Post-Thyroidectomy Neck Hematoma: Awake Airway or Immediate Decompression?
A 45-year-old woman underwent total thyroidectomy for a multinodular goiter and is now 18 hours postoperatively on the surgical ward. She has progressive neck swelling, a muffled voice, and inspiratory stridor that has worsened over 30 minutes. SpO2 is 93% on room air, respiratory rate 28/min, heart rate 118/min, and blood pressure 158/92 mmHg. She is anxious and refuses to lie flat; her neck is tense and ecchymotic. The surgical intern has been called but is not yet at the bedside, and the ward has no difficult-airway cart. The anesthesiologist on call is asked to 'come and intubate' while the patient is being wheeled toward the CT scanner for a neck CT. There is no documented difficult airway, and her previous intubation was grade 1 with a Macintosh blade.
1. What are your immediate priorities before any attempt at intubation? Explain why the CT scanner is not the right destination.

The priority is to recognize a developing airway emergency from a neck hematoma and to prevent complete obstruction. I would call for immediate help from anesthesia, surgery, and nursing, and I would have the surgeon open the neck wound at the bedside to evacuate the hematoma. Wound decompression can relieve venous congestion and laryngeal edema and may be lifesaving before any airway instrumentation. I would give 100% oxygen, keep the patient sitting upright, apply monitors, and prepare difficult-airway equipment and a surgical airway kit. I would not send her to CT, because the airway can obstruct completely during transport or in the scanner, and imaging will not change the immediate need for decompression.
The previous grade 1 intubation is falsely reassuring because the anatomy is now distorted by hematoma and edema. The judgement is that this is a surgical airway emergency first and an intubation problem second; opening the wound is faster and safer than moving the patient.
2. Describe your airway plan if the hematoma is evacuated but intubation is still required. How would you manage a cannot-intubate, cannot-oxygenate situation?

After decompression, I would reassess the airway and plan an awake fibreoptic intubation or an inhalational induction with sevoflurane while maintaining spontaneous ventilation. I would avoid neuromuscular blockade until the airway is secured, because losing spontaneous ventilation in a patient with laryngeal edema can be catastrophic. I would have a video laryngoscope, a smaller endotracheal tube, suction, and a surgeon scrubbed and ready for immediate tracheostomy. If fibreoptic intubation fails, I would proceed to direct or video laryngoscopy with a bougie, but I would keep the patient breathing.
If the patient cannot be intubated and cannot be oxygenated, I would call for an emergency front-of-neck airway and proceed with surgical cricothyrotomy or tracheostomy, depending on the anatomy and the surgeon's availability. Needle cricothyrotomy is a temporizing measure. The key judgement is to avoid a paralytic induction in an obstructed airway and to have a surgical airway plan before starting.
3. After the airway is secured and the hematoma is evacuated in the operating room, what postoperative concerns remain?
Read the worked answer
The patient needs ICU monitoring because rebleeding can occur and because laryngeal edema may persist for hours. I would keep the head elevated, monitor the neck circumference and drain output, and ensure the surgeon is immediately available. I would check calcium and watch for signs of hypocalcemia, because the original thyroidectomy may have caused parathyroid dysfunction, and I would monitor for recurrent laryngeal nerve injury and stridor after extubation. Extubation should be planned with a cuff-leak test and with difficult-airway equipment at the bedside.
I would also document the event and review the surgical technique and ward monitoring, because a post-thyroidectomy hematoma is a preventable airway catastrophe. The judgement is that securing the airway is only the first step; the postoperative period carries a continuing risk of reobstruction and bleeding.
