Which laryngoscope blade size is used for a term newborn during neonatal intubation?
Answer: Size 1 (straight Miller blade)
A size 1 straight (Miller) blade is used for term newborns; a size 0 blade is reserved for very preterm infants.
What endotracheal tube (ETT) inner diameter is appropriate for a term newborn (≥38 weeks)?
Answer: 3.5 mm
A 3.5 mm ID ETT is recommended for term infants ≥38 weeks gestation; smaller tubes are used for preterm infants.
During intubation, which landmark confirms the tube is passing through the vocal cords?
Answer: The vocal cord guide (black line) at the level of the cords
The vocal cord guide is a black line printed on the ETT; it should be positioned at the level of the vocal cords during insertion.
How long should an intubation attempt last before pausing to ventilate?
Answer: No more than 30 seconds
Each intubation attempt should be limited to 30 seconds; if unsuccessful, resume PPV before retrying.
What is the most reliable primary confirmation of correct ETT placement?
Answer: Detection of exhaled CO₂ with a colorimetric detector
A colorimetric CO₂ detector that changes color with exhaled CO₂ is the most reliable primary confirmation of tracheal placement.
At what depth (lip-to-tip) should a 3.5 mm ETT be placed in a 3 kg term newborn?
Answer: ~9–10 cm at the lip
A useful estimate is 6 cm + weight in kg; for a 3 kg infant: 6 + 3 = 9 cm at the lip.
