Active clinical trials for "Shock"

Patient tolerance of pain from discharges of implantable cardioverter defibrillators (ICD's) is highly variable. It can be influenced by psychological factors, physical condition and the number of shocks delivered. It has been shown that cutaneous pain perception can be reduced by delivery of a weak , low voltage pulse (prepulse)prior to the delivery of a stronger shock. A prepulse delivered before a high voltage ICD shock will decrease discomfort compared to a shock of equal energy without a prepulse.

QuantiFERON Monitor® is an immunological test evaluating the nonspecific cellular response by measuring interferon gamma (IFNγ) secretions after T-cell and natural killer lymphocyte stimulation. This study aims at evaluating sepsis-induced immunosuppression base on QuantiFERON Monitor® in patients presenting to the intensive care unit for septic shock. The sponsor expects to identify sepsis-induced immunodeficiency in patients through a better understanding of cellular and adaptive immune responses.

The purpose of this study is to determine whether midodrine administration decreases duration of intravenous vasopressors and intensive care unit length of stay for patients in septic shock.

Suspension syndrome refers to a potentially life-threatening condition that can occur in unconscious persons after prolonged suspension in a harness. To date, our understanding of the pathophysiology and appropriate treatment is based primarily on case reports and expert opinion. The main pathophysiological hypothesis implicates blood pooling in the lower extremity and lack of return via muscle pumping. However, a recent French study could not support this hypothesis. Other mechanisms, such as a central vagal reflex may play a role in the pathophysiology of suspension syndrome. The aim of this study is to better understand the pathophysiological basis of suspension syndrome and to develop practical recommendations for prevention and treatment.

A retrospective, observational study was performed about the patients with septic shock who admitted into intensive care unit (ICU) from January 1, 2015 to February 29, 2016. The number of patients who received empiric antibiotic treatment within first hour after septic shock diagnosis were collected. Detailed information about clinical ladder for nursing stuff and nursing shift were collected . Clinical ladder for nursing stuff is a new definition based on education background and work experience and nurses stuff are classified into four levels. N0 was defined who got college degree or above, nurse qualification certificate and working time less than one year. N1 an N2 were defined as who got nurse qualification certificate and working time between 1~3 years and more than three years, respectively. N3 was defined who was nurse-in-charge qualification or got nurse practitioner qualification for more than five years. Compliance of empiric antibiotic treatment within first hour and evaluate the effect of nursing stuff on the compliance were calculated.

This study evaluates the usefulness of pro-adrenomedullin (precursor of a vasodilatory peptide involved in septic shock pathogenesis) and copeptin (a stable peptide of the arginine vasopressin precursor) to predict, at the moment of septic shock diagnosis or their changes at 6 hours, the vasopressor requirements (measured by inotropic index and vasopressor dependency ratio) and volume requirement for resuscitation.

The aim of this pilot study is to determine, as exhaustively as possible thanks to the continuous and precise recording of heart rhythm, the frequency of de novo atrial fibrillation in septic shock, which is currently unknown, and to identify specific factors that could be associated with the condition. These will be investigated more precisely in a future study. This constitutes the first step in a reflection on the management of Cardiac Arrhythmia by Atrial fibrillation (ACFA) in septic shock in Medical Intensive Care, known as a major prognostic factor for morbimortality, but for which management is uncertain in the absence of reference data.

Retrospective study to examine the effects of chronic antihypertensive medications on vasopressor dosing in septic shock

This study evaluates the use of early mechanical circulatory support in patients presenting with acute myocardial infarction and cardiogenic shock. Patients are treated according to the National Cardiogenic Shock Initiative protocol, which emphasizes early identification of cardiogenic shock and rapid delivery of mechanical circulatory support based on invasive hemodynamics. All patients treated in this manner are enrolled in the National Cardiogenic Shock registry.

We conducted this study aiming to assess the performance of muscle Lactate and lactate to pyruvate (L/P) ratio clearance in predicting mortality in septic shock patients by using microdialysis.
