British Journal of Anaesthesia Peer-Reviewed Clinical Study
384 subjects from diverse subgroups including those associated with decreased vein visibility such as infants, elderly, dark skin, obese and morbidly obese patients.
- An average of 3.3 additional suitable IV sites were observed with Veinsite when compared to conventional method (95% confidence interval)
- Especially difficult cases were identified and defined as subjects where conventional method detected no cannulation site or only one
- Veinsite increased the detection of possible IV cannulation sites in 97% of these especially difficult cases – including 1.7 additional vein sites for the infant group (89% increase) and 3.7 additional vein sites for African-Americans (80% increase)
- Obese subjects’ vein visibility was also markedly improved by 4.0 (82% increase) and morbidly obese patients improved by 3.0 (83% increase)
Veinsite Clinical Abstracts presented to the 2015 American Society of Anesthesiology Conference
Jean‐Pierre Monrigal, M.D. (Department of Anesthesiology, Centre Hospitalier Universitaire, ANGERS, France) presented two abstracts at the 2015 annual meeting of the American Society of Anesthesiology in San Diego, CA.: “Learning to use a Near Infrared System (Veinsite® Vuetek®scientific) to Improve Peripheral Intravenous Cannulation in Children” and “Interest of a Near Infrared Device (Veinsite® Vuetek® Scientific) to Support Intravenous Cannulation in Children”.
“Interest of a Near Infrared Device (Veinsite® Vuetek® Scientific) to Support Intravenous Cannulation in Children”: thirteen operators (8 anesthesiologists and 5 anesthesiology nurses) working in pediatric anesthesia and the intensive care unit (PICU) used the Veinsite® for the first time. Each operator had to successfully cannulate 6 veins on children (of varying age, sex ratio, weight, height, BMI, and Fitzpatrick classification in 6 phototypes) who were undergoing surgery. At the conclusion of the study, each operator answered a questionnaire using a Likert scale and evaluated the procedure for ergonomy, vision, gesture, locating the vein, puncture, cannulation, and training (enough or not):
“Learning to use a Near Infrared System (Veinsite® Vuetek® Scientific) to Improve Peripheral Intravenous Cannulation in Children”: the contribution of Veinsite regarding cannulation of peripheral veins in the pediatric operating room (OR) and pediatric intensive care unit (PICU) was evaluated. Eight senior pediatric anesthesiologists and intensivists trained with Veinsite (training was defined as 6 successful cannulations) used it:
- In the OR for all children undergoing surgery and requiring an IV line. A first attempt was performed classically by the operator. In case of failure, the Veinsite was used.
- For children in PICU, oncology, surgery, and emergency departments who required an IV line, the first attempts were performed classically by the ward nurses. If ward nurses were unsuccessful, the PICU nurse made a classical attempt to start the IV line, and if unsuccessful, the senior anesthesiologist used Veinsite to start the IV line.
