Cooling-flavored supplements to help swallowing after acute stroke

Evaluation of the Perception of Freshness and Swallowing Safety in Stroke Patients With Dysphagia Receiving a Specially Designed Thickened Oral Nutritional Supplement: the Cooling Sensation Safe Deglution Study

NA · Fundación Pública Andaluza para la Investigación de Málaga en Biomedicina y Salud · NCT06936501

This study will test whether refreshing, cooling-flavored high-protein oral supplements help hospitalized adults with post-stroke dysphagia swallow and tolerate nutrition better than traditional flavors.

What this trial studies

Hospitalized adults with acute stroke and dysphagia confirmed by the V-VST who are at risk of malnutrition receive thickened, high-calorie, high-protein oral nutritional supplements in either traditional (vanilla or strawberry) or refreshing/cooling (mango-peppermint or lemon-mint) flavors by choice. Clinical swallow assessments, intake measures, tolerance observations and patient questionnaires are used to collect data during the hospital stay. The trial compares swallow safety, nutritional intake, and patient acceptance between the two flavor approaches using routine clinical tools and consented participation. Results aim to inform whether a sensory-modified supplement can improve intake and reduce complications in the acute post-stroke period.

Who should consider this trial

Good fit: Adults over 18 hospitalized for acute stroke with V-VST–confirmed dysphagia and judged to be malnourished or at risk who can give informed consent and complete questionnaires are ideal candidates.

Not a fit: Patients with moderate-to-severe cognitive impairment, advanced dementia, severe psychiatric illness, galactosemia, intolerance to supplement ingredients, or other barriers to understanding or cooperating are unlikely to benefit or are excluded.

Why it matters

Potential benefit: If successful, cooling or refreshing flavors could increase safe oral intake, reduce malnutrition and lower aspiration-related respiratory complications after stroke.

How similar studies have performed: Some prior studies show that sensory stimuli such as cold or sour boluses can speed the swallow reflex and improve safety in people with dysphagia, but using cooling-flavored oral nutritional supplements is a relatively novel approach with limited direct evidence.

* Malnutrition or risk of malnutrition, requiring a thickened, high-calorie, high-protein ONS, as determined by medical assessment in routine clinical practice.
* Voluntary written informed consent to participate in the study.

Exclusion Criteria:

* Moderate to severe cognitive impairment that interferes with the correct interpretation of the study or its requirements.
* Diagnosis of advanced dementia, severe psychiatric illness, or any other central nervous system condition that impairs the patient's comprehension of the study.
* Sociocultural, linguistic, intellectual, or other factors that hinder the patient's proper understanding of the study.
* Diagnosis of galactosemia.
* Intolerance or refusal (for any reason) of oral nutritional supplements.
* Requirement for parenteral nutrition or contraindication to oral intake.
* Severe active renal, hepatic, or gastrointestinal diseases that contraindicate the use of ONS
