Swallowing & Dysphagia – GCCNurseJobs.com Clinical Guide

Types of Dysphagia

Oropharyngeal Dysphagia

Difficulty initiating swallow. Occurs in pharynx/upper oesophagus. Causes: stroke (most common), MND, Parkinson's, head/neck cancer, cerebral palsy. Presents with coughing, choking, wet voice, nasal regurgitation.

Oesophageal Dysphagia

Food sticking in chest/throat after swallow. Causes: strictures, achalasia, oesophageal cancer, GORD, eosinophilic oesophagitis. Managed by gastroenterology/surgery.

Common Causes by Prevalence

Stroke — most common cause; 50% of acute stroke patients have dysphagia
Motor Neurone Disease (MND) — progressive bulbar palsy; PEG early consideration
Parkinson's disease — silent aspiration common; difficulty with thin liquids
Head & neck cancer — post-surgery/radiotherapy structural changes
Dementia — late stage; coordination and cognitive dysfunction

IDDSI Framework — Texture Levels

Level	Name	Description
0	Thin	Normal water consistency
1	Slightly Thick	Nectar-like; flows off spoon
2	Mildly Thick	Flows like honey; slow pour
3	Liquidised	Smooth puree; no lumps
4	Pureed	Cohesive; holds shape on spoon
5	Minced & Moist	Small soft lumps ≤4mm
6	Soft & Bite-sized	Tender; requires minimal chewing
7	Regular	Normal food; no restriction

GUSS Screening Tool (Gugging Swallowing Screen)

5-step validated bedside screen for stroke patients. Score 0-20.

Part 1 — Indirect Swallowing Test (Max 5)

Vigilance: fully alert for ≥15 min
Voluntary cough/throat clearing
Swallow saliva: successful (1), drooling (–1), voice change (–1)

Part 2 — Direct Swallowing Test: Semi-solid → Liquid → Solid

Assess: swallow (1), coughing (–1), drooling (–1), voice change (–1)
Stop if any item scores ≤4

Score 20 = minimal risk | 15–19 = mild risk | 10–14 = moderate risk | 0–9 = severe risk (NPO + specialist)

Instrumental Assessment

FEES (Fibreoptic Endoscopic Evaluation)

Bedside-capable. Direct view of pharynx. Identifies aspiration, residue, laryngeal penetration. Gold standard in many settings.

Videofluoroscopy (MBS)

Gold standard overall. Real-time X-ray of swallow phases. Identifies penetration depth, timing, clearance. Requires radiation exposure and patient transfer.

Compensatory Strategies

Chin Tuck

Widens valleculae; reduces posterior bolus speed. Effective for delayed swallow trigger.

Head Turn

Turn toward weak side to close that pyriform sinus; directs bolus to stronger side.

Supraglottic Swallow

Breath hold before swallow, cough after. Closes glottis voluntarily.

Texture Modification

IDDSI framework. Thickened liquids for liquid aspiration. Soft diet for chewing problems.

Enteral Feeding Decisions

NGT (Nasogastric Tube)

Short-term feeding (<4 weeks). Verify position with pH aspirate (<5.5 = safe) or X-ray before each feed. High risk of misplacement. Reposition/reinsert if pH ≥6.

PEG (Percutaneous Endoscopic Gastrostomy)

For long-term use (>4 weeks). Surgically inserted. More comfortable; better for rehabilitation. Requires multidisciplinary decision-making. Not indicated if short-term recovery expected.

Oral Hygiene — Critical Prevention

Oral hygiene is the single most effective intervention to prevent aspiration pneumonia. Oral bacteria colonise the pharynx and are aspirated into lungs.

Brush teeth/dentures twice daily minimum
Chlorhexidine 0.12% rinse in high-risk patients
Keep mouth moist; use suction as needed
SALT referral for all dysphagic patients
Position patient upright 90° during meals and 30–60 min post-meal

Aspiration Pneumonia

Leading cause of mortality in dysphagic patients. Right lower lobe most commonly affected (gravity-dependent). Organisms: Streptococcus pneumoniae, anaerobes, gram-negatives.

Risk Factors

Reduced consciousness/sedation
Poor oral hygiene
Supine positioning
NGT feeding
Silent aspiration (common in Parkinson's)

Prevention

Upright 90° positioning
Meticulous oral hygiene
GUSS screening on admission
SALT referral within 24h
Appropriate texture modification

Malnutrition & Dehydration

Dysphagia severely impacts nutritional intake. Weight loss >5% over 1 month indicates high risk. Monitor BMI, MUST score, fluid intake. Thickened fluids reduce intake — supplement proactively. Involve dietitian early.

GCC-Specific Considerations

Arabic-Speaking SALT Shortage

Significant shortage of Arabic-speaking Speech and Language Therapists across GCC. Expatriate SALTs may not assess Arabic phonology accurately. Cultural liaison and trained interpreters are essential for accurate dysphagia assessment and patient education.

Ramadan: Texture-Modified Food at Iftar

Dysphagic Muslim patients observing Ramadan require culturally adapted texture-modified meals at Iftar (breaking fast). Fatigue after prolonged fasting may worsen swallowing function. Consult with patient and family regarding fasting decisions; involve religious advisor if clinically unsafe to fast.

Stroke Incidence & Dysphagia

GCC has high rates of hypertension, diabetes, and smoking — major stroke risk factors. Stroke is the leading cause of dysphagia in the region. Early dysphagia screening protocols in stroke units are being implemented across KSA, UAE, Qatar, Kuwait, Bahrain, and Oman.

GCC Clinical Practice Notes

PEG insertion is available in most tertiary centres across GCC. Consent must be obtained from patient/legal guardian (or male family representative per local custom). Halal considerations apply to feed components — ensure nutritional feeds are halal-certified for Muslim patients.

Rising incidence of nasopharyngeal and laryngeal cancers in GCC populations. Shisha (water pipe) smoking is prevalent and associated with head/neck malignancy. Post-radiotherapy dysphagia is a common and often severe late complication requiring long-term SALT input.

Key Exam Points

GUSS score ≤9 = severe dysphagia → NPO + SALT same day
NGT aspirate pH <5.5 = safe to feed; ≥6 = do NOT feed
NGT for short-term (<4 weeks); PEG for long-term (>4 weeks)
FEES/Videofluoroscopy = gold standard instrumental assessment
Oral hygiene = most critical aspiration pneumonia prevention measure
IDDSI Level 0 = thin (water); Level 7 = regular food
Chin tuck reduces posterior bolus velocity; useful for delayed trigger
Silent aspiration is most common in Parkinson's disease patients

Practice MCQs

1. A GUSS score of 9 in a post-stroke patient indicates:

2. Before administering an NGT feed, the nurse checks the aspirate. A pH of 6.5 indicates:

3. Which intervention most effectively prevents aspiration pneumonia in a dysphagic patient?

4. A patient with dysphagia has been nil by mouth for 5 weeks. The most appropriate long-term feeding route is:
