Filter by:To determine the efficacy and Security of Thymoglobuline in cadaveric donor Efficacy: To demonstrate that in cadaveric donor, Thymoglobuline diminished graft alloreactivity by decreasing expression of inflammatory markers in graft biopsies Security:To demonstrate that the administration of Thymoglobulin does not have side effects in renal recipients.
The objective of this study is to quantify the association between tissue oxygen saturation (StO2) during the donor management phase of the Death by Neurological Criteria (DNC) organ donor and the number of organs transplanted per donor.
This study's objective is to obtain preliminary data to test the hypotheses that percutaneous liver biopsy in brain death donors is safe and provides reliable histological information. Furthermore, that information when disseminated fully and widely many hours before organ recovery would not only decrease economic costs of wasteful recovery of livers that are not ultimately transplanted but also increase transplantation and decrease cold ischemia times of recovered livers.
The purpose of this study is to assess the feasibility and safety of mild-to-moderate hypothermia as an in-vivo organ preservation strategy compared to normothermia in 60 brain-dead organ donors.
This study concerns the nearest relatives of patients who have passed away within 3 days of admission to an ICU due to: (1) brain death with multiple organ donation +/- tissues or (2) death via limitation and / or cessation of active treatment (LATA) without brain death or (3) sudden death of a previously healthy patient (no physical or mental limitations; MacCabe score = 0) within 3 days of admission to ICU without LATA nor brain death. Our primary objective is to determine the proportion of nearest relatives at risk for post traumatic stress disorder as defined by an Impact of Event Scale score greater than 37, and to compare this factor between the three above-mentioned groups.
The goal is to compare post tramautic stress between the nearest relatives of brain-dead patients who are organ donor to those of brain-dead patients who are not organ donors for medical, legal or opposition reasons.
In France the diagnosis of brain death relies on electroencephalography (EEG) or cerebral angiography. Concerning the latter a time of 6 hours is mandatory between the clinical diagnosis and the realization of the cerebral computed tomography (CT) angiography. Transcranial doppler (TCD) is not recommended in the french guidelines for the diagnosis of brain death. In other countries, some flow patterns allow to confirm the diagnosis of brain death. The hypothesis of our study is that TCD could shorten the time between the clinical diagnosis of brain death and the realization of the CT angiography.
The goal of this study is to evaluate the effect of N-acetyl-cysteine (NAC) administration in organ donors on the kidney graft function of recipients.
Context: A major lack of organ donors is a serious public health problem. It determines a prolonged delay before a transplant can be performed and thus a significant number of deaths of patients waiting for transplantation. The aim of this project is to reduce the delay of the diagnosis of brain death, and also to improve its diagnosis in the Intensive Care Unit. The diagnosis of brain death is strictly defined by the law and relies either on two consecutive flat electroencephalograms recorded at an interval of four hours, or on the lack of cerebral circulation during a brain angiography performed after suspecting brain death on the clinical exam. However, in usual practice, it is difficult to have all the needed clinical arguments, and their interpretation can be difficult in the pathological context. This may participate in the delay and the lack of patients potentially donors. Pre-study: In a pilot study, fifty subjects with severe cerebral lesions, had a continuous ECG recording. The investigators could find that a decrease in autonomic nervous system activity, as measured through the ECG, was correlated to the transition to brain death assessed by cerebral angiography. The loss of cardiac variability was always observed between two cerebral angiographies, one before and the second after brain death. This study allowed the investigators to calculate the threshold values of sympathetic and parasympathetic activities to confirm brain death.
The investigators propose to assess 36 donors' nutritional status using accepted parameters (prealbumin, resting energy expenditure); to assess nutrient intestinal absorption through 13Curacil breath tests; and to evaluate serum concentrations of IL-6 and TNFalpha to determine if continuing or initiating enteral feeding and nutritional supplementation is effective in restoring or maintaining nutritional parameters.
