Detailed Description
Peripheral intravenous (PIV) therapy is one of the most common invasive procedures performed in US hospitals. A majority of hospital patients require intravenous therapy each year in the United States. Despite widespread use, a number of potential complications can occur during PIV therapy. One of the most common causes of IV complications is IV infiltration or extravasation. Infiltration is the leakage of non-vesicant fluids like saline into the surrounding tissue. Extravasation is the leakage of vesicant fluids, which include cytotoxic drugs, intravenous nutrition, and calcium, potassium, and bicarbonate solutions. If not detected and corrected early, infiltration and extravasation can lead to significant complications such as severe inflammation, compartment syndrome, and skin necrosis.
ivWatch, LLC has developed an investigational device that may detect IV infiltration and extravasation occurrences using a near infrared light sensor. Previous studies have evaluated the performance of the ivWatch device by comparing to a nurse's diagnosis. The nursing standard of care relies on tactile and visual indicators to diagnose an infiltration event. The ivWatch product often signals an infiltration event before these indicators are apparent to clinicians. Consequently, comparisons to the nurse's diagnosis often lead to questionable false positives for the ivWatch device. A better reference is required to evaluate the performance of the ivWatch device.
The purpose of this research study is to evaluate the ability of ultrasound to detect PIV infiltrations. Ultrasound is a depth-resolved imaging technique for evaluating tissue microstructure. Researchers have used ultrasound to examine exogenous fluids injected into cutaneous and subcutaneous tissue. Ultrasound has been used to detect small volumes of fluids such as cosmetic fillers and subcutaneous injections. These studies suggest ultrasound may be a potential reference standard for future evaluation of ivWatch devices.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Test diagnostic performance of ultrasound imaging for detection of peripheral IV infiltration.
Time Frame: Within 15 minutes of intentional PIV infiltration
|
Ultrasound images are acquired before and after the induced infiltration on the test arm.
Two additional ultrasound images are acquired from the normal control arm.
At the end of the study, the before and after images from the test and control arms are evaluated and classified by clinicians blinded to the state of the tissue.
Sensitivity and specificity metrics are used to evaluate the performance of ultrasound imaging for assessing peripheral IV infiltration.
