Filter by:This phase II trial studies how well early metabolic resuscitation therapy works in reducing multi-organ dysfunction in patients with septic shock. Early metabolic resuscitation is made of large doses of glucose, protein, and essential metabolic molecules that may help lower the effects of septic shock on the body. Giving patients early metabolic resuscitation in combination with standard of care may work better in reducing multi-organ dysfunction syndrome in patients with septic shock compared to standard of care alone.
Interventional study comparing effect of two regimes of fluid challenge in patients with sepsis and in patients undergoing elective major surgery on glycocalyx by using perfused Boundary Region in sublingual microcirculation.
This observational nation-wide study is focused on evaluation of the new possible biomarkers for pediatric sepsis and their specificity/sensitivity in combination with usual diagnostic markers for sepsis in the terms of early identification of sepsis, severe sepsis, and septic shock.
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.
The purpose of this study is to determine whether the combination therapy (vitamin C,thiamine and hydrocortisone) is effective in the treatment of septic shock.
Albumin is a key regulator of fluid distribution within the extracellular space and possesses several properties beyond its oncotic activity, including binding and transport of several endogenous molecules, anti-inflammatory and anti-oxidant actions, nitric oxide modulation, and buffer function. The accumulating evidence suggests that supplementation of albumin may provide survival advantages only when the insult is severe as in patients with septic shock. Prospective randomized trials on the possible impact of albumin replacement in these patients with septic shock are lacking. The aim of the study is to investigate whether the replacement with albumin and the maintenance of its serum levels at least at 30 g/l for 28 days improve survival in patients with septic shock compared to resuscitation and volume maintenance without albumin. In this prospective, multicenter, randomised trial, adult patients (≥18 years) with septic shock will be randomly assigned within a maximum of 24 hours after the onset of septic shock after obtaining informed consents to treatment or control groups. Patients assigned to the treatment group will receive a 60 g loading dose of human albumin 20% over 2-3 hours. Serum albumin levels will be maintained at least at 30 g/l in the ICU for a maximum of 28 days following randomization using 40-80 g human albumin 20% infusion. The control group will be treated according to the usual practice with crystalloids as the first choice for the resuscitation and maintenance phase of septic shock. The primary end point is 90 days mortality and secondary end points include 28-day, 60-day, ICU, and in-hospital mortality, organ dysfunction/failure, and length of ICU and hospital stay. In total 1412 patients need to be analyzed, 706 per group. Assuming a dropout rate of 15%, a total of 1662 patients need to be allocated.
Patients with septic shock would be screened. Following this, patients meeting the inclusion and exclusion criteria will be screened and randomized to the two treatment groups. Standard criteria will be considered to define refractoriness to fluids. In all patients, baseline endotoxin activity assay and blood and urine sample will be stored for looking at the effect of therapy on these factors. Septic shock would be defined as clinical construct of sepsis with persisting hypotension requiring vasopressors to maintain MAP>=65 mm of Hg and having a serum lactate >2 mmol/L despite adequate volume resuscitation. Patients assigned to the treatment arm and who do not already have access for dialysis will have a standard hemodialysis catheter inserted in one of the femoral veins by the physician. Hemoperfusion will be carried out for one session within 12 hours for all randomized patient using the adsorption columns for Jianfan Biotechnology Co., Zhuhai, China). The hemoperfusion apparatus will be connected in front of the hemodialyzer in series. The procedure would be done for 2 hours without use of heparin with use of normal saline for pipeline flushing. In patients who also require hemodialysis the dialysis would subsequently be continued. Subsequent sessions of therapy would be done for patients (if required).
The hypothesis of the investigators is that patients with septic shock in ICU have acute intestinal insufficiency favoring subclinical microbial translocation, which is the consequence of alterations of the epithelium, and is accompanied by qualitative and quantitative changes in the gut microbiota. The primary objective is to determine the incidence of microbial translocation by measuring 16S rDNA and 18S rDNA plasma levels in a patient population with septic shock. Secondary objectives are: - Describe the kinetics of markers of intestinal insufficiency (I-FABP / zonulin) over time (at admission, 12 hours after admission, one day, two day, three days and seven day after admission). - Study the correlation between the titer of I-FABP, zonulin, 16srDNA, 18srDNA and the stages of acute gastrointestinal insufficiency (AGF). - Establish correlations between the microorganisms of the intestinal microbiota and the bacteria involved in microbial translocation. - Study the possible correlations between the 16SrDNA levels and the other bacterial markers (sCD14, LBP). - Describe the evolution of the composition and the diversity of the gut microbiota in the first 7 days of septic shock
The aim of this observative, prospective study is to evaluate if and to what extent glycocalyx damage/microcirculation data at admission in the ICU as well as during ICU stay can be predictive of mortality and clinical course in patients presenting with the suspicion of sepsis/septic shock. Therefore, the enrollment of ca 100 ICU patients is planned.
The aim of the work is to investigate the effect of using lidocaine in combination with low dose ketamine in induction of anesthesia for septic shock patients compared to normal dose of ketamine.
