Designed With CT Scans in Mind

Address common IV challenges encountered during CT scans

The unique diffusion tip of BD Nexiva Diffusics™
Closed IV Catheter System adds three laser-cut teardrop holes around the catheter tip. It can accommodate power injection up to 325 psi and meet high flow injection protocols.*

Nexiva Diffusics™ Catheter System is built on the Nexiva platform and is specifically designed to address the infusion challenges of contrast-enhanced CT.

*22 G up to 6.5 mL/sec

Common CT Infusion Challenges

High flow rates have traditionally required large gauge catheters

Unfortunately, many patients’ vasculature cannot accommodate 18- or even 20-gauge catheters, and using smaller gauge sizes can result in slower flow rates and reduced image quality.

High flow rates may cause catheters to whip around in the vein.

While achieving appropriate flow rates is crucial to image quality, the high flow rates required for power injection during CT may also cause catheters to move or whip around in the vein which may lead to extravasation and could be costly.1,2

Enable higher flow rates with smaller gauges

The Infusion Therapy Standards of Practice recommend placing the smallest-gauge catheter that will accommodate the prescribed therapy and patient need.3

The diffusion tip on Nexiva Diffusics™ Catheter System enables desired contrast media flow rates to be achieved using a smaller gauge catheter† without compromising image quality. This enables clinicians to perform CT scans that require high flow rates when a patient's vasculature cannot accommodate a large catheter (i.e., 18 or 20 gauge).‡,4 

†22–24 gauge

‡Bench test results may not necessarily be indicative of clinical performance.

Reduce the force of contrast delivery

While flow rates of contrast media are important, the delivery force should also be considered. Nexiva Diffusics™ Catheter System’s diffusion tip reduces the force of contrast delivery by up to 48%,§ helping decrease the impact of contrast media on the vessel wall.

§Compared to a non-diffusion-tip catheter. Bench test results may not necessarily be indicative of clinical performance.

Decrease potential catheter motion in vein

High flow rates required for power injection during CT may cause some catheters to move or whip around in the vein. Catheter motion may lead to extravasation, a complication caused by the catheter backing out of the vein.1

Extravasation may be painful for the patient, potentially resulting in tissue damage.3 The average potential liability for a moderate extravasation is $22k and up to $145k for a severe extravasation.2

Nexiva Diffusics™ Catheter System has been shown to reduce the forces that may cause catheter motion in the vein by up to 67%. This reduction in force stabilizes the catheter in the vein, and prevents the whipping, movement and backing out of the vein that may lead to extravasation.1

The videos below show catheter motion and extravasation of a non-diffusion tip catheter compared to the stability that Nexiva Diffusics™ Catheter System provides during power injection.

Power injection through a non-fenestrated catheter: Extravasation

Note that, due to the force of the injection, the catheter tip will slowly move, backing out of the vein until the tip escapes the vein completely and contrast media enters the surrounding tissue.

Power injection through a non-fenestrated catheter: Catheter Motion

Note the catheter stays in the vein, but the forces from the power injection create enough turbulence to cause the catheter tip to whip around within the vein. This creates significant motion, potentially irritating or damaging the vessel wall.

 Note the contrast media flows throughout the vasculature, while the catheter remains still.

Nexiva Diffusics™ Catheter System for cardiac CTs

The all-in-one closed IV catheter system leverages a fenestrated tip to accommodate power injection at high flow rates (e.g., 6.5 mL/sec for 22 G) and provides higher vascular attenuation for coronary CTA (CCTA) when compared with non-fenestrated catheters at the same flow rates.



Practice guidelines include using a fenestrated peripheral IV catheter (PIVC), ensuring the IV used is rated to administer flow rates required for coronary CTA (e.g., 5–7 mL/s).1

CCTA benefits

  • ensures high risk patients are appropriately triaged to cardiac catheterization1

  • offers rapid evaluation of the degree of coronary stenosis and atherosclerosis1

  • allows significant reduction in time-to-discharge1

CCTA conditions

  • Appropriate utilization and patient selection1

  • Requires high contrast media injection flow rates2

Extracting potential clinical and economic value for CCTA includes improving patient outcomes, lowering healthcare costs and preventing unnecessary diagnostic procedures.1

Achieving high diagnostic accuracy with the lowest possible radiation dose requires careful preparation of CTA patients.1 Adequate peripheral IV access is necessary to ensure diagnostic, high-quality images.2


Image quality is affected by the attenuation achieved in MDCT coronary angiography, particularly in the small coronary arteries. Overall diagnostic accuracy improves significantly when higher intracoronary attenuation is achieved.4 Nexiva Diffusics™ Catheter System has been shown to provide higher vascular attenuation for CCTA when compared with non-fenestrated catheters at the same flow rates.*,5,6


Morbid obesity in CCTA

Morbid obesity is a scenario where CCTA may be difficult or non-diagnostic. Strategies to improve image quality include ensuring high-flow IV contrast injections of 6–7 mL/sec.1 Nexiva Diffusics™ Catheter System can accommodate power injection at 6.5 mL/sec for 22 G and up to 15 mL/sec for 18 G.


*The catheter system has been tested at the flow rates noted for contrast media viscosity 27.5 cP(mPa-s). However, due to variations in add-on devices, tubing, contrast media temperature and pressure limit settings, these flow rates may not be achievable.


Acute chest pain in CCTA

CCTA is a proven strategy to safely expedite diagnosis and limit resource utilization for patients presenting with acute chest pain (ACP) in the ED with no known prior coronary artery disease.1




CCTA has established itself as the preferred first-line test for ACP triage in select patients, and is also now recognized as a Class I indication by multiple international professional societies, including the American College of Cardiology, the American College of Radiology, and the European Society of Cardiology.1


Infusion Therapy Standards of Practice state to consider a fenestrated catheter for a contrast-based radiographic study.8 Nexiva Diffusics™ Catheter System is the only peripheral IV catheter with a fenestrated catheter tip specifically designed for power injection.


Nexiva Diffusics™ Catheter System is designed to enable contrast delivery during CT with smaller IV catheters without increasing the risk of complications.


The stabilizing catheter system reduces:



  • Force of contrast delivery by up to 48%*
  • Destabilizing effects that may lead to extravasation3
  • Potential for the catheter to move or whip around in the vein
  • Chance of phlebitis by up to 29%†,7


These factors enable power injection with smaller IV catheters without an increased risk of complications. Nexiva™ Catheter System has also been associated with lower complications in a number of studies.
