【 摘 要 】

Peripheral venous access is a routine procedure in emergency and critical care areas. However, not allprocedures are successful due to altered venous anatomy, varied patient characteristics and blind natureof procedure. Sometimes, this seemingly easy procedure may become difficult, time-consuming, andexasperating. Needle punctures in the process to obtain peripheral venous access can lead to inadvertentarterial punctures, pain, extravasation, localized swelling and patient discomfort. Use of ultrasoundimproves the probability of achieving venous access and decreases the rate of unwanted central lineinsertions and associated complications. This review will present latest evidence into the use of ultrasoundguided peripheral venous access and briefly describe the indications, method and contraindications ofthis technique in emergency and critical care settings.
