A comprehensive clinical reference for GCC nursing professionals
GCC / DHA / DOH / SCFHS Aligned · 2026| Class | Visible | Significance |
|---|---|---|
| I | Soft palate, uvula, tonsils, pillars | Easy |
| II | Soft palate, upper uvula | Moderate |
| III | Soft palate base only | Difficult |
| IV | Hard palate only | Very difficult |
Neck flexed on body + head extended at atlantoaxial joint. Aligns oral, pharyngeal, and laryngeal axes. Best for direct laryngoscopy (DL).
Elevate upper body and head until external auditory meatus is horizontal with the sternal notch. Improves laryngoscopy grade and reduces desaturation time.
High-pitched breath sound. Indicates partial obstruction — airway is present but narrowed. Inspiratory stridor = supraglottic. Expiratory = subglottic/tracheal. Biphasic = severe.
Complete obstruction — no air movement, no breath sounds. Silent chest in asthma is ominous. No stridor = no airway. Immediate action required.
| Parameter | Detail |
|---|---|
| Sizing | Tip of nostril → earlobe (external). Adult: 6–7 mm ID |
| Insertion | Lubricate well. Right nostril preferred (valve anatomy). Bevel toward septum. Gentle rotation if resistance |
| Contraindications | Base of skull fracture (Battle's sign, raccoon eyes, CSF rhinorrhoea), coagulopathy, nasal obstruction |
| Advantages | Tolerated in semi-conscious / intact gag reflex |
| Complications | Epistaxis, malposition, laryngospasm |
| Parameter | Detail |
|---|---|
| Sizing | Incisors → angle of jaw (corner of mouth). Colour coded: adult 80–100 mm |
| Insertion (Adult) | Insert concave-down, rotate 180° as it passes hard palate |
| Insertion (Child) | Insert correct orientation (concave up) with tongue depressor — do NOT rotate in children |
| Contraindications | Conscious patient with intact gag reflex (induces vomiting/laryngospasm) |
| Complications | Vomiting, laryngospasm, dental trauma if wrongly sized |
| Device | Size | Features & Notes |
|---|---|---|
| Classic LMA | 3 (small female), 4 (large female/small male), 5 (large male) | Inflatable cuff. First-line SGA. Not definitive airway — aspiration risk. |
| i-gel | 4 (50–90 kg), 5 (>90 kg) | No inflatable cuff — thermoplastic gel forms seal. Faster insertion. Gastric port channel. |
| LMA ProSeal | 3 / 4 / 5 | Dual lumen: airway + gastric port for NG tube. Better seal — tolerates higher ventilation pressures. Preferred when regurgitation risk. |
| LMA Supreme | 3 / 4 / 5 | Reinforced, single-use, curved. Gastric port. Easier blind insertion. |
| Patient | Rate | Volume |
|---|---|---|
| Adult | 10–12 breaths/min | 500–600 mL (6–8 mL/kg) |
| Paediatric | 12–20 breaths/min | Visible chest rise |
| Arrest (with airway) | 10 breaths/min | Avoid hyperventilation |

| Drug | Class | Dose | Onset | Notes |
|---|---|---|---|---|
| Suxamethonium (Succinylcholine) | Depolarising NMBA | 1.5 mg/kg IV | 60–90 sec | Duration ~10 min. Contraindicated: hyperkalaemia, burns >48h, crush injury, malignant hyperthermia risk, denervation injury |
| Rocuronium | Non-depolarising NMBA | 1.2 mg/kg for RSI (high dose) | 60–90 sec | Duration 60 min. Reversible with Sugammadex 16 mg/kg. Preferred when sux contraindicated |
| Ketamine | Induction agent | 1–2 mg/kg IV | 60 sec | Maintains airway reflexes, bronchodilator, haemodynamic stability — preferred in haemodynamic instability/asthma/trauma |
| Propofol | Induction agent | 1.5–2.5 mg/kg IV | 30–60 sec | Reduce dose in elderly/hypovolaemia. Causes hypotension. Good antiemetic properties |
| Thiopental | Induction agent | 3–5 mg/kg IV | 30 sec | Reduces ICP. Avoid in porphyria. Causes significant hypotension |
ETT tip should sit 3–5 cm above the carina on CXR. Carina typically at T4–T5. Order CXR immediately after intubation and check before starting sustained ventilation.
