Early preload adaptation in septic shock? A transesophageal echocardiographic study.
BACKGROUND An accepted concept in septic shock is that preload adaptation by acute left ventricular dilatation, when occurring spontaneously or with the aid of volume loading, permits maintenance of an adequate cardiac output, leading to final recovery. From a physiologic point of view, this concept appears debatable because a normal pericardium exerts a restraining action on a normal heart. ...
متن کاملOptimization of Preload in Severe Sepsis and Septic Shock
In sepsis both under- and overresuscitation are associated with increased morbidity and mortality. Moreover, sepsis can be complicated by myocardial dysfunction, and only half of the critically ill patients exhibit preload responsiveness. It is of paramount importance to accurately, safely, and rapidly determine and optimize preload during resuscitation. Traditional methods of determining prelo...
متن کاملPreload dependence indices to titrate volume expansion during septic shock: a randomized controlled trial
INTRODUCTION In septic shock, pulse pressure or cardiac output variation during passive leg raising are preload dependence indices reliable at predicting fluid responsiveness. Therefore, they may help to identify those patients who need intravascular volume expansion, while avoiding unnecessary fluid administration in the other patients. However, whether their use improves septic shock prognosi...
متن کاملThe role of echocardiography in hemodynamic assessment of septic shock.
Echocardiography is a rapid, noninvasive, comprehensive cardiac assessment option for patients presenting with hemodynamic instability. In patients with septic shock, echocardiography can be used to guide fluid therapy by measuring collapsibility of the inferior vena cava. Sepsis-induced myocardial dysfunction can be diagnosed, and responses to therapy can be monitored with echo. Patients with ...
