Comparative StudyAntegrade versus retrograde cerebral protection in repair of acute ascending aortic dissection.
The objective of this study was to compare retrograde with antegrade cerebral protection during acute aortic dissection repair using cerebral oximetry measurements. Fifty consecutive acute ascending aortic dissection repairs were analyzed. Cerebral oximetry data were collected for 41 of 50. ⋯ The per cent change from the prearrest value for the antegrade patients was: right -12 per cent and left -15 per cent; the per cent change from prearrest for retrograde patients was: right -15 per cent and left -16 per cent (P values 0.514 and 0.956, respectively). No compelling evidence for an advantage to either antegrade or retrograde cerebral perfusion was detected. Further study with a focus on neurologic outcomes is warranted.

The impact of early hormonal therapy in catastrophic brain-injured patients and its effect on organ procurement.
The purpose of this study was to evaluate the impact of early hormonal therapy on organ procurement from catastrophic brain-injured patients. All catastrophic brain-injured patients admitted to a high-volume academic Level I trauma center who underwent successful organ procurement over a 3-year period (2006 to 2008) were reviewed. Patients were divided into two groups, those who received hormone therapy (HT) before brain death (BD) declaration and those who received HT after BD declaration. ⋯ Patients receiving HT before BD had significantly more organs procured (4.5 ± 1.5 vs 3.5 ± 1.3, P = 0.023). Although catastrophic brain-injured patients receiving early hormonal therapy were more hypotensive, they required less vasopressors and had higher procurement rates. The early use of hormonal therapy may decrease the need for vasopressors and increase the salvage of potentially transplantable organs.
