[Effect of electroacupuncture on diaphragmatic function in patients with post-stroke tracheotomy].

Objective: To observe the effect of electroacupuncture (EA) on diaphragmatic function based on conventional treatment in patients with poststroke tracheotomy tube.

Methods: A total of 70 patients were randomized into an observation group (35 cases) and a control group (34 cases, 1 case dropped off). Internal medical basic treatment and breathing training were given in both groups. Besides, acupuncture was applied at Neiguan (PC 6), Shuigou (GV 26), Sanyinjiao (SP 6), Jiquan (HT 1), Chize (LU 5) and Weizhong (BL 40) in the control group, the needles were sustained for 30 min. On the basis of treatment in the control group, EA was applied at Tianding (LI 17), Fengchi (GB 20) and Jiaji (EXB 2, C-C ) in the observation group, with continuous wave, 10-20 Hz, 30 min each time. The treatment was given once a day, 6 times a week for 4 weeks in both groups. Before and after treatment, the diaphragmatic motility was measured by SonoSite ultrasound system (M-Turbo) in the two groups.

Results: Compared before treatment, the diaphragmatic motility after treatment was increased in both groups (<0.01), and the improvement in the observation group was superior to the control group (<0.01).

Conclusion: Electroacupuncture can promote the recovery of diaphragmatic function in patients with post-stroke tracheotomy tube.
