Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
A redistribution of body heat from core to peripheral tissues causes a rapid decrease in core temperature. The present study tested whether a dobutamine infusion would facilitate redistribution and induce a further decrease in core temperature. Volunteers were randomly assigned to the control group (n = 8) and the experimental group (n = 8). They were anesthetized with isoflurane at an end-tidal concentration of near 1.2% for 120 min. In the experimental group, dobutamine was infused at a rate of 4 μg · kg · min. Core temperature, skin temperature, tissue temperature, and laser-Doppler perfusion index were measured. Leg heat content was calculated by morphometric data and observed temperatures. The decrease in leg heat content was larger in the control group than in the experimental group 30 min after anesthetic induction (P < 0.05). In contrast, the core temperature decreased further in the dobutamine group than in the control group 40 min after induction (P < 0.05). Dobutamine induced further hypothermia, presumably by facilitating heat transfer and by increasing cutaneous heat loss. Hypothermia will be increased when using dobutamine for anesthesia.
