研究目的: |
本研究旨在探讨视神经鞘直径(Optic Nerve Sheath Diameter,ONSD)与左心室射血时间积分(Velocity Time Integral,VTI)在子痫前期孕妇围剖宫产期心功能评估及容量管理中的联合应用价值。 通过联合测量和分析这两个指标,以期为临床提供更全面、准确的心功能评估手段和容量管理策略,从而优化子痫前期孕妇围剖宫产期的临床管理,改善母婴预后。 |

|
Objectives of Study: |
This study aims to explore the combined application value of Optic Nerve Sheath Diameter (ONSD) and Velocity Time Integral (VTI) of the left ventricle in assessing cardiac function and managing fluid volume during the peri-cesarean section period in pregnant women with preeclampsia. By jointly measuring and analyzing these two indicators, we hope to provide more comprehensive and accurate means for cardiac function assessment and strategies for fluid volume management in clinical practice, thereby optimizing the clinical management of pregnant women with preeclampsia during the peri-cesarean section period and improving maternal and neonatal outcomes. |

Inclusion criteria |
1.Preeclampsia patients with an ASA (American Society of Anesthesiologists) physical status classification of III and aged between 18 and 45 years old. 2.Patients meeting the diagnostic criteria for preeclampsia, which include the onset of systolic blood pressure >=140 mmHg and/or diastolic blood pressure >=90 mmHg after 20 weeks of gestation, accompanied by proteinuria >=0.3 g/24 h or random proteinuria ≥ (+), or, in the absence of proteinuria, the presence of any of the following conditions: thrombocytopenia (platelet count <100×10^9/L), liver dysfunction (serum transaminase levels more than twice the normal value), renal dysfunction (serum creatinine >1.1 mg/dL or an increase of more than 0.5 mg/dL from pre-pregnancy levels), pulmonary edema, or newly developed cerebral or visual dysfunction. |

|
排除标准: |
1、合并其他心血管疾病、颅内病变、眼部疾病等可能影响 ONSD 或心功能的疾病; 2、对麻醉药物过敏或存在麻醉禁忌证; 3、入组前3个月以内曾参加过其他临床试验及正在参加其他临床试验的产妇; 4、根据试验负责医师判断,实施试验可能会使受试者危险性增加、或可能无法获得足够试验数据的产妇。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1.Patients with concurrent cardiovascular diseases, intracranial lesions, ocular diseases, or other conditions that may affect ONSD or cardiac function; 2.Patients with allergies to anesthetic drugs or existing contraindications to anesthesia; 3.Maternal participants who have participated in other clinical trials within the past three months prior to enrollment or are currently participating in other clinical trials; 4.Maternal participants for whom, in the judgment of the trial's responsible physician, participation in the trial may increase the risk to the subject or may result in insufficient trial data being obtained. |
