Critically IllAcute Kidney Injury1 more

Record the renal resistive index and hemodynamic parameters ( record the cardiac output and stroke volume if the patient's next to kin agree to undertake a PiCCO monitoring ) before and after resuscitation for severe sepsis or septic shock patients, to determine whether the changes of resistive index or hemodynamic parameters, especially the cardiac output can be a better parameter to predict AKI

NIRS Directed Optimal Cerebral Perfusion Pressure in Septic Shock Patients: A Feasibility Study...

The Time Used for Determining Optimal CPP

After the initial injury, secondary insults including poor cerebral perfusion are main contributors to poor outcome and their early detection and amelioration are keystone to neurocritical care. Nonetheless, the guidelines for blood pressure management still recommend a single target blood pressure for critically ill patients: the international Guidelines for management of sepsis recommend a MAP of at least 65 mmHg; Some guidelines recognize that patients with a history of hypertension may require a higher MAP. However, these guidelines do not currently recommend cerebral autoregulation-guided therapy and leave many unanswered questions. Cerebral autoregulation is the mechanism that maintains cerebral blood supply, hence CBF approximately constant despite changes in MAP or, more precisely, despite changes in CPP. Maintaining blood pressure within the cerebral blood flow (CBF) autoregulation range (termed "optimal MAP") is associated with improved outcomes for patients. The observational data suggests that management of patients above or below CPPopt 5mmHg is associated with better outcomes and mortality than the other greater variation range.The most commonly used method for monitoring dynamic cerebrovascular reactivity is the pressure reactivity index (PRx) that uses ICP as a surrogate for CBV. However, assessing the PRx requires invasive ICP monitoring which limits its application in many clinical areas. Alternatively, in the absence of invasive intracranial pressure monitoring to determine CPP, a continuous autoregulation monitoring can be accomplished by the continuous correlation between transcranial Doppler (TCD)-measured CBF velocity of the middle cerebral artery and the mean arterial blood pressure (termed mean velocity index or Mx) . Mx is a validated index of cerebral autoregulation based on measures of cerebral perfusion pressure and mean flow velocity on transcranial doppler but is impractical for longer-term monitoring and requires system training, the results are operator-dependent. Near-infrared spectroscopy (NIRS) measurements is another alternative for real-time autoregulation monitoring in the form of a Tissue Oxygenation Index. In contrast to TCD, the NIRS sensors are very easy to apply (the probes attach to the forehead with self-adhesive pads) and do not require frequent calibration making them more suitable for long-term monitoring. Therefore, in this study, Patients in the intervention group will be monitored by continuous NIRS and invasive blood pressure monitoring. The correlation curve between ORI/THx and blood pressure will be obtained through continuous monitoring. According to the correlation curve, the optimal blood pressure which provides the optimal CPP will be determined.

Does Urinary TIMP2 and IGFBP7 Can Identify High Risk Patients of Progression From Mild and Moderate...

Acute Kidney InjurySeptic Shock

Septic shock is one of the leading causes of death in patients admitted to the intensive care unit (ICU). Acute kidney injury (AKI) occurs in almost 50% of septic patients and is associated with significant mortality. Progression to the last stage (KDIGO stage 3) of AKI is an important step in the disease, as it usually requires initiation of RRT. Renal biomarkers are unable to accurately identify those patients who will progress to severe AKI (KDIGO 3). However, identification of patients at risk of progression to severe AKI could help the clinician to initiate optimal therapy including RRT. A new urine test, the Nephrocheck™ corresponding to the product of the urinary concentrations of 2 markers of renal tubule injury (TIMP2 and IGFBP7) has been validated. The Investigator have already performed two previous studies including septic shock patients (AKICHECK and BIOOCHECK). those previous datas will be reanalysed to examine whether the new urinary biomarkers TIMP2 and IGFBP7 can predict progression within 24 hours and 72 hours from mild and moderate (KDIGO 1 or 2) to severe AKI (KDIGO 3) in patients with septic shock. -All the datas required will be collected from two previous studies (AKICHECK and BIOCHECK) performed in 3 centers: Amiens medical ICU, Melun medico surgical ICU and Montpellier Medical ICU.

Bloodstream Infection Due to Multidrug-Resistant Organisms - Multicenter Study on Determinants of...

Bloodstream InfectionSeptic Shock

Continual surveillance of both community-acquired and nosocomial bloodstream infections for specific target organisms. Analysis of comorbidities, complications, bacterial resistance patterns, bacterial genomics (e. g. via WGS and MLST typing) for the determinants of clinical outcomes. The clinical outcomes are investigated both in the short-term (up until discharge) and the long-term (six months after index blood culture by standardized questionnaire). A predictive point-of-care score is to be developed based on these data to define high-risk patient populations requiring more intensive diagnostic and/or treatment regimens.

Prospective observational, open-label mono-center study to compare a completely bedside blood culture diagnostics system (BACTEC blood culture system in combination with the Accelerate ID/AST System and Curetis Univero System) with standard blood culture diagnostics in patients with sepsis or septic shock.

Fluid REsponsiveness and Arterial ELASTANCE in Patients With Septic Shock or After Aortic Surgery...

ShockSeptic7 more

The MostCare system, thanks to the Pressure Recording Analytical Method (PRAM; Vygon, Padua, Italy), provides new hemodynamic parameters of the cardiovascular system. The PRAM method is a noncalibrated pulse contour method which requires only an arterial line (radial or femoral). This method has been validated in various clinical conditions. Among the collected parameters, some are well known and used daily care in Intensive Care Unit (ICU), i.e. cardiac output (CO), arterial pressure, heart rate, stroke volume (SV). Others such as arterial elastance (Ea) or dicrotic pressure are more recent and merit further investigation to determine their interest in clinical practice. To date, it is rarely used to adapt therapies, mostly because of a lack of knowledge regarding the evolution of these parameters. The aim of this study is to analyze the relationship between the evolution of Arterial Elastance and fluid responsiveness after a 250 mL fluid challenge of crystalloids in 5 minutes in patients with either septic shock or in the postoperative course of a major vascular surgery. Patients will be considered fluid responders if an increase >10% of the stroke volume is observed .

Barrier Function and Production of Inflammatory Cytokines in the Rectal Mucosa in Patients With...

Septic Shock

Life-threatening infection impairs bloodflow to the gut, thereby causing less delivery of oxygen. This leads to increased formation of different inflammatory and infectious markers. The investigators hypothesize, therefore, that there is a significant difference in the concentrations of inflammatory and infectious markers in the rectal mucosa between patients with septic shock and healthy controls.
