研究目的: |
1主要目的 评估术中动-静脉CO2分压间隙(P(v-a)CO?)与PPCs高风险患者手术后7天内术后肺部并发症(PPCs)综合发生率(包括轻度和重度PPCs)的相关性分析。 2 次要目的 (1)比较Pv-aCO2在预测PPCs的风险分级和术后并发症的价值; (2)验证Pv-aCO2阈值对再插管、ICU入住时长、住院费用等次要临床结局的预测价值。 |

|
Objectives of Study: |
1. Primary Objective: To evaluate the association between intraoperative venous-to-arterial carbon dioxide partial pressure difference (P(v-a)CO?) and the composite incidence of postoperative pulmonary complications (PPCs)—including both mild and severe PPCs—within 7 days after surgery in high-risk patients. 2. Secondary Objectives: (1) To compare the predictive value of P(v-a)CO? for PPCs risk stratification and postoperative complications; (2) To assess the predictive value of P(v-a)CO? threshold for secondary clinical outcomes, including reintubation, ICU length of stay, and hospitalization costs. |

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: |
本研究的数据采集包括纸质版病例报告表(Case Record Form, CRF)与电子数据采集系统(Electronic Data Capture, EDC)两部分。研究期间所有数据均由经过培训的研究人员依据受试者原始记录及时、准确、完整地填写入CRF表,并定期录入至EDC系统。EDC系统具有权限管理、数据验证及数据修改追踪等功能,确保数据的完整性、准确性及可追溯性。数据管理过程中采用双人核查机制,对录入数据进行逻辑校验、缺失值核查及异常值处理。在研究结束后,数据将进行数据库锁定,保存至安全加密的研究数据库中,并由主要研究者及数据管理员共同监管。所有研究数据均按照国家相关法规及伦理要求保存,并保障受试者的隐私与数据安全。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data collection for this study consists of two components: a paper-based Case Record Form (CRF) and an Electronic Data Capture (EDC) system. All clinical and laboratory data will be recorded promptly, accurately, and completely by trained research personnel using the CRF, and subsequently entered into the EDC system. The EDC system supports user access control, data validation, and audit trails to ensure data integrity, accuracy, and traceability. A dual-entry and verification process will be implemented, including logic checks, missing data queries, and outlier detection. At the conclusion of the study, the database will be locked and securely stored in an encrypted research server, overseen by both the principal investigator and the data management team. All data will be maintained in accordance with national regulations and ethical requirements, with full protection of subject privacy and data confidentiality. |
