Anesthesia as the name suggests is a kind of injection or local medicine that is given to a person to make him unconscious. This geriatric anesthesia is majorly used for the elderly people. It is not used for young persons or adults. Elderly patients sometimes are not capable to bear pain even if it is not that severe. In that case this anesthesia is given to them. High-impact journals are those considered to be highly influential in their respective fields. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
