Provision of preoperative information can alleviate patients' anxiety. However, the ideal method of delivering this information is unknown. Video information has been shown to reduce patients' anxiety, although little is known regarding the effect of preoperative multimedia information on anxiety in patients undergoing regional anaesthesia.
We randomized 110 patients undergoing upper or lower limb surgery under regional anaesthesia into the study and control groups. The study group watched a short film (created by the authors) depicting the patient's in-hospital journey including either a spinal anaesthetic or a brachial plexus block. Patients' anxiety was assessed before and after the film and 1 h before and within 8 h after their operation, using the Spielberger state trait anxiety inventory and a visual analogue scale.
There was no difference in state and trait anxiety between the two groups at enrollment. Women had higher baseline state and trait anxiety than men (P=0.02). Patients in the control group experienced an increase in state anxiety immediately before surgery (P<0.001), and patients in the film group were less anxious before operation than those in the control group (P=0.04). After operation, there was a decrease in state anxiety from baseline in both groups, but patients in the film group were less anxious than the control group (P=0.005).
Preoperative multimedia information reduces the anxiety of patients undergoing surgery under regional anaesthesia. This type of information is easily delivered and can benefit many patients.
提供术前信息可以减轻患者的焦虑。然而，传递这种信息的理想方法尚不清楚。视频信息已被证明可以降低患者的焦虑，尽管对于术前多媒体信息对接受区域麻醉的患者的焦虑的影响知之甚少。
我们将 110 例接受上肢或下肢手术的区域麻醉患者随机分为研究组和对照组。研究组观看了一部短片（由作者制作），描绘了患者在医院的旅程，包括脊髓麻醉或臂丛神经阻滞。使用 Spielberger 状态特质焦虑量表和视觉模拟量表评估患者在观看短片前后以及手术前 1 小时和术后 8 小时内的焦虑情况。
两组患者在入组时的状态和特质焦虑均无差异。女性的基线状态和特质焦虑均高于男性（P=0.02）。对照组患者在手术前即刻出现状态焦虑增加（P<0.001），而观察组患者在手术前的焦虑程度低于对照组（P=0.04）。手术后，两组患者的状态焦虑均较基线值下降，但观察组患者的焦虑程度低于对照组（P=0.005）。
术前多媒体信息可降低接受区域麻醉手术患者的焦虑。这种类型的信息易于传递，可以使许多患者受益。
