Unlabelled:
Aspiration in dysphagic stroke patients is common and causes significant morbidity and mortality. Bedside clinical assessment of aspiration risk is often unreliable, particularly in patients with silent aspiration. Twenty-five dysphagic stroke patients clinically assessed to have borderline risk of aspiration were studied using a Modified Barium Swallow (MBS) examination. MBS revealed definite aspiration of liquids in 6 patients (24%) and semisolids in 4 patients (16%). Combined clinical and MBS assessment revealed an additional 12 patients (48%) had problems swallowing liquids and 5 patients (20%) semisolids due to reasons other than aspiration. In total, oral feeding of liquids were contraindicated in 18 patients (72%) and semisolids in 9 patients (36%).
In Conclusion:
(1) In dysphagic stroke patients assessed clinically to have borderline risk of aspiration, MBS can distinguish those who aspirate from those who do not. MBS can also identify patients with other swallowing problems which expose them to potential aspiration. (2) Aspiration risk with food of various consistencies can be clearly defined, thus guiding the choice of food consistency and safe feeding methods.
Insights
Modified Barium Swallow (MBS) is crucial for assessing aspiration risk in stroke patients with dysphagia. This study found MBS identified significant swallowing issues, including aspiration, in many patients initially deemed at borderline risk, guiding safe feeding strategies.
Area of Science:
- Neurology
- Gastroenterology
- Speech-Language Pathology
Background:
- Aspiration is a common complication in stroke patients with dysphagia, leading to increased morbidity and mortality.
- Clinical bedside assessment for aspiration risk is often unreliable, especially in cases of silent aspiration.
- Dysphagia management requires accurate identification of swallowing impairments.
Purpose of the Study:
- To evaluate the utility of Modified Barium Swallow (MBS) in identifying aspiration and other swallowing problems in dysphagic stroke patients.
- To compare clinical assessment with MBS findings in determining aspiration risk.
- To guide safe oral feeding strategies based on identified swallowing difficulties.
Main Methods:
- Twenty-five dysphagic stroke patients with borderline clinical aspiration risk were assessed using Modified Barium Swallow (MBS).
- MBS examinations evaluated aspiration of liquids and semisolids.
- Clinical assessments were combined with MBS findings to identify all swallowing-related issues.
Main Results:
- MBS detected definite aspiration of liquids in 24% and semisolids in 16% of patients.
- An additional 48% of patients had liquid swallowing problems and 20% had semisolids swallowing problems not initially identified by clinical assessment.
- Oral feeding of liquids was contraindicated in 72% and semisolids in 36% of patients.
Conclusions:
- Modified Barium Swallow (MBS) effectively differentiates between aspirating and non-aspirating dysphagic stroke patients.
- MBS identifies other swallowing issues beyond aspiration, crucial for patient safety.
- MBS findings clearly define aspiration risk across different food consistencies, informing feeding recommendations.