| Feature | Surgical Tracheostomy | Percutaneous (PDT) |
|---|---|---|
| Setting | Operating theatre | ICU bedside |
| Operator | Surgeon (ENT/general) | Intensivist/trained physician |
| Technique | Open dissection, tracheal window | Seldinger technique (Ciaglia Blue Rhino most common) |
| Timing | Any time, emergency or elective | Elective only; not first 72h post-intubation (some centres 7 days) |
| Complications | Higher bleeding, infection, longer scar | Paratracheal placement risk, lower infection |
| Nurse role | Post-op wound care, monitoring | Pre-procedure prep, bronchoscopy assist, monitoring |
| Type | Indications | Key Notes |
|---|---|---|
| Cuffed | Ventilated patients, aspiration risk, early post-op | Cuff seals airway for positive pressure ventilation. Check pressure every shift |
| Uncuffed | Long-term tracheostomy, weaned from ventilator, no aspiration risk | Allows more airflow around tube for phonation. No cuff pressure monitoring needed |
| Fenestrated | Weaning, speaking valve use, decannulation pathway | Hole(s) in outer/inner cannula allow airflow through larynx. MUST use non-fenestrated inner cannula when ventilating — fenestrated causes leak |
| Adjustable Flange (Tight-to-shaft / Adjustable Neck) | Obese patients, excessive SC tissue, unusual anatomy | Flange repositionable to accommodate any neck depth. Risk of displacement if not secured |
Frequency: Every 4–8 hours or as needed (blocked secretions, increased work of breathing)
Equipment: Sterile gloves, sterile water/saline, small brush, sterile bowl × 2, apron, eye protection
Catheter size: Internal diameter of tube (mm) × 2 = suction catheter size (French). Example: 8 mm tube → 16 Fr catheter. Never exceed 50% of tube internal diameter.
Depth: Insert to tip of tracheostomy tube ONLY — not beyond (avoid deep endobronchial suctioning routinely). Some centres allow 1 cm past tip.
Minimum humidification standard for breathing tracheostomy patients. Captures exhaled heat and moisture, releases on inspiration. Change every 24h or sooner if visibly contaminated.
For ventilated patients or those with thick/tenacious secretions. Target: 37°C, 44 mg H₂O/L absolute humidity at airway opening. Circuit condensate is biohazardous — handle carefully.
Identical replacement tube with intact cuff, tested and ready
Rescue tube if reinsertion of same size fails
To cut securing tapes urgently if tube needs emergency removal
Roscoe-style dilators to maintain/open stoma during reintubation
For both tracheostomy and oral ventilation (if stoma covered/oral intubation needed)
Yankauer + suction catheter + portable capnography to confirm tube position
| Emergency | Priority Actions | Caution |
|---|---|---|
| Tube Displacement | 1. Call for help. 2. Attempt reinsertion of same tube with obturator. 3. If fails: insert smaller tube through stoma. 4. If stoma patent: cover stoma + oral airway. 5. Oral intubation through mouth as rescue route. | Do NOT force tube blindly. Use dilators to maintain stoma patency. |
| Tube Occlusion | 1. Remove inner cannula — if immediate improvement: clean/replace inner cannula. 2. Pass suction catheter to clear secretions. 3. Deflate cuff — trial of oral breathing. 4. Change tube if above fails. | Always remove inner cannula first — quickest action. Diagnose before changing tube. |
| Significant Bleeding | 1. Nurse senior help + emergency call. 2. Over-inflate cuff (above 30 cmH₂O as temporising measure only). 3. Lie patient flat. 4. Suction blood from airway. 5. Urgent surgical review — suspicion of arterio-tracheal fistula. | Innominate artery/arterio-tracheal fistula = life-threatening. Do NOT deflate cuff until surgical team present. |
| Inadvertent Decannulation (First 5–7 Days) | 1. Call for help immediately. 2. Do NOT attempt to reinsert — stoma may close. 3. Oral airway/BVM via mouth. 4. Anaesthetics/ENT for oral intubation or stoma maintenance. 5. Treat as lost airway. | Stoma not yet epithelialised — closes within minutes. High risk of paratracheal placement if forced reinsertion attempted. |
| Subcutaneous Emphysema | 1. Stop ventilating via tracheostomy. 2. Ensure tube in correct position (capnography). 3. Consider tube displacement into SC tissue. 4. CXR — check for pneumothorax. 5. Urgent surgical review. | Crepitus on palpation of neck = SC emphysema. May indicate false passage creation or pneumothorax. |
