Arterial blood pH, PaCO2, PaO2 and glucose levels were not statistically different following sevoflurane exposure as analyzed by t-test, all P>0.05). PaCO2, partial pressure of carbon dioxide; PaO2, partial pressure of oxygen; LS, subanesthetic concentration, 0.1 MAC; MS, subclinical concentration, 0.3 MAC; HS, highest tolerated concentration, 0.7 MAC.
