Filter by:A pilot randomized controlled trial to evaluate the efficacy and safety of Trendelenburg position in critically ill patients with hypotension, mainly patients with septic shock and post operative vasoplegia. The main aim is to assess whether Trendelenburg position can improve organ function through a reduction in the need of fluid infusion and dose of vasopressors. Patients will be screened for participation in the study and eventually randomized based on a balanced randomization scheme (1:1) to Trendelenburg position up to 72 hours after intensive care unit (ICU) admission or Semirecumbent position (standard of care).
Sepsis is an increasingly recognised burden to healthcare systems worldwide. Intravenous fluid therapy is a common first-line intervention recommended by international guidelines. Hyperoncotic preparations of human albumin solution are widely available, but their efficacy has yet to be proven. This randomised feasibility trial will test whether it is feasible to administer hyperoncotic albumin solutions as both fluid resuscitation and as a regular supplement in patients with early septic shock.
Septic shock is a major health problem. In the clinical practice guidelines of the Surviving Sepsis Campaign is recommended to add vasopressin (VP) or epinephrine in case of not reaching the goal of mean arterial pressure (MAP) although with a low level of evidence. This is a clinical trial with the purpose of comparing the efficacy and safety of norepinephrine (NE) plus placebo versus NE plus terlipressin (TP) in adult patients with septic shock and with a Sepsis related Organ Failure Assessment score (SOFA)> 4 points. The primary objective will be a combined end-point: reduction of organic dysfunction measured at 72 h by SOFA score and by the increase in ICU (Intensive care unit) -free days measured at 28 days.
This large real-world international prospective registry will provide a unique opportunity to comprehensively understand the contemporary management, clinical course and short as well as long-term outcomes of all Cardiogenic Shock (CS) patients cared for at four high volume dedicated shock care centers. As the first true North American multicenter CS collaborative with a uniform dedicated and comprehensive case report form, the high patient volumes and wide spectrum of clinical acuity seen at these institutions will provide valuable insight into the factors associated with adverse outcomes; and will serve as a blueprint for future clinical trial designs that may better inform clinical practice.
The ECMO-RESCUE study is a prospective, multicenter, non-randomized, cohort study. In this study, we aimed to assessed whether VA-ECMO treatment can improve the 30-day survival rate of patients with sepsis-induced refractory cardiogenic shock.
Rationale: Pump failure due to acute myocardial infarction (AMI) can lead to cardiogenic shock (CS): a state of low blood flow to end-organs with subsequent multi-organ failure that is associated with high mortality rated. The first line pharmacologic treatment strategy in CS is noradrenaline. This vasopressor drug is used to maintain adequate blood pressures. The assumption is that a mean arterial blood pressure (MAP) ≥ 65 mmHg will improve flow and thereby tissue perfusion of myocardium and other tissues (e.g. renal). However, there is no evidence that an increase in MAP, if achieved by noradrenaline, leads to greater end-organ blood flow and better outcomes. Objective: With this study the investigators aim to investigate the (cost-)effectiveness of reduced noradrenaline in patients with CS by using a lower MAP target of ≥ 55 mmHg, compared to ≥ 65 mmHg. The investigators hypothesize that reduced use of noradrenaline will improve overall survival and decrease renal failure requiring renal replacement therapy. Study design: Open label, randomized controlled multicenter trial Study population: Adults patients with CS due to AMI Intervention: Treatment strategy of reduced noradrenaline, by using a lower MAP target ( ≥ 55 mmHg). Main study endpoint: composite of all-cause mortality and severe renal failure leading to renal replacement therapy within 30-days after randomization.
The current guideline emphasizes fluid resuscitation as the mainstay of initial management for septic shock. Albumin has the oncotic activity to maintain intravascular volumes with additional beneficial properties in sepsis. Prior studies showed that the replacement of albumin might have survival advantages in patients with septic shock. The investigators aim to assess whether the early administration of albumin with crystalloid as initial fluid resuscitation improves survival in patients with septic shock compared to resuscitation without albumin.

