研究目的: |
通过解构产时剖宫产的异质性风险来源,量化产妇基础病理风险与阴道试产过程风险对母婴不良结局的独立贡献度,为促进阴道试产降低剖宫产率提供依据。 |

|
Objectives of Study: |
By deconstructing the heterogeneous risk sources of intrapartum cesarean section, this study quantifies the independent contributions of maternal basic pathological risks and intrapartum vaginal trial labor risks to adverse maternal and infant outcomes, so as to provide evidence for promoting vaginal trial labor and reducing the cesarean section rate. |

Exclusion criteria: |
1. Maternal factors Severe pelvic deformity resulting in absolute cephalopelvic disproportion (anterior-posterior diameter of the pelvic inlet ≤8 cm), active bleeding from uterine rupture, active genital herpes lesions obstructing the birth canal, invasive cervical cancer (clinical stage ≥IIB requiring immediate pregnancy termination and radiotherapy), uncontrollable massive obstetric hemorrhage (ineffective uterotonics with blood loss >1500 mL or sudden Hb decrease >3 g/dL), NYHA class III–IV cardiac dysfunction. 2.Fetal factors Transverse lie or shoulder presentation (regardless of gestational age), mentoposterior position (mechanical obstruction due to face presentation), compound presentation with irreducible umbilical cord prolapse and fetal heart rate <60 bpm, persistent fetal heart rate abnormalities. 3.Placental and umbilical cord factors Central placenta previa with active massive hemorrhage (blood loss >1500 mL), grade IV placental abruption (abruption area >50% complicated by DIC or uteroplacental apoplexy), rupture of vasa previa in velamentous insertion (vaginal bleeding plus sudden fetal heart rate deceleration), vasa previa (uncorrected position anterior to the presenting part). 4.Special infectious and medical contraindications Uncontrolled HIV infection (viral load >1000 copies/mL without standard antiretroviral therapy), active tuberculous meningitis (to avoid brain herniation caused by intracranial pressure fluctuations during labor), preeclampsia or severe preeclampsia complicated by organ injury (cerebrovascular accident, HELLP syndrome, or acute renal failure). 5.Women without pregnancy complications such as diabetes mellitus, hypertension, or thyroid disorders;without complications during labor induction including fetal distress (per FIGO cardiotocography criteria), intrapartum fever (≥38°C), or premature rupture of membranes >24 hours;who underwent cesarean section only due to failed induction (ineffective uterine contractions or arrested cervical dilation). |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
This study is a cohort study based on the medical record data from the hospital's HIS system. The data content and data collection methods do not cause harm or adverse consequences to patients. The data acquisition process complies with the hospital's data usage specifications and scientific research data usage regulations. The Information Department processes patients' information such as name, ID card number, and contact information. Meanwhile, in accordance with the principle that scientific research data shall not leave the hospital, the data is analyzed and used on the hospital's internal network, which avoids the risk of data and patients' medical record information leakage and conforms to ethical standards. |
