Guipi Decoction Combined with Acupuncture in the Treatment of Cervical Vertigo from Qi–Blood Deficiency: Efficacy and Effects on Hemodynamics

Objective This study aimed to observe Guipi decoction combined with acupuncture's clinical efficacy in treating cervical vertigo of qi–blood deficiency and its influences on hemodynamics. Methods A total of 120 patients with qi–blood deficiency cervical vertigo treated at our hospital from January 2021 to January 2025 were selected and randomly divided into a control group ( n = 60) and an observation group ( n = 60). The control group received conventional Western medication, while the observation group received additional Guipi decoction and acupuncture, with a 4-week treatment course for both groups. Between the two groups, the Evaluation Scale for Cervical Vertigo (ESCV), traditional Chinese medicine (TCM) clinical syndrome score, hemodynamic indicators [mean blood flow velocity (Vm) of basilar artery, left and right artery, resistance index (RI), pulsatility index (PI)], quality of life [Dizziness Handicap Inventory (DHI)], and incidence of adverse reactions were compared. Results The effective rate in the control group was 71.67% (43/60), which was lower than that of the observation group at 86.67% (52/60) after 4 weeks of treatment, with a statistically significant difference ( P < 0.05). Compared with that of the control group, the ESCV score in the observation group was higher, and the TCM clinical syndrome score was lower after 4 weeks of treatment, with statistically significant differences ( P < 0.05). After 4 weeks of treatment, the Vm of the basilar artery and left and right vertebral arteries in the observation group increased, while the RI and PI decreased, with statistically significant differences ( P < 0.05). During the follow-up of 3 months, compared with the control group, the multidimensional and total DHI scores in the observation group were lower, and the difference was statistically significant ( P < 0.05). In the treatment process, between the two groups, there was no statistically significant difference in the incidence of adverse reactions ( P > 0.05). Conclusion Guipi decoction combined with acupuncture in the treatment of cervical vertigo of qi–blood deficiency can effectively improve TCM clinical symptoms, positively regulate hemodynamics, and suggest potential therapeutic benefits.
