In this study, we evaluated the effects of viewing an educational videotape about pediatric anesthesia on measures of parental knowledge of anesthesia and preoperative anxiety using a randomized, controlled design. During their routine preoperative visit, 85 parents of children scheduled to undergo ambulatory surgical procedures under general anesthesia were randomized to view either the experimental videotape about pediatric anesthesia or a control videotape with no medical content. Before and immediately after viewing the assigned videotape, parents completed measures of situational anxiety (State-Trait Anxiety Inventory-State), preoperative anxiety and need for information (Amsterdam Preoperative Anxiety and Information Scale), and anesthesia knowledge (Standard Anesthesia Learning Test). Repeated-measures analyses of variance showed that parents who viewed the experimental videotape showed a significant increase in anesthesia knowledge (P < 0.022) and a significant reduction in their state of anxiety (P < 0.031), anesthesia-specific anxiety, and need for information (P < 0.0001) compared with the control group. These results demonstrated that viewing a preoperative educational videotape about pediatric anesthesia can provide immediate educational and anxiolytic benefits for parents of children undergoing ambulatory surgery. The duration of these benefits remains to be determined.
In this study, we demonstrated the benefits of viewing an educational videotape about pediatric anesthesia on measures of parental knowledge of anesthesia and preoperative anxiety using a randomized, controlled design. We found that videotape viewing facilitated preoperative preparation and lessened preoperative anxiety.
在本研究中，我们采用随机对照设计，评估观看一段关于小儿麻醉的教育录像对家长麻醉知识及术前焦虑指标的影响。在患儿常规术前访视期间，85名计划接受全身麻醉下门诊手术的患儿家长被随机分组，分别观看关于小儿麻醉的实验录像或无医学内容的对照录像。在观看指定录像之前及之后，家长完成情境焦虑（状态-特质焦虑量表-状态）、术前焦虑及信息需求（阿姆斯特丹术前焦虑与信息量表）以及麻醉知识（标准麻醉学习测试）的测量。重复测量方差分析显示，与对照组相比，观看实验录像的家长麻醉知识显著增加（P < 0.022），其焦虑状态（P < 0.031）、麻醉特异性焦虑及信息需求显著降低（P < 0.0001）。这些结果表明，观看一段关于小儿麻醉的术前教育录像可为接受门诊手术患儿的家长带来即时的教育及抗焦虑益处。这些益处的持续时间仍有待确定。
在本研究中，我们采用随机对照设计，证明了观看一段关于小儿麻醉的教育录像对家长麻醉知识及术前焦虑指标的益处。我们发现观看录像有助于术前准备并减轻术前焦虑。
