Airway sizes (peds)

(Redirected from Airway Sizes (Peds))

See critical care quick reference for airway sizes by weight.

Airway Adjuncts

Airway Placement
Nasopharyngeal Tip of nose to tragus
Oropharyngeal From lip/teeth to angle of jaw
Bag valve mask 10cc/kg

Endotracheal tube Size

ETT Size: (Age/4) + 4 for uncuffed, (Age/4) + 3.5 for cuffed

  • Estimates cuffed
  • 1 yr, 10kg, size 4
  • 5 yr, 20kg, size 5
  • 10 yr, 30 kg, size 6
  • Cuffed and uncuffed ETT are acceptable outside neonatal age
    • Uncuffed
      • <1yo - 3.5mm ETT
      • 1-2yo - 4mm ETT
      • >2yo - 4 + (age/4)
    • Cuffed
      • <1yo - 3mm ETT
      • 1-2yo - 3.5mm ETT
      • >2yo - 3.5 + (age/4)
  • Depth of Tube Placement: 3 x uncuffed ETT size (cm)
    • Neonate: Nasal septum to tragus in cm + 1 cm

Preemies

  • 1kg 2.5mm tube at 7 cm depth
  • 2kg 3.0mm tube at 8 cm depth
  • 3kg 3.5mm tube at 9 cm depth

There is no evidence to support the routine use of atropine as a premedication to prevent bradycardia in emergency pediatric intubations[1]

Relation to Other Tubes

  • NG, OG, foley = 2 x ETT
  • Chest Tube (max) = 4 x ETT

Endotrachial Drug Delivery

Endotracheal Drug Delivery: 1:1000 solution at 0.1mg/kg = 0.1ml/kg
Newborn: 1:10,000 solution at 0.03mg/kg = 0.3mL/kg
