6 Clinical Trials for Various Conditions
This comparative treatment study aims to challenge a current clinical practice. Specifically, whether the use of ultrasound-guided peripheral intravenous catheter insertion results in lower post insertion failure rates with longer utility time compared to peripheral intravenous catheters (PIVC) inserted in the standard manner during the emergency department (ED), observation and in-patient stay. There are two secondary aims to the study: a) determining if ultrasound-guided peripheral intravenous catheter insertion results in lower post removal complication rates compared to PIVCs inserted in the standard manner; and b) determining if catheter-to-vein ratio can predict post insertion success of PIVCs and what catheter-to-vein ratio is most successful. In this study, catheter-to-vein ratio is defined as the diameter of the lumen of the vein divided by the outside diameter of the catheter.
Suture-mediated closure devices are effective and safe for achieving rapid hemostasis in femoral venous access site and reducing the incidence of complications associated with traditional closure methods. Furthermore, there are predictive factors(such as sheath size, obesity, procedure duration, and anticoagulation status)that we can use to assess the procedure's likelihood of success in various patients.
Peripheral intravenous cannulation (PIVC) is one of the most common interventions in medical practice. Venous dilatation is helpful for successful PIV placement. Several techniques include hot pack application, tourniquet, massaging, and tapping over the vein to increase vein caliber described in the literature. However, none of them has been rigorously studied. Therefore, there is still no 'best practice' on how to effect vein dilation in a standard way. This study aims to investigate the effect of standardized tapping on venous dilatation with a massage device compared to manual non-standardized tapping and define a standard tapping technique using a device. In this study, the investigators also aim to investigate the effect of tourniquet application with and without vein tapping effect on peripheral vein caliber as determined by ultrasound measurement.
The objective of this project is to define the effectiveness and therefore the role of NIR vein finders in adult patients with difficult peripheral venous access. The specific objective of the proposed randomized controlled trial is to test the clinical success rate of placing peripheral venous catheters in 'difficult' access patients using traditional peripheral venous catheter placement compared to two established methods utilizing NIR vein imaging. The investigators hypothesize that the capability to successfully place lasting peripheral venous catheters is increased with the adjunct of the imaging technology, reducing the number of failed needle sticks, reducing the number of peripheral venous catheters placed throughout a patient's hospital stay, and reducing the need for more invasive catheters such as PICC lines.
In patients admitted to a coronary care unit, what is the correlation coefficient and limits of agreement for paired measurements of peripheral venous pressure and central venous pressure at multiple time points during the patient's hospitalization?
The purpose of this study is to learn how the use of ultrasound helps with the placement of an intravenous (i.v.) catheter in young children.
