Disclaimer: This document was prepared by the Scottish Nutrition Nurses Group and was up to date at the time of printing. It is the responsibility of the end user to ensure care when implementing.
Guidelines and Policies for central catheter managementStaff caring for the patient on HPN should have access to guidelines and policies to prevent
complications occurring with the central catheter. Evidence-based guidelines for preventing hospital-
acquired infections associated with the use of central venous access devices have been published by
(Pratt RJ et al 2007, O’Grady et al 2002).

Venous Access for Home Parenteral Nutrition
Definition
An intravascular catheter is defined as a ‘tubular device, single or multi lumen, designed to be partially or
totally inserted or implanted into the cardiovascular system for diagnostic and /or therapeutic purposes’.
Central venous access
Central catheters are used when permanent access is required for parenteral nutrition (PN). The routes
most commonly used for venous access are the subclavian vein or internal jugular vein. There is a vast
array of catheters available for the administration of PN.
The most frequently used catheters are:
External cuffed tunneled catheters: i.e. Broviac, Hickman
External tunneled catheter: i.e. Vygon Nutricath
Subcutaneous ports
Peripheral inserted central catheters
Single versus multi lumen catheters
Multi lumen central catheters can be used for a combination of HPN and other treatments such as,
chemotherapy or antibiotic therapy. It has previously been suggested that multi lumen catheters increase
the risk of catheter-related sepsis and should not be used for the administration of PN. Many authors
have refuted this. They report that there is no statistical difference in catheter-related sepsis, between
the uses of single or triple lumen catheters.
Unless there is a particular need for a multi lumen catheter, a single lumen catheter is generally
preferred for the patient on home parenteral nutrition. The workload associated with its use is less and is
generally preferred by the patient.
The choice of catheter is dependent on venous access available, duration of therapy and most
importantly patient preference. Table 1 lists the factors that should be taken into consideration when
determining the most suitable catheter for the patient.

Table 1 – Factors in choosing a catheter for HPN
Short or long term use
Catheter material: i.e. silicone or Polyurethane
Multi or single lumen catheter, Cuffed or non-cuffed catheter
Implantable or external device
Patient preference/ body image, patients ability to care for central catheter
Ease of sterile dressing applications
Cost
Gauge of catheter and vein diameter. The narrowest catheter in the largest vein will provide better flow and reduce vein damage
Method of catheter removal
As the availability of these intravascular devices increases, so must the health professional's knowledge
base. It is essential that the nutrition team have knowledge of which device may be best suited for each
patient and be aware of which catheter has the fewest known complications.
There is a place for each catheter in the care of the patient with HPN; the choice will often be determined
by the patient and their needs. Table 2 lists the common advantages and disadvantages of each
catheter.
Catheter insertion
The central catheter should be inserted in an aseptic environment under the supervision of an
experienced clinician. There is strong evidence that using ultrasound guidance is a more effective
method of insertion (British Committee for Standards in Haematology, 2006). Potential complications
associated with the insertion of the catheter include:
Pneumothorax Venous air embolism
Arterial puncture Catheter misplacement
Cardiac tamponade Cardiac arrhythmias

Table 2 Advantages and disadvantages of the commonly used catheters
Catheter type Advantages Disadvantages
External cuffed tunneled catheters: i.e. Broviac, Hickman
No external sutures requiredExternal portion of the catheter can be repaired without replacementNo discomfort when connecting PNCan be sterilised by antibiotic lock during periods of catheter sepsisCan remain in situ for several years
Requires an aseptic dressingProblems re body imageRequires surgical placement and removal
External tunneled catheter: i.e. Vygon Nutricath™
No discomfort when connecting PNCan be sterilised by antibiotic lock during periods of catheter sepsis
Requires an aseptic dressingProblems re body imageMay require sutures to anchor catheter to skin
Subcutaneous ports Freedom from dressingsReduces risk of exit site infectionsImproved patient toleranceAllows the patient to bathe and swim
Local discomfort and pain during use, possible skin ulcerationRequires operative placementCannot be sterilised by antibiotic lock if sepsis occursCatheter replacement required more frequently than external catheter
Peripheral inserted central catheters
Ease of insertionEase of removalReduced insertion associated complications
Requires suturingOcclusion /kinking problemsIncreased risk of catheter tip misplacement
A catheter placed in an optimal position, taking into consideration if patient is left or right handed, will
reduce potential complications. When inserting the catheter the clinician will consider the following
points:
The catheter tip should lie above the junction of the superior vena cava and right atrium
If a Dacron cuffed catheter is used, the cuff should be placed in the mid point of the tunnel away from
the exit site
A Chest X-Ray should be carried out to check the position of the catheter before PN is commenced
(unless inserted in radiology).

