Road traffic accident (RTA) is a modern-day epidemic which involves multiple challenges for anesthesiologists. A 40-year-old male was admitted to our emergency department with a history of RTA, and he was conscious, alert, and hemodynamically stable, with a respiratory rate of 20 and 97% saturation on room air. The patient had a bilateral tibial fracture, and focused assessment with sonography for trauma scan was negative. There was mild subcutaneous emphysema with bruise all over the neck. Immediate computed tomography (CT) head and neck was done, which revealed CT head as normal but neck showed completely dissected anterior and lateral tracheal walls with lacerated posterior tracheal wall.
Hence, emergency tracheal repair was planned. A comprehensive plan for anesthesia and surgery was discussed among anesthesiologists and surgeons. It was a difficult airway emergency in which direct laryngoscopy and intubation and fiber-optic bronchoscope by railroading of tube and manipulation could have completely dissected trachea and lead to complete loss of airway [Figure 1]. Hence, we planned to proceed for primary tracheal repair under local anesthesia (LA) with monitored anesthesia care. Glycopyrrolate 0.2 mg, ranitidine 50 mg, and metoclopramide 10 mg were given intravenous (IV) as prophylaxis to prevent secretions and to decrease the risk of acid aspiration, respectively. As the patient came to the emergency department during morning hours and had dinner at night, so he was adequately fasted. The patient was counseled, and nebulization with 50 mg ketamine and 4 ml of 4% lignocaine was done to anesthetize tracheal mucosa. Using only lignocaine could be an option, but the achievement of complete anesthesia for tracheal repair was doubtful. Hence, we used a combination of ketamine and lignocaine. Airway blocks such as superior nerve block and recurrent laryngeal nerve block were not possible in our case due to transaction of trachea along with gross swelling over the area. Surgeons infiltrated 2% lignocaine over the incision site and started the procedure. It was uneventful, and the patient was stable and comfortable throughout the surgery duration of 45 min. Postoperatively, the patient was shifted to the recovery room for further monitoring.

Airway injuries are a challenge to anesthesiologists and require careful planning and knowledge of the airway tract. Mercer et al. described the management of blunt tracheal trauma as either repair under LA or awake fiber-optic and direct laryngoscopy for intubation to secure the airway. Repair under LA was considered as safest. Direct laryngoscopy or fiber-optic intubation might increase the tear during railroading of tube. Elkoundi et al. also reported ketamine nebulization for awake fiber-optic intubation. We had the only option of LA for tracheal repair so nebulized airway with lidocaine and ketamine. Probably, only lignocaine can be used, but we needed a deeper anesthesia with analgesia, so ketamine was added. The effectiveness of ketamine nebulization could be due to peripheral analgesic effects and attenuation of local inflammation. Literature has proved the effectiveness of ketamine in neuropathic and cancer pain. IV ketamine was our plan B, but our patient was comfortable and co-operative throughout the procedure. We want to emphasize our short communication that nebulized ketamine can be an effective and viable option for airway trauma.
Ketamine with lignocaine can be lifesaving for patients and boon for anesthesiologists in the management of difficult airway scenarios. Further studies should be done to evaluate its efficacy.
