Effects of Buqi Huayu decoction combined with low-frequency pulse electrical stimulation in treatment of patients with incomplete uterine involution and qi deficiency and blood stasis syndrome
Objective:To observe effects of Buqi Huayu decoction combined with low-frequency pulse electrical stimulation in treatment of patients with incomplete uterine involution and qi deficiency and blood stasis syndrome.Methods:A prospective study was conducted on 86 patients with incomplete uterine involution and qi deficiency and blood stasis syndrome admitted to this hospital from March 2021 to March 2023.According to the random number table method,they were divided into control group and observation group,43 cases in each group.The control group was treated with low-frequency pulse electrical stimulation,while the observation group was treated with Buqi Huayu decoction on the basis of that of the control group.Both groups were treated for 7 d.The clinical efficacy,the TCM syndrome scores,the symptom-related indicators(lochia end time,waist and abdomen bulge disappearance time,uterine tenderness disappearance time)levels,the uterine artery blood flow parameters[pulsatility index(PI),resistance index(RI),peak systolic velocity(PSV)]levels,and incidence of adverse reactions were compared between the two groups before and after the treatment.Results:The total effective rate of the observation group was 90.70%(39/43),which was higher than 69.77%(30/43)of the control group,and the difference was statistically significant(P<0.05).After the treatment,the scores of TCM syndromes such as main symptoms and secondary symptoms in the observation group were lower than those in the control group,and the differences were statistically significant(P<0.05).The lochia end time,the waist and abdomen bulge disappearance time,the uterine tenderness disappearance time in the observation group were shorter than those in the control group,and the differences were statistically significant(P<0.05).After the treatment,the RI and PI levels in the observation group were lower than those in the control group,the PSV level was higher than that in the control group,and the differences were statistically significant(P<0.05).However,there was no significant difference in the incidence of adverse reactions between the two groups(P>0.05).Conclusions:Buqi Huayu decoction combined with low-frequency pulse electrical stimulation can improve the total effective rate of treatment,reduce the TCM syndrome scores,improve the levels of symptoms related indicators and uterine artery blood flow parameters in the treatment of the patients with incomplete uterine involution and qi deficiency and blood stasis syndrome.Moreover,it is superior to single low-frequency pulse electrical stimulation treatment.
