| Abstract |
We examined the hypothesis that 1 minimum alveolar concentration (MAC) of desflurane and sevoflurane provides different depth of anesthesia. One hundred and twenty young (20-30 years), middle-aged (31-65 years), and elderly (66-80 years) patients were randomly allocated to receive either desflurane or sevoflurane (n = 20, each group). General anesthesia was induced with propofol 2 mg/kg bolus and remifentanil 0.25 µg/kg/min, which was stopped after tracheal intubation. Maintenance of anesthesia was started with an end-tidal concentration of desflurane or sevoflurane at age-adjusted 1 MAC and maintained for 10 min, followed by 1-min assessment of bispectral index (BIS), 95% spectral edge frequency (SEF95), and amplitude of the electroencephalogram taken at 10-s intervals. BIS and SEF95 in patients receiving 1 MAC desflurane were significantly lower than those receiving 1 MAC sevoflurane including all age groups [35 (29, 39) vs. 41 (38, 49); 12.53 (10.99, 13.95) Hz vs. 14.42 (12.99, 17.17) Hz median (25, 75 percentile), respectively, P < 0.001 for both]. Both BIS and SEF95 in young patients were lower than in middle-aged and elderly patients receiving either desflurane or sevoflurane (P < 0.001 for both). There were no differences in amplitude between patients receiving desflurane and sevoflurane. BIS as well as SEF95 were lower in patients receiving 1 MAC desflurane than those receiving 1 MAC sevoflurane, suggesting that desflurane provides higher depth of anesthesia than sevoflurane at 1 MAC. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 10 August 2017.
All research outputs
#20,442,790
of 22,997,544 outputs
Outputs from Journal of Anesthesia
#700
of 824 outputs
Outputs of similar age
#277,323
of 317,853 outputs
Outputs of similar age from Journal of Anesthesia
#8
of 9 outputs
Altmetric has tracked 22,997,544 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 824 research outputs from this source. They receive a mean Attention Score of 3.1. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 317,853 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 9 others from the same source and published within six weeks on either side of this one.
