Swallowing assessment and management

Initial Screening - The Bedside Gulp Test

• Goal: Screen all stroke patients for dysphagia before any oral intake to prevent aspiration pneumonia. Maintain NPO status until the screen is passed.
• Method: The bedside swallow screen (BSS), often the 3-oz (90 mL) water swallow test.
• Observe for: Coughing, choking, wet/gurgly voice, or oxygen desaturation during or after swallowing.

⭐ A failed bedside screen mandates keeping the patient NPO (nothing by mouth) and ordering a formal swallowing evaluation to prevent aspiration.

Formal Evaluation - Scopes & Swallows

Following a failed bedside screen, definitive instrumental tests are used to visualize swallow anatomy and physiology, guiding diet modification and therapy.

Management - Safe-Swallow Strategies

• Diet Modification: Crucial for preventing aspiration pneumonia.

  • Altering food textures (e.g., pureed, minced) and liquid consistencies.
  • National Dysphagia Diet (NDD): Standardizes textures. Liquids are often thickened (e.g., nectar-thick, honey-thick) to slow flow, allowing more time for airway closure.

• Compensatory Strategies: Immediate techniques to improve swallowing safety.

  • Postural adjustments (e.g., head turn, chin-tuck).
  • Altering bolus size and placement in the oral cavity.

⭐ The 'chin-tuck' maneuver is a simple but highly effective compensatory strategy that physically narrows the airway entrance, helping to protect against aspiration.

• Rehabilitation Exercises: Aim to restore long-term swallow function.
  • Strengthening exercises for tongue, lips, and pharyngeal muscles (e.g., Masako maneuver, Shaker exercise).

Complications & Nutrition - The Danger Zone

• Aspiration Pneumonia: The most critical complication of dysphagia. Silent aspiration (no overt cough/choke) is common. Presents with fever, cough, and ↓O₂ saturation.
• Malnutrition & Dehydration: Result from inadequate oral intake, impairing recovery and increasing infection risk.
• Feeding Tube Management:
  • Short-term (< 4-6 weeks): A nasogastric (NG) tube is used for initial nutritional support.
  • Long-term (> 4-6 weeks): A percutaneous endoscopic gastrostomy (PEG) tube is indicated.

⭐ For long-term (> 4-6 weeks) dysphagia, a PEG tube is preferred over an NG tube to reduce the risk of sinusitis, esophagitis, and tube displacement.

• All stroke patients require a swallowing screen before any oral intake to prevent aspiration.
• Keep patients NPO (nothing by mouth) until this initial bedside assessment is passed.
• A failed bedside screen necessitates a videofluoroscopic swallowing study (VFSS), the gold standard for diagnosis.
• Aspiration pneumonia is a major complication of post-stroke dysphagia.
• Management includes dietary modifications (e.g., thickened liquids, pureed diet) and speech therapy.
• For severe dysphagia, consider enteral feeding via NG or PEG tube.
