Active clinical trials for "Shock"

The sepsis and septic shock remain major causes of child morbidity and mortality, despite the use of modern antibiotics and resuscitation therapies. Recent interest has focused on biomarkers for early diagnosis, and evaluation the outcomes of sepsis; but there is a still lack of early diagnosis and timely intervention for sepsis in the emergency department (ED). The primary aim was to investigate the role of C-Reactive Protein(CRP), Procalcitonin(PCT), soluble-urokinase plasminogen activator receptor(suPAR) and Presepsin in the early stratification of patients with sepsis. The usefulness of pediatric Sequential Organ Failure Assessment (pSOFA) for predicting of the mortality and the rate of PICU admission in children with septik shock were also investigated. This prospective pilot study was conducted at academic pediatric ED between September 2017-June 2018. All children who met sepsis criteria admitted to ED were involved to study. They kept following up after ED management and their blood samples were taken upon admission on day 0, 1, 2, 4 and 7. The definition made as sepsis, severe sepsis and septic shock. At the same period, 100 healthy children chosen as the control group. The patient characteristics, clinical features, diagnosis, co-morbidities, source of infection, laboratory results (CRP, PCT, lactate, suPAR and Presepsin) and treatments were recorded. The pSOFA score was calculated during first hour of admission. Length of stay in ED and hospital was noted. The main outcome measure was in 7 and 30-day mortality.

Septic shock is a common syndrome caused by the body's response to an infection. Septic shock is responsible for 10% of all ICU admissions and 30% of ICU deaths. Use of "beta blocker" medications may improve outcomes after septic shock. This pilot study evaluates protocols to infuse the beta blocker esmolol in patients with septic shock.

The objective of this study is to assess the feasibility of estimating the clearance of iohexol as an indirect measure of glomerular filtration rate in patients with unstable renal function in the intensive care unit through analysis of rich iohexol plasma kinetics.

The purpose of this study is to determine if an implant material can be injected to repair nasal valve collapse.

HYPOTHESIS: During anesthetic pre-oxygenation with high FiO2, pulmonary atelectasis occur, especially in patients < 6 years old, where FRC and pulmonary closing volume may overlap. New borns and children <1 year old are especially vulnerable. OBJECTIVES: Validate "air test" as a individualized and non-invasive diagnostic method of clinically significant atelectasis in pediatrics. Determine what other factors contribute to atelectasis development in pediatrics METHODS: 30 pediatric patients will be studied with ages ranged between 45 postconceptional weeks and16 years old. Baseline SpO2 and lung ultrasound will be performed for each patient upon arrival at the operating theatre before preoxygenation with FiO2 of 1.0 SpO2 will be measured 15 min after intubation during a 5 min long "air test" trial (FiO2 0.25). lung collapse will be verified by lung ultrasound at the end of the 15 min trial. Lung collapse will be eventually granted upon lung US verification by a blind researcher.

Sepsis is defined by the occurrence of a systemic inflammatory response syndrome (SIRS) in the context of infection. Unfortunately, its incidence appears to be rising, and the mortality of septic shock remains extraordinary high (> 60%). Death in sepsis arises from shock and multi organ dysfunction that are - at least in part - triggered by an inadequate response of the host's immune system to the infection. Given the injurious role of 1) this overwhelming immune response and 2) the consumption of protective plasmatic factors (e.g. vWF cleaving proteases, hemostatic factors etc.) while the disease is progressing the investigators hypothesize that early therapeutic plasma exchange (TPE) in the most severely ill individuals might improve hemodynamics, oxygenation and ultimately survival. This therapeutic strategy combines 2 major aspects in 1 procedure: 1. removal of harmful circulating molecules and 2. replacement of protective plasma proteins. The investigators designed the EXCHANGE trial to analyze in a randomized fashion the benefit of TPE as an add-on treatment to state of the art standard sepsis care. Only patients with early septic shock (< 12 hrs) and high catecholamine doses (noradrenaline > 0.4 ug/kg bodyweight/min) will be included. Those in the treatment group will receive 3 TPEs within three consecutive days. The primary outcome is 28-day all cause mortality. To show an assumed reduction from 60% to 45% in the experimental group, a sample size of 173 patients per group has been calculated. The overall sample size is therefore n=346. The recruitment period is 3 years (+3 months observation) and will be performed in 11 national centers in Germany. Secondary endpoints (including hemodynamics, oxygenation, coagulation, and microcirculation) will be assessed on day 1, 2, 3 before and after TPE and on day 4, 5, 7 and 14. Project management and data monitoring will be organized by the Hanover Clinical Trial Center and biostatistics including a web-based randomization will be performed by the Institute of biometrics (Prof. Koch) at Hannover Medical School. The investigators hope to demonstrate a potential benefit of an additive treatment approach to improve the outcome of patients suffering from an under-recognized but deadly disease.

