Major microvascular blood flow alterations have been documented in patients with severe sepsis. It was also demonstrated that the microcirculation improved in survivors of septic shock but failed to do so in patients dying from acute circulatory failure or with multiple organ failure after shock resolution. Early, effective fluid resuscitation is a key component in the management of patients with severe sepsis and septic shock with the goal of improving tissue perfusion. The best fluid in this early resuscitation phase has been and still is under debate. The aim of this study is to evaluate the effect of Three different Fluids(Albumin 5%, Normal Saline, HES 130 kD) on microcirculation in severe sepsis/septic shock patients using Sidestream Dark Field (SDF) Microscopy and Near-Infrared Spectroscopy (NIRS) analysis.
The impact of lactate guided therapy on septic shock has not been extensively investigated, however the goal directed therapy has been used for years. The investigators aim was to test the hypothesis that lactate directed hemodynamic therapy is associated with improving the outcome of patients with septic shock by comparing different goal directed strategies which have been commonly recommended clinically. In this multicenter, randomized trial, the investigators assigned patients with septic shock to three groups: Patients were treated with hemodynamic therapy directed either by conventional parameters treatment (control group), or central venous oxygen saturation (ScvO2), or blood lactate respectively in each group. The primary outcome was the rate of death at 28 days after randomization and in-hospital mortality; secondary end points include hemodynamic states, time to goal-achievement.
Severe sepsis/septic shock is a serious condition associated with high mortality rate. Hydrocortisone has been recommended as a useful treatment to decrease mortality in hemodynamically unstable septic shock patients, not response to fluid and moderate dose of vasopressor. During the progression of severe sepsis/septic shock, multi-organ dysfunction can develop. Acute lung injury (ALI) and its more severe form, acute respiratory syndrome (ARDS) is one of the common organ dysfunction associated with septic shock. Information from a meta-analysis suggested that moderate dose of hydrocortisone may improve the ARDS patients' outcome. Whether hydrocortisone can effectively prevent disease progression and death in severe sepsis/septic shock patients who complicated with ALI/ARDS has not been proven.
The investigators hypothesize that dobutamine is able to revert negative redistribution of flow by inducing a selective vasodilatory effect on hypoperfused territories, particularly at the sublingual and gastric mucosa, and at the peripheral tissues. The investigators designed a randomized, cross-over, placebo-controlled study looking at the acute physiologic effects of 5 mcg/kg/min fixed-dose of dobutamine on cardiac function, microcirculation, gastric mucosal, hepatosplanchnic, and peripheral perfusion in septic shock patients.
Septic shock and multi-organ failure are among the most frequent causes of death in the ICU. Patients with septic shock require early implementation of hemodynamic therapy to keep the duration of shock state and with it microcirculatory disturbances as short as possible. In the septic shock guidelines by the american association SCCM the diagnosis of volume status is based on filling pressures, like CVP. Some studies show, that the CVP depends not only on the intravascular volume, but also on the right ventricular compliance, pulmonary vascular resistance as well as intrathoracic pressure. The aim of the Study is to evaluate if the duration of septic shock can be reduced through algorithm driven volume therapy orientated to thermodilution based volume parameters (GEDI and ELWI)
MP4OX is a novel oxygen therapeutic agent being developed as an ischemic rescue therapy to enhance perfusion and oxygenation of tissues at risk during hemorrhagic shock. MP4OX is a pegylated hemoglobin-based colloid. Due to its molecular size and unique oxygen dissociation characteristics, MP4OX targets delivery of oxygen to ischemic tissues. This study will evaluate the safety and efficacy of MP4OX treatment in trauma patients suffering from lactic acidosis due to severe hemorrhagic shock. The study hypothesis is that MP4OX will reverse the lactic acidosis by enhancing perfusion and oxygenation of ischemic tissues and thereby prevent and reduce the duration of organ failure and improve outcome in these patients.
The purpose of this study is investigate the effects on systemic hemodynamics and organ function of esmolol when used to maintain heart rate below a predefined threshold in patients with septic shock.
A prognostic score was proposed by the investigative team to predict death at 1 month. This score is based on certain biological markers, scored under emergency conditions in the first 24 hours of routine clinical practice management for septic shock. The main objective of this multicenter study is to validate the performance of the score in terms of area under the ROC curve and negative predictive value.
The purpose of this randomized, comparative, open and multi-centre study is to show that two sessions of hemoperfusion with Toraymyxin performed within maximum 36 hours after the surgery of a peritonitis by hollow organ perforation reduce the mortality in patients suffering from septic shock.
