IV Contrast Administration: Effect of Three Side Hole Infusion Catheter on CT Image Quality, Infusion Pressure, and Infusion Rates, Compared to a Standard Infusion Catheter
The purpose of this research study is to compare two types of catheters used for infusing the contrast dye necessary for viewing internal organs during computed tomography (CT) scanning.
The standard catheter, which has one hole from which contrast dye enters veins, will be compared to the Becton Dickinson Nexiva Diffusics System catheter, which has three holes for diffusing dye into veins.
The purpose of this study is to determine which catheter type gives the best image.

Descrição detalhada
This will be a prospective, randomized, controlled trial.
The catheter is already in use at our facilities.
After informed consent, patients will be randomly given the standard or new catheter in our practice.
Envelopes with the random assignment will be available to the individuals consenting patients.
Randomization generally ensures that study groups are similar on average.
As age, sex, and weight impact image quality, we will collect data on these factors in case randomization results in an imbalance.
This will allow for control of these factors in analysis of the data.
Data will be collected from CT abdomen pelvis examinations within a 6 month-1 year period in 2016 - 2017.
Our primary outcome is image quality, measured as tissue density and distribution of contrast within the liver, spleen, aorta and IVC.
Our secondary outcomes include Peak Contrast Infusion Pressure and Injection Flow Rate.
Possible adverse events for use of any type of catheter include contrast infiltration into the subcutaneous tissues which is a minor limited event.
All infiltrations will be recorded as part of the permanent medical record, documented in the chart, and the referring physician notified.
The patient will be assessed by a physician immediately and referred to the ED if necessary for further evaluation.
Current technology utilizes Power injector equipment which alerts the technologist to the pressure being achieved.
If the injection pressure exceeds 325 psi the Power injector automatically shuts off.

Experimental: Becton Dickinson Nexiva Diffusics System
Intervention with the new Becton Dickinson Nexiva Diffusics System will be evaluated to see if it will improve image quality compared to the standard catheter.
|
Becton Dickinson Nexiva Diffusics System will be used to inject IV contrast and will be compared to a single hole catheter to see if it improves image quality in the main vessels in the abdomen and pelvis because of its novel design.

Comparador Ativo: Standard intravenous catheter
Standard catheter with one hole at the tip will be compared to novel 3 hole Becton Dickinson Nexiva Diffusics System to see which catheter provides the best image quality.

Medidas de resultados primários

Descrição da medida |
Prazo |
|---|---|---|
|
Image Quality as Assessed by Ratio of Tissue Density of Main Portal Vein (MPV) to the Aorta
Prazo: at the time of CT scanning
|
The ratio of tissue density measured in the main portal vein (MPV) to tissue density in the aorta on the CT images will be determined and will provide a measure of biodistribution, which is an important indicator of image quality.
Dividing each Hounsfield unit measurement by the aorta density and determining these ratios will be done on a per patient basis to assess biodistribution as a measure of image quality.

|
Image Quality as Assessed by Ratio of Tissue Density of Spleen to the Aorta
Prazo: at the time of CT scanning
|
The ratio of tissue density measured in the spleen to tissue density in the aorta on the CT images will be determined and will provide a measure of biodistribution, which is an important indicator of image quality.
Dividing each Hounsfield unit measurement by the aorta density and determining these ratios will be done on a per patient basis to assess biodistribution as a measure of image quality.

|
Image Quality as Assessed by Ratio of Tissue Density of Inferior Vena Cava (IVC) to the Aorta
Prazo: at the time of CT scanning
|
The ratio of tissue density measured in the inferior vena cava (IVC) to tissue density in the aorta on the CT images will be determined and will provide a measure of biodistribution, which is an important indicator of image quality.
Dividing each Hounsfield unit measurement by the aorta density and determining these ratios will be done on a per patient basis to assess biodistribution as a measure of image quality.

Image Quality as Assessed by Rating Scale
Prazo: at the time of CT scanning
|
Radiologists blinded to catheter type will review images and rate them on a scale of 1 to 10. 10 indicates a better outcome.
