Insights
Videofluoroscopic swallowing study (VFSS) effectively diagnoses pediatric dysphagia, leading to improved nutrition and respiratory health in children with neurological disabilities. Early diagnosis and tailored treatment significantly benefit these vulnerable patients.
Area of Science:
- Pediatric Gastroenterology
- Neurology
- Speech-Language Pathology
Background:
- Dysphagia is prevalent in children with neurological disabilities, causing significant respiratory and nutritional issues.
- The videofluoroscopic swallowing study (VFSS) is crucial for evaluating swallowing function in real-time.
Purpose of the Study:
- To analyze the outcomes of VFSS implementation over one year.
- To assess clinical improvement and individualized treatment efficacy post-VFSS diagnosis.
Main Methods:
- Retrospective analysis of 61 VFSS procedures.
- Evaluation of patient demographics, neurological conditions, dysphagia severity, aspirations, and treatment outcomes.
- Statistical analysis using SPSS v21.
Main Results:
- Over 70% of patients exhibited dysphagia, with 58% being moderate-severe.
- Aspirations/penetrations occurred in 59%, including 50% silent aspirations.
- Nutritional and respiratory improvements were observed following VFSS-guided treatment adjustments.
Conclusions:
- VFSS implementation led to a high diagnosis rate and significant patient benefit.
- VFSS is a vital diagnostic tool for pediatric dysphagia, recommended for inclusion in all pediatric centers.
Introduction:
Dysphagia is very common in children with neurological disabilities. These patients usually suffer from respiratory and nutritional problems. The videofluoroscopic swallowing study (VFSS) is the most recommended test to evaluate dysphagia, as it shows the real situation during swallowing.
Objectives:
To analyse the results obtained in our centre after one year of the implementation of VFSS, the clinical improvement after confirmation, and the prescription of an individualised treatment for the patients affected.
Material And Methods:
VFSS performed in the previous were collected. The following variables were analysed: age, pathology, degree of neurological damage, oral and pharyngeal and/or oesophageal dysphagia and its severity, aspirations, prescribed treatment, and nutritional and respiratory improvement after diagnosis. A statistical analysis was performed using SPSS v21.
Results:
A total of 61 VFSS were performed. Dysphagia was detected in more than 70%, being moderate-severe in 58%. Aspirations and/or penetrations were recorded in 59%, of which 50% were silent. Adapted diet was prescribed to 56%, and gastrostomy was performed on 13 (21%) patients. A statistical association was found between neurological disease and severity of dysphagia. The degree of motor impairment is related to the presence of aspirations. After VFSS evaluation and treatment adjustment, nutritional improvement was found in Z-score of weight (+0.3SD) and BMI (+0.4SD). There was respiratory improvement in 71% of patients with dysphagia being controlled in the Chest Diseases Department.
Conclusions:
After implementation of VFSS, a high percentage of patients were diagnosed and benefited from a correct diagnosis and treatment. VFSS is a fundamental diagnostic test that should be included in paediatric centres as a diagnostic method for children with suspected dysphagia.
