Common Venous Access Device Problems
Thrombosis or fibrin sheath at catheter tip Catheter-related infection Catheter malposition Device damage or malfunction Extravasation injury
![Page 3: Venous access devices-managing common problems](https://reader035.fdocuments.in/reader035/viewer/2022081417/554b1807b4c9056f098b4e14/html5/thumbnails/3.jpg)
Overall complication rate
1.8% - 14.4% (DiCarlo et al., 2001)
Most common complications:
--- venous thrombosis
--- infection
![Page 4: Venous access devices-managing common problems](https://reader035.fdocuments.in/reader035/viewer/2022081417/554b1807b4c9056f098b4e14/html5/thumbnails/4.jpg)
Most common reasons for device removal (Fischer et al., 2008)*
Infection (46%) End of treatment (34%) Thrombosis (11%) Device dysfunction (6%)
*study of 385 consecutive patients

Education of healthcare providers
The most important strategy for the prevention of venous access-related problems (O’Grady et al., 2002).
![Page 6: Venous access devices-managing common problems](https://reader035.fdocuments.in/reader035/viewer/2022081417/554b1807b4c9056f098b4e14/html5/thumbnails/6.jpg)
Devices lacking blood return
Place patient in supine position Use a 10 mL saline syringe to gently
“push-pull” 53% success rate in 8,685 ports that
lacked a blood return (Goossens et al., 2007)
![Page 7: Venous access devices-managing common problems](https://reader035.fdocuments.in/reader035/viewer/2022081417/554b1807b4c9056f098b4e14/html5/thumbnails/7.jpg)
If repositioning and flushing are not successful Attempt to withdraw blood using 20 mL
syringe Dye study or instill a thrombolytic agent
(TPA) Cardiovascular Thrombolytic to Open
Occluded Lines (COOL) Efficacy Trial (Ponec et al., 2001): TPA injection restored catheter function 90% of the time
![Page 8: Venous access devices-managing common problems](https://reader035.fdocuments.in/reader035/viewer/2022081417/554b1807b4c9056f098b4e14/html5/thumbnails/8.jpg)
Fibrin sleeve or thrombus formation
![Page 9: Venous access devices-managing common problems](https://reader035.fdocuments.in/reader035/viewer/2022081417/554b1807b4c9056f098b4e14/html5/thumbnails/9.jpg)
Thrombotic complications (Kuter, 2004)
Within days of insertion, most catheters are coated with a fibrin sheath.
Most clots arise within 30 days. These clots can cause pulmonary
embolism (most are asymptomatic). Thrombosis of blood vessel increases the
risk of infection.
![Page 10: Venous access devices-managing common problems](https://reader035.fdocuments.in/reader035/viewer/2022081417/554b1807b4c9056f098b4e14/html5/thumbnails/10.jpg)
Local catheter-related infection
Risk factors
--- Poor insertion or care technique
--- Superficial port placement
--- Heat, moisture, friction while port is accessed
![Page 11: Venous access devices-managing common problems](https://reader035.fdocuments.in/reader035/viewer/2022081417/554b1807b4c9056f098b4e14/html5/thumbnails/11.jpg)
Local (port pocket) infection
Culture site Local wound care Systemic antibiotics Remove device if pseudomonas species or
atypical mycobacteria Do not use until signs of infection resolve
![Page 12: Venous access devices-managing common problems](https://reader035.fdocuments.in/reader035/viewer/2022081417/554b1807b4c9056f098b4e14/html5/thumbnails/12.jpg)
Local infection Actions to manage
Local infections most commonly due to Staphlococcus epidermidis
Frequent wound care Systemic antibiotic therapy Catheter may need to be removed if
there is a systemic infection (Staphlococcus aureus) along with local infection
![Page 13: Venous access devices-managing common problems](https://reader035.fdocuments.in/reader035/viewer/2022081417/554b1807b4c9056f098b4e14/html5/thumbnails/13.jpg)
Systemic catheter-related infection
Risk factors--- Grade 4 neutropenia
--- Prolonged neutropenia
--- Administration of total parenteral nutrition
--- Hematologic malignant disease
--- External catheters: 5% to 29% more common
--- Lack of education and training of healthcare
staff
(Maki et al., 2006)

Systemic infection
Actions to manageMost common organism is coagulase-
negative Staphlococcus Quantitative blood cultures from device and
peripheral draw Number of Colony Forming Units (CFU) of bacteria per
mL of blood drawn via the device is 10X or more than the peripherally drawn blood
>1000 CFU in the absence of a peripheral draw Catheter tip cultures positive

Systemic infection
Actions to manageSystemic antibioticsRemoval of catheter with persistent fever
or bacteria for 3 days with antibiotics, especially if Staphlococcus aureus

The Central Line Bundle(Institute for Healthcare Improvement, 2006)
Hand hygiene Maximal sterile barrier precautions during device
insertion Chlorhexidine skin antisepsis Optimal catheter site selection, with subclavian vein as
the preferred site for non-tunneled catheters Daily review of catheter necessity with prompt removal of
unnecessary catheters

Summary
Vascular access-related complications are common occurrences.
Problems may occur even if the device was recently inserted.
Catheter patency and placement should be confirmed prior to administering medications, especially vesicant chemotherapy.
Nurses play a key role in preventing and detecting VAD problems and complications.
