Up to two-thirds of intensive care unit patients require central venous catheterization for which ultrasound-guided placement is now recommended. In this context, the team performed a prospective randomized simulation trial on a mannequin ("reduced torso model"), to compare the standard ultrasound guidance technique with an ultrasound-guided technique assisted by a new needle-steering device. The preliminary results show a statistically significant improvement in subclavian venipuncture (shorter success time, fewer multiple skin punctures, fewer punctures of the posterior wall of the subclavian vein and needle redirection, greater comfort) and argue for a clinical trial to test the performance of this new device in situation with intensive care unit patients. The hypothesis is that the needle-steering device will result in a better success rate of subclavian venous cannulation, at first puncture, compared with the conventional ultrasound-guided technique.
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.
Ultrasound-guided axillary vein catheterization can be performed via the oblique-axis and long-axis approaches 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 high bleeding risk
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.
This was a prospective randomized study. After prior approval by the Ethics Committee, we included all patients aged over 18 years- old who were admitted to the intensive care unit (ICU) and who required a central venous catheterization (CVC) outside the emergency's context. Non-inclusion criteria were thrombosis of the vein or coagulopathy. All catheterizations were done by the same non-experimented practitioner. Patients were randomized into two groups according to the catheterization's technique of subclavain vein: real-time long axis ultrasound guidance (US group) and anatomical landmarks ( LM group). The main outcome was success. The secondary outcomes were: success' rate at first puncture, number of punctures, rate of redirections, number of redirections, access's time, preparation and spotting time and rate of complications (arterial puncture, hematoma, pneumothorax, wrong position of the catheter). Data analysis was performed using the SPSS® software version 20: The Student's "t" test was used to compare the normally distributed quantitative variables, the Mann-Whitney's test for non-normally distributed quantitative variables and the Chi-square and Fisher tests for qualitative data. A value of p <0.05 was considered as statistically significant.
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.
Conventionally, short-axis out-of-plane (SAX) or long-axis in-plane (LAX) ultrasound views are commonly used to guide internal jugular vein catheterization. SAX dynamic needle tip positioning (SAX-DNTP) is a novel ultrasound imaging technique that enables continuous visualization of the needle tip during ultrasound-guided cannulation; When the needle tip is imaged as a hyperechoic dot, the ultrasound probe is moved a few millimeters, and then the needle is advanced until the needle tip reappears in the vessel lumen. The process is repeated until the needle is advanced more than 1 cm into the lumen. The catheter is then introduced into the vessel. The aim of this study was to compare the first pass success rate of internal jugular vein catheterization between SAX-DNTP and the conventional LAX technique.
This study aims to find out the effect of contra lateral head rotation to distance and overlapping of internal jugular vein and carotid artery at cricoid cartilage level by ultrasound guidance on the Malay race in Indonesia
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.
