Effect of Modified Air-pulse Stimulation on Tracheotomised Patients With Dysphagia After Stroke

March 1, 2024 updated by: The Second Affiliated Hospital of Dalian Medical University
To evaluate the efficacy of flexible endoscopy-mediated modified air-pulse stimulation in restoring of swallowing function in this group of patients.Forty-two subacute stroke patients with tracheotomy and dysphagia need to be recruited and divided into a control group of 21 cases and a trial group of 21 cases. On the basis of receiving personalized swallowing rehabilitation training, the control group received traditional air-pulse stimulation therapy, while the trial group received modified air-pulse stimulation therapy mediated by flexible endoscopy. Murray secretion scale (MSS), penetration-aspiration scale (PAS) and spontaneous swallowing frequency were used to assess dysphagia. Moreover, clinical pulmonary infection score (CPIS) was used for evaluating the degree of pneumonia, hemoglobin(Hb) and serum prealbumin (PAB) were used to assess the nutritional status of patients.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • patients who met the diagnostic criteria for stroke formulated in the 4th National Academic Conference on Cerebrovascular disease;
  • patients with relatively stable vital signs, with a NIHSS score of 21 points;
  • patients with tracheotomy accompanied by dysphagia;
  • no previous history of dysphagia;
  • age ≥ 30 years and ≤80 years;
  • informed consent signed by the patient and his family.

Exclusion Criteria:

  • patients with medullary haemorrhage/infarction;
  • patients that experienced cerebral hernia and recurrent stroke;
  • patients with unstable arrhythmia, fever, infection, severe restlessness and inability to cooperate with treatment;
  • patients with gastro-oesophageal reflux, bilateral paralysis of the vocal cord, laryngopharyngeal stenosis/haemorrhage/tumour;
  • patients in which there was an inability to accurately locate epiglottis and arytenoid cartilage due to throat disease;
  • patients with a history of epilepsy or risk of seizures.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Sham Comparator: control group
Based on receiving personalized swallowing rehabilitation training, the control group received traditional air-pulse stimulation therapy.
Behavioral: Conventional air-pulse stimulation
The terminal airway of the air pulse was placed in the oral cavity, specifically in the patient's palatoglossal arch, pharyngeal posterior wall, tongue base, and other areas. The airbag was quickly squeezed to generate airflow and stimulate the mucosa.(5 min once a day for 2 weeks)
Experimental: trial group
The trial group received modified air-pulse stimulation therapy mediated by flexible endoscopy.
Behavioral: Modified Air-pulse Stimulation
Connected the oxygen humidification bottle to a fibreoptic endoscope, then inserted the terminal into the nasal cavity and the pulse sensation stimulation generated by oxygen was transmitted through the internal port of the fibreoptic endoscope to the anterior wall of the pyriform recess or to the folds of the arytenoepiglottis. (5 min once a day for 2 weeks)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
