Clinical study of electroacupuncture and Shenmai injection combined with conventional western therapy as treatments for the sudden deafness / 国际中医中药杂志

ABSTRACT

Objective To observe the clinical effect of electroacupuncture and Shenmai injection combined with conventional western therapy as treatments for the sudden deafness.Methods A total of 186 patients with sudden deafness were randomly divided into two groups. Each group included 93 patients. The control group was treated with the pipe-expanding and anti-inflammatory, but the treatment group was treated with electroacupuncture and Shenmai injection based on the control group. Both groups were treated for 11 days.Before and after treatments, the regional cerebral blood flow (rCBF) was detected. The MADSEN was used to detect ocular vestibular evoked myogenic potential (oVEMP), including N1-Pl amplitude, N 1-Pl incubation period, N1-Pl wave duration and extraction rate of oVEMP.Results The recovery rate of control group was 63.4% (59/93) and total effective rate was 90.3% (84/93), which was 88.6% (75/93) and 97.8% (91/93) in combined treatment group, and there was significant difference between the 2 groups (χ2=5.923,P<0.05). After 11 days of treatment, the Tinnitus (17.2%vs. 30.1%,χ2=7.152), vertigo and survival rate (15.1%vs. 21.5%, χ2=6.023) in combined treatment group showed significantly lower than those in the control group (P<0.05). The threshold (39.59 ± 5.36 dBHLvs. 45.85 ± 5.08 dBHL,t=2.903) in combined treatment group showed significantly lower than those in the control group (P=0.034). The N1 amplitude (10.62 ± 0.84μVvs. 7.14 ± 0.59μV;t=3.259,P=0.017), P1 amplitude (11.79 ± 0.91μVvs. 9.90 ± 0.82μV;t=2.871,P=0.037), extraction rate of oVEMP (95.7%vs. 81.7%;χ2=7.963,P=0.012) in combined treatment group showed significantly higher than those in the control group. The N1 incubation period (7.86 ± 0.82 msvs. 9.78 ± 1.24 ms;t=3.729,P=0.009) and Pl incubation period (6.57 ± 0.77 msvs. 9.39 ± 1.15 ms;t=3.064,P=0.025) in combined treatment group showed significantly lower than those in the control group.Conclusions The Electroacupuncture and Shenmai injection combined with conventional western therapy could improve blood circulation produce a synergistic therapeutic effect on damaged tissue, improve cochlear hair cells and vestibular nerve regeneration, and repaire the functions.
