Filter by: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.
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
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.
In this randomized clinical study, neonates who require umbilical venous catheter (UVC) insertion as part of their routine care at anytime during their NICU admission will be randomized to one of the 2 formulas for estimation of the pre-insertion UVC depth (umbilicus to the nipple in cm minus 1 (UN - 1) or birth weight based formula ([(3× birth weight (Kg) + 9)/2+1)]. UVC will be inserted under sterile condition as per unit protocol. To verify the UVC tip position, a thoracoabdominal radiograph will be taken. In addition, the investigators will do a ultrasound of the heart to assess the exact location of the catheter tips as soon as possible but within 6 hours of insertion.
Central venous catheter placement is a common procedure in the intensive care unit and is a required skill for all residents working in the critical care setting. Central venous catheters (CVC) are placed for a variety of reasons including administration of caustic medications, administration of fluids or blood products for rapid resuscitation, access for hemodynamic monitoring or transvenous pacing, temporary vascular access for dialysis, or inability to obtain peripheral IV access. CVC's are routinely placed in the internal jugular vein in the Vanderbilt medical ICU and ultrasound guidance is used. Placement of the CVC on the right IJ instead of the left IJ is commonly preferred due to the more direct path to the superior vena cava. However, placement in the left IJ may be necessary for a variety of reasons. The investigators intend to compare the standard practice of residents and nurse practitioners placing IJ CVCs in the medical ICU against mandatory screening of the right and left IJ prior to selection of the CVC placement site. The investigators will accomplish this by assessing the relative first pass stick and overall success rates, the rate of aborted procedures, and the rate of complications between standard practice and mandatory screening of bilateral internal jugular veins prior to CVC site selection.
A prospective study to compare the use of point of care echocardiography versus routine chest radiography for the assessment of central venous catheter placement.
The main objective of this study is to compare the rate of successful establishment of a central venous catheter in the first two attempts of ultrasound-guided puncture between two techniques: (1) a subclavian technique versus (2) an axillary technique.
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.
