Filter by:Investigators aimed to explore the feasibility of smart glasses connected to a wireless ultrasound transducer for the peripheral venous access. Residents who have basic skills of ultrasound guided procedure participate in the simulation. Each participant plays the following two roles for ultrasound guided peripheral venous access; ultrasound guided peripheral venous access with and without wearing smart glasses. The order of performing two roles is determined by a randomized process and the gap between two roles are five days. The primary outcome is the time of successful blood aspiration, and secondary outcomes are first time success rate, the number of skin puncture, the number of needle redirection, the number of head movement, and subjective difficulty.
When performing vascular cannulation such as radial artery cannulation, ultrasonography (US) helps proper positioning of the tip of needle in the vascular lumen, which facilitating cannulation of the catheter and successful pressure monitoring. Conventionally, short-axis out-of-plane (SAX) and long-axis in-plane (LAX) views are commonly used method to image the target vessel during cannulation under US guidance. Dynamic needle tip positioning (DNTP) method is newly introduced by one group of investigators who conducted a related study using vascular phantom model. In DNTP, SAX is used, and additionally, when the needle tip is imaged in the screen as an echogenic point, the practitioner (a) proximally moves the US probe a bit, and then (b) the needle is advanced until the needle tip reappears in the screen. In this manner, the practitioner repeats (a) and (b) until the needle is inserted 1 cm into the lumen of vessel, and then the catheter is inserted to finish the procedure. DNTP has not been compared to conventional imaging methods. The aim of this trial is to see the effect of DNTP on success rate of the radial artery cannulation at the first attempt, compared to the conventional LAX.
This interventional simple-blind,randomized trial has included 90 children of American Society of Anesthesiologist (ASA) physical status I or II aged between 1 to 12 years of either sex, scheduled for for outpatient minor surgery under general anesthesia. This study examined whether one should make iv attempts during the early induction period (at 60 seconds) or lately (90 or 120 s) and waiting until the child receives additional sevoflurane inhalation anesthesia.
Septi-PICC study aims at assessing incidence of Peripherally Inserted Central Catheter (PICC)-related infections among patients managed in the University Hospital of La Reunion for PICC setting.
To randomize 108 patients undergoing knee replacement surgery to catheter through needle or catheter over needle femoral nerve blocks, then monitor the catheters for leakage to see if there is a difference.
Central venous catheters are needed in the critical care setting to administer drugs. Three sites are available to gain vascular access: subclavian, internal jugular and femoral. Each site has complications, but there is no randomized controlled study which compared the 3 sites. The investigators hypothesis is that subclavian catheterization reduces the risk of major complications compared to internal jugular or femoral.
Traditional teaching that suggests the ipsilateral nipple as the directional guide for needle advancement during Internal Jugular Vein (IJV) catheterization has weak grounds. The investigators attempt to validate this long-standing statement.
Children fear having an intravenous (IV) needle placed because of the pain that they will experience. The more needle punctures that a child has to endure before the IV is successfully placed, the greater the pain experienced and anxiety suffered. In addition, false starts increase the demands on medical staff and can increase the length of the emergency department stay. Often, veins are difficult to see or feel, particularly in an unwell, dehydrated child or in young infants who have more fat below the skin surface. Also, the venous pattern below the skin surface naturally varies from person to person and therefore success in placing IVs leaves room for improvement. Technology may be able to play an important role is improving the rates of success. The investigators wish to investigate whether the use of either an Ultrasound machine or a VeinViewer machine can improve the rate of success of the initial attempt (skin puncture) at peripheral IV placement in comparison to the current standard approach.
The aim of this study is to evaluate the optimization of local anesthetic effect with duplex ultrasound-guided injection of lidocaine before femoral artery puncture during diagnostic or therapeutic interventional procedures. In total, 200 patients scheduled for various diagnostic or therapeutic interventional radiology procedures requiring femoral artery puncture, will be randomized in two groups after informed consent. Patients will be randomized to undergo groin local anesthesia with the proposed method of duplex ultrasound guided injection of lidocaine versus standard injection of lidocaine with manual palpation (control group). The protocol includes the registration of patients' demographics (age, gender, risk factors for peripheral arterial disease), arterial morphological characteristics (calcifications and presence of atheromatous disease), as well as technical details of the procedure (total puncture duration, sheath size, antegrade/retrograde puncture, etc.) Primary study endpoint will be peri-procedural pain that will be assessed with the use of a visual analog scale (VAS) completed by the patient at the end of the procedure. Secondary study endpoints will evaluate procedural safety and complications during the immediate post-procedural period (up to 7 days).
The purpose of this study is to evaluate healthy volunteers perception of catheterization with LoFric catheters with new solvents in the manufacturing process. The subjects will be catheterized three times during one visit day. The hypothesis is that the subjects' perception of catheterization is the same when using the test catheters compared to the reference catheter.