Central venous access device care
Central venous access device-related infections account for 90% of nosocomial (hospital acquired)
bloodstream infections. Despite the profuse availability of evidence, there continues to be a significant
diversity in practice of health care professionals. It has been well documented that experienced staff and
educational programs can have a significant impact on the rate of catheter related problems. For this
reason it is essential that all staff caring for a patient with a central venous access device have access to
educational material and researched based protocols and procedures.
Hand washing
It is well documented that the most common cause of the spread of nosocomial infection is via the hands
of health care workers because of their inability to correctly wash their hands. Therefore, the first crucial
step in the reduction of catheter related sepsis is knowledge of the principles of hand washing and the
use of gloves. Any procedure connected with an intravenous catheter requires the health care worker to
wash with an antibacterial handwash. The purpose of a handwash is to remove dirt and to reduce the
load of bacteria on the skin of the hands. Washing with soap and water will remove the transient
bacterial flora, and washing with a cleansing agent will reduce the resident bacteria on hands. It should
be noted however, that resident bacteria will not be totally eliminated by hand washing.
There are several types of handwash available for use, each have different properties and advantages.
Choosing the appropriate agent will depend on several factors. APIC guidelines for hand washing and
hand cleansing in heath care settings (1995) describe three stages:
Characteristics that are desired (e.g. rapid destruction in flora, spectrum of activity)
Evidence of safety and efficacy
Staff acceptance
The practice of hand washing
The use of any handwash solution will prove to be ineffective if staff do not employ the correct hand
washing technique. Various studies have concluded that health care workers do not wash their hands
effectively, leaving many parts of the hands not exposed to soap, water or handwash. In practice the
most commonly missed areas are the fingertips, the thumb and the inside of the fingers.
The use of an alcohol hand rub/gel is known to be effective. It is a powerful cleansing agent that can be
applied quickly to hands that are not soiled. It will rapidly kill transient bacteria and a proportion of the
resident bacteria.
Scottish HPN Managed Clinical Network ProtocolsRevised August 2010 - For revision August 2013

The use of gloves
It is important that gloves are used in conjunction with hand washing and not in place of hand washing.
Many health care workers believe that gloves protect staff and patients from cross contamination, but in
reality this is not the case as hands can become easily contaminated under gloves when they are
unwittingly punctured or when they are removed. The lack of evidence regarding the benefits of using
sterile gloves has resulted in many teams developing procedures based on using a non-touch technique.
The care of the hub/the use of connection devicesSeveral studies have implicated contamination of the hub as the major source of catheter related sepsis
in catheters that remain in situ for more than two weeks. It is recommended that limited manipulations to
the catheter should occur, as each junction break brings additional risk of infection.
To reduce the risk of hub contamination:
Meticulous care must be taken when a break in the closed system occurs. Strict adherence to
policies and effective hand washing techniques are essential
If a multi lumen catheter is used, one lumen should be designated for the PN
A single lumen catheter should not be used for the administration of drug therapy or additional
intravenous fluids
The catheter should not be used for routine blood samples
Scottish HPN Managed Clinical Network ProtocolsRevised August 2010 - For revision August 2013

