Use of the Ultrasound Technique as Compared to the Standard Technique for the Improvement of Venous Cannulation in Patients with Difficult Access.

(1) Objective. We aimed to demonstrate that the use of the ultrasound-guided technique facilitates peripheral venous cannulation as compared to the standard technique in patients with difficult access at emergency services. (2) Method.

[None invasive and minimally invasive hemodynamic monitoring in critically ill patients in the emergency department].

Noninvasive and minimally invasive hemodynamic monitoring systems are used increasingly in emergency departments to provide adequate tissue oxygenation in critically ill patients. Such monitoring assists in the differential diagnosis of shock, the optimization of treatment and assessment of its effects, and the prevention of complications during care. Recent years have seen the development of noninvasive monitors that measure cardiac output continuously by means of electrodes applied to the skin or spectrophotometric sensors.
