Active clinical trials for "Shock"

The high ratio of "central venous to arterial carbon dioxide" to "arterial to central venous oxygen content " is associated with elevated lactate in patients with septic shock. So, the aim of the present study is to evaluate the ratio of "central venous-to-arterial CO2 tension or content" to "arterial-to-venous O2 content'' as an indicator of anaerobic metabolism in septic shock.

Septic shock remains the dominant cause of death in ICU's of the developed world with approximately 400,000 cases annually in the US and another 20,000 annually in Canada. While many retrospective and prospective reviews of septic shock patients have been undertaken worldwide, many key questions remain unanswered. These questions include the true incidence, associated morbidity and mortality of septic shock in North America, key factors associated with successful management and markers suggesting a high probability of a complicated clinical course. Part of the reason for the persistence of these questions, is the fact that previous and ongoing reviews of septic shock and severe sepsis have been either limited in number (typically <150) or biased by the need to be eligible for specific clinical trials (typically, non-eligible patients have not been followed and had data collected. We propose to examine specific questions within a temporally comprehensive cohort of septic shock patients by review of individual charts using a defined data-extraction template.

Patients with septic shock may have altered volume of distribution and metabolism of antibiotics which are crucial medications for treating infections. The aim of the study is to investigate the blood concentrations of Meropenem and Ciprofloxacin, two commonly used antibiotics, in patients with septic shock. The hypothesis is that standard dosing may produce insufficient levels of antibiotics in patients with septic shock.

The objective of the present study is to investigate accuracy of changes in cardiac output following passive leg raising as estimated by transthoracic ultrasound as method to predict fluid responsiveness and compare that to changes in cardiac output following PLR as estimated by calibrated pulse contour analysis as method to predict fluid responsiveness in patients with septic shock.

The goal is to observe that the incidence of acute kidney injury in patients who need fluid resuscitation when resuscitated with saline or acetated Ringer's sodium.

In order to identify the responding patients with vascular filling test, this research aims to compare the performance of the increased flow in the femoral artery to the performance of the blood pressure increase. The reference measurement will increase cardiac output measured by ultrasound.

Adults older than 18 years old, admitted to the ICU with a Severe Septic Shock, requiring Norepinephrine at more than 0.25mcg/kg/min, who have signed informed consent form, will be consecutively included, from december 2018 to december 2019. The primary goal is to look for risk factors associated with an increased in lactate clearance Secondary goals are the following: To look for risk factors associated with an increase risk of Hospital and ICU length of stay. To look for risk factors associated with an increase risk of Acute Kidney Injury. To look for risk factors associated with a decrease in days alive and free of Mechanical Ventilation, Vasopressors and Renal Replacement Therapy. To look for risk factors associated with a decrease in Ventilator-free days. To look for risk factors associated with a decrease in Vasopressor-free days. To look for risk factors associated with an increase risk of in-hospital mortality. To look for risk factors associated with an increase risk of Myocardial Infarction and myocardial injury. To look for risk factors associated with an increase risk of Acute Respiratory Distress Syndrome. To compare and validate different risk scores in our cohort.

Septic shock is the most severe form of a bacterial infection, affecting 24 million patients per year worldwide, with a high mortality (> 30%). Septic shock is defined by an acute circulatory failure, with low blood pressure and insufficient oxygen supply to organs. This circulatory failure is related to vascular damages, in which the endothelial vascular tissue is impaired by inflammatory mechanisms, with release of circulating endothelial cells in the blood. Therefore, modulating inflammation on the vascular endothelial tissue could be a therapeutic strategy, and the investigators focus on the role of the type I interferons on the endothelial tissue because of the demonstrated role of type I interferons during septic shock. Thus the investigators proceed to an observational study, in which the primary purpose will be to show a higher expression of type I interferon receptors on circulating endothelial cells in patients with septic shock compared to control subjects. Concerning secondary purposes, the investigators will record mortality at d3, d7 and d28, perform assays about types I, II and III interferons in plasma, and test anti-interferon on endothelial cells ex vivo

Research on health literacy among caregivers of children with IgE-mediated allergy at risk of anaphylaxis (life-threatening allergic reaction). Health literacy is a person's ability to understand health information so that they can maintain or improve their health and quality of life (of themself and children). The aim of the study is to test the general knowledge of anaphylaxis. Furthermore we test the extent to which caregivers consider themselves able to recognize and to treat anaphylaxis.

This clinical study adopts the design of cohort research, selects the sepsis shock patients admitted to our hospital ICU as the research object, takes the 28-day mortality rate as the outcome index, collects the baseline data of the patient, the severity of the disease, vital signs, the main infection site, the laboratory-related index, the treatment method and other data, screens out the risk factors affecting the sepsis shock 28-day mortality rate and constructs the prediction model accordingly, analyzes the prediction model with the subject's working characteristic curve (ROC). The recognition ability of the model is calculated by the area under the ROC curve (AUC) and the ability of the model to predict 28-day mortality with SOFA and APACHE II.
