Situation: A 34-year-old woman with Graves disease is admitted for total thyroidectomy because a large goiter makes swallowing difficult. She has taken methimazole for 3 months, and potassium iodide solution was added 9 days ago. She has no known drug allergies.

Six hours after the thyroidectomy, the nurse assesses her. Which finding should the nurse act on FIRST?

## 해설

Blood collecting behind the neck with a sense of tightness points to an expanding hematoma, which can compress the trachea within minutes; airway comes first, so the nurse checks for stridor and calls the surgeon or rapid response team. Tingling suggests falling calcium and needs prompt follow-up, but it usually develops over hours. Mild hoarseness and incision pain are common after surgery.

## 심화 해설

Priority setting after thyroidectomy

The first six hours after total thyroidectomy are the highest-risk window for a post-thyroidectomy cervical hematoma. Blood pooling deep to the strap muscles and platysma can expand rapidly because the neck has no rigid compartment to tamponade bleeding. As the hematoma enlarges, it displaces the trachea and larynx and compresses the soft tissues of the upper airway. The earliest clinical clues are often subtle: a sense of neck tightness or pressure, blood oozing onto the pillow, and sometimes a visible change in neck contour. Airway compression from an expanding hematoma can progress from mild discomfort to complete obstruction within minutes, so any sign of active bleeding with a sensation of tightness must be treated as an airway emergency until proven otherwise.

The pathophysiology is mechanical. The thyroid bed is highly vascular, and even small vessel oozing can accumulate behind the closed incision. Because the overlying skin and muscle layers are sutured, the blood tracks into the deep cervical spaces rather than draining freely. Rising pressure then narrows the pharyngeal and laryngeal lumen. In severe cases, this produces a “cannot intubate, cannot ventilate” situation because glottic edema and distortion make both bag-mask ventilation and laryngoscopy difficult [1][2]. That is why the nurse’s first action is not to wait for stridor or oxygen desaturation. Key point! The priority is to assess for stridor and respiratory distress immediately, then call the surgeon or rapid response team while preparing for emergency bedside wound opening and hematoma evacuation if ordered.

The other options are real postoperative concerns but do not carry the same immediate threat. Tingling in the fingertips and around the lips suggests hypocalcemia from parathyroid manipulation or devascularization. It is an important finding that requires prompt serum calcium measurement and likely calcium replacement, but hypocalcemia typically evolves over hours to days, not minutes. Hoarseness and a weak voice are common after thyroidectomy because the recurrent laryngeal nerve is manipulated during dissection; this may be transient neuropraxia or edema and is expected in the early postoperative period. Incision pain rated 6 out of 10 on swallowing is also an anticipated consequence of a neck incision and should be managed with analgesia, but it does not indicate impending airway loss.

| Finding | Mechanism | Priority | Nursing action |
| --- | --- | --- | --- |
| Blood on pillow with neck tightness | Expanding cervical hematoma compressing the trachea and larynx | Highest — airway emergency | Assess for stridor and respiratory distress; call surgeon or rapid response team; prepare for bedside wound opening |
| Tingling around lips and fingertips | Hypocalcemia from parathyroid injury or ischemia | High but less immediate | Check serum calcium; monitor for tetany and laryngospasm; prepare calcium replacement |
| Hoarse, weak voice | Recurrent laryngeal nerve edema or neuropraxia | Expected early after surgery | Monitor voice quality and airway; reassure patient |
| Incision pain 6/10 on swallowing | Surgical tissue trauma and edema | Routine postoperative pain | Administer prescribed analgesia; support neck during swallowing |

The time course matters. A hematoma can become life-threatening as early as 4 hours after surgery, and cases of severe airway obstruction with cyanosis and loss of responsiveness have been reported within that window [2]. The patient in this scenario is at 6 hours, which places her squarely in the period when a hematoma would be declaring itself. Watch out! Do not be reassured by the absence of visible neck swelling. Blood can collect posteriorly and deep to the strap muscles, so the patient may feel tightness before any obvious bulge appears. The pillow may show only a small amount of blood while a much larger volume is trapped in the neck.

The literature reinforces that early recognition and immediate intervention are the only factors that change outcomes. Once a post-thyroidectomy hematoma progresses to respiratory failure, airway management becomes extremely difficult because laryngeal edema distorts anatomy and makes both intubation and ventilation challenging [1][2]. Emergency management centers on bedside wound opening and hematoma evacuation to relieve pressure on the airway, followed by definitive surgical control of bleeding in the operating room [2]. Drains placed at surgery do not reliably prevent this complication, and their routine use remains debated, so the nurse cannot assume that a drain makes the patient safe . The clinical triad of bleeding, neck tightness, and any change in voice or breathing must trigger an immediate airway-focused assessment and escalation, because the window between early signs and complete obstruction can be only minutes.References (research sources)

Post-Thyroidectomy Airway EmergencyRecognizing Expanding Cervical Hematoma
The first 6 hours after total thyroidectomy are the highest-risk window for cervical hematoma. Blood pooling deep to the strap muscles expands rapidly because the neck has no rigid compartment to tamponade bleeding.

Earliest clues are subtle: blood on the pillow, a sense of neck tightness or pressure, and sometimes a visible change in neck contour. Airway compression can progress from mild discomfort to complete obstruction within minutes.

CautionDo not wait for stridor or oxygen desaturation. Assess for stridor and respiratory distress immediately, and call the surgeon or rapid response team. Severe cases can become a cannot intubate, cannot ventilate situation due to glottic edema and airway distortion.

- **Cervical hematoma** — Blood collection in the neck after thyroid surgery that can rapidly expand and compress the trachea, causing airway obstruction
- **Airway emergency** — A clinical situation where the patient's breathing is at immediate risk, requiring rapid assessment and intervention before other concerns
- **Hypocalcemia** — Low serum calcium from parathyroid gland injury or removal during thyroidectomy, presenting with tingling, muscle cramps, or tetany
- **Stridor** — A high-pitched inspiratory sound indicating upper airway narrowing or obstruction
- **Total thyroidectomy** — Complete surgical removal of the thyroid gland, commonly performed for Graves disease, large goiter, or thyroid cancer
