Cesarean section is an important procedure in modern obstetrics. It is of great significance to relieve the anxiety and tension of parturient and reduce the pain and complications of cesarean section patients during perioperative period. Because of the particularity of cesarean section, in order to avoid adverse effects on the fetus, it is particularly important to choose appropriate anesthesia methods and drugs. A meta-analysis found that dexmedetomidine can significantly reduce postoperative chills, while not increasing the incidence of nausea and vomiting during surgery, and there is no obvious bradycardia, and it can enhance sedation [Spinal anesthesia is more and more favored by obstetricians because of its quick effect, good muscle relaxation effect, completed block, and little effect on the fetus. However, maternal hypotension after spinal anesthesia is a common problem in clinical anesthesia, and its incidence is as high as 80% without any preventive measures [Hasanin et al. [According to the previous findings, continuous infusion of norepinephrine 0.04∼0.10 Lankadeva et al. [
