Imminent brain death: point of departure for potential heart-beating organ donor recognition

Contains fulltext : 88186.pdf (publisher's version ) (Closed access)PURPOSE: There is, in European countries that conduct medical chart review of intensive care unit (ICU) deaths, no consensus on uniform criteria for defining a potential organ donor. Although the term is increasingly being used in recent literature, it is seldom defined in detail. We searched for criteria for determination of imminent brain death, which can be seen as a precursor for organ donation. METHODS: We organized meetings with representatives from the field of clinical neurology, neurotraumatology, intensive care medicine, transplantation medicine, clinical intensive care ethics, and organ procurement management. During these meetings, all possible criteria were discussed to identify a patient with a reasonable probability to become brain dead (imminent brain death). We focused on the practical usefulness of two validated coma scales (Glasgow Coma Scale and the FOUR Score), brain stem reflexes and respiration to define imminent brain death. Further we discussed criteria to determine irreversibility and futility in acute neurological conditions. RESULTS: A patient who fulfills the definition of imminent brain death is a mechanically ventilated deeply comatose patient, admitted to an ICU, with irreversible catastrophic brain damage of known origin. A condition of imminent brain death requires either a Glasgow Coma Score of 3 and the progressive absence of at least three out of six brain stem reflexes or a FOUR score of E(0)M(0)B(0)R(0). CONCLUSION: The definition of imminent brain death can be used as a point of departure for potential heart-beating organ donor recognition on the intensive care unit or retrospective medical chart analysis.1 september 201

CP/MAS \u3csup\u3e13\u3c/sup\u3eC n.m.r. study of polyamide-6:spectra and spin-lattice relaxation times

\u3cp\u3eCP/MAS \u3csup\u3e13\u3c/sup\u3eC n.m.r. spectra and \u3csup\u3e13\u3c/sup\u3eC spin-lattice relaxation times (T\u3csub\u3e1\u3c/sub\u3e) of solid polyamide-6 (Ny-6) have been observed. The effect of sorbed water, fast cooling of the Ny-6 melt and addition of ethylene-vinyl alcohol (EVOH) copolymer to Ny-6, respectively, on the spectra and the T\u3csub\u3e1\u3c/sub\u3e values have been investigated. Sorbed water did not affect the spectra and the T\u3csub\u3e1\u3c/sub\u3e values significantly. However, differences could be observed between the spectra and T\u3csub\u3e1\u3c/sub\u3e values of Ny-6 powder, Ny-6 film and Ny-6 in the blends.\u3c/p\u3
