干预措施:

右美托咪定盐酸鼻喷雾剂 本研究中使用的右美托咪定盐酸鼻喷雾剂由江苏恒瑞医药股份有限公司生产。给药前应清洁儿童的鼻腔分泌物,保持鼻腔干燥。让儿童取坐位,头部稍前倾。将已激活的鼻喷雾泵保持直立,喷嘴以与鼻腔相同的角度插入鼻孔,一次性按压泵体底部完成单侧或双侧鼻内喷雾。该药物溶液有两种浓度规格(I型:500 μg/ml,每喷25 μg;II型:300 μg/ml,每喷15 μg)。总剂量按2 μg/kg计算,根据体重选择适当规格进行分次喷雾。整个给药操作应在2分钟内完成。本产品为一次性使用装置,剩余药液必须按照医疗废物规范处理。

干预措施代码:

Intervention:

Dexmedetomidine Hydrochloride Nasal Spray Dexmedetomidine hydrochloride nasal spray used in this study is produced by Jiangsu Hengrui Pharmaceutical Co., Ltd. Before administration, nasal secretions of the children should be cleaned to keep the nasal cavity dry. The child is placed in a sitting position with the head slightly forward. The activated nasal spray pump is kept upright, the nozzle is inserted into the nostril at the same angle as the nasal cavity, and the pump body is pressed to the bottom at one time to complete unilateral or bilateral intranasal spray. The drug solution is available in two concentration specifications (Type I: 500 μg/ml, 25 μg per spray; Type II: 300 μg/ml, 15 μg per spray). The total dose is calculated at 2 μg/kg, and the appropriate preparation is selected for fractional spray according to the body weight. The entire administration operation should be completed within 2 minutes. This product is a single-use device, and the remaining drug solution must be disposed of in accordance with the specifications for medical waste.

是否共享原始数据:

IPD sharing

是Yes

共享原始数据的方式(说明:请填入公开原始数据日期和方式,如采用网络平台,需填该网络平台名称和网址):

本研究尚未启动,暂无原始数据;预计共享时间为试验结束后 6 个月内;共享方式为通过 ResMan 平台(www.medresman.org.cn)共享,数据仅可在线浏览,如需下载可向研究负责人申请获取。

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):

This study has not yet started, and there is no raw data available; it is expected to be shared within 6 months after the end of the trial; the data will be shared through the ResMan platform (www.medresman.org.cn), and can only be viewed online. If download is required, an application can be submitted to the principal investigator to obtain it.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

采用病例记录表(CRF) + ResMan(www.medresman.org) 基于互联网的电子数据采集和管理系统(EDC)进行数据采集与管理。所有数据均通过病例报告表(CRF)录入和管理,确保其源自临床试验的源文件,以保证数据的准确性、完整性、可读性和及时性。对源数据的修改必须可追溯,并需注明修改原因。主要研究者将指定专人负责CRF录入并监督数据质量。所有CRF数据将由两名独立研究人员进行复核,以减少录入错误,并使用电子数据采集(EDC)系统进行数据管理,该系统具备实时数据验证规则。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Use Case Report Forms (CRF) and ResMan (www.medresman.org.cn) internet-based electronic data capture and management system (EDC) for data collection and management.All data are entered and managed using the case report form (CRF), which is ensured to be derived from the source documents of the clinical trial to guarantee its accuracy, completeness, readability and timeliness. Modifications to the source data must be traceable and the reasons must be indicated. The principal investigator will assign a special person to be responsible for CRF entry and supervise the data quality. All CRF data will be double-checked by two independent researchers to reduce entry errors, and the electronic data capture (EDC) system will be used for data management with real-time data validation rules.
