Which methods are used to confirm endotracheal tube placement during neonatal resuscitation?

• A. Chest X-ray, auscultation with stethoscope, CO2 detector, and visualization through the cords
• B. Pulse oximetry alone
• C. Capnography without auscultation
• D. Visual inspection of the chest only

Answer: (A)

Confirming endotracheal tube placement in neonatal resuscitation relies on using multiple checks because each method has limitations and the newborn’s condition can change quickly. Visualizing the tube as it passes through the vocal cords provides direct confirmation that you’re entering the trachea, not the esophagus. After placement, auscultation with a stethoscope helps by revealing bilateral, equal breath sounds and appropriate chest rise, supporting tracheal placement. A CO2 detector or capnography detects exhaled CO2, which strongly indicates the tube is in the trachea, though it’s best interpreted alongside other signs. Finally, chest X-ray offers radiographic confirmation of the tube tip’s position relative to the carina and is used to verify placement definitively when imaging is available. Relying on a single sign, such as pulse oximetry alone, lacks information about tube location, and using capnography without any auscultation or X-ray confirmation can be misleading in some cases. Visual inspection of the chest alone can be unreliable, since chest movement doesn’t guarantee correct tracheal placement. Using all these approaches together provides the most reliable confirmation during neonatal resuscitation.
