Delayed xenon treatment following trauma improves neurological outcome 24 hours after trauma. Xenon-treated animals (grey bars) received 75% xenon : 25% oxygen for 3 hours duration, starting at 15 minutes, 1 hour, 3 hours or 6 hours after trauma. Control animals (white bar) received 75% nitrogen : 25% oxygen. Neurological outcome was measured 24 hours after trauma. Bars represent mean values and error bars are standard errors (n=34, control; n=21, xenon 15 min; n=8, xenon 1 hr; n=9, xenon 3 hr; n=9, xenon 6 hr) * = p<0.05 compared to control.
