Brief Summary

There is a trend that breast surgery can be done with peripheral nerve blockade and intravenous sedation, which reduces the side effects of general anesthesia such as nausea and vomiting, intubation discomfort and postoperative pain. The distribution of breast nerves is complex. Common nerve block methods are paravertebral blocks and pectoral nerve blocks. By monitoring the patient's heart rate variability change and measuring the patient's parasympathetic tone, the analgesic drug can be administered according to the patient's individual differences to avoid insufficient or excessive analgesic dose. The aim of this proposal is a prospective randomized controlled clinical trial is designed to evaluate changes in analgesia nociception index (ANI), surgical pleth index (SPI), postoperative opioid demand, and pain scores between patients who received regional anesthesia and those without in breast surgery patients under non-intubated surgery.
