Fasting does not appear to cause a change in preload of conscious volunteers nor does it significantly alter their position in the Frank-Starling curve, even with longer fasting times than usually recommended. Transaortic VTI variation with the passive leg raise manoeuvre is the most robust dynamic index (of those studied) to evaluate preload responsiveness in spontaneously breathing patients.

Central venous catheter placement is a relatively common procedure in current practice, but it is not devoid of risks. Utmost care must be taken to follow a correct technique, and only appropriately trained and/or supervised medical professionals should perform this invasive act. One of the possible complications, completely avoidable by appropriate care, is the intravascular loss of the guide wire during insertion, which is a potentially serious complication. We describe one such case.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
