研究目的:

评估右美托咪定对腹腔镜袖状胃切除术患者术后恶心呕吐(PONV)发生率及严重程度的影响,同时观察其对术后疼痛、镇静水平、恢复质量及安全性的作用,为优化该类患者的围术期管理提供循证医学依据。  

Objectives of Study:

To evaluate the effect of dexmedetomidine on the incidence and severity of postoperative nausea and vomiting (PONV) after laparoscopic sleeve gastrectomy, and to observe its impact on postoperative pain, sedation level, recovery quality and safety, so as to provide evidence-based medical evidence for optimizing perioperative management of such patients.

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:

所有研究数据将使用双轨制进行管理与保存:病例报告表(CRF)采用纸质原件与电子扫描件同步归档(由两名研究人员独立进行数据录入与核对)。

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

All research data will be managed and saved using a dual-track system: the case report form (CRF) will be filed simultaneously with the original paper copy and the electronic scanned copy (data entry and verification will be carried out independently by two researchers).
