Active clinical trials for "Shock"

Septic shock is a condition that is marked by severe infection causing hypotension requiring vasopressors to maintain adequate perfusion to vital organs. The Surviving Sepsis campaign, an international organization formed for the purpose of guiding the management of sepsis and septic shock, currently recommends norepinephrine as the first-choice vasopressor for septic shock. Phenylephrine, a vasopressor FDA-approved for use in septic shock, is recommended as an alternative vasopressor when septic shock is complicated by tachyarrhythmia to mitigate cardiac complications. This recommendation is based solely on experience with no scientific evidence to support this recommendation. The investigators will conduct an open-label randomized controlled trial (RCT) directly comparing phenylephrine and norepinephrine, two FDA-approved vasopressors that are both used in clinical practice for the management of septic shock. The investigators will perform this study with a population of patients that have septic shock to complete the following aims: Aim 1: Determine the incidence of tachyarrhythmias. Aim 2: Determine which vasopressor, phenylephrine or norepinephrine, is associated with a lower heart rate. Aim 3: Determine which vasopressor, phenylephrine or norepinephrine, is associated with a higher incidence of new tachyarrhythmias. Aim 4: Determine which vasopressor, phenylephrine or norepinephrine, is associated with less time in tachyarrhythmia. Aim 5: Determine which vasopressor, phenylephrine or norepinephrine, is associated with fewer complications, including cardiac complications. The investigators hypothesize that in this setting, phenylephrine will improve the management of septic shock when used as a "first choice" vasopressor by: Decreasing the mean heart rate Decreasing the incidence of new tachyarrhythmias Decreasing the amount of time spent in tachyarrhythmia for patients who develop new onset and recurrent tachyarrhythmias Decreasing the number of cardiac complications

This study is designed to improve the outcomes for patients suffering from severe sepsis and septic shock (SS/SS) by decreasing the time from first medical contact to antibiotic administration. This is a stepwise study that aims to demonstrate the ability of paramedics to accurately obtain blood cultures prior to hospital arrival, administer a broad spectrum antibiotic and initiate IV fluid resuscitation in patients meeting predefined criteria for SS/SS.

The objective of this study is to determine the feasibility of conducting a large scale randomized controlled trial comparing standard and renally adjusted dosage of antibiotics in the septic shock patients with acute renal dysfunction. We will use Piperacillin as the prototype antibiotic in our study.

Early intervention in the treatment of septic shock, including early goal-directed therapy (EGDT) in the first 6 hours of disease presentation, has been shown to significantly decrease mortality. However, this approach requires invasive hemodynamic monitoring, thus limiting its widespread application in the emergency department setting. A minimally invasive protocol utilizing esophageal Doppler monitoring (EDM) may be of benefit and practical if it is shown to result in similar outcome as EGDT.

Hypothesis: We hypothesize that resuscitation regimens which minimize the total volume of resuscitation fluid, while restoring organ perfusion, will lead to lower morbidity and mortality in critically ill patients following trauma.

Evaluate the implementation of a standardized mobile resuscitation model to manage SWOT within a large acute care hospital setting.

Septic shock is in critically ill patients is a condition associated with a high rate of organ failure and hereto attributable mortality ~45-55% Hypothesis: Mild Induced Hypothermia reduces the mortality of critically ill patients with septic shock by reducing organ metabolism, counteracting on microcirculatory thrombosis, genetically downregulating tissue apoptosis and by reducing bacterial growth rate and toxin production.

The study objective is to clarify whether the application of CPFA (coupled plasma-filtration adsorption) in addition to the current clinical practice is able to reduce mortality and prevent organ failures in septic shock patients in intensive care unit (ICU).

A randomized controlled clinical trial to evaluate whether a passive leg raising test to guide fluid therapy of patients with septic shock can reduce fluid balance and weight gain. Patients will be treated according to an algorithm in which the indexed stroke volume (stroke volume related to body surface area) and mean arterial pressure will guide the timing and amount of fluid and the use of inotropic and vasoactive support. Patients will be randomized to either an intervention group in which a passive leg raising test will be made prior to any decision for fluid administration or to a control group where this test is not performed and fluid administration is carried out according to standard of care at the department. Hypothesis: A passive leg raising test, will reduce weight gain by day 3 by 30%.

In this pilot randomized prospective controlled trial the investigators intend to compare the use of a nutritional therapy based on caloric intake determined by indirect calorimetry and high protein intake with nutritional regimen based on 25 Kcal / kg / day and protein intake usually recommended for critically ill patients (1.4 to 1.5 grams / kg / day of protein).
