Abstract To analyze the anesthesia effect of epidural anesthesia assisted by sevoflurane inhalation of pregnant women with gestational hypertension during cesarean section, and to study its influence on the maternal hemodynamics. Methods: A total of 90 pregnant women with gestational hypertension who underwent cesarean section were selected and randomly divided into two groups (45 cases in each group) by random number table from March 2018 to March 2021. The women in the control group were anesthetized with epidural nerve block, while the women in the experimental group were anesthetized with epidural nerve block assisted by sevoflurane inhalation. The anesthesia effect and maternal hemodynamic change of the women before anesthesia (T1), 10 min after anesthesia (T2), fetal delivery (T3), and at the end of surgery (T4) were analyzed and compared between the two groups. Results: There were no significant differences in the intraoperative blood loss, the duration of fetal delivery, the fetal Apgar score at 1 min and 5min after born, and the umbilical cord blood pH value of the women between the two groups (P>0.05). The proportion of class III, II, and I of anesthesia of the women in the experimental group were 44.4%, 35.6%, and 20.0%, respectively. The proportion of class III, II, and I of anesthesia of the women in the control group were 20.0%, 40.0%, and 40.0%, respectively. The anesthesia effect of the women in the experimental group was significantly better than that of the women in the control group (χ2=7.290, P<0.05). There were no significant differences in the values of MAP, HR, CO, CI, and other hemodynamic indexes of the women at T1 between the two groups (P>0.05). The values of MAP, HR, CO, and CI of the women in the experimental group at T2, T3 and T4 were significantly higher than those of the women in the control group, and the incidence of adverse reactions during and after anesthesia (11.1%) of the women in the experimental group was significantly lower than that (28.9%) of the women in the control group (P<0.05). Conclusion: Epidural anesthesia assisted by sevoflurane inhalation for cesarean section of pregnant women with gestational hypertension during cesarean section can work rapidly with less adverse reactions, which can effectively stabilize the maternal hemodynamics during operation.
