Exclusion criteria: |
1. Absolute or relative contraindications to intrathecal anaesthesia (e.g. coagulation disorders, puncture site infection, severe spinal deformity, increased intracranial pressure). 2. hypertensive disorders during pregnancy, pre-eclampsia, eclampsia. 3. Known severe cardiovascular or respiratory diseases (e.g. cardiac function class III-IV, severe arrhythmia, moderate or higher pulmonary hypertension, poorly controlled asthma). 4. Preoperative uncontrolled hypertension (SBP > 160 mmHg) or hypotension (SBP < 90 mmHg). 5. Long-term use of medications that may affect heart rate and vascular tone (e.g., beta-blockers, calcium channel blockers). 6. Emergency surgery, multiple pregnancies, suspected macrosomia or placental abnormalities. 7. Other conditions that, in the judgement of the investigator, make participation in this study inappropriate. |
