BACKGROUND
Since current general interest in anesthesia is unknown, we analyzed internet keyword searches to gauge general interest in anesthesia in comparison with surgery and pain.
METHODS
The trend of keyword searches from 2004 to 2010 related to anesthesia and anaesthesia was investigated using Google Insights for Search. The trend of number of peer reviewed articles on anesthesia cited on PubMed and Medline from 2004 to 2010 was investigated. The average cost on advertising on anesthesia, surgery and pain was estimated using Google AdWords. Searching results in other common search engines were also analyzed. Correlation between year and relative number of searches was determined with p< 0.05 considered statistically significant.
RESULTS
Searches for the keyword "anesthesia" or "anaesthesia" diminished since 2004 reflected by Google Insights for Search (p< 0.05). The search for "anesthesia side effects" is trending up over the same time period while the search for "anesthesia and safety" is trending down. The search phrase "before anesthesia" is searched more frequently than "preanesthesia" and the search for "before anesthesia" is trending up. Using "pain" as a keyword is steadily increasing over the years indicated. While different search engines may provide different total number of searching results (available posts), the ratios of searching results between some common keywords related to perioperative care are comparable, indicating similar trend. The peer reviewed manuscripts on "anesthesia" and the proportion of papers on "anesthesia and outcome" are trending up. Estimates for spending of advertising dollars are less for anesthesia-related terms when compared to that for pain or surgery due to relative smaller number of searching traffic.
CONCLUSIONS
General interest in anesthesia (anaesthesia) as measured by internet searches appears to be decreasing. Pain, preanesthesia evaluation, anesthesia and outcome and side effects of anesthesia are the critical areas that anesthesiologists should focus on to address the increasing concerns.
背景
由于目前大众对麻醉的总体关注度尚不清楚，我们分析了互联网关键词搜索情况，以评估与手术和疼痛相比，大众对麻醉的总体关注度。
方法
使用谷歌搜索趋势分析工具调查了2004年至2010年与“麻醉”相关的关键词搜索趋势。调查了2004年至2010年在PubMed和Medline上被引用的关于麻醉的同行评审文章数量的趋势。使用谷歌关键词广告工具估算了麻醉、手术和疼痛方面的广告平均成本。还分析了其他常见搜索引擎的搜索结果。确定年份与相对搜索次数之间的相关性，p<0.05被认为具有统计学意义。
结果
谷歌搜索趋势分析工具显示，自2004年以来，“麻醉”关键词的搜索量有所下降（p<0.05）。同期，“麻醉副作用”的搜索量呈上升趋势，而“麻醉与安全”的搜索量呈下降趋势。“麻醉前”的搜索短语比“麻醉前准备”搜索更频繁，且“麻醉前”的搜索量呈上升趋势。以“疼痛”为关键词的搜索量在所示年份中稳步增加。虽然不同的搜索引擎可能提供不同的搜索结果总数（可用帖子），但与围手术期护理相关的一些常见关键词之间的搜索结果比例具有可比性，表明趋势相似。关于“麻醉”的同行评审手稿以及关于“麻醉与结局”的论文比例呈上升趋势。由于搜索流量相对较少，与疼痛或手术相关术语相比，麻醉相关术语的广告支出估计较少。
结论
通过互联网搜索衡量，大众对麻醉的总体关注度似乎在下降。疼痛、麻醉前评估、麻醉与结局以及麻醉副作用是麻醉医生应关注以应对日益增加的担忧的关键领域。
