Percutaneous Tracheostomy Kit

(Percutaneous Dilatational Tracheostomy - PDT)

For Anesthesia PG Assignment | 10 Marks

1. Introduction

Percutaneous Dilatational Tracheostomy (PDT) is the most common bedside airway procedure performed in critically ill patients in the ICU. First described by Ciaglia et al. in 1985 (Chest 87:715-719), it has largely replaced open surgical tracheostomy for elective airway access in mechanically ventilated patients. The technique relies on the Seldinger (guidewire-based) principle - using progressive dilatation over a guidewire to create a tracheal stoma.

"PDT is generally performed at the bedside in the ICU... periprocedural mortality related to PDT in randomized studies appears to be less than 0.2%."

Current Surgical Therapy 14e; Sabiston Textbook of Surgery

2. Indications and Contraindications

INDICATIONS	CONTRAINDICATIONS (mostly relative)
Prolonged mechanical ventilation (>10-14 days)	Recent anterior neck surgery (<7 days)
Upper airway obstruction	High ventilatory requirements (FiO₂ >70%, PEEP >10 cmH₂O)
Difficult airway / Significant maxillofacial trauma	Elevated intracranial pressure
Neurologic conditions preventing safe extubation (brain injury, SCI, spinal fixation)	Hemodynamic instability
Severe agitation, prolonged altered mental status	Significant coagulopathy (platelets <50,000/mm³, PT/PTT >1.5x control)
Angioedema / Upper airway tumors	Local infection or malignancy at site
Facilitate weaning from ventilator	Morbid obesity (relative - increased risk of accidental decannulation)
Aid secretion clearance	Predicted early mortality

Contraindications are almost all relative and most are temporary (Sabiston Textbook of Surgery).

3. The Percutaneous Tracheostomy Kit - Components

The most widely used commercial kit is the Ciaglia Blue Rhino Percutaneous Tracheostomy Introducer Kit (Cook Medical), which replaced the original serial dilator technique.

Percutaneous Tracheostomy Set - Cook Medical

Figure: Percutaneous Tracheostomy Set (Scott-Brown's Otorhinolaryngology Head & Neck Surgery)

Essential Components of the PDT Kit:

#	Component	Purpose
1	Introducer needle (18G) with cannula	Initial tracheal puncture and cannulation
2	10 mL syringe (saline-filled)	Confirms intratracheal placement by air aspiration
3	J-tipped guidewire (Seldinger wire)	Guides all subsequent dilators into trachea
4	Short guiding catheter (12 Fr)	Initial small-bore dilation; stiffens the system for subsequent steps
5	Single tapered dilator - Blue Rhino (hydrophilic coated)	Single-step progressive dilation - replaces serial graduated dilators
6	Tracheostomy tube with inner cannula, cuff, and 15 mm adapter	Final airway device placed into trachea
7	Loading dilator / obturator	Mounts tracheostomy tube for smooth introduction over guidewire
8	#11 scalpel blade	Skin incision (1-1.5 cm)
9	Tracheostomy tube holder/tape	Secures tube after placement
10	Lubricant (water-soluble)	Facilitates smooth advancement of dilators

Additionally required but NOT always in kit (must be arranged separately):

Flexible fibreoptic/video bronchoscope (mandatory in current practice)
1% Lignocaine with 1:100,000 adrenaline (local infiltration)
Sedation agents (propofol/midazolam + fentanyl/remifentanil + NMB)
Sterile drapes, gloves, towels
Suction device, monitoring equipment

"Serial dilation has been replaced by use of a single tapered dilator with a hydrophilic coating (Ciaglia Blue Rhino Percutaneous Tracheostomy Introducer Kit, Cook Medical), which allows for faster dilation and less instrumentation."

