Filter by:The BRACKETS pilot study is a multicentre, prospective, randomized controlled trial of prophylactic preoperative tranexamic acid (TXA) versus placebo and, using a partial factorial design, of prophylactic preoperative desmopressin versus placebo.
Fluid overload is harmful in critically ill patients; In addition to increasing mortality, it may increase the incidence of acute kidney injury (AKI), length of ICU stay, and duration of mechanical ventilation by causing end-organ damage. (1-3) Mortality attributable to AKI is 20% and is an independent determinant of mortality. (4) Venous load ultrasonography score (VExUS) is a new systemic congestion scoring method based on inferior vena cava dilation and pulsed wave Doppler (PW-Doppler) morphology of the hepatic, portal and renal veins. It has been proposed as a score to assess systemic congestion. When the IVC diameter is < 2 cm, it means there is no congestion and VEXUS is 0. Mild congestion: In addition to the IVC measuring approximately 2 cm, normal patterns such as the systolic wave being greater than the diastolic wave in the hepatic vein PW-doppler, pulsatility below 30% in the portal vein Doppler, continuous flow in the renal vein PW-doppler, or slightly abnormal patterns, i.e. hepatic The systolic wave in vein PW-doppler is smaller than the diastolic wave, the pulsatility in portal PW-doppler is between 30-50%, and the renal vein PW-doppler is accompanied by biphasic flow, and VEXUS is scored as 1. Moderate congestion is scored as VEXUS 2, which is measured as IVC 2 cm or more, plus inversion of the systolic wave on hepatic vein PW-doppler, pulsatility greater than 50% on portal PW-doppler, and discontinuous monophasic flow with only the diastolic phase on renal vein PW-doppler. It is accompanied by one of the serious abnormal patterns such as There is severe congestion, that is, VEXUS 3: IVC diameter of 2 cm or more and the presence of at least two seriously abnormal PW-Doppler morphologies. (5) The primary aim of this study is to describe the prevalence of venous congestion based on VExUS in general ICU patients. Secondary outcomes were to evaluate the association between VExUS, AKI, and 28-day mortality.
Predictors of Acute Kidney Injury in critically ill children admitted to PICU during one year.
This retrospective cohort study of patients classified by the blood glucose level after reperfusion in liver transplantation repicient. Our object is to investigate whether controlling BG levels within the optimal range during neohepatic phase is associated with a reduction of AKI incidence. Furthermore, severe AKI, chronic kidney disease (CKD), major adverse cardiac event (MACE) and mortality were also investigated.
Shock state is defined as an acute, life-threatening, circulatory failure with impaired tissue oxygenation (or tissue hypoxia). The cause of the shock state can be septic, anaphylactic, hypovolemic or cardiogenic. Its management is based on etiological treatment and replacement of organ failures. Acute kidney injury (AKI) may be lead by renal hypoxia. Acute kidney injury is frequent in patients admitted to intensive care unit (ICU) and associated with an increased mortality. Serum creatinine is the reference biological marker in the diagnosis of Acute kidney injury. However, its use is limited by a delayed increase in plasma creatinine level in relation to the causal renal agression, at a time when renal tissue damage may already be established. Thus, the identification of a biological marker making it possible to estimate renal hypoxia continuously during a shock could allow us to identify early a situation at risk of evolving into Acute kidney injury. The renal medulla is vulnerable to tissue hypoxia with a risk of acute tubular necrosis. As in situ measurement of mPO2 is not possible in current practice in humans, several studies have shown a positive correlation between variations in mPO2/uPO2 and occurence of Acute kidney injury. In humans, studies have shown a significant association between the reduction in uPO2 in cardiac surgeries and the occurrence of postoperative Acute kidney injury. The aim of the study is to describe the association between uPO2 values and the onset of Acute kidney injury and/or the ocurrence of early recovery of renal function after Acute kidney injury. Any patient in shock (group A) or without shock and requiring urinary catheterization as part of treatment (group B) admitted to the Medical-Intensive Care Unit of Angers University Hospital is eligible for inclusion. After inclusion, a continuous uPO2 measuring probe is introduced with the placement of the urinary probe. uPO2 is collected continuously for the first 5 days of admission or until discharge from intensive care or removal of the urinary catheter. uPO2 is also measured by a gasometry on a urine sample on a multi-daily basis. Serum creatinine is collected every 12 hours (twice a day) and diuresis every two hours for 5 days.
Tacrolimus is the most commonly used immunosuppressant for preventing and treating rejection after liver transplantation. However, its treatment window is narrow, the pharmacokinetic individual differences are large, routine dose according to body weight, sometimes low dose will cause graft rejection of patients, or high dose will lead to infection and liver and kidney toxicity and other adverse reactions. Moreover, the conventional drug testing can not fully reflect the efficacy of tacrolimus, and there are shortcomings of lag, experience and passivity. FK506 is metabolized primarily by cytochrome P450 member 3A5 in the liver and intestines. CYP3A5*3 is the most important factor determining the expression level of CYP3A5. This mutation can cause variable shear and produce unstable protein, so that patients carrying CYP3A5*3/*3 gene do not express CYP3A5. Acute kidney injury is a common and important complication after liver transplantation. Despite recent advances in organ preservation, surgical techniques, and immunosuppressive protocols, the incidence of AKI after orthotopic liver transplantation remains high. AKI has a significant impact on both short - and long-term prognosis of orthotopic liver transplantation recipients. Studies have shown that orthotopic liver transplantation recipients with AKI have significantly higher mortality rates in hospital, at 28 days and at 1 year after surgery than those without AKI. In this study, the relationship between donor and recipient CYP3A5 gene polymorphism and tacrolimus concentration was investigated, and the effect of donor and recipient CYP3A5 gene polymorphism and tacrolimus concentration on acute kidney injury after liver transplantation was investigated. To provide guidance for individual administration of gene-directed tacrolimus in patients, and provide basis for prevention and reduction of postoperative acute kidney injury in liver transplantation patients.
In this prospective observational study, patients hospitalized in mixed intensive care unit, aged between 18 and 80, and diagnosed with sepsis and septic shock according to sepsis-3 criteria will be included. To determine whether patients develop AKI during the first five days of ICU admission, creatinine and urine output will be monitored daily for the first five days of ICU admission according to KDIGO criteria. Clinical diagnosis and treatment of AKI will be made according to KDIGO. According to KDIGO, patients will be divided into two groups: those who develop AKI and those who do not. By comparing plasma NGAL and VEXUS scores between groups, the sensitivity and specificity of the VEXUS score in determining AKI will be determined.
This is a multicenter international observational prospective cohort study.