Hypovolemia and acute circulatory failure affects more than 60% of patients hospitalized in intensive care or resuscitation. The volume expansion (VE) by fluid replacement therapy is the first treatment improve circulatory function. However, too much VE can be harmful. So, the use of dynamic predictive indicators of fluid responsiveness is recommended in patients with sepsis.In patients with spontaneous ventilation, few studies have evaluated these parameters. In mechanical ventilation, indices based on the respiratory variation of the diameters of vena cava have been studied and validated to predict the response to VE. However there is no similar study in spontaneously breathing patients without ventilatory support. The investigators hypothesize that the respiratory variations in the IVC diameters and femoral artery flow during standardized respiratory cycles are predictive factors of fluid responsiveness in spontaneously breathing patients with sepsis, acute circulatory failure, and regular cardiac rhythm.

Fluid therapy is often used as first line treatment of acute circulatory failure, aiming an increase in cardiac output (by improving preload) and in tissue perfusion. Depending on left ventricular systolic function, fluid challenge could lead to an increase in cardiac ouput and tissue perfusion, or only detrimental consequences (by fluid overload and aggravation of lung and tissues oedema, increase of morbi-mortality). Patients are defined as responders to fluid therapy if one can observe an increase of cardiac output up to 15% after fluid therapy (500ml of crystalloids): gold standard test used in most of the studies on the subject. Literature reports on heterogenous populations a reproductible and constant response rate to this fluid challenge of 50%. It seems reasonable to dispose of indices allowing to predict fluid responsiveness without resulting in fluid intake. Statics markers have been abandonned for several years and dynamics methods have been developped. In front of arrythmia, validated methods are scarce. Passive leg rising method appears to be the only one and it's validity seems to be less well documented than in sinusal patients. The purpose of this study is to determine a new method to assess fluid responsiveness in arrythmic patients. In atrial fibrillation, RR interval varies widely between cardiac cylces. Systolic interval remain constant. Variations will occure at expense of diastolic interval, or ventricular filling interval. One can reliably assume that when RR is longer, preload is rising. If the patient is on the ascendant part of the Franck-Starling curve, a longer RR should cause au greater VTI (Vitess Time Integral, surrogate of cardiac output). The evaluation by transthoracic echocardiography of the indice delta ITV / delta RR should determine the degree of fluid responsiveness in arrhythmic patients. After decision of fluid expansion, patients will have haemodynamic and echocardiographic data measured, delta ITV / delta RR indice assessed, then passive leg rising and fluid expansion with 500 ml of cristalloids administered, with evaluation of VTI (as surrogate of cardiac output) at each time. Fluid responders will be compared to non-responders to evaluate the diagnostic performances of the indice delta ITV / delta RR.

The purpose of this study, in mechanically ventilated septic shock patients, is to determine whether a fluid loading strategy based on parameters derived from the transpulmonary thermodilution technique may lead to more ventilator free days compared to a fluid loading strategy based on the surviving sepsis guidelines.

We conducted this study to assess the value of early change in central venous pressure (CVP) in predicting fluid responsiveness in mechanically ventilated patients.