The use of closed luer lock connection devices with a membrane allows access to the catheter whilst
maintaining a closed system. (E.g. Bionector, Interlink, Smartsite).
The perceived benefit of this system is:
Reduction in nursing workload
Reduction in use of sterile equipment / reduce costs
Reduction in needle stick injuries
Reduction in catheter related sepsis
Reduction in air embolus
Connection devices are now widely used in clinical practice. Some health professionals are concerned
about the potential risk of contamination. Several studies have addressed this issue and conclude that
there is no evidence that their use is associated with increased risk of catheter related infection. When
using connection devices the greatest risk leading to contamination is an inability to disinfect the device
before puncture. The most effective method of disinfection is the use of a combination of antiseptic spray
and alcohol.
Anecdotal evidence suggests that using the closed system is much less cumbersome for nursing staff
and patients to use and thus compliance with procedures may be better. However, the use of the closed
systems does not diminish the need for careful catheter techniques, and the adherence of staff to
guidelines and educational programmes, remains the most vital aspect in the rate of catheter related
sepsis.
Changing connection devices
Routine connection device changes should occur as per manufacturer’s instructions. It will be necessary
to change earlier if blood products or lipid deposits are present, if damaged, contaminated or after
routine flushing.
Care of central venous access device exit site – Principles of careThe exit site forms an artificial break in the skin and is, with the tunnel, a potential source of infection. An
aseptic technique is therefore required when cleaning the exit site and changing the dressing. It has
been suggested that the use of an aseptic technique by a specially trained person has more effect on
reducing the rate of catheter related infection than the type of cleansing agent or dressing used.
There are several issues that require to be addressed when developing guidelines for care of the
catheter exit site. These are firstly the most appropriate cleansing solution secondly the most appropriate
dressing and thirdly how often the dressing should be changed.
Scottish HPN Managed Clinical Network ProtocolsRevised August 2010 - For revision August 2013

Cleansing Solutions
An alcoholic chlorhexidine gluconate solution (preferably gluconate in 70% isopropyl alcohol) should be
used to clean the catheter insertion site during dressing changes, and allowed to air dry (Pratt et al,
2007). An aqueous solution of chlorhexidine gluconate should be used if the manufacturer’s
recommendations prohibit the use of alcohol with their product (Pratt et al, 2007).
1. Dressings
The optimal dressing for the exit site remains controversial. The type of dressings frequently used
includes sterile gauze dressing and transparent occlusive dressing. Several studies have reported an
increased rate of infection associated with the use of transparent dressings. This is believed to be due to
an increase of moisture at the exit site. However, other studies have found no statistical difference in
rates of infection between transparent or gauze dressing. (It has been suggested than transparent
occlusive dressings are preferred by the patient, are cost effective, and can result in a reduction of
nursing time. The need for any type of dressing has also been studied. The frequency of exit site
infection is no greater when there was no dressing applied.
Dry dressing - Mepore™, Primapore™
Limitations associated with the use of this dressing, is the inability to visualise the exit site, and the need
for frequent manipulation of the dressing if the site needs to be checked. Their inability to provide a
bacterial and water barrier allows for the potential contamination from secretions or external moisture.
Transparent/ occlusive dressing – IV 3000™, Tegaderm™
The advantage of a transparent dressing is the ability to secure the catheter, to permit continuous
inspection of the site, to adhere well to dry skin, and to provide protection against external moisture
sources.
2. Dressing Changes
A Cochrane Review of gauze and tape versus transparent polyurethane dressings for CVAD concluded
that there was no evidence demonstrating any difference in the incidence of CR-related infections
between any of the dressing types compared in this review. Preferably, a sterile, transparent, semi-
permeable polyurethane dressing should be used to cover the catheter site. Transparent dressings
Scottish HPN Managed Clinical Network ProtocolsRevised August 2010 - For revision August 2013

should be changed every 7 days or sooner if they are no longer intact or moisture collects under the
dressing. (Pratt et al, 2007)
Recommendations for care of the exit site
1. The procedure should be carried out by an experienced member of staff
2. Cleansing solution is recommended to cleanse the exit site
3. The exit site should be cleansed with swabs working away from the catheter site, outward and
downward. The movement of the catheter should be limited to prevent unnecessary trauma.
4. Assessment of the exit site at dressing changes is important to detect any sign of redness,
inflammation or exudates. Any changes should be documented.
5. If the area is encrusted or appears infected take a culture swab from the exit site
6. Do not use occlusive dressing if exit site is moist or leaking
7. Occlusive dressing should be changed weekly or before if there is drainage from the exit site or the
dressing has becomes non-occlusive
8. The need for a gauze dressing should be assessed daily and changed when inspection of the
insertion site is necessary or when the dressing becomes damp, loosened or soiled. A gauze
dressing should be replaced by a transparent dressing as soon as possible. (Pratt et al, 2007)
9. Dressings used on tunneled or implanted catheter insertion sites should be replaced every 7 days
until the insertion site has healed, unless there is an indication to change them sooner. (Pratt et al,
2007).

