About
Post-extubation dysphagia (PED) is characterized by a range of clinical manifestations, including absence of visible swallowing effort, coughing or choking following liquid intake, and post-swallowing dysarthria. These impairments may lead to severe complications such as aspiration pneumonia, electrolyte disturbances, and malnutrition. Currently, the majority of hospitals both domestically and internationally have not implemented routine screening for PED or standardized swallowing rehabilitation programs, and research on the recovery of swallowing function in PED remains limited. This study aims to investigate the therapeutic efficacy of bilateral high-frequency repetitive transcranial magnetic stimulation (rTMS) combined with conventional swallowing training in patients with PED, and to evaluate the influence of oral feeding on functional recovery and the incidence of pneumonia.
The study design is a single-center, randomized, single-blind, parallel-controlled trial. Participants with PED will be randomly assigned to either a swallowing training group or a bilateral high-frequency repetitive transcranial magnetic stimulation plus swallowing training group.The primary outcome measure is the Functional Oral Intake Scale (FOIS) score，which assesses oral feeding ability.Secondary outcomes include the Wakada Drinking Water Test(WST),degree of swallowing difficulty(GUSS),the incidence rate of pneumonia and length of stay.These secondary outcomes will provide a comprehensive evaluation of swallowing ability and hospitalization effects.
Random grouping was conducted within 4 hours after extubation, and the treatment began within 2 hours and lasted for 3 consecutive days.Each rTMS session will target key brain regions.Swallowing training includes facial function training, sensory stimulation training, and airway protection techniques.The observation group received bilateral high-frequency transcranial magnetic stimulation in addition to the swallowing training.The data will be collected before and after the treatment.The primary outcome, FOIS score, will be used to assess the overall improvement in oral feeding ability.WST and GUSS data will be collected to evaluate a comprehensive evaluation of swallowing ability.The incidence rate of pneumonia and length of stay will be used to assess change in side effects.
Statistical analyses will be performed using SPSS 22.0. Data will be presented as mean ± standard deviation. Between-group differences will be compared using independent samples t-tests.
The study timeline spans from September 2025 to December 2026, including participant recruitment, intervention implementation, data collection, and analysis, as well as manuscript drafting. This study aims to provide new insights into the treatment methods for PED and explore a new rehabilitation approach that can be used in the ICU, with the expectation of improving swallowing disorders and reducing complications.
