adrenalin AND sepsis

Polymyxin B-immobilized fiber column direct hemoperfusion (PMX-DHP) therapy is widely used for the treatment of severe sepsis and septic shock, and is generally performed for 2 h. Although previous studies demonstrated the efficacy of PMX-DHP therapy, it currently remains unclear whether its optimal duration is 2 h. This retrospective study analyzed 37 patients with septic shock who showed a poor clinical response to 2 h of PMX-DHP, and underwent a longer duration of this therapy. The mean duration of PMX-DHP therapy was 15...

We have recently reported that pre-treatment, but not the post-treatment with atorvastatin showed survival benefit and improved hemodynamic functions in cecal ligation and puncture (CLP) model of sepsis in mice. Here we examined whether combined treatment with atorvastatin and imipenem after onset of sepsis can prolong survival and improve vascular functions. At 6 and 18h after sepsis induction, treatment with atorvastatin plus imipenem, atorvastatin or imipenem alone or placebo was initiated. Ex vivo experiments were done on mouse aorta to examine the vascular reactivity to nor-adrenaline and acetylcholine and mRNA expressions of α1D AR, GRK2 and eNOS...

PURPOSE: The purpose of this study is to investigate potential associations between sympathoadrenal activation and/or vasopressor/inotropic therapy and endothelial activation, damage, and coagulopathy in septic patients. MATERIALS AND METHODS: Septic patients included in the Scandinavian Starch for Severe Sepsis/Septic Shock trial who were expected not to receive catecholamines at screening preintervention (baseline) and had baseline blood sampled. Clinical, outcome data, and measurements of plasma concentration (p-) biomarkers reflecting sympathoadrenal activation, endothelial activation and damage, natural anticoagulation, fibrinolysis, cell damage, and platelet activation...

BACKGROUND: Maintaining threshold values of cardiac output (CO) and systemic vascular resistance (SVR) when used as part of the American College of Critical Care Medicine (ACCM) haemodynamic protocol improves the outcomes in paediatric septic shock. OBJECTIVE: We observed the evolution of CO and SVR during the intensive care admission of children with fluid-refractory septic shock and report this together with the eventual outcomes. DESIGN: Prospective observational study...

PURPOSE: The aim of this study was to investigate associations between circulating catecholamines, endothelial damage, and coagulopathy in experimental human endotoxemia and septic patients. MATERIALS AND METHODS: Nine healthy male volunteers undergoing endotoxemia (4-hour 0.5 ng/kg/hour infusion of E. coli lipopolysaccharide, blood sampling at 0, 4, and 6 hours) and 20 patients with severe sepsis. Analysis of plasma biomarkers (adrenaline, noradrenaline, thrombomodulin, syndecan-1, soluble vascular endothelial cadherin, histone-complexed DNA fragments, soluble CD40 ligand [sCD40L], protein C, tissue-type plasminogen activator, plasminogen activator inhibitor 1) and routine coagulation tests...

BACKGROUND: In this report, we share our experience with left ventricular assist device (LVAD) implantation in cases with a left ventricular (LV) thrombus. METHOD: Over the 3 years, more than 100 end-stage heart failure cases have been treated with LVAD implantation in our center, including 6 patients with a LV thrombus. Three were detected using preoperative transthoracic echocardiography. Fifty percent of the patients had dilated cardiomyopathy and the remaining cases had an ischemic etiology...

Cardiovascular failure in sepsis involves a combination of hypovolemia, decreased vascular tone, myocardial depression and microcirculatory alterations. Fluids represent the first line therapeutic intervention, with controversy regarding the type of fluid. Recent data indicate that albumin is safe and might even be beneficial in specific subgroups. Starches may be an alternative, although concerns exist on potential detrimental effects on renal function of old generation starches. Trials testing new generation starches are ongoing...

Severe sepsis is a life-threatening disease that causes major morbidity and mortality. Catecholamines and glucocorticoids often have been used for the treatment of sepsis. Several recent studies have suggested a potential role of IL-17 during the development and progression of sepsis in small animal models. In this study, the cross-talk of catecholamines and glucocorticoids with members of the IL-17 family was investigated during sepsis in C57BL/6 mice. The concentrations in plasma of IL-17A, IL-17F, and the IL-17AF heterodimer all were increased greatly in mice after endotoxemia or cecal ligation and puncture as compared with sham mice...

