儿童全麻前焦虑是麻醉医生在日常工作中经常遇到的实际问题。孩子进入陌生环境、与父母分离、面对面罩或静脉穿刺时，常会出现哭闹、抗拒、心率增快和诱导配合困难。传统方法包括术前宣教、父母陪伴、玩具或视频分散注意力，以及必要时使用镇静药物，但这些方法并不总是理想。
那么，虚拟现实技术能否作为一种非药物干预，真正减轻儿童全麻前焦虑？它只是一个有趣的玩具，还是有可能成为儿科麻醉术前准备流程中的实用工具？
下面这篇文献将回答这个问题。

文献的英文摘要要点
Objective: To evaluate the effectiveness of virtual reality (VR) interventions in reducing preoperative anxiety in pediatric patients undergoing general anesthesia, and provide evidence to inform clinical decision-making.
Methods: A comprehensive search was performed across PubMed, Embase, and the Cochrane Library, covering publications from inception to June 7, 2025. The study included randomized clinical trials (RCTs) of VR-based interventions, both immersive and non-immersive, compared with standard treatments or placebo controls.
