Filter by:The aim of this study was to evaluate the design and ergonomic use of central jugular vein catheter lumen holder.
In this observational study, we will measure the shortest distance from the cricoid cartilage level to the puncture site of the introducer needle when anesthesiologists perform central venous catheterization.
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.
Central venous lines insertion are common procedures these days. CVL placed under USG guidance have high success rates and low complications even in developing country settings. However, the investigators still have to rely on chest x-ray (CXR) to confirm the correct placement of central venous lines as a gold standard method. This might be time consuming and may cause delay in initiation of treatment. In some cases, as in operating room, the treatment is started even before confirmation by CXR. Ultrasound has ability to localize the tip of the catheter at the superior venacava- right atrium junction using agitated saline and the appearance of contrast within 2 seconds in right atrium. However, this technique is rarely used. The investigators, therefore, designed the trial to study whether confirmation of tip of CVL by ultrasound is non-inferior to the CXR confirmation.
The duration and adverse events of non-cuffed catheter in patients with hemodialysis will be investigated by multicenter prospective cohort. Totally, 1,400 patients with chronic renal failure requiring hemodialysis will be enrolled. 900 patients will be given right internal jugular catheterization, and the other 500 patients unsuitable for right internal jugular catheterization will receive femoral catheterizations. Every patient will be followed-up for six months. During following-up period, the duration time and adverse events of non-cuffed catheter will be recorded in details, including inadequate hemodialysis blood flow, venous stenosis, venous thrombosis, infection, catheter thrombosis and so on. The central vein will be evaluated by CT Angiography to identify its stenosis at last visit after 6 months. This multicentre trial will provide evidence to develop guideline for duration time of using non-cuffed catheter.
