Overview
Needle Ventilation in a Pediatric CICO Situation
Needle ventilation is an emergency airway intervention used as a temporizing measure in a can’t intubate, can’t oxygenate (CICO) scenario when conventional methods of oxygenation and ventilation have failed. In pediatric patients, the airway is more delicate, making surgical airway techniques riskier. Needle ventilation—though not a definitive solution—buys time by allowing some oxygenation and CO₂ clearance until a more secure airway is established.
Key Steps of Pediatric Needle Ventilation
1. Identify the Landmarks
- Place the patient supine with the neck in a neutral or slightly extended position.
- Palpate the cricothyroid membrane (located between the thyroid and cricoid cartilage).
- In infants and small children, the cricothyroid membrane may be underdeveloped—if difficult to locate, use the lower trachea as a backup site.
2. Prepare Equipment
- 14–18 gauge over-the-needle catheter (18G for neonates, 16-14G for older children)
- 5 mL syringe pre-filled with saline
- High-pressure oxygen source (e.g., jet ventilator, bag-valve mask with a Luer-lock adapter, or modified 3-way stopcock)
- Scalpel (in case conversion to a surgical airway is needed)
- Sterile gloves and antiseptic solution
3. Access the Airway
- Clean the skin with an antiseptic.
- Attach the needle to the saline-filled syringe.
- Insert the needle at a 45-degree angle caudally (toward the feet) while aspirating.
- A sudden rush of air and bubbling of saline confirms tracheal entry.
4. Advance the Catheter
- Once in the trachea, advance the catheter over the needle.
- Remove the needle, leaving the catheter in place.
- Secure the catheter with tape or a stabilizing device.
5. Provide Ventilation
- Connect the catheter to a jet ventilator or bag-valve mask (via a Luer-lock adapter or modified 3-way stopcock).
- Deliver oxygen using intermittent low-pressure insufflation (e.g., 1 second of insufflation, 4 seconds of exhalation).
- Monitor chest rise, oxygen saturation, and avoid barotrauma.
6. Transition to a Definitive Airway
- Needle ventilation is a temporary measure due to its poor CO₂ clearance.
- Immediately prepare for definitive airway management (e.g., endotracheal intubation, surgical cricothyroidotomy in older children, or tracheostomy in infants).
Key Considerations & Pitfalls
- Risk of Barotrauma: Jet ventilation can cause pneumothorax, especially if exhalation is obstructed.
- Poor CO₂ Clearance: Hypercapnia can develop quickly; prioritize securing a definitive airway.
- Failure to Locate Cricothyroid Membrane: Consider lower trachea if cricothyroid access is difficult.
- Transition to Surgical Airway May Be Necessary: If needle ventilation is ineffective, escalate quickly to a surgical airway in an older child.
How to Ventilate
Once you’ve placed the needle or catheter into the trachea in a pediatric CICO situation, ventilation must be performed carefully to avoid complications like barotrauma. Here’s how:
1. Connect to a Ventilation System
- Preferred setup: A high-pressure oxygen source, such as a jet ventilator, is ideal.
- If a jet ventilator is unavailable, use a bag-valve mask (BVM) with a Luer-lock adapter or a modified 3-way stopcock to deliver oxygen through the catheter.
2. Use a Safe Ventilation Pattern
- DO NOT OVERPRESSURIZE
- Jet ventilation settings (if available):
- Inspiratory time: ~1 second
- Expiration time: At least 4 seconds (to allow passive exhalation)
- Oxygen flow: 1–2 L/kg/min (adjust based on chest rise and saturation)
- If using manual ventilation (BVM or O2 tubing with a stopcock):
- Deliver short, quick bursts of oxygen (~1 second per breath).
- Allow time for exhalation, as passive airflow occurs through the upper airway.

We suggest you watch this great video on transtracheal ventilation with a Ventrain (we have no financial interest) and become familiar with the device you have at your institution. Larry Mellick MD is another great learning resource we think you should add to your network.
The Bottom Line
Needle ventilation is a life-saving, last-resort maneuver in pediatric CICO situations. However, it should be used only as a bridge to definitive airway management due to its limitations. Rapid team coordination is essential to ensure successful oxygenation while securing a more stable airway.
