Summary

Capnography failed to detect esophageal intubation in a spontaneously breathing patient due to a unique mechanism involving a cuffed airway. This case highlights limitations of capnography in specific airway management scenarios.

Area of Science:

  • Anesthesiology
  • Airway Management
  • Patient Safety

Background:

  • Difficult intubation due to anatomical changes post-surgery and radiation.
  • Attempted nasotracheal intubation was unsuccessful, necessitating alternative strategies.

Observation:

  • Esophageal intubation was initially undetected by capnography, showing normal CO2 waveforms.
  • Spontaneous breathing through a cuffed oropharyngeal airway complicated initial detection.
  • Tracheal tube cuff inflation led to the disappearance of CO2 waveforms.

Findings:

  • A case of accidental esophageal intubation misdiagnosed by capnography in a spontaneously breathing patient.
  • A proposed mechanism suggests expired gas re-inhalation from the oral cavity into the esophagus.
  • The cuffed airway's role in preventing esophageal intubation detection was critical.

Implications:

  • Capnography may not be reliable in all cases of esophageal intubation, especially with spontaneous breathing and specific airway adjuncts.
  • Highlights the importance of clinical vigilance and multimodal monitoring during airway management.
  • Emphasizes the need for thorough assessment and prompt intervention in difficult airway scenarios.
