研究目的:

主要研究目的 探讨术前临界闭合压(CrCP)与老年腹腔镜结直肠癌手术患者术中低血压严重程度的相关性,评价术前CrCP对术中低血压负荷的预测价值。 次要研究目的 (1)比较不同CrCP水平患者术中血管活性药物使用剂量及使用率的差异; (2)分析不同CrCP患者术后不良反应的发生情况; (3)明确术前CrCP是否可作为老年腹腔镜结直肠癌手术患者围术期风险分层的有效指标。  

Objectives of Study:

Primary Study Objective: To explore the correlation between preoperative critical closing pressure (CrCP) and the severity of intraoperative hypotension in elderly patients undergoing laparoscopic colorectal cancer surgery, and to evaluate the predictive value of preoperative CrCP for intraoperative hypotension burden. Secondary Study Objectives: (1) To compare the differences in dosage and utilization rate of intraoperative vasoactive drugs among patients with different CrCP levels. (2) To analyze the incidence of postoperative adverse reactions in patients with different CrCP levels. (3) To clarify whether preoperative CrCP can serve as an effective indicator for perioperative risk stratification in elderly patients undergoing laparoscopic colorectal cancer surgery.

测量指标:

Outcomes:

指标中文名:

临界闭合压

指标类型:

主要指标

Outcome:

Intraoperative hypotension

Type:

Primary indicator

测量时间点:

麻醉诱导前 30 min 内,于麻醉准备间完成

测量方法:

患者取平卧位,超声引导下桡动脉穿刺置管后,安静休息 10 min, 记录平稳状态下基础桡动脉有创平均动脉压MAP(P1),上臂袖带慢慢加压,直到桡动脉波形刚好完全消失那一刻的袖带压力(P2),CrCP=P1-P2,重复3次,每次间隔1分组,取平均值。

Measure time point of outcome:

Completed in the anesthesia preparation room within 30 minutes before anesthesia induction

Measure method:

Supine position, After ultrasound-guided radial artery catheterization, all subjects rested quietly for 10 minutes. The baseline invasive mean arterial pressure (MAP) of radial artery at steady state was recorded as P1. The upper arm cuff was inflated slowly until the radial artery waveform completely disappeared, and the corresponding cuff pressure was defined as P2. CrCP was calculated as CrCP = P1-P2. The measurement was repeated three times at 1-minute intervals, and take the average.

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:

1. 病例观察记录表:采用统一设计的纸质病例记录表,逐项如实填写患者基线资料、术前临界闭合压检测结果、术中血压变化及术中低血压发生情况等临床研究信息,现场核对确认,保证记录内容完整准确。 2. 电子采集管理系统:将纸质记录表信息统一录入专用电子数据管理系统,完成数据电子化归档、分类整理与储存。实行专人负责、双人交叉复核,设置数据访问权限,规范数据调取与使用流程,严格保护受试者隐私,全程把控数据质量,确保研究数据真实规范、可核查溯源。

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

1.Case Observation Record Form: Uniformly designed paper-based record forms were adopted. Clinical research information including patients' baseline data, preoperative critical closing pressure measurements, intraoperative blood pressure changes and incidence of intraoperative hypotension was truthfully filled in item by item. On-site verification was performed to ensure complete and accurate records.Electronic. 2.Collection and Management System: All data from paper forms were uniformly entered into a dedicated electronic data management system for electronic filing, sorting and storage. The data management was assigned to designated staff with double-person cross-check. Data access permissions were set to standardize data retrieval and application procedures. The privacy of participants was strictly protected, and data quality was fully monitored throughout the whole process to guarantee the authenticity, standardization, traceability and verifiability of research data.
