Figure 2. Urinary glucose concentrations in 13 volunteers measured before anesthesia and on the 4 days after anesthesia. There were no significant changes in average urinary glucose concentrations on any day after 8 h of 1.25 minimum alveolar concentration of sevoflurane. Two men had urinary glucose concentrations that exceeded the upper limit of normal on the first day after sevoflurane. The scale on the y axis was chosen to be identical to that of a previous publication. [5]
