Question

For babies weighing less than 1,000 g, the ETT size should be___________.

1) 2.5
2) 3.0
3) 3.5
4) 4.0

Answer 1

Endotracheal tube (ETT) size for babies weighing less than 1,000 g should be 2.5 to ensure proper ventilation and minimize complications.

Step-by-step explanation:

For babies weighing less than 1,000 g, the ETT size should be 2.5. This is because extremely low birth weight infants require appropriately sized endotracheal tubes to ensure adequate ventilation and airway management. Pre-term infants have not had the same length of prenatal growth as full-term infants, who weigh an average of about 3.4 kg and may therefore need larger ETT sizes. The selection of an ETT size is crucial for providing effective respiratory support and minimizing the risk of complications.
