1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

backgroundIn pediatric patients, the use of processed EEG monitoring may reduce the amount of anesthesia administered while maintaining adequate depth of anesthesia.

aimsThe primary aim of this study was to evaluate whether use of a BIS monitor to guide sevoflurane administration might reduce the average end tidal sevoflurane concentration used in children 4-18 years of age.

methodsParticipants in three age groups (4-8, 9-12, and 13-18 years) were randomized to either the BIS guided group or the control group. Use of sevoflurane as the primary maintenance anesthetic was the only requirement in both arms. In the BIS guided group, sevoflurane was titrated to achieve a target BIS value of 45-60 during the maintenance period. In the control arm, clinicians were blinded to the BIS value. Primary outcome was mean end-tidal sevoflurane concentration during maintenance phase of anesthesia. Secondary assessments included time to discharge and the readiness and quality of recovery as assessed by the Pediatric Anesthesia Emergence Delirium scale, the modified Aldrete Score, and the Wong-Baker FACES scale. An intention-to-treat analysis was used to analyze and compare groups.

resultsA total of 180 participants were randomized. Following randomization, 10 participants did not undergo any study procedures, leaving 84 participants in the BIS guided group and 86 participants in the control group. Across all age groups, the average end-tidal sevoflurane concentration was less in the BIS guided group compared to control (4-8 years: 2.2% ± 0.3% vs. 2.4% ± 0.4%, -0.3% [-0.4%, -0.1%]; 9-12 years: 1.7% ± 0.5% vs. 2.1% ± 0.6%, -0.4% [-0.7%, -0.1%]; 13-18 years: 1.6% ± 0.4% vs. 1.9% ± 0.5%, -0.3% [-0.5%, -0.1%]). No differences in recovery outcomes between treatment groups were observed.

conclusionsIn pediatric participants, the BIS guided group reported a lower average end-tidal sevoflurane concentration compared to control, though no significant differences in recovery profile were noted. CLINICAL IMPLICATIONS: The Bispectral Index (BIS) is a processed EEG tool that can be used to titrate general anesthesia to achieve desired anesthetic depth. Brain monitoring with BIS resulted in lower average end-tidal sevoflurane concentrations in children aged 4-18 years undergoing general anesthesia.