Complications
The network has prepared documents for the management of complications:
These include:
Protocol for the detection, prevention and treatment of central vein thrombosis.
Protocol for the management of catheter related sepsis.
Please contact your nutrition nurse specialist for a copy of the above.
InfectionDefinition of catheter related blood stream infection (CR, BSI) - “Clinical picture of spiking fever and
chills resulting from blood passage of micro organisms from an intra-vascular infusion system. Isolation
of the same organism from blood and catheter segments is considered definite proof”.
Definitions for CR, BSI Exit site infection – erythema, tenderness, induration or purulence within 2cm of the skin at the exit
site of the catheter
Tunnel infection- erythema, tenderness and induration in the tissues overlying the catheter and > 2cm
from the exit site
Catheter related bloodstream infection (CR, BSI) - isolation of the same organism from a semi-
quantitative or quantitative culture of the catheter segment and from the blood of a patient with
accompanying clinical symptoms of BSI and no other apparent source of infection
(Guidelines for prevention of intravascular device related infections: an overview 1996)
In practice, CR, BSI would be diagnosed by positive central blood cultures, clinical signs of septicaemia,
even in the absence of negative peripheral blood cultures.
The detection and treatment of CR, BSI This protocol should be available for all staff looking after patients on Home Parenteral Nutrition (HPN).
The decisions on whether to use antibiotics, to treat the sepsis or to immediately remove the catheter are
based on the:
type of micro-organism present
continuing need for the catheter
venous access of the patient
Scottish HPN Managed Clinical Network ProtocolsRevised August 2010 - For revision August 2013
18
future need for PN
the general condition of the patient
previous or recent CR,BSI (recent sepsis sensitivities)
If patient with a central venous access device presents with an acute febrile episode:
Assess: history and examination to exclude other infections
Blood cultures (from each lumen): 1 x peripheral
1 x central
see Protocol – minimum volume required 0.5ml/bottle
- Check with local microbiologist
Blood sample for FBC & CRP, U+E’s, LFT’s, ESR glucose + creatinine
Exit site swab if inflamed
Chest X-ray(if clinically indicated)
Urinalysis / urine culture
Other samples as directed by assessment
Then follow protocol for suspected CR, BSI (see over).

If patient develops pyrexia or becomes clinically unwell stop PN while awaiting result of exit site swab
Consider the use of peripheral intravenous fluids or peripheral Parenteral Nutrition
If peripheral and catheter cultures negative If cultures from catheter or exit site swab
positive
Recommence PN. Monitor patient during first administration of PN. Record temperature 4 hrly
If patient becomes clinically unwell or pyrexial
Seek guidance from the microbiologist regarding most appropriate treatment
**Remove catheter if cultures positive with
staph aureus, or candida.
**If catheter infected with staph epidermis it may be possible to treat
After completion of antibiotic therapy, recommence PN, monitor patient during first administration of PN. Record temperature 4 hrly.
* Administering antibiotics via the central catheter is favoured. Treat with Vancomycin, and cefuroxime/or gentamycin.Guidance should be obtained from the microbiologist on call.** The decision when to remove a catheter is complex, there are several factors that need to be taken into account.The type of microorganism present, continuing need for the catheter, venous access of the patient and the general condition of the patient. It is generally not advisable to treat a staph aureus or candida sepsis however each patient must be considered individually.*** In paediatrics this may be the only IV access available.
CONFIRMED LINE INFECTION
If line infection is confirmed, consideration must be given to catheter removal and antibiotic treatment.
Catheter removal was once thought essential in the treatment of line infection but in recent years
catheter salvage rates of around 50% have been reported using antibiotics. Attempts at catheter salvage
are certainly justified in stable patients with blood stream infections with Staph epidermidis. Tunnel
infections with obvious pus are unlikely to respond to antibiotics. Exit site infections may be successfully
treated. Blood stream infections with coagulase positive staphylococci, MRSA, gram negative bacteria,
and yeasts are more dangerous and serious consideration should be given to catheter removal.
However, as far as possible catheter salvage should be attempted. Discuss with the nutrition team
consultant or SR and microbiologist prior to line removal. In particular yeast infections carry a significant
risk of spread to the eye with potential for loss of sight (Nightingale 1995). Therefore catheters infected
with yeasts should virtually always be removed. For other infections the benefits of more certain
eradication of sepsis by catheter removal must be balance against the difficulty of venous access in that
patient.
Antibiotic treatment depends on the bacterial sensitivities. Vancomycin administered into the catheter is
the mainstay but the antibiotic used will depend on local bacteriological advice. It seems sensible to
infuse the antibiotics down the catheter but this must be done with sterile precautions, preferably with the
antibiotic made up in the pharmacy sterile unit. If a single daily dosage can be given the number of
catheter interventions is reduced. Thereafter the antibiotic can be left in the catheter before flushing at
the commencement of the next infusion.
Confirmed line infection: Complications Port abscess
Septic thrombosis
Endocarditis
Osteomyelitis
Consider line removal and treat, guided by sensitivities and advice from pharmacist and
microbiologist.
General comments1. Consider line cultures at end of treatment completion where line salvage attempted.
2. Nearly every patient will require peripheral access for continued fluid and nutritional needs.
Scottish HPN Managed Clinical Network ProtocolsRevised August 2010 - For revision August 2013

