The role of intensive insulin therapy in patients with severe sepsis is uncertain. Fluid resuscitation improves survival among septic shock, but evidence lacking to support the choice either crystalloids or colloids.

Extracorporeal life support (ECLS) is increasingly used in the treatment of infarct-related cardiogenic shock despite a lack evidence regarding its effect on mortality. Download PDF Research Summary. In this multicenter trial, patients with acute myocardial infarction complicated by for whom early revascularization was planned were randomly assigned to receive ECLS plus usual medical (ECLS group) or alone (control group). The primary outcome death from any cause at 30 days. Safety outcomes...

Background . Sound data about the prevalence of acute renal failure (ARF) among patients with severe sepsis and septic shock are lacking. Further, it is not known whether ARF an independent risk factor for mortality in or merely indicator disease severity.

Early appropriate antimicrobial therapy leads to lower mortality rates associated with severe sepsis. The role of empirical combination comprising at least 2 antibiotics different mechanisms remains controversial.To compare the effect moxifloxacin and meropenem alone on sepsis-related organ dysfunction.A randomized, open-label, parallel-group trial 600 patients who fulfilled criteria for sepsis or septic shock (n = 298 monotherapy n 302 therapy). was performed 44 intensive care units in...

Background —Impaired endothelium-dependent vasodilation is an early sign of atherosclerosis in hypercholesterolemic patients. We hypothesized that lipid-lowering therapy can improve endothelial function and this effect mainly mediated by increased bioavailability nitric oxide (NO). Methods Results —In a randomized, double-blind, placebo-controlled trial, we studied 29 patients (age, 50±12 years) with hypercholesterolemia (LDL cholesterol ≥160 mg/dL) randomly assigned to receive either...

Background Hypercholesterolemia, a risk factor for cardiovascular disease, is associated with inflammation and hypercoagulability. Both can be mediated by the CD40 system. This study investigated whether system upregulated in patients moderate hypercholesterolemia it influenced therapy hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase inhibitor. Methods Results Fifteen 15 healthy control subjects were investigated. CD154 P-selectin analyzed on platelets was monocytes before under statin...

Extracorporeal life support (ECLS) has been increasingly used in the treatment of severe infarct-related cardiogenic shock last decade. The randomised ECLS-SHOCK trial demonstrated no benefit early routine use on 30-day all-cause death. We herein present mid-term results. At 1-year follow-up, there were significant differences or cardiovascular mortality, neurologic outcome, recurrent myocardial infarction, repeat revascularisation and rehospitalisations for heart failure between ECLS usual...

Background. Parameters of splanchnic regional perfusion, like intramucosal pH (pHi) and pCO2 (pCO2i), may predict outcome in septic shock patients. Continuous venovenous haemofiltration (CVVH) has been considered beneficial haemodynamically unstable In a prospective, randomized, clinical study, we investigated whether CVVH, comparison to intermittent haemodialysis (IHD), is able improve perfusion critically ill

This paper provides an endorsement of the KDIGO guideline on acute kidney injury; more specifically, part that concerns renal replacement therapy. New evidence has emerged since publication was taken into account, and is commented from a European perspective. Advice given when to start stop therapy in which modalities should be preferentially applied, conditions; how gain access circulation; measure adequacy; dose can recommended.

Abstract Introduction Lung-protective ventilation in patients with ARDS and multiorgan failure, including renal is often paralleled a combined respiratory metabolic acidosis. We assessed the effectiveness of hollow-fiber gas exchanger integrated into conventional renal-replacement circuit on CO 2 removal, acidosis, hemodynamics. Methods In ten ventilated critically ill AKI undergoing renal- respiratory-replacement therapy, effects low-flow removal acidosis compensation were tested by using...
