Down a wrong path - A nasogastric tube in the lung

Area of Science:

• Medical Procedures
• Patient Safety
• Respiratory Medicine

Background:

• Nasogastric tube insertion is a common bedside procedure.
• Accidental airway placement is usually detected by gag reflex in awake patients.
• Ventilated patients may not exhibit gag reflex, increasing risk of missed airway placement.

Observation:

• A case of nasogastric tube misplacement into a peripheral bronchiole of the right lung is presented.
• The misplacement was initially missed on a standard chest radiograph.
• This highlights a potential failure in diagnostic imaging for nasogastric tube placement.

Findings:

• Nasogastric tube malposition into the airway can occur in ventilated patients.
• Chest radiography has limitations in detecting peripheral bronchial intubation.
• Direct visualization techniques are superior for confirming correct nasogastric tube placement in this population.

Implications:

• Relying solely on chest radiography for nasogastric tube confirmation in ventilated patients can be fallacious.
• Enhanced visualization methods are recommended to prevent complications from malpositioned nasogastric tubes.
• This case underscores the importance of meticulous technique and verification in nasogastric tube insertion for critically ill patients.
