Area of Science:

Medicine
Otolaryngology
Emergency Medicine

Background:

Nasal oxygen catheters are commonly used for respiratory support.
Proper insertion technique is crucial to prevent complications.

Observation:

A 65-year-old male patient developed severe subcutaneous emphysema in the face and neck after nasal oxygen catheter insertion.
The catheter inadvertently damaged the left inferior nasal concha mucosa.

Findings:

Oxygen extravasation into the subcutaneous tissues occurred due to mucosal damage.
The resulting emphysema compromised the patient's airway, necessitating emergency intubation.

Implications:

This case highlights a rare but serious complication of nasal oxygen catheter use.
Emphasizes the importance of meticulous technique and vigilant monitoring during oxygen therapy to prevent tissue damage and airway compromise.
