研究目的:

本研究团队发现待产产妇在宫缩期和宫缩间期呼吸频率和呼吸幅度有明显改变。宫缩期呼吸改变,一般表现为呼吸频率增快、呼吸幅度加大,或者单一的呼吸频率或者呼吸幅度的改变。因此,本研究团队假设产妇在宫缩期和宫缩间期的呼吸变异情况可能能有效预测产妇宫缩时的疼痛。  

Objectives of Study:

Our research team observed significant alterations in both respiratory rate and amplitude during contraction and inter-contraction phases in parturient women prior to labor analgesia administration. These phase-dependent respiratory variations were abolished following the establishment of effective labor analgesia. Based on these findings, we hypothesize that real-time monitoring of respiratory variability between uterine contraction and inter-contraction phases may dynamically reflect the intensity of labor pain during parturition.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

由于研究期间,所有产妇无法看到监护仪,对于所监测的项目,如SPI、RRV、RAV、HR等监测指标未知。此外,SPI、HR以及产妇呼吸波形的截取都由一位研究助手记录和处理。麻醉医生对所记录的内容未知。因此本研究为双盲研究。

Blinding:

In the study period, all parturients are unable to see the monitors, and the monitoring items, such as SPI, RRV, RAV, and HR, are blinded to them. Additionally, the recording and processing of SPI, HR, and the mother's respiratory waveform were handled by a research assistant. The anesthesiologist was unaware of the recorded data. So the study was a double-blind design.

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:

由一位研究助理使用病例记录表记录所有数据,并通过监护仪下载所有截取的呼吸波形。完成每一例病例收集后一并交由数据管理员进行数据录入、波形分析和数据统计。数据录入采用Excel格式。

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

All data are recorded by a research assistant using a case record form, and all captured respiratory waveforms were downloaded through the monitor. After the collection of each case, the data were handed over to the data administrator for data entry, waveform analysis and data statistics. Data entry is in Excel format.
