Abstract

Hemodynamic, neurohumoral, and immunological alterations may combine to deteriorate the intrinsic quality of the organ procurement and/or exacerbate ischemia/reperfusion injury during the ensuing cold preservation and transplantation. This study aims to investigate microcirculatory changes through the in vivo and in situ observation of the mesenteric microcirculation in a rat model of brain death and the effects of continuous thoracic epidural anesthesia (0.5% bupivacaine) on the development of the inflammatory process. The design includes the investigation of: (1) leukocyte-endothelial interactions in the mesenteric microcirculation by intra-vital microscopy; (2) expression of P-selectin and ICAM-1 on mesenteric microvessels by immunohistochemistry; (3) serum cytokines and corticosterone levels by ELISA; (4) hemodynamic parameters, blood gases and electrolytes, and blood leukocyte counts.
