Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

It was well known that long term intubation caused a various kind of abnormal presentations of dysphagia such as the increased aspiration risk, the decreased gag reflex, mucosal pathology, the airway stenosis and so on. It was thought that the freezing and impaired proprioception to be developed as a result of dis-use around the pharynx and the larynx while intubation was one of the reason.

Preemptive swallowing manual stimulation applied on the oral cavity to avoid the vicious cycle of dis-use was reported to improve dysphagia after extubation.

Neuromuscular electrical stimulation have been utilized for a wide variety of dysphagia of multiple causes of neuro-muscular disorder.

Supposing that preemptive transcutaneous neuromuscular electrical stimulation to be delivered to the muscles of being involved in swallowing could decrease the degree of dis-use during intubation so that it could reduce the occurence and severity of dysphagia developed after extubation, the investigators plan to perform randomized prospective double blind placebo controlled clinical interventional study.

Transcutaneous neuro-muscular electrical stimulation

Neuro-muscular electrical stimulation with two pairs of surface electrodes was applied to submental area. One paired electrodes to be placed horizontally was attached on the anterior half of area between mandible and hyoid bone. The other was affixed to posterior half of the same area far laterally. Bipolar electrical stimulation with pulse rate of 80-Hz, duration of 700 µs and intensity to evoke visible muscle contraction was performed for 60 minutes a day until one day before extubation.
