研究目的: |
本研究拟探索不同吸入氧浓度对施行腔镜下胃减容手术的肥胖患者术后氧合功能的影响,旨在寻求既能满足肥胖患者术中动脉血氧分压和氧合,同时降低患者围术期肺部损伤和肺部并发症的吸入氧浓度。有利于对肥胖患者精确实施术中肺保护性通气策略,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 explore the effects of different inhaled oxygen concentrations on postoperative oxygenation function in obese patients undergoing endoscopic gastric volume reduction surgery, with the aim of seeking inhaled oxygen concentrations that can meet the intraoperative arterial oxygen partial pressure and oxygenation needs of obese patients while reducing perioperative lung injury and complications. It is beneficial to accurately implement intraoperative lung protective ventilation strategies for obese patients, reduce the incidence of postoperative pulmonary complications, reduce hospitalization time and medical expenses, 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): |
按照随机数字表法进行分组,将分组情况装入顺序编号、不透光、 密封的信封中,选择符合纳入标准和排除标准的患者顺序编号,再打开相应编号的信封,按信封内的分组方案进行干预,若出现患者手术终止,后一位患者接着纳入上一编号组别给予相应干预。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
According to the random number table method, group the patients into sequentially numbered, opaque, and sealed envelopes. Select the patient sequence numbers that meet the inclusion and exclusion criteria, and then open the corresponding numbered envelopes. Intervene according to the grouping scheme in the envelopes. If the patient's surgery is terminated, the next patient will be included in the previous numbered group for corresponding intervention. |

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. |
