Difficult Ventilation in an Infant After Successful Intubation.

Area of Science:

• Medical Devices
• Pediatric Critical Care
• Anesthesiology

Background:

• Manufacturing defects in endotracheal tubes (ETTs) are uncommon.
• Such defects, particularly in the connector, can lead to partial or complete airway obstruction.
• This poses a significant risk in infants with limited physiological reserves.

Purpose of the Study:

• To highlight a case of complete airway obstruction caused by an ETT manufacturing defect.
• To emphasize the importance of pre-use inspection of ETTs.
• To recommend a method for routine ETT defect detection.

Main Methods:

• A case report detailing a patient experiencing airway obstruction post-intubation.
• Description of a routine ETT check involving passing a stylet through the tube.
• Review of the specific manufacturing defect identified in the ETT connector.

Main Results:

• A patient developed complete airway obstruction immediately following intubation.
• The obstruction was directly attributed to a manufacturing defect in the endotracheal tube connector.
• The defect was discoverable through a pre-use check with a stylet.

Conclusions:

• Manufacturing defects in ETT connectors, though rare, can have severe consequences.
• Rigorous pre-use inspection of endotracheal tubes is essential.
• Using a stylet for routine checks can help identify potential defects, preventing critical airway events.
