• Date of first enrollment: 06/11/2024
• Target sample size: 60
• Study type: Interventional

Intervention(s)

Automatic controlled group(experimental group): Circulatory agonists and intravenous fluids are automatically delivered by the automated system.

2. Heart rate during the evaluation period
3. Doses of infusion fluids used during the evaluation period
4. Dose of phenylephrine used during the evaluation period
5. Urine volume
6. Bleeding volume
7. Water balance
8. Percentage of time during surgery when sedation, analgesia, and muscle relaxation were adequately maintained
9. Percentage of time during surgery when both sedation and analgesia were adequately maintained
