We designed an interactive animated video that provides a basic explanation-including the risks, benefits, and alternatives-of anesthetic procedures. We hypothesized that this video would improve patient understanding of anesthesia, reduce anxiety, and shorten the interview time.
Two hundred eleven patients scheduled for cancer surgery under general anesthesia or combined general and epidural anesthesia, who were admitted at least 1 day before the surgery, were randomly assigned to the video group (n = 106) or the no-video group (n = 105). The patients in the video group were asked to watch a short interactive animation video in the ward. After watching the video, the patients were visited by an anesthesiologist who performed a preanesthetic interview and routine risk assessment. The patients in the no-video group were also visited by an anesthesiologist, but were not asked to watch the video. In both groups, the patients were asked to complete the State-Trait Anxiety Inventory and a 14-point scale of knowledge test before the anesthesiologist's visit and on the day of surgery. We also measured interview time.
There was no demographic difference between the 2 groups. The interview time was 34.4% shorter (video group, 12.2 ± 5.3 minutes, vs. no-video group, 18.6 ± 6.4 minutes; 95% confidence interval [CI] for the percentage reduction in time: 32.7%- 44.3%), and knowledge of anesthesia was 11.6% better in the video group (score 12.5 ± 1.4 vs. no-video group score 11.2 ± 1.7; 95% CI for the percentage increase in knowledge: 8.5%-13.9%). However, there was no difference in preanesthetic anxiety between the 2 groups.
Our short interactive animation video helped patients' understanding of anesthesia and reduced anesthesiologists' interview time.
我们设计了一个互动式动画视频，对麻醉程序的风险、益处和替代方案进行基本解释。我们假设该视频将提高患者对麻醉的理解，降低焦虑，并缩短访谈时间。
我们将 211 名拟接受全身麻醉或全身与硬膜外联合麻醉的癌症手术患者随机分配至视频组（n = 106）或非视频组（n = 105）。视频组患者在病房观看简短的互动动画视频，观看后由麻醉医师进行麻醉前访视和常规风险评估。非视频组患者也由麻醉医师进行访视，但不要求观看视频。在两组中，患者均在麻醉医师访视前和手术当天完成状态-特质焦虑量表和 14 分制知识测试。我们还测量了访谈时间。
两组患者的人口统计学差异无统计学意义。视频组的访谈时间缩短了 34.4%（视频组，12.2 ± 5.3 分钟，非视频组，18.6 ± 6.4 分钟；95%置信区间[CI]为时间减少百分比：32.7%-44.3%），对麻醉知识的掌握程度提高了 11.6%（视频组评分 12.5 ± 1.4，非视频组评分 11.2 ± 1.7；95%CI 为知识增加百分比：8.5%-13.9%）。然而，两组患者的麻醉前焦虑程度无差异。
我们的简短互动动画视频有助于患者理解麻醉，并缩短麻醉医师的访谈时间。