Sepsis and septic shock are major causes of ICU admission worldwide. Despite recent advances in treatment, including targeted resuscitation and timely use of antimicrobial agents, mortality of ICU patients with septic shock remains steadily high. Especially in those requiring high dosage of vasopressors, whose 28-day mortality rate could reach 60%. The pathophysiology of septic shock emphasizes on the role of dysregulated host immune response towards inciting microbes, producing excessive inflammatory cytokines which lead to tissue damage and subsequent organ failures. Multiple therapies targeting the overwhelming inflammatory response in patients with septic shock have been studied (ref). While some showed promising results in modulating inflammation in observational studies (ref), none other than systemic corticosteroids lead to better clinical outcomes in the randomized controlled studies. The reasons for their failures are the complexity of the inflammation cascades, where treatments specifically targeting parts of the process may not be able to achieve meaningful effects. Extracorporeal blood purification therapy is an adjunctive treatment option more extensively studied over the last decade. By passing patients' blood or plasma through specifically developed absorber, various inflammatory cytokines are absorbed to resins inside the devices and removed from the circulation. Decreasing levels of inflammatory cytokines may subsequently attenuate systemic inflammation leading to shock reversal and better survival. HA-330 disposable hemoperfusion cartridge (Jafron®, China) is an absorber targeting hyper-inflammatory states including septic shock. It is designed to nonspecifically absorb molecules with molecular weight 10-60 kilo-Dalton, making it effective for removing various pro-inflammatory cytokines and potentially modulating the inflammatory cascade. Previous randomized study in patients with sepsis compared between the add-on 3 daily session of hemoperfusion with HA-330 adsorber and the standard therapy . .Circulating interleukin-6 and interleukin-8 levels of patients underwent hemoperfusion significantly reduced after two sessions when compared to baseline. Their values on day 3 were also significantly lower than those of the control group. Adjunctive hemoperfusion were associated with lower ICU mortality, butno significant difference in hospital and 28-day mortality between the two groups(ref). However, approximately 50% of enrolled patients had sepsis without shock. Generalization of the findings to more severe cohorts of septic shock patients are therefore limited. Patients with septic shock have higher cytokines level than septic patients without shock. Hence, they are theoretically more likely to benefit from therapies aiming to reduce cytokine levels. We hypothesize that adjunctive hemoperfusion with HA-330 adsorber would be associated with better outcomes in a more severe group of patients with septic shock.
BACKGROUND: Anaphylaxis is the most severe form of allergy that rapidly affects multiple body systems and can be deadly. The highest incidence of anaphylaxis is in children and adolescents. In Canada, approximately every 10 minutes there is an Emergency Department (ED) visit for food allergy, and up to 80% of anaphylactic reactions in children are triggered by food. The ambiguity in how physicians manage anaphylaxis adds a huge burden to health care and further contributes to ED crowding. Current Canadian and international treatment guidelines universally recommend that all patients present to the ED for a prolonged period (6-24 hours) of in-hospital monitoring after initial reactions have been treated, to increase detection of biphasic anaphylaxis (BA). BA is a second wave of symptoms after initial resolution. These guidelines are based on poor or little evidence and have unintended negative impacts on patient safety and quality of life. Furthermore, this 'one-size fits all' approach to care leads to wasteful resource utilization that provides low value care. OBJECTIVE: The main objective of the study is to derive a clinical prediction rule that identifies children with anaphylaxis who are at risk of BA. METHODS: This prospective multicenter cohort study will enroll 1682 patients from 7 pediatric EDs that are members of the Pediatric Emergency Research Canada (PERC) network. We will enroll patients < 18 years of age presenting to the ED with an allergic reaction that matches the diagnostic criteria of anaphylaxis. Research assistants (RA) present in the ED will screen, obtain consent, and prospectively collect all study data. The Research Assistant or Research Nurse will follow patients during their ED visit and ascertain, in conjunction with the medical team, if the patient developed biphasic anaphylaxis in the ED. A standardized follow-up survey conducted within 2-5 days of ED or hospital discharge will determine if a biphasic reaction occurred following ED disposition. We established an advisory council comprised of end-users and community partners external to the project team to monitor project milestones. STUDY TEAM: We have established an international multidisciplinary team of experts in pediatrics, emergency medicine, allergy/immunology, research methodology and statistics, and knowledge translation. Our team is supported by the PERC network. EXPECTED OUTCOME: Providing the best evidence-based, value care at the lowest cost is a moral and ethical imperative. Therefore, in alignment with national and international research priorities, we propose to develop a robust prediction model for BA. This model will address a significant gap in current knowledge and practice, with anticipated benefit for patient care and health system efficiency worldwide. This trial will generate novel, clinically relevant data on optimal ED management of children with anaphylaxis that integrates best value care with patient safety.
