Filter by:The purpose of this pre-market clinical study is to evaluate the performance (efficacy) and safety of an autonomous blood drawing device (Venipuncture Device). The study consists of several phases (A, B1, B2, C1, C2, 0). Phase B1 is a confirmatory, Pivotal Clinical Study, required for regulatory approval, in which non-inferiority should be demonstrated in comparison to manual blood drawing. Phases A, B2, C1, C2 are all exploratory studies, in which the technology and usability is further improved and tested. Phase 0 is an exploratory study for non-invasive technology testing (for example for improvement of ultrasound detection). The study locations are outpatient blood drawing departments, in which patients are included as subjects. Additionally, in Phase A and C1, a small number of volunteers is included in a non-hospital site (Vitestro Site).
The purpose of this study is to assess the utility of an augmented reality headset for visualization of ultrasound images during ultrasound guided placement of an intravenous catheter.
The study was planned to determine the effect of using a blood vessel imaging device (VID) and venous blood collection procedure on the pain and satisfaction level of the individual during phlebotomy. The randomized controlled experimental design study was carried out in a blood collection unit in a training and research hospital between 1-15 April 2022. The study sample was calculated as 100 people by power analysis and the method of drawing lots was applied to the groups. Data were collected using the patient identification form, visual analogue scale (VAS), and pain and satisfaction scales.
The aim of the study was to determine the effects of providing procedural informational animation, Buzzy application during the procedure, the combination of both interventions (Animated video and Buzzy), and standard care on pain management during venipuncture in children aged 6-12 years.
This study aims to test the effectiveness of virtual reality (VR) as a non-pharmaceutical intervention to reduce pain and anxiety in children undergoing painful procedures in Phlebotomy, Radiology, Infusion, Orthopedics, Gastroenterology, and Immunology, amongst others, at CHLA, as measured by self- and proxy-report. Examples of the painful procedures include IV sticks, cast removals, allergy testing, and anorectal manometries.
The purpose of this study was to examine the Veinplicity Device as an adjunctive IV cannulation tool in subjects with a history of difficult to access veins. The Veinplicity Device is intended to improve venous access rates in compromised patients by taking advantage of the increased circulation that results from provoked muscle stimulation. The study collected information about the device, intravenous access, user and patient perceptions for IV access, and any device or procedural complications or other adverse events. Device use was examined with patients in both a prone and upright position.
Synera, which is a heated topical patch containing both lidocaine and tetracaine, is intended to reduce the pain associated with venipuncture and superficial dermatologic procedures by numbing the skin. This study will test the effectiveness of the Synera lidocaine/tetracaine patch when administered for 30 ± 5 minutes to provide dermal anesthesia in adult oncology patients undergoing venipuncture as part of their care, for treatment or diagnostics (laboratory or imaging). Compared to the use of the placebo patch, this study hypothesizes that the difference of 1 cm on the 0-10 visual analogue scale (VAS) will be observed 30 minutes after the use of the Synera patch. Pain intensity will be assessed by a 0-10 VAS
The purpose of this study is to determine whether co-application of a functional microarray of needles (FMA) speeds the rate at which topical anesthesia is provided. A secondary goal is to determine whether the depth of anesthesia is enhanced.
Hypothesis: The first attempt success rate for peripheral IV insertion for children with difficult IV access (difficult IV access [DIVA] score ≥ 4) by nurses using the VeinViewer guided technique is better than conventional method of IV placement. Specific Aims: 1. To investigate if use of the VeinViewer can improve the success of peripheral IV placement in children with difficult IV access 2. To validate the DIVA score Design: Prospective randomized controlled trial/Convenience sample Subjects: Children (0-18) presenting to the emergency department who require an IV as determined by examining physician and with a DIVA score ≥ 3 during times when VeinViewer machine is available and a VeinViewer trained participating nurse is on duty. Variables: Outcome Variables: First IV attempt success rate Predictor Variables: IV technique used, other potential modifiers (age, weight, height, skin shade, indication for IV, history of prematurity and, vein visibility/palpability after tourniquet) Methods: Subjects who meet inclusion criteria will be randomized to either conventional IV technique or VeinViewer guided technique. The nurse will attempt the IV depending on the randomization. Success or failure on first IV attempt will be recorded. If unsuccessful, other attempts will be tried until a successful IV is placed or the physician decides to give an alternative therapy that does not need IV access. Statistics: A chi square test will be used to compare the proportion of subjects with successful first attempt IV placement using the VeinViewer technique to that using the conventional method with 95% confidence interval. We, the researchers, will look at the median number of attempts to place an IV in each of the groups. Logistic regression will be performed to test for independent associations. Information collected during the study will also be used for validation of the DIVA score. Risks: No extra risks are expected above that of receiving a standard IV. The standard risk of bleeding, bruising, pain, and infection will be possible regardless of technique used. The VeinViewer does not expose the patient the ionizing radiation. The use of the VeinViewer technique may increase the time need to place an IV in. Potential Benefits: With this study, we, the researchers, hope to improve the success rate of children with difficult IV placement in the Emergency Department.