A 71-year-old valvular patient with cardiac arrhythmia, low ejection fraction, administered angiotensin converting enzyme inhibitor underwent aortic and mitral valvular replacement. Starting during normothermic cardiopulmonary bypass (CPB), hypotension occurred, refractory to phenylephrine, noradrenaline, terlipressin, hydrocortisone and dexchlorpheniramine. After 3 hr of CPB biventricular hyperkinesia, severe hypotension and metabolic acidosis persisted despite volume loading, sodium bicarbonate, adrenaline infusion and intraaortic conterpulsation...

BACKGROUND: The level of soluble vascular endothelial growth factor receptor 1 (sVEGFR1) is increased in sepsis and strongly associated with disease severity and mortality. Endothelial activation and damage contribute to both sepsis and trauma pathology. Therefore, this study measured sVEGFR1 levels in trauma patients upon hospital admission hypothesizing that sVEGFR1 would increase with higher injury severity and predict a poor outcome. METHODS: Prospective observational study of 80 trauma patients admitted to a Level I Trauma Centre...

A few modern concepts of anesthesiological and resuscitation care during complicated surgical interventions are considered with special reference to multimodal anesthesia as a principal tool for the protection of the patient from a surgical trauma based on the rational combination of three-component epidural analgesia (ropivacaine, fentanyl, and adrenalin) with sevoflurane inhalation narcosis and extention of the same epidural analgesia to the early postoperative period. The basic principles of infusion-transfusion therapy for the treatment of massive intraoperative blood loss ensuring its tolerability by the patient are discussed...

A case of 7-day-old male neonate with cefotaxime-induced near-fatal anaphylaxis is being reported. Child was started on intravenous cefotaxime on day 3 of life in view of early-onset sepsis with pneumonia, following which there was clinical improvement. Child was then shifted out of intensive care to general ward for completion of antibiotic course. One day prior to the planned discharge, child suddenly developed poor sensorium, flaccidity, apnea, and cyanosis within seconds of receiving intravenous cefotaxime and was found to have bradypnea with bradycardia...

INTRODUCTION: Azoles, and specifically itraconazole, are often prescribed for the treatment of fungal diseases or empirically for persistent sepsis in patients who are neutropenic or in intensive care. Occasional cardiovascular adverse events have been associated with itraconazole use, and are usually attributed to the interaction of itraconazole with cisapride, terfenadine or digoxin. Its interaction with amiodarone has not been previously described. CASE PRESENTATION: A 65-year-old Caucasian man was admitted to the Intensive Care Unit at our facility for an extensive ischemic stroke associated with atrial fibrillation...

OBJECTIVE: To investigate the effects of hepatic radiofrequency ablation (RFA) in patients with malignant liver disease with respect to inflammation activation and stress response. MATERIALS AND METHODS: In an observational trial, we investigated the physiologic parameters of 17 patients (20 interventions) who underwent percutaneous RFA under general anesthesia after applying total intravenous anesthesia. TNFα, IL-6, IL-8, IL-10, adrenaline and noradrenaline, liver enzymes, lactate and creatine kinase were determined pre-interventionally after induction of anesthesia (T1), 90 minutes after initiation of RFA (T2), immediately after the conclusion of the procedure (T3), and 24 hours after the procedure (T4)...

Severe sepsis and multiple organ distress syndrome remain a diagnostic and therapeutic challenge for intensive therapy. Platelet activating factor forms a bridge between inflammation and clot formation. Our study surveys the effect of severe sepsis on platelet function and focuses on spontaneous aggregation in severely ill patients. Daily arterial blood samples were collected from 45 patients (average age of 60.7 ± 13) for five consecutive days following admission and 30 healthy controls. Platelet aggregation was measured using adrenaline (ADR), adenosine diphosphate (ADP), collagen (COL) and normal saline (SAL)...
