研究目的:

1.主要目标:验证与常规护理相比,术前实施定制化VR沉浸式干预能否显著降低骨创伤患儿的术前焦虑视觉模拟量表评分。 2.次要目标:评估VR干预对围术期转归的改善作用, 包括: 改善围术期应激相关激素,减轻术后早期疼痛、改善术后睡眠质量、减少苏醒期谵妄发生率、减少围术期麻醉诱导用药量、提升术后度、缩短术后首次下床时间、住院时间等, 减少治疗费用等。 3.机制探索目标:阐明VR干预调控围术期应激反应的生理学机制。具体假设:VR干预通过快速增强迷走神经张力(表现为高频心率变异性升高LF/HF)、改善外周循环 (表现为血流灌注指数升高 PI),交感兴奋引起α受体介导的外周血管强烈收缩,导致PI值显著下降。这是反映身体处于“战斗或逃跑”状态时外周循环关闭的直观指标。在术前焦虑患儿身上,PI值下降会非常明显。从而优化患儿的自主神经平衡与心血管应激反应模式,这种优化的生理状态是临床获益的中介。  

Objectives of Study:

1. Primary Objective: To verify whether, compared with conventional care, preoperative customized VR immersive intervention can significantly reduce the preoperative Visual Analog Scale (VAS) anxiety score in children with bone trauma. 2. Secondary Objectives: To evaluate the improvement effects of VR intervention on perioperative outcomes, including: amelioration of perioperative stress-related hormones; reduction of early postoperative pain; improvement of postoperative sleep quality; reduction in the incidence of emergence delirium; reduction of perioperative anesthetic induction dosage; improvement of postoperative recovery quality; shortening of time to first ambulation and length of hospital stay; and reduction of treatment costs. 3. Mechanistic Exploration Objective: To elucidate the physiological mechanisms by which VR intervention regulates the perioperative stress response. The specific hypothesis is that VR intervention rapidly enhances vagal tone (manifested as increased high-frequency heart rate variability [HF-HRV] and decreased LF/HF ratio) and improves peripheral circulation (manifested as an increased perfusion index, PI). Sympathetic excitation causes α‑receptor‑mediated intense peripheral vasoconstriction, leading to a marked decrease in PI. This is an intuitive indicator of peripheral circulatory shutdown when the body is in a "fight‑or‑flight" state. In children with preoperative anxiety, the decrease in PI is very pronounced. Consequently, VR intervention optimizes the pattern of autonomic balance and cardiovascular stress response, and this optimized physiological state serves as a mediator of clinical benefits.
