CS increased MPO activity at 1 hour. NAC did not reduce MPO activity compared with CS initially. NAC reduced MPO activity at 24 hours compared with CS alone, whether given before onset of CS or after CS release. Bar = mean; error bar = SD; control = control group; CS = compartment syndrome group; NAC = group given N-acetylcysteine prior to CS; NACd = group given N-acetylcysteine at CS decompression.
