研究目的:

本研究旨在通过一项前瞻性、双盲、随机对照试验,探讨预防性雾化吸入盐酸戊乙奎醚(PHC)对行腹腔镜袖状胃切除术(LSG)的肥胖患者在气腹期间呼吸力学的影响,以及盐酸戊乙奎醚(PHC)雾化吸入对肥胖合患者腹腔镜术后肺功能的保护作用,验证肺保护作用机制,为 PHC 在肥胖患者围手术期肺保护中的临床应用提供依据。探讨有利于对肥胖患者完善围术期肺保护策略,加速术后恢复,降低患者术后肺部并发症的发生率,减少住院时间与医疗花费,提高患者及家属满意度。  

Objectives of Study:

This study aims to investigate the effects of prophylactic nebulized scopolamine hydrobromide on respiratory mechanics during pneumoperitoneum in obese patients undergoing laparoscopic sleeve gastrectomy, as well as the protective effects of nebulized scopolamine hydrobromide on postoperative pulmonary function in obese patients. It seeks to validate the mechanisms of pulmonary protection and provide a basis for the clinical application of PHC in perioperative pulmonary protection for obese patients. The study also explores strategies to enhance perioperative pulmonary protection, accelerate postoperative recovery, reduce the incidence of pulmonary complications, shorten hospital stays and medical costs, and improve patient and family satisfaction.

随机方法(请说明由何人用什么方法产生随机序列):

使用 SAS9.2 软件包(SAS Institute, Cary, NC, USA)按 1:1 的比例生成随机数字,区组大小为 6。整个研究过程中仅设计随机分组的研人员知晓分组情况,随机化结果密封在不透明信封中,并保存直至研究结束。

Randomization Procedure (please state who generates the random number sequence and by what method):

Generate random numbers in a 1:1 ratio using the SAS9.2 software package (SAS Institute, Cary, NC, USA), with a block size of 6. During the entire research process, only the researchers who designed the randomization were aware of the grouping situation. The randomization results were sealed in opaque envelopes and saved until the end of the study.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

双盲。整个研究过程中仅设计随机分组的研人员知晓分组情况在完成患者招募和随访,完成数据收集、录入及核对无误后经该研究人员允许后揭盲。

Blinding:

Double blind. During the entire research process, only the researchers who designed the random grouping were aware of the grouping situation. After completing patient recruitment and follow-up, completing data collection, entry, and verification without errors, the blinding was opened with the permission of the researchers.

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):

研究公开发表半年后,在ResMan(http://www.medresman.org.cn/uc/index.aspx)数据库中公布。

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

Half a year after the research was publicly published, it was published in ResMan( http://www.medresman.org.cn/uc/index.aspx )Published in the database.

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:

所有数据将在试验期间进行收集和存储,收集的数据记录在病例报告表中,并将被存储在电子数据库中,并备份到至少两个不同的地点。采用双人数据录入的方式避免和减少数据录入错误。数据管理员进行数据审核,完成数据质疑后锁定数据库,进行统计分析。

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

All data will be collected and stored during the trial period, recorded in the case report form, and stored in an electronic database with backups to at least two different locations. Adopting a dual person data entry method to avoid and reduce data entry errors. The data administrator conducts data review, locks the database after completing data questioning, and conducts statistical analysis.
