Arterial Blood Gas (ABG) sampling is a common procedure in all hospitals worldwide. Often, ABG samples are obtain from inserting a needle into the radial artery at the wrist - this procedure is often painful and dreaded by patients. Therefore, some doctors use local anaesthetic but others argue that it makes the procedure more difficult and causes pain itself. The use of local anaesthetic costs approximately £1 per injection and when thousands of ABGs are performed per month, the cost is easily appreciable. However, there is no good research to guide clinicians in the use or omission of local anaesthetic for ABGs. This is the first randomised clinical trial to assess the efficacy of injected local anaesthetic on the perceived pain of radial artery puncture.
This study is a prospective, multi center, randomized, controlled study of the VasQ in arteriovenous fistulas. The VasQ constraints and directs the geometrical parameters of the fistula as well as the vascular diameter and gradient in the vicinity of the AV shunt. These geometrical constraints direct flow and influence hemodynamics, and hence minimize turbulence and promote laminar flow. The device is designed to improve short term maturation and long term patency of the fistula. The VasQ is a permanent implant intended for use as a subcutaneous arteriovenous conduit support for vascular access.
The objective of this study is to show VeinViewer® Vision is an effective vein visualization device for peripheral vascular access, pre-, during, and post access.
The objective of this study is to confirm and document that with the use of a FDA Class I exempt near infrared device, VeinViewer® Vision that is hands-free and can be used for healthy adult volunteers with varying skin types to assist in the improved visualization, it is possible to film, analyze and document PIV localized complications and venous flow and refill.
This project involves a pre- and post- airway management and vascular access simulation survey. The purpose of the study is to assess the perceived effectiveness of the simulation course on the performance of medical students enrolling in the Anesthesiology rotation during their third and fourth year of medical education.
The purpose of this study is to compare the use of fluoroscopic guidance, (a commonly used X-ray technique), with the traditional approach, (where the doctors feel for the strongest pulse), to obtain access to the blood vessel in the groin. These two methods are being compared to assess which is faster, safer and more often allows your physician to use an "arterial closure device," a small suture or plug applied at the end of the angiogram where the needle enters your blood vessel if he/she chooses.
