Study Notes
Device Selection - General
- Early consultation between the vascular access specialist and patient/family is crucial for optimal outcomes.
- Reviewing patient variables (at admission) and projected therapies helps with timely and appropriate device insertion.
- This reduces complications and ensures safe delivery of treatments.
- Consider patient preferences, daily activities, and lifestyle when selecting the device.
- Understanding of diagnosis and therapy is crucial for patient and caregiver.
- Early consultation ensures the correct device is placed in the right location at the right time preserving vessel health.
Pediatric Considerations
- Device selection may be limited due to smaller vessel size in children, impacting visualization and palpation.
- Multiple attempts, previous complications, and developmental stage are considerations.
- Clinicians need specific training for pediatric vascular access.
- Minimizing venipuncture attempts reduces pain and anxiety, preserving vessels.
- Assessment of age, size, vascular access sites, reason for therapy, duration of therapy, activity and mobility, cognitive ability, gross and fine motor skills, and body image is necessary
Indications for Vascular Access
- Hydration
- Medication administration
- Total/partial parenteral nutrition (TPN/PPN)
- Chemotherapeutic agents
- Blood/blood components
- Clinical/diagnostic needs (monitoring, etc).
- Plasmapheresis/Aquapheresis/Hemodialysis
- Frequent blood sampling in difficult access patients
- Therapeutic phlebotomy
Device Facts
- French Scale (Fr): Measures external diameter of a catheter. Larger Fr numbers indicate larger diameters.
- Gauge Scale (g/ga): Measures inner diameter. Smaller gauge numbers indicate smaller diameters.
- Catheter sizes range from neonatal (1.2 Fr) to dialysis (15 Fr).
- Needle characteristics include single use, various lengths, and bevels. Repeated use can cause damage, site contamination, and dullness.
Peripheral Catheters
- Short and long peripheral IV catheters are used.
- Catheter lengths vary from 0.56" to 2.5" (14mm to 10cm).
- Insertion methods include catheter-over-needle, accelerated, or modified Seldinger.
- Suitable for infusions expected to last 6 days or less.
- Non-irritant and non-vesicant medications are preferred.
- Avoiding areas of flexion (hand, wrist, antecubital fossa) is important during insertion, especially with ultrasound guidance.
Contraindications for Peripheral Catheters
- Therapies expected to last longer than 6 days.
- Infusions with osmolarity greater than 900 mOsm/L.
- Vesicants/irritant medications.
- Placement in compromised areas (e.g. thrombosis, fracture, infection).
- Veins in the same arm as mastectomy, A/V fistula or graft.
- Avoid vessels in the lower extremities in adults.
Insertion Procedures
- Follow manufacturer's instructions and the aseptic non-touch technique.
- Perform skin antisepsis.
- Limit attempts per healthcare provider (e.g. 2 attempts per provider to a maximum of 4 attempts).
- Ensuring at least 50% of the catheter length is within the vein during insertion length considerations are important
- Consider using visualization technology, particularly for difficult cases or when the vessels are difficult to visualize.
- Use proper anatomical landmarks and guidelines during insertion.
Supplies
- Catheter
- Skin antiseptic
- Gloves (consider sterile)
- Extension sets
- Needleless connectors
- Normal saline flush
- Dressing (semi-permeable/antimicrobial)
- Skin adhesive/protectant
- Tissue adhesive
- Stabilization devices
- Alcohol lock should be considered when using polyurethane catheters
- Avoid using alcohol on all devices as it can act as a solvent and may cause degradation