Cummings Otolaryngology Head and Neck Surgery

4. Variants / Types of PDT Kits

Technique	Kit/Device	Principle
Ciaglia Blue Rhino (most common)	Cook Medical	Single tapered hydrophilic dilator over guidewire
Ciaglia classic (original)	Cook Medical	Multiple serial graduated dilators over guidewire
Griggs technique	Portex GWDF set	Guidewire Dilating Forceps - spreads tissue
Fantoni Translaryngeal	Mallinckrodt TLT	Retrograde pull-through technique
PercuTwist	Rusch-Teleflex	Single-step screw-in rotating dilator
Rapitrac / BlueDolphin	Various	Balloon dilation technique

5. Patient Preparation and Anesthesia Management

Pre-procedure Assessment:

Review neck anatomy - palpate hyoid, thyroid cartilage, cricoid, tracheal rings 1-3
Review CT imaging for vascular anatomy (high-riding innominate artery, aberrant vessels)
Ultrasound of neck to identify vessels in the path of cannulation (now standard)
Lab work: Platelets, PT, PTT, BUN (uremia → treat with DDAVP before procedure)
FiO₂ increased to 1.0 just before the procedure

Anesthesia Protocol:

Sedation + Analgesia + Short-acting NMB (preferred): Propofol infusion + Fentanyl/Remifentanil + Cisatracurium/Succinylcholine
Prevents coughing, patient movement, and optimizes first-attempt success
Role of anesthesiologist: positioned at head of bed - manages ETT, performs bronchoscopy, administers medications
A dedicated non-sterile circulating nurse must be available for monitoring and medication administration

6. Step-by-Step Technique (Ciaglia Blue Rhino)

(Box 7.3 - Cummings Otolaryngology; Current Surgical Therapy 14e)

Position: Supine, shoulder roll placed, neck extended (unless contraindicated - e.g., cervical spine injury)
Landmark identification: Hyoid, thyroid cartilage, cricoid, tracheal rings 1-3
Asepsis: Sterile prep and drape; FiO₂ increased to 100%
Local infiltration: 5-10 mL of 1% lignocaine + 1:100,000 adrenaline subcutaneously (for vasoconstriction)
Skin incision: 1-1.5 cm horizontal (or vertical) incision below inferior border of cricoid
Blunt dissection: Hemostat dissection in midline through subcutaneous tissue to reach tracheal rings
Bronchoscope placement: Flexible bronchoscope advanced through ETT to distal end; ETT withdrawn to level of vocal cords (so the tip is just above the stoma site)
Needle puncture: 18G introducer needle on saline-filled syringe inserted between tracheal rings 1-2 or 2-3 in the midline. Correct position confirmed by:
- Free aspiration of air through saline (seen as bubbles)
- Direct bronchoscopic visualization (needle visible at 10-2 o'clock position on anterior wall)
Catheter advancement: Needle withdrawn, catheter left in trachea
Guidewire insertion: J-tipped guidewire passed through catheter into trachea (directed caudally)
Initial dilation: 12 Fr guiding catheter used for initial tract dilation
Blue Rhino dilation: Lubricated single tapered dilator advanced over guidewire + guiding catheter with steady rotational pressure - creates the final stoma in one pass
Tracheostomy tube insertion: Appropriate-sized tracheostomy tube (usually size 7-8) loaded on obturator over the guidewire and advanced into trachea under bronchoscopic visualization
Confirmation: Guidewire and obturator removed; cuff inflated; connection to ventilator circuit; confirmed by:
- Capnography (EtCO₂)
- Bilateral auscultation
- Adequate tidal volumes without leak
Securing: Tube secured with neck strap (one finger-breadth gap) + sutures to neck plate

7. Anesthesiologist's Critical Role During PDT

The anesthesiologist manages the "shared airway" during PDT:

Ensures adequate sedation/analgesia/paralysis throughout
Withdraws ETT to level of vocal cords at appropriate step (critical - too deep prevents guidewire access, too high risks accidental extubation)
Operates bronchoscope for real-time guidance
Monitors for desaturation, hypotension, arrhythmias
Maintains ventilation throughout - when bronchoscope is in situ, PEEP decreases and auto-PEEP may build
Ensures 100% FiO₂ before, during, and after the critical steps
Ready for emergency re-intubation at all times

