[Effect of auricular electroacupuncture on tracheal extubation success rate in patients with post-stroke tracheotomy: a randomized controlled trial].

Researchers in China studied whether auricular electroacupuncture (ear acupuncture with electrical stimulation) could help stroke patients who needed breathing tubes after their stroke. The study included 84 patients who had undergone tracheotomy, a surgical procedure that creates an opening in the neck for a breathing tube. All patients received standard care, but the treatment group also received electroacupuncture on two specific ear points called Fei (lung) and Yanhou (pharynx larynx) for 20 minutes daily, six days per week for four weeks.

The results were impressive. Nearly 90% of patients receiving ear electroacupuncture successfully had their breathing tubes removed, compared to only 60% in the control group. These patients also had their tubes removed faster than those receiving standard care alone. The treatment group showed significant improvements in cough strength, cough reflex responses, swallowing speed, and reduced risk of food or liquid entering the airway. No adverse reactions were reported in either group.

Researchers believe the ear acupuncture works by stimulating the vagus nerve through the ear, which helps restore normal cough and swallowing reflexes that are often impaired after stroke. For stroke patients requiring breathing support, this therapy may offer a safe way to speed recovery and reduce dependence on mechanical breathing assistance. If you're considering acupuncture for stroke recovery, seek a licensed acupuncturist with experience treating neurological conditions.

This randomized controlled trial examined auricular electroacupuncture for post-stroke tracheotomy patients (n=75 completed; 38 treatment, 37 control). The intervention group received bilateral electroacupuncture at CO14 (Fei/Lung) and TG3 (Yanhou/Pharynx-Larynx) using intermittent wave, 5 Hz frequency, 1 mA current, 20-minute retention, delivered daily for 4 weeks (6 days on, 1 day off). Controls received swallowing electrical stimulation only. The treatment group achieved significantly higher decannulation success (89.5% vs 59.5%, P<0.01) with shorter time to extubation (P<0.001). Secondary outcomes showed superior improvements in involuntary cough peak flow, tracheal cough reflex scores, pharyngeal transit time, and penetration-aspiration scores versus controls (all P<0.01-0.05). No adverse events occurred. The proposed mechanism involves auricular vagal nerve activation enhancing protective airway reflexes. This suggests auricular electroacupuncture may be an effective adjunct therapy for facilitating successful decannulation in stroke patients with tracheostomy.
