NCT07582107
This study looks at how to place port catheters safely and accurately in children who need long-term intravenous treatment. For these treatments to work well and to avoid problems such as heart rhythm issues, blood clots, or infections, the tip of the catheter must be in the correct position inside a large vein near the heart. Doctors commonly use two different methods to estimate the correct catheter length. One method uses body measurements and surface landmarks on the chest. The other method, called intracavitary electrocardiography (IC-ECG), uses changes in the heart's electrical signal during the procedure to guide placement. In this study, researchers compared these two methods in children. They measured how closely the results of the two techniques matched and how much they differed. After the catheter was placed, chest X-rays were used to check whether the catheter tip was in the correct position. The goal of this study is to determine whether the simpler anatomical method can provide accurate and clinically reliable results compared to the IC-ECG method.
NCT06375252
The aim of this study was to evaluate the design and ergonomic use of central jugular vein catheter lumen holder.
NCT05409768
Ultrasound guidance in central venous catheterization has become the standard for clinical practice. Many approaches have been described in ultrasound guided catheterization procedures. The aim of this study is to compare the classical short axis out of plane (SAX-OOP) approach and the new anteroposterior short axis in plane (APSAX-IP approach in central jugular venous catheterization. The study was planned as prospective randomized and controlled. One hundred patients were planned to be included in this study. Patients will be divided into two groups: Central jugular vein catheterization will be performed with the short axis out of plane group (ultrasound transducer will be positioned classically from medial to lateral in the neck) and anteroposterior short axis in plane group (ultrasound transducer will be positioned laterally from anterior to posterior on the neck). The two groups will be compared in terms of number of puncture attempts, duration of the procedure, ultrasound scan time before the procedure, number of needle redirection, overall success rate, complications, ease of catheterization and ultrasound visibility.
NCT04279808
For safe central catheterization, clinicians must be aware of adequate dilator insertion depth not to directly dilate the venous wall. The purpose of the study is to find out adequate insertion depth of the dilator during central venous catheterization through the internal jugular vein with the aid of real-time ultrasonography.
NCT03395691
Ultrasound-guided axillary vein catheterization can be performed via the proximal or distal approach of the axillary vein. The aim of our study is to compare the first puncture success rate and safety between the two approaches of ultrasound-guided axillary vein catheterization in cardiac surgical patients with risk of bleeding.
NCT02661607
A prospective study to compare the use of point of care echocardiography versus routine chest radiography for the assessment of central venous catheter placement.
NCT01003366
To test the hypothesis that approaching the internal jugular vein with the needle bevel down would produce less injury to the vessel wall compared to the bevel up approach during central venous catheterization.
