Objective:To investigate the efficacy of maintenance electroconvulsive therapy (MECT) combined with quetiapine treatment for manic episodes of bipolar disorder.Methods:A total of 103 patients with manic episodes of bipolar disorder received treatment in Kangci Hospital of Jiaxing from January 2019 to August 2020 and were included in this study. They were randomly divided into observation ( n = 46) and control groups ( n = 57). The observation group was given MECT combined with quetiapine treatment and the control group was treated with magnesium valproate sustained-release tablets combined with quetiapine. All patients received 4 weeks of treatment. Clinical efficacy, total hospital cost, drug cost during hospitalization, drug proportion, adverse reactions, and scores of the Bech-Rafaelsdn Mania Rating Scale and the Wisconsin Card Sorting Test pre- and post-treatment were compared between the two groups. Results:After 4 weeks of treatment, total response rate was significantly higher in the observation group than in the control group [76.09% (35/46) vs. 56.14% (32/57), χ2 = 4.45, P < 0.05]. In the observation group, total hospital cost, drug cost during hospitalization, and drug proportion were (16074.52 ± 1019.81) yuan, (1374.52 ± 619.81) yuan, and 8.70% respectively, which were not significantly different from those in the control group [(15618.14 ± 1550.34) yuan, (1261.14 ± 750.34) yuan, 10.53%, t = 1.71, 0.82, χ2 = 0.09, all P > 0.05]. After 4 weeks of treatment, Bech-Rafaelsdn Mania Rating score was significantly lower in the observation group than in the control group [(7.36 ± 3.04) points vs. (10.23 ± 2.37) points, t = 5.38, P < 0.001]. The number of wrong responses and the number of perseverative errors in the Wisconsin Card Sorting Test in the observation group were (40.45 ± 3.61) counts and (9.56 ± 1.39) counts, respectively, which were significantly lower than those in the control group [(48.59 ± 4.51) counts, (12.08 ± 1.25) counts, t = 10.17, 9.56, both P < 0.001]. The number of perseverative errors in the Wisconsin Card Sorting Test was significantly higher in the observation group than in the control group [(33.85 ± 2.50) counts vs. (29.71 ± 2.14) counts, t = 8.90, P < 0.001]. There was no significant difference in total incidence of adverse reactions between observation and control groups (21.74% vs. 22.81%, χ2 = 0.01, P > 0.05). Conclusion:MECT combined with quetiapine treatment is highly effective on the manic episodes of bipolar disorder. The combined therapy is worthy of clinical application.
