Filter by:OBJECTIVES The primary objective is to compare if the addition of a needle guide can reduce the number of central venous catheter (CVC) insertions with >1 skin puncture in ultrasound-guided catheterization of the subclavian vein using the long-axis approach with an in-plane needling technique. Secondary objectives include if this addition 1) decreases the frequency of mechanical complications (defined as bleeding, arterial puncture, arterial catheterization, nerve injury, pneumothorax), 2) increases the time when the needle is visible, 3) decreases the time until successful vessel punction, 4) decreases the number of needle redirections during the insertion, and 5) a comparison between the two groups regarding number of failed catheterizations. DESIGN This is a prospective, randomised, controlled, parallel intervention study. Patients will be enrolled at Skåne University Hospital in Lund, Sweden. The trial is investigator-initiated and non-commercial. POPULATION AND INTERVENTION Adults (18 years of age or older) in need of a subclavian CVC for any reason and able to give written informed consent will be included in the study provided no exclusion criteria is fulfilled. OUTCOMES Primary outcome will be number of CVC insertions with >1 skin puncture. Secondary outcomes include comparison between the two groups regarding 1) the frequency of mechanical complications, 2) proportion of the insertion-time when the needle is visible on the ultrasound (US) screen, 3) time to successful vessel punction, 4) the number of needle redirections during the insertion, 5) number of failed catheterisations, 6) Feasibility of the needle guide evaluated with a questionair to the operators at the end of the study.
The primary aim of the current study is to examine the accuracy of the C-distance or surface landmarks in determining the length of central venous catheter (CVC) that is required to place the catheter tip at the mid-superior vena cava (SCV) as confirmed by transesophageal echocardiography (TEE). A secondary aim is to derive an equation or formula to calculate the depth of the CVC that is required in order to have the catheter tip placed at the mid-SVC.
When the left internal jugular vein catheterization under short-axis ultrasound guided, an operator should be stand around the lying patient's head. The investigators are going to evaluate to effects of the operator's location.
The purpose of the study is to evaluate the impact of arm abduction and adduction on the intravascular electrocardiograph during PICC placement and to find out how arm position influences the catheter tip location by taking postprocedural chest X-ray radiographs.
Ultrasound (US)-guided central venous catheterization is now considered standard of care according to recent clinical evidence, at least considering jugular vein approach. Recent trials suggested that even US-guided subclavian approach could be more effective that landmark technique. However, studies comparing both sites employing US are still lacking. We, therefore, designed a non-inferiority randomized controlled trial to compare these sites, both using US guidance, according to immediate complications following central venous catheterization.
