Combined epidural and general anesthesia versus general anesthesia for abdominal aortic surgery.

abstract：BACKGROUND:The current study was designed to investigate the influence of pretreatment with the oxygen radical scavengers polyethylene glycol superoxide dismutase and catalase (SODCAT) on altered opioid-induced pial artery dilation after fluid percussion brain injury (FPI) in the newborn pig.
