Filter by:Early and adequate fluid resuscitation (< 6 hours) in patients with circulatory failure is essential but may exacerbate oedema, which may itself: 1) aggravate pulmonary lesions and prolong mechanical ventilation, 2) aggravate organ failure and 3) increase mortality notably in patients with acute renal failure. Improving fluid balance is considered crucial in the management of patients in septic shock, but the efficacy of the measures currently proposed (diuretics associated or not with albumin and/or dialysis) is controversial. The investigators hypothesize that a whole-body compression using a body bandage could reduce capillary leakage and thus lead to faster restoration of a normal transmural pressure gradient in postcapillary venules and improve venous return. This is the first study to evaluate mechanical compression using a body bandage to reduce oedema in septic shock. To do this, a whole-body compression will be set up within the 12 hours following admission. Water balance will be monitored daily throughout the duration of the compression and vital status of patients will be search at 7 days, 28 days and 90 days.
IgM-enriched immunoglobulins (IgGAM; Pentaglobin ® ) are new therapy for sepsis and septic shock since they support immune system especially in case of " immunoparalysis" . However IgGAM isn't commonly prescribed, few centres use it as routine in severe infections and there aren't any guidelines to determine how and when to use them. Microcirculatory dysfunction is a crucial aspect in the pathogenesis of sepsis-induced organ dysfunction, resulting in hypoperfusion and tissue hypoxia. Unpublished clinical data suggest a beneficial effect of IgGAM at microvascular level proved with near infrared spectroscopy and Vascular occlusion test (VOT). This study is a double blind phase II prospective randomised controlled trial that will include patients admitted to the Intensive Care Unit of the University Hospital "Ospedali Riuniti" of Ancona, after no more than 24 hours from development of severe sepsis or septic shoc. Patients will be randomized into two groups (treaties and controls): patients in group of the treaties will be submitted to infusion of IgGAM conjugate (Pentaglobin ®) at dosage of 250 mg/kg IV (5 mL/kg) per day (rate of 0.4 mL/kg/h), for 72 hours. The controls will receive equal amount of physiological NaCl solution (0.9%) as placebo. Neither the patient nor the staff nurses and MD will be aware of the group and of the treatment applied. IgGAM solutions or NaCl 0.9% will be provided by the hospital pharmacy in similar bags. The remaining treatments will not be changed in any way and will be at the discretion of the doctor who's in charge of the patient. All patients of the two groups will receive the optimal therapy for their conditions, according to good medical clinical practice (GMP), with appropriate antibiotic therapy, vasoactive and infusional therapy
A Prospective, Multi-Centre, Double-Blind, Randomized, Placebo-Controlled, Trial of Ulinastatin Treatment in Adult Patients with Sepsis and Septic Shock in China
The aim of this study is to investigate the effects milrinon and levosimandan on n heart function in septic cardiomyopathy and how norepinephrine affects the left and right ventricular function in patients with septick shock using pulmonary artery catheter, conventional and strain echocardiography.
The fact that sepsis disrupts immune system homeostasis by inducing an initial cytokine storm, that participates to occurrence of organ failures and early death, followed by a compensatory anti-inflammatory response leading to immunosuppression, is now well established. This immunomodulating response results in a higher risk of secondary infections and is associated to 2/3 of deaths related to septic shocks. Follow up of patients' immune status with time is crucial to guide therapy management. Objective of REALISM project is to demonstrate existence of this immunosuppression phase, by providing strong epidemiologic data for septic shock patients, but also by extension to other situations of inflammatory aggressions like severe severe trauma or burns, or major surgery. This project will provide tools to predict occurrence of secondary infections and guide patient management by comparing innovating immunomonitoring tools to reference tests non already adapted to a routine patient management. Targeted populations are adult patients hospitalized for septic shock, severe trauma (including severe burn) or major surgery and healthy volunteers, whom blood samples will serve to validate reference intervals of the two reference tests.
The current treatment regimen of patients with septic shock requires a sufficient hemodynamic support aiming to preserve tissue oxygen requirements and perfusion. Therefore, aggressive fluid challenge and vasopressor agents play a pivotal role. To increase total peripheral resistance and preserve organ perfusion, a continuous infusion of catecholamines is often needed. Because sepsis is usually associated with adrenergic receptor and post-receptor abnormalities, the efficacy of such treatment regimens often gradually decreases over time, thereby complicating hemodynamic support. Experimental evidence suggest that α-2 agonists increase pressor responsiveness following lipopolysaccharide administration. This study will assess the effects of the sedation with dexmedetomidine (α-2 agonist) on norepinephrine requirements in patients with septic shock.
Some studies have shown that antiplatelets agents could reduce organ dysfunction in septic shock in mice and human models. Platelets are actors in immunity and their activation can be complicated by tissue damage with vascular occlusions which can lead to organ dysfunction. Investigators can hypothesize an increase in platelet activation and in leukocyte-platelet aggregates in septic shock.
The investigators will conduct a prospective, single-center, randomized, double-blinded, controlled study to investigate the effect of early goal directed sedation on microcirculation in early septic shock patients.
The investigators preliminary study showed that dexmedetomidine might improve microcirculation in septic shock patients. To test this effect, the investigators will conduct double-blinded study.
The main objective of this study is to evaluate the effectiveness of the administration of a short acting beta-blocker in terms of effective increase in stroke volume (at least 15%) after 4 hours initiation of therapy in septic shock in patients with a hyperkinetic profile after 12-24 hours of care. This research seeks to demonstrate that the proportion of patients with an increase in the systolic ejection superior or equal to 15% (relative to baseline) at four hours is different between the two arms of the study: (1) an experimental arm where patients receive an esmolol infusion according to a predetermined procedure and (2) a control arm where patients receive a saline infusion according to a predetermined procedure.
