Objective: To investigate the application effect of ropivacaine spinal anesthesia on cesarean section and its influence on the quality of life of pregnant women.Methods: 200 pregnant women who received cesarean section in the hospital from January 2016 to February 2017 were randomly divided into observation group and control group. The control group was treated with bupivacaine spinal anesthesia, and the observation group was treated with ropivacaine spinal anesthesia. The anesthetic effects were observed and compared between the two groups.Results: The overall anesthesia efficiency was 96.00% in the observation group and 89.00 % in the control group, and the difference between the two groups was statistically significant (P＜0.05). The average score of the quality of life in the observation group was 78.85 ± 4.50, which was significantly higher than that in the control group (67.38 ± 4.07) (P＜0.05). The overall anesthesia satisfaction in the observation group was 95 %, which was significantly higher than that in the control group (83.00 %) (P＜0.05).Conclusion: The ropivacaine spinal anesthesia approach in cesarean section can improve the excellent rate of anesthesia in pregnant women, and improve their quality of life and anesthesia satisfaction. It is worthy of clinical promotion.
