Objective To discuss the characteristics of delivery and anesthesia management of pregnant women with moderate to severe scoliosis, and to summarize the anesthesia implementation strategies for pregnant women with scoliosis. Methods Pregnant women with moderate to severe scoliosis admitted to West China Second University Hospital, Sichuan University between January 2020 and January 2022 were retrospectively included. The demography information, delivery mode, anesthesia implementation plan and other relevant data of the women were analyzed. Results A total of 9 women with moderate to severe scoliosis were included, with an average age of 29.9 years. The median (lower quartile, upper quartile) of the Cobb angle of the women was 42° (35°, 54°). There were 5 women with moderate to severe impairment of lung ventilation function, 1 woman with grade Ⅲ heart function, and 8 women with comorbidities. Among the 8 women who underwent cesarean section, 3 underwent general anesthesia, 4 underwent epidural block, and 1 underwent local anesthesia with enhanced sedation. One woman who chose vaginal delivery underwent epidural labor analgesia. All women passed the surgery or delivery period safely, with 5 transferred to the intensive care unit for further treatment after surgery, and 4 safely returned to the ward after surgery. All women recovered and were discharged. Eight fetuses survived, and 1 fetus underwent lethal induced abortion. Conclusions Pregnant women with moderate to severe scoliosis during pregnancy have poor tolerance to vaginal delivery due to severe malformations and organ dysfunction, especially cardiopulmonary dysfunction. Most of them terminate pregnancy through cesarean section. When making anesthesia decisions, it is important to carefully consider the women’s own condition and surgical risks.
