Abstract
A 73-year-old woman presented to the emergency department with submandibular pain and swelling. The patient was diagnosed to have Ludwig’s angina, and she was planned to undergo urgent incision and drainage under general anesthesia. However, her physical examination revealed severe diffuse swelling extending from the bilateral submandibular spaces to the submental space and further down to the neck. As our view was blocked by the patient’s neck swelling, we did not perform a regional anesthesia of the airway or a transtracheal block. Several non-invasive alternatives were considered. The “spray-as-you-go” technique was chosen, and it was performed using the OptiScope®. However, the OptiScope did not have a working channel or syringe adaptor for the administration of the local anesthetic solution. To solve this problem, we combined the OptiScope with a 27-G tunneled epidural catheter (100 cm) for the administration of lidocaine and this combination made the awake intubation successful.
Key Words : Awake intubation, Difficult intubation, Epidural catheter, Ludwig’s angina, OptiScope, Spray-as-you-go.
