Sclerosing, Encapsulating Peritonitis serious,
    yet rare, not exclusive to PD
  • A thick fibrous layer of tissue encapsulates the
    bowel
  • Membrane becomes thick and opaque
  • Onset gradual or rapid
  • Presentation
  • Decreased ultrafiltration and solute clearances
  • Recurrent abdominal pain
  • Intermittent nausea and vomiting
  • Partial and/or complete bowel obstruction
  • Intervention emergency laparotomy

81
Clinical Management Issues for the PD Patient
  • Catheter insertion and Healing of exit site
  • Prevention of infection
  • Blood pressure control Fluid management
  • Nutrition evaluation and interventions
  • Systems assessment
  • Medication evaluation
  • Anemia,Ca/Phos./PTH management
  • PET and initial Kt/V
  • Coping with stress of chronic illness
  • Transplantation

82
Current Issues in Peritoneal Dialysis
  • Revision of K/DOQI
  • Co-morbidities
  • Role of sodium
  • Volume Control
  • Blood pressure control
  • Utilization of Icodextrin
  • Role of inflammation
  • Integrated dialysis care
  • Improving nephrology fellow education
  • CKD education for patients and families
  • ADEMEX study-adequacy
  • European APD Outcome Study (2003)
  • Underutilization of Peritoneal Dialysis

83
Final Note
  • The success of PD can be attributed to the
    combined efforts of researchers, individuals on
    PD, and healthcare professionals who, in
    collaboration with the industrial community, have
    realized the potential benefits of the treatment.
    Despite a slow start in comparison to HD, PD has
    evolved into a modality that equals HD in long
    term outcomes.
