研究目的:

儿童腺样体肥大是儿科常见疾病,可影响患儿的生理与认知发育,甚至诱发早期心血管系统病理改变。该疾病与过敏性鼻炎、鼻窦炎等儿科疾病的发生发展密切相关,对儿童健康构成显著威胁。腺样体切除术是治疗儿童腺样体肥大的一线方案,可有效解除上气道阻塞、改善呼吸功能。由于患儿认知发展尚不完善且依赖性强,约60%的儿童在围术期出现术前焦虑。此类焦虑可激活机体应激反应系统,促使糖皮质激素分泌增加,进而导致术后感染风险上升、伤口愈合延迟,对术后恢复造成不良影响。当前临床应对儿童术前焦虑主要依赖药物干预,然而适用于儿童的抗焦虑药物种类较为有限。因此,迫切需要一种在儿科麻醉中兼具高安全性与高效性的新方法,以确保患儿在围术期获得最佳麻醉效果,最大限度降低相关风险与并发症,为其手术安全与术后康复提供可靠保障。 右美托咪定可通过激活蓝斑与脊髓的α2受体发挥镇静、镇痛作用,诱导类生理性睡眠状态。相比其他常用镇静药物,其对肾功能影响甚微,呼吸抑制轻微,且具备可唤醒特性,便于患儿配合操作。若经鼻腔给药不仅能快速起效,还可减少其他途径给药的风险与不适,为儿童治疗提供一种更为安全、有效的选择。 本项目旨在深化DHNS用于儿童术前用药的相关研究,采用双盲设计,纳入拟行腺样体切除术的患儿,随机分配至生理盐水组或不同剂量右美托咪定鼻喷雾剂组。通过监测血氧饱和度、心率、脑电双频指数等生理指标,结合不良反应发生情况,系统评价各组镇静方案的有效性与安全性,以期为临床诊疗提供新依据。  

Objectives of Study:

5Pediatric adenoid hypertrophy is a prevalent condition that can impair physiological and cognitive development, and even induce early pathological changes in the cardiovascular system. This disease is closely associated with the onset and progression of other pediatric disorders such as allergic rhinitis and sinusitis, posing a significant threat to children's health. Adenoidectomy serves as the first-line treatment, effectively relieving upper airway obstruction and improving respiratory function. However, due to incomplete cognitive development and high dependency, approximately 60% of children experience preoperative anxiety. Such anxiety activates the body's stress response system, increasing glucocorticoid secretion, which subsequently elevates the risk of postoperative infections and delays wound healing, adversely affecting recovery. Current clinical management of pediatric preoperative anxiety primarily relies on pharmacological interventions; however, the variety of anxiolytic drugs suitable for children is limited. Therefore, there is an urgent need for a novel approach in pediatric anesthesia that combines high safety with high efficacy, ensuring optimal anesthetic outcomes and minimizing risks and complications to provide reliable for surgical safety and postoperative rehabilitation. Dexmedetomidine exerts sedative and analgesic effects by activating α2 receptors in the locus coeruleus and spinal