3. Consider advice from a microbiologist when planning a new line insertion. The interval before line
insertion is determined by the clinical case. Preferably, antibiotic treatment should be completed
before CVC insertion.
4. Consider screening fro MRSA and topical treatment in keeping with agreed local protocols.
5. When patients are slow to recover, consider complications and further investigation. Access to trans-
oesophageal echo-cardiograph may be helpful
6. Consider re-assessing patient line care technique.
Catheter occlusion There are many factors that may lead to occlusion of the central venous access device
Malposition of the catheter
A kink in the catheter
The formation of a fibrin sheath at the tip of the catheter can act as a one-way valve, allowing
saline to be flushed but preventing the withdrawal of blood into the catheter.
Fibrin deposits caused by the formation of a clot due to stagnate blood which has been left within
the lumen of the catheter
Lipid sludge caused by the formation of lipid deposits
Drug precipitation
Factors affecting the incidence intra luminal occlusion: Catheter material
The catheter flushing technique
Inappropriate use of heparin solution

Flushing the catheter The patency of the CVAD should be checked prior to administration of feed. Central venous catheters
should be flushed with an anticoagulant when the device is not in regular use, unless advised otherwise
by the manufacturer (Pratt et al., 2007). It is usually recommended that pressure-activated valved
catheters and some positive pressure flush devices are flushed with 0.9% sodium chloride (Camp
Sorrell, 2004; INS, 2006; Pratt et al., 2007). The volume of the flush solution should be equal to at least
twice the volume of the catheter and add-on devices – usually 5–10 ml. The concentration of heparin
should be the lowest possible that will maintain patency – usually 10iu heparin in 1 ml 0.9% sodium
chloride (except with implanted ports which may require 100iu/ml heparin). Frequency of flushing should
be weekly for long term central venous access devices, unless occlusive problems indicate otherwise
(Kelly et al., 1992; Dougherty and Watson, 2008) or every 4 weeks for an implanted port (Camp Sorrell,
2004). Flushing with 0.9% sodium chloride solution to ensure and maintain patency should be performed
using a pulsated push-pause and positive pressure method. (NICE, 2003; INS, 2006).
Detection of an intra luminal occlusion:
1. Determine whether there is a mechanical cause for the blockage
2. Rule out a kink in the tubing or an external force causing obstruction
3. Arrange for a chest X-ray to be carried out to determine the position of the tip of the catheter.
4. Exclude the presence of a central venous thrombosis
5. If the catheter remains blocked, aspirate the catheter then flush with saline. Do not use extreme force
as forceful flushing can rupture the catheter and cause serious problems to the patient e.g. transitory
embolus. A syringe smaller than 10 ml should not be used due to the increased pressure that can be
exerted on the catheter
6. If the catheter remains occluded determine the most likely cause of occlusion, and consider
treatment options
Treatment options – see Protocol for the detection, prevention and treatment of central vein thrombosisFibrin deposits
Fibrin deposits may respond to the administration of urokinase (Wachs 1990). Obstructed catheters are
injected with 5,000 units of urokinase, left in situ for an hour, then aspiration of the solution and residual
clot attempted. If aspiration is unsuccessful, repeat attempts can be made. If this remains unsuccessful,
Scottish HPN Managed Clinical Network ProtocolsRevised August 2010 - For revision August 2013
23
a urokinase infusion of 40,000 units can be infused over 6 hours. If occlusion is still present a further 6
hour infusion of 40,000 units can be prescribed.
Lipid Occlusions
The use of lipid 3 in 1 mixes can result in the presence of lipid deposits within the lumen of the catheter.
In an attempt to prevent this problem, some centres infuse the lipid infusion separately however the
