Objectives of Study: |
To evaluate the effectiveness of using fingertip pulse oximetry waveform changes as an early warning for hypotension after spinal anesthesia during cesarean section, and to assess the effectiveness of prophylactic titration of norepinephrine in maintaining the blood pressure stability of the parturient under the guidance of this early warning signal |

|
盲法: |
对受试者设盲:由于两组干预策略存在本质差异,预警干预组在特定生理信号出现时预防性给药,常规对照组仅在低血压发生后治疗性给药,因此无法对接受麻醉的患者以及在手术室中负责管理患者的麻醉医生、护士实施设盲。他们知晓患者所属的研究组别。对数据分析者设盲:为确保主要结局(低血压发生)和次要结局(药物用量等)评估的客观性研究者不设盲法,对负责数据提取、整理及统计分析的研究人员将对患者的分组信息保持盲态。原始监测数据(血压、心率、PPG波形)将被匿名化处理,在分析数据集中仅以研究编号和时序标记,不包含组别信息。待所有数据分析完成后,再进行揭盲与结果解读。 |
|
Blinding: |
Blinding of participants: Due to the inherent differences between the two intervention strategies—the early-warning intervention group receives prophylactic medication upon the appearance of specific physiological signals, while the conventional control group receives therapeutic medication only after hypotension occurs—it is not possible to blind the patients undergoing anesthesia, or the anesthesiologists and nurses managing the patients in the operating room. They are aware of the study group to which each patient belongs. Blinding of data analysts: To ensure objectivity in the assessment of primary outcomes (e.g., occurrence of hypotension) and secondary outcomes (e.g., dosage of medications), the investigators are not blinded. However, researchers responsible for data extraction, organization, and statistical analysis will remain blinded to the patients’ group allocation. Raw monitoring data (blood pressure, heart rate, PPG waveforms) will be anonymized; in the analytical dataset, only study IDs and time series markers will be included, with no group information. Unblinding and interpretation of results will be performed only after all data analyses are completed. |