8. Bronchoscopic Guidance - Why It Is Mandatory

Confirms correct intratracheal needle placement (prevents paratracheal insertion)
Protects the posterior membranous wall of the trachea from injury
Identifies inadvertent guidewire malposition
Confirms tracheostomy tube is within trachea and above carina
Complication rate without bronchoscopy: 16.8% vs. with bronchoscopy: 8.3% (Cummings)
Bronchoscopy is the standard of care for all PDT procedures

9. Complications

Early Complications:

Complication	Notes
Hemorrhage	Most common; usually minor stoma bleeding; significant hemorrhage rare (~0.03% in large series)
Paratracheal insertion	Prevented by bronchoscopic guidance
Posterior tracheal wall injury / perforation	Most serious intraoperative complication
Accidental decannulation	Increased risk in obesity (BMI >30); if occurs, re-intubate orally first, do not blindly reinstate tube
Pneumothorax	~0.85%; subcutaneous emphysema ~1.4%
Pneumomediastinum	Rare
Tracheal ring fracture	More common in PDT than open tracheostomy
Airway fire	Rare (more common in surgical tracheostomy using electrocautery)
Hypoxemia / desaturation	During bronchoscope use and tube exchange
False passage / esophageal placement	Avoided by bronchoscopic guidance

Late Complications:

Complication	Notes
Tracheal stenosis	Most significant late complication; "corkscrew stenosis" described specific to PDT (Cummings)
Tracheomalacia	Weakening of tracheal cartilage
Tracheo-innominate artery fistula	Life-threatening; related to inferior placement or high-riding innominate artery
Tracheoesophageal fistula	Rare; related to posterior wall injury
Tracheocutaneous fistula	Stoma does not close after decannulation
Granulation tissue / stomal infection	Common; managed with local wound care
Persistent tracheal scar	Cosmetic concern

"Periprocedural major complication rate of 0.15% and periprocedural mortality rate of less than 0.1%" - Sabiston Textbook of Surgery (3000+ consecutive PDT case series)

10. PDT vs. Open Surgical Tracheostomy

Parameter	PDT	Open Surgical Tracheostomy
Setting	ICU bedside	Operating theatre preferred
Time	Faster	Longer (full surgical setup)
Cost	Less expensive	More expensive
Wound infection	Lower	Higher
Bleeding risk	Similar or lower	Similar (electrocautery available)
Tracheal ring fracture	Higher	Lower (direct visualization)
Posterior wall injury	Higher risk (avoided by bronchoscopy)	Lower (direct vision)
Paratracheal insertion	Risk present	Very rare
Difficult anatomy / coagulopathy	Refer to surgical	Preferred
Evidence	Meta-analysis shows equivalence	Equivalent outcomes

"Meta-analysis has shown equivalence of the techniques" - Scott-Brown's Otorhinolaryngology

11. Timing of Tracheostomy

Early tracheostomy: within 7 days of intubation
Late tracheostomy: after day 7-10
Current evidence (TracMan trial, TRACMAN, PERCUTWIST trials) does not show significant mortality benefit of early vs. late tracheostomy in unselected ICU patients
Decision should be individualized based on clinical trajectory

12. Absolute Pearls for the Examiner

PDT uses Seldinger principle - guidewire-based sequential dilatation
Entry site: between rings 1-2 or 2-3 (above ring 1 = subglottic stenosis; below ring 4 = tracheo-innominate fistula risk)
Ciaglia Blue Rhino = single hydrophilic tapered dilator (current gold standard)
Bronchoscopic guidance is mandatory - reduces complications by half
Anesthesiologist withdraws ETT to vocal cord level before guidewire insertion
If accidental decannulation: secure airway orally first, THEN attempt tube replacement (tract is immature for first 7 days)
Most common late complication: tracheal stenosis
Most feared acute complication: posterior tracheal wall perforation
Contraindicated (relative) at high PEEP (>10) - bronchoscopy worsens ventilation
PDT is more cost-effective than surgical tracheostomy in ICU patients
