Peripheral venous catheters PIVCs VS Long peripheral catheters LPCs for Multi day intravenous therapy - Picture of a peripheral venous catheter

Peripheral Intravenous Catheters (PIVCs) versus Long Peripheral Catheters (LPCs) for Multi-day Intravenous (IV) Therapy: Current Evidence

Peripheral venous catheters can be divided into three groups:

  • peripheral intravenous catheters (PIVCs);
  • long peripheral catheters (LPCs);
  • midline catheters (MCs).

Each of them has specific characteristics:

Peripheral intravenous catheters (cannulas)

PIVCs vary between 3 and 6 cm in length and are commonly placed in the veins of the upper limb, distally to the antecubital fossa, and terminate well before the axilla.

Long peripheral catheters

LPCs are 6–15 cm catheters inserted in the forearm or upper arm. The distal tip terminates before reaching the axilla, typically no further than the mid-upper arm.

Midline catheters

MCs are 15–25 cm in length and are inserted into peripheral veins in the forearm or upper arm. The distal tip terminates into the axillary vein (mid-clavicular region).

 

 

Background

 

Intravenous (IV) therapy is one of the most common interventions administered to hospitalized patients. PIVCs, also known as ‘cannulas’, are the standard devices used to deliver IV therapy and are essential for the provision of fluids, basic medications and blood products. However, there is increasing recognition that PIVCs are unreliable after 2-3 days of usage and associated with several complications (Table 1).

Many conditions require multi-day IV therapy; therefore, it is common for a patient to receive multiple PIVCs during a single admission.

Achieving IV access can be a challenging task for both clinicians and patients. Venepuncture in children can be traumatic, especially when the procedure is unsuccessful and multiple attempts are necessary. In addition, the requirement for IV device reinsertions can delay the delivery of crucial IV therapy. LPCs could potentially be more durable than PIVCs, and thereby improve the quality of care in adults and children.

Overall LPCs performance including adults and children:

  • Catheter duration (mean/median time): 1.1 – 14.7 days
  • Failure rate (percentage): 2.0 – 52.5% (most common causes: infiltration, phlebitis, dislodgement, occlusion)

Conclusions

LPCs are safe and reliable peripheral vascular devices in adults and children. In addition, LPCs may represent an improvement to the quality of care, as demonstrated by three RCTs in adults and one randomized controlled trial in children where they outperformed PIVCs.

The results of these RCTs demonstrate that LPCs should be considered the catheter of choice in all patients requiring multi-day intravenous therapy. LPCs have lower failure rates, reduce total number of catheters and will likely improve patient satisfaction.
