BACKGROUND AND OBJECTIVES Shock occurs when the circulatory system cannot maintain adequate cellular perfusion. If this condition is not reverted irreversible cellular injury establishes. Shock treatment has as its initial priority the fast and vigorous correction of mean arterial pressure and cardiac output to maintain life and avoid or lessen organic dysfunctions. Fluid challenge and vasoacti...

OBJECTIVE The aim of this trial was to determine whether Flotrac Vigileo™ (FV™) provides a reliable representation of the hemodynamic state of a cardiac surgical patient population when compared to pulmonary artery catheter (PAC) and echocardiography in the peril-operative period. DESIGN This was a prospective observational trial comparing perioperative hemodynamic states using transesophagea...

PURPOSE To describe the mechanisms of hemodynamic changes during off-pump coronary artery bypass graft surgery (OP-CABG). SOURCE Pertinent medical literature in the English and French languages was identified through a Medline computerized literature search and a manual search of selected articles, using off-pump coronary artery surgery, beating heart surgery, hemodynamic, and transesophageal...

INTRODUCTION Thoracic surgery frequently requires one-lung ventilation (OLV). Hemodynamic changes are significant during OLV and surgical manipulation and precise management of fluid administration is vital to postoperative recovery and surgical outcome. The FloTrac system, a minimally invasive hemodynamic monitoring device, with continuous cardiac output (CO) and stroke volume variation (SVV) ...

BACKGROUND Awareness during general anesthesia in different types of surgery is an important described adverse event. Bispectral (BIS) monitoring is one of the recent techniques proposed to monitor the depth of anesthesia. OBJECTIVES The present study tested the hypothesis that the awareness rate and changes in hemodynamic parameters within anesthesia would be lower in patients allocated to B...

Monitoring of vital functions is one of the most important and essential tools in the management of critically ill patients in the ICU. Today it is possible to detect and analyze a great variety of physiological signals by various noninvasive and invasive techniques. An intensivist should be able to select and perform the most appropriate monitoring method for the individual patient considering...

The monitoring of the cardiac output (CO) and other hemodynamic parameters, traditionally performed with the thermodilution method via a pulmonary artery catheter (PAC), is now increasingly done with the aid of less invasive and much easier to use devices. When used within the context of a hemodynamic optimization protocol, they can positively influence the outcome in both surgical and non-surg...

BACKGROUND Hemodynamic monitoring is frequently needed in ventilated patients with unstable hemodynamics after open-heart surgery. Novel miniaturized single-use transesophageal echocardiographic probe has been scarcely used in this clinical setting. CASE PRESENTATION A patient who underwent a scheduled open-heart surgery developed a ventilator-associated pneumonia and was referred to the inte...

C group Control group: without RA, using PEEP values bellow LIP (lower inflection point). The hemodynamic study (Heart rate, mean BP, PCP, PAP, CI), EVLW, and lactic acid, was made at basal time and at 15, 60, 180 and 360 minutes, after the provocation of ARDS. The catheters used for hemodynamic monitoring consisted in: venous catheters, arterial catheters and pulmonary artery catheter for dete...

In the ICU, an extensive array of variables from the hemodynamic monitoring display is routinely analyzed. However, the development of new display technologies is proceeding without adequate study of the monitoring tasks and behaviors of a primary user group--critical-care nurses. Semistructured interviews focusing on the cognitive aspects of the hemodynamic monitoring task were conducted with ...
