View clinical trials related to Arterial Catheterization.
Filter by:Conventionally, long-axis in-plane (LA-IP), short-axis out-of-plane (SA-OOP) and dynamic needle tip positioning based on SA-OOP views are commonly used method to image the target vessel during cannulation under US guidance. A modified SA-OOP that add developing line on the ultrasonic probe improve the success rate of cannula insertion into the radial artery on the first attempt.
Arterial cannulation is indicated in several clinical settings: high-risk surgery, respiratory failure, circulatory failure. The possible anatomical sites of cannulation are: a.radialis, a.brachialis, a. femoralis. However, the most reported complications in preschool-aged children are associated with femoral and brachial arteries. Therefore, alternative cannulation sites are being searched as ulnar artery, tibial posterior artery.
Arterial catheterization in small children is challenging, even for experienced anesthesiologists. For successful arterial catheterization, the arterial diameter, cross-sectional area, and depth from the skin surface are important considerations, especially in pediatric patients. THe investigators examined the posterior tibial artery (PTA) and dorsalis pedis artery (DPA) using ultrasound (US) to find a reasonable alternative arterial cannulation site to the radial artery (RA) in pediatric patients.
Investigators designed a prospective randomized controlled study to compare the long-axis/in-plane and short-axis/out-of-plane methods during the ultrasound-guided arterial catheterization in pediatric patients younger than 5 years old.
Arterial catheterization is painful and is associated with patient stress and anxiety. Analgesia is usually provided by subcutaneous injection of local anesthetic. An alternative is topical anaesthesia, such as Rapydan which is a novel topical anesthetic patch containing 70 mg each of lidocaine and tetracaine. We therefore tested the hypothesis that Rapydan patch analgesia is non-inferior to subcutaneous local anesthetic.
