研究目的:

探索围术期在标准双联药物预防的基础上加用经皮耳迷走神经电刺激(taVNS)对于进一步降低单孔胸腔镜肺部分切除术患者术后恶心呕吐(PONV)的风险的有效性及安全性,并探讨其作为多模式止吐方案组成部分的额外效益。  

Objectives of Study:

To evaluate the efficacy and safety of adding perioperative transcutaneous auricular vagus nerve stimulation (taVNS) to standard dual antiemetic prophylaxis for further reducing the risk of postoperative nausea and vomiting (PONV) in patients undergoing uniportal video-assisted thoracoscopic partial lung resection and to explore its additional benefits as a component of a multimodal antiemetic strategy.

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:

本研究采用纸质病例报告表(CRF)进行数据采集。研究者根据原始病历资料及时、完整、准确地填写CRF。数据录入采用双人双录入方式,录入完成后进行一致性核查。所有数据由主要研究者或其指定人员负责管理,确保数据完整性和保密性。

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

In this study, paper case report forms (CRF) were used for data collection. The researchers filled in the CRF in a timely, complete and accurate manner based on the original medical records. Data entry is conducted in a double-person double-entry manner. After the entry is completed, consistency verification is carried out. All data are managed by the principal researcher or the person designated by him/her to ensure data integrity and confidentiality.
