BACKGROUND AND OBJECTIVES: Organ transplantation has long been considered the treatment of choice for many end-stage organ diseases. As soon as transplantation turned to be a viable therapy, organ shortage became the major limitation for the procedures. Nowadays, there is an increasing imbalance between organ supply and demand. Apparently, the most promising way to increase organ supply is optimizing the care for the brain death organ donor. The objective of this manuscript was to review the pathophysiological aspects and therapeutic strategies for the optimized care of the potential organ donor. CONTENTS: Brain death causes a massive catecholamine release, inducing a variety of deleterious effects that can threat organ perfusion. Studies have documented a sudden decrease in cortisol, insulin, thyroid and pituitary hormones. In this scenario of hemodynamic and metabolic instability, a special attention to the multiple organ donor support is required. CONCLUSIONS: An extensive knowledge of the complex brain death pathophysiology is extremely important for the implementation of rational aggressive management protocols of the potential organ donor, aiming to increase the number of harvested organs and the number of organs harvested per donor.

BACKGROUND AND OBJECTIVES: Cardiac arrest is a state of severe cerebral perfusion deficit. Patients recovering from a cardiopulmonary resuscitation are at great risk of subsequent death or incapacitating neurologic injury, including persistent vegetative state. The early definition of prognosis for these patients has ethical and economic implications. The main purpose of this manuscript was to review the prognostic value of serum Neuron-Specific Enolase (NSE) in predicting outcomes in patients early after a cardiac arrest. CONTENTS: Severe neurologic disability is the most feared complication after a cardiac arrest. Many studies are trying to find prognostic markers that can be associated with outcomes in patients surviving a cardiac arrest. Biochemical markers of neuronal injury seem to be promising in this scenario. Therefore, NSE levels have been studied in patients after a cardiac arrest and high enzyme levels suggest more extensive brain damage and are associated with unfavorable clinical outcomes. CONCLUSIONS: Outcome after a cardiac arrest is mostly determined by the degree of hypoxic brain damage and early determinations of serum NSE level can be a valuable ancillary method for assessing outcome in these patients.

BACKGROUND AND OBJECTIVES: Since organ transplantation has become the treatment of choice for several end-stage diseases, organ shortage is the most important barrier for the procedures and waiting lists are increasing out of proportion. The objective of this study was to review the best practices concerning family referral and how these issues and others aspects of the donation process can influence consent rates. CONTENTS: Despite the growing number of live donors, the brain death donor continuous to be the major source of organs for transplantation and the only source of extra-renal organs. Many problems have been identified in the donation process, including non-identification of the brain death donor, inadequate care of the donors and family refusal to donation. Increasing the consent rate for donation seems to be a good alternative to reduce organ shortage. CONCLUSIONS: Family decision to donate organs is influenced by several aspects. Highly trained professionals in family referral can affect consent rates.
