Clinical Trial Summary

Objective: To evaluate color Doppler flow ultrasound compared to standard clinical techniques, to detect the correct position of peripheral intravenous catheters in adult surgical patients.

Methods: A prospective study is conducted in adult (>18 years old) patients scheduled to undergo elective surgery. Peripheral intravenous catheter position is evaluated with standard clinical techniques (free flow of fluid from a hanging bag, easy saline injection, and aspiration of blood), and with color flow Doppler ultrasound proximal to the insertion site. Comparative test performance is carried out.

Description:

Confirmation of adequate peripheral intravenous catheter placement should be determined before using the parenteral route; however, there is no gold standard universally accepted for this purpose. Determination of the correct position of freshly inserted peripheral intravenous catheters and already established intravenous lines depends largely on subjective clinical signs such as visual evidence of swelling around the insertion site, low resistance to infusion and free back-flow of blood. Ultrasound-guided cannulation of peripheral veins has gained popularity in recent years and is standard of practice in some institutions. Primarily used in guiding central line placement, the applications of ultrasound for vascular access continue to expand in the perioperative setting, thanks to its easy use, non-invasiveness and safety profile. On the other hand, utilization of color Doppler technology with flow injection test has been shown to be a valuable tool for early recognition of malfunctioning intravenous catheters. The color Doppler flow technique is both safe and reliable, and aids in identification of correct intravascular position of venous catheters in children.

This study aims to test the hypothesis that the color Doppler flow technique is superior to standard clinical techniques (free flow from a hanging intravenous fluid bag, aspiration of venous blood with syringe, and non-obstructed hand injection of 2 mL of normal saline) to detect the correct position of peripheral intravenous catheters in adult surgical patients.