practicality of this for the patient on home parenteral nutrition is much more difficult. The use of 70 %
ethanol solution can often clear the catheter (Pennington 1992). Replacing a saline flush with a 20 %
ethanol flush after lipid infusions may also prevent the problem of lipid occlusion.
Obstructed catheters are injected with 4 ml of a 70% solution of ethanol in sterile water. Ethanol is left in
the catheter for an hour then aspirated and flushed.
Drug Precipitation / Mineral deposits
Catheters can become blocked with drug precipitation or a build up of mineral deposits. These can
occasionally be reversed by the use of hydrochloric acid 0.1% in 3ml (Werlin et al 1995).
Ter Borg et al (1993) suggest that central venous access devices, which are unresponsive to treatment
with urokinase, ethanol, or hydrochloric acid, can be unblocked with a perfusion of 10 to 20 ml of 0.1
sodium hydroxide solution. They do point out however, that it is important to establish the safety of
catheter materials before attempting to administer a sodium hydroxide solution.
Fractured / Ruptured central catheters
Reasons for rupture
Rupture from an attempt to irrigate occluded catheter with a small syringe. Infusion pressures should
never exceed 25 psi. As smaller syringes generate more pressure than larger syringes, the catheter
should be never be flushed with a syringe smaller than 10 ml
Repeated clamping (wear and tear)
Contact with a sharp object (accidentally cut or pierced)
Scottish HPN Managed Clinical Network ProtocolsRevised August 2010 - For revision August 2013
24
Rupture of the external part of the catheter is often easily detected as leakage of PN solution can be
seen. However internal fractures, which can cause infiltration of fluids into the surrounding tissues, may
not be easily recognized. Symptoms of pain and swelling around the catheter may alert staff to the
problem. A diagnosis can be made by the use of contrast studies (Verhage and Van Bommel 1999). If an
internal fracture is diagnosed the catheter should be removed immediately.
What to do if the event of an external catheter rupture
1. When damage occurs, the catheter should be immediately clamped or kinked to prevent the
possibility of air embolism, loss of blood or entry of microorganisms.
2. The catheter should be clamped between the catheter exit site and damaged area. The clamp must
remain in place during the repair procedure.
3. To repair the damaged external segment of the catheter it is recommended that there is at least 3cm
of undamaged catheter remaining beyond the skin exit site.
4. The catheter can be repaired on several different occasions, as long as there is sufficient length of
catheter externally.
It is important that the patient has access to the following:
A clamp to seal off the catheter in case of fracture or puncture
A repair kit and silicone gel which is within 'use by' date should be held in the designated area of the
hospital……………………………………………………………………………………
A supply of Urokinase and alcohol should be held in the parent ward of the hospital
Urokinase is available from pharmacy in 10000 unit ampoules of freeze dried powder
One ampoule mixed with 2ml water provides 5000 units / ml
This 1ml should then be diluted to 3ml with sodium chloride
The dosage is 5000units in 3ml
The paediatric dose is 5000 unit in 2 ml
The patient on HPN should be given written instructions on the first- aid management of an external
catheter rupture. Each patient should be supplied with a small clamp at home.
Repair of ruptured catheters
Scottish HPN Managed Clinical Network ProtocolsRevised August 2010 - For revision August 2013

1. Contact nursing/medical member of multidisciplinary nutrition team
2. The appropriate repair kit should be available
3. The catheter repair is carried out under strict aseptic technique as per manufactures instructions
4. If necessary the catheter may be used after 4 hours, although the joint will not achieve full
mechanical strength for 48 hours. If possible the catheter should not be used for 48 hours,
decreasing further risk of rupture/fracture.
5. A prophylactic antibiotic may be of use if appropriate.
