Filter by:The purpose of this study is to verify the accuracy and applicability of predictors of fluid administration efficacy in hypotensive critically ill patients.
The goal of this retrospective study is to describe emergency relevant illnesses occurring in airline passengers.
Patients with severe infection can develop very low blood pressure. There are many mechanisms leading to this, and one of them appears to involve a hormone called vasopressin. In children as compared to adults, the mechanism and response to low blood pressure are different for reasons that are not clear. One possibility is the difference in the production and/or response to vasopressin. Vasopressin has become part of the treatment of children with low blood pressure in the setting of severe infection, when other treatment has failed, but its use is on the basis of animal and adult studies. The exact timing and dose is uncertain. In this research study, the patients will receive standard treatment for sepsis and septic shock, and the investigators will measure the blood levels of vasopressin and a related compound called copeptin (both are required to understand the mechanism of control involved). Blood will need to be taken from patients without any sepsis so as to be able to compare the values in health and in sickness. The patient groups the investigators have chosen for this are those children who will have blood taken anyway as part of their routine care. The aim of this study is to develop an understanding of the body's hormonal response (with respect to vasopressin) to severe infection in children. The long-term aim is to improve the care of critically ill children with severe infection by using the most appropriate dose of vasopressin at the most appropriate time.
Septic shock is a major cause of mortality and morbidity worldwide. Serotonin (5-HT) is released by activated platelets into the circulation, and is mediator of endothelial dysfunction. 5-HT metabolism is known in immune system via specific 5-HT receptor, also in effects on the peripheral nervous system. Kinetic of 5-HT, tryptophan, kynurenine, MAO activity and IDO activity in human septic shock was never investigated.
New single use laryngoscope metal blades are available for intubation. This type of blade is safer than the reusable ones concerning the interhuman cross infection risk. No clinical studies have compared the two types of blades in the emergency context. The primary aim of this study is to demonstrate that single use blades are as efficient as the reusable ones concerning intubation conditions.
The present study was conducted as a prospective, randomized, controlled study to compare: - the effects of norepinephrine and phenylephrine on systemic and regional hemodynamics in patients with catecholamine-dependent septic shock - to test the hypothesis that norepinephrine may likewise better preserve hepatosplanchnic perfusion versus phenylephrine in patients suffering from septic shock
Septic shock is a frequent and severe complication in cirrhosis. Current mortality rate ranges between 50 and 80% of cases. Refractory shock, hepatorenal failure and variceal bleeding are the main causes of death of these patients. Terlipressin administration could prevent these complications and improve survival in this setting. Aim: To evaluate the effects of terlipressin administration on hospital survival in cirrhotic patients with severe sepsis or septic shock. Methods: Prospective, open labelled, controlled trial evaluating 72 cirrhotic patients with severe sepsis or septic shock who will be randomized to receive terlipressin plus alpha-adrenergic drugs or only alpha-adrenergic drugs at shock diagnosis. Patients will be submitted to continuous systemic hemodynamic monitoring (S. Ganz catheter or Vigileo). Changes in vasoactive systems and cytokines levels will be also evaluated.
This study aims at comparing the efficacy and safety of recombinant human activated protein C to that of low dose of corticosteroids and at investigating the interaction between these drugs in the management of septic shock
Pyruvate is an intermediate of energy metabolism and was shown to possess pronounced positive inotropic effects in vitro and in vivo without altering myocardial oxygen consumption. Moreover, it was shown that the effects of beta-adrenergic stimulation were potentiated. Thus, it might be possible to save catecholamines in patients with severe heart failure or cardiogenic shock. This study was designed to test the hemodynamic effects of pyruvate administered into a coronary artery in addition to intra-aortic balloon pump counterpulsation in patients with severe heart failure or in patients with acute myocardial infarction and cardiogenic shock after having performed percutaneous coronary intervention. A pronounced improvement in hemodynamics is expected to occur.
We are performing a prospective, randomized, controlled trial of dopamine versus norepinephrine for septic shock. The trial will enroll patients with suspected or documented site of infection and having 2 out of the three SIRS criteria. Patients will also be receiving standard of care, early-goal directed therapy including but not limited to fluid resuscitation, appropriate and early antibiotics, source control and evaluation for drotrecogin alpha where deemed appropriate, while being supported for septic shock.
