[Effects of acupuncture at back-shu points on respiratory function and extubation success rate in patients with post-stroke tracheotomy].

OBJECTIVE: To observe the effect of acupuncture at back-shu points on patients with post-stroke tracheotomy on the basis of extracorporeal diaphragmatic pacing (EDP) combined with conventional acupuncture. METHODS: A total of 64 patients with post-stroke tracheotomy were randomly divided into an experiment group (32 cases, 2 cases dropped out) and a control group (32 cases, 2 cases dropped out). The control group received EDP combined with conventional acupuncture, acupuncture was applied at Baihui (GV20), Zhongwan (CV12) and bilateral Fengchi (GB20), Quchi (LI11), Hegu (LI4), Neiguan (PC6), Xuehai (SP10) , Yinlingquan (SP9), Sanyinjiao (SP6), Zusanli (ST36), 30 min each time. The experiment group was treated with acupuncture at bilateral Feishu (BL13), Pishu (BL20), Shenshu (BL23) on the basis of the treatment in the control group, 30 min each time. Acupuncture in both groups was given once a day, 5 days a week for 4 weeks. Before and after treatment, the pulmonary function (forced vital capacity [FVC], first second forced expiratory volume [FEV1], peak expiratory flow [PEF], maximal inspiratory pressure [MIP], maximal expiratory pressure [MEP]), diaphragmatic thickening fraction (DTF), diaphragm excursion (DE), postural assessment scale for stroke patients (PASS) score and Berg balance scale (BBS) score were observed in the two groups. The extubation success rate was recorded in the two groups. RESULTS: After treatment, the FVC, FEV1, PEF, MIP and MEP in the two groups were increased compared with those before treatment (P<0.001), and above indexes in the experiment group were higher than those in the control group (P<0.001, P<0.01). After treatment, the DTF and DE in the two groups were increased compared with those before treatment (P<0.001), the DE in the experiment group was higher than that in the control group (P<0.001). After treatment, the PASS and BBS scores in the two groups were increased compared with those before treatment (P<0.001), and the BBS score in the experiment group was higher than that in the control group (P<0.001). The extubation success rate of the experiment group was 73.3% (22/30), which was higher than 46.7% (14/30) in the control group (P<0.05). CONCLUSION: On the basis of EDP combined with conventional acupuncture, acupuncture at back-shu points can improve the pulmonary function, respiratory muscle strength, trunk control and balance abilities in patients with post-stroke tracheotomy, and increase the extubation success rate.
