Neck Tightness and Stridor After Total Thyroidectomy
Ms. L, 44, is 70 minutes into Phase I recovery after a total thyroidectomy for a large multinodular goiter. Her initial recovery was uneventful and her voice is unchanged. She now reports a "tight" feeling in her neck. The dressing is dry and intact, but inspiratory stridor is audible at the bedside and has worsened over five minutes. HR 122, BP 162/94, SpO2 92% on room air, RR 26 with tracheal tug. She is anxious and keeps trying to sit upright. You are the only RN in a six-bay Phase I unit; the second RN is in the operating room. The surgeon is operating in another room in the main suite.
1. Rank the likely causes of her stridor and neck tightness, and state which findings argue for and against each.

Working diagnosis: expanding cervical hematoma until proven otherwise.
- Hematoma - for: neck tightness, new and progressive stridor, tachycardia and hypertension (catecholamine response to hypoxemia), onset within the first six hours. Against: the dressing is dry and intact - but blood tracks internally, so a dry dressing does not exclude it.
- Laryngeal edema - for: airway manipulation during neck surgery; against: usually earlier and less abrupt. It cannot be reliably separated from hematoma at the bedside, and initial management overlaps.
- Bilateral vocal cord paralysis - for: stridor; against: onset is typically immediately after extubation, unilateral injury would cause hoarseness (her voice is unchanged), and it does not cause neck fullness.
- Laryngospasm - for: stridor and hypoxemia; against: usually on emergence, is an active cord closure without neck tightness, and does not progressively worsen over minutes with a rising tracheal tug.
- Tracheomalacia - for: large goiter with tracheal compression; against: typically presents at extubation, is position-related (worse with flexion), and does not cause neck fullness.
- Hypocalcemia - for: thyroidectomy; against: usually 24-72 hours later with perioral tingling, carpopedal spasm, positive Chvostek/Trousseau, and QT prolongation. It could only cause stridor through laryngospasm, which would not produce a tight neck.
Reasoning: severity drives the decision. Neck tightness plus progressive stridor plus tachycardia plus tracheal tug means mechanical airway compromise that is evolving minute to minute. It will not respond to reassurance or an anxiolytic, and waiting to distinguish the causes could cost the airway.
2. You are the only RN in the unit. What do you do in the first three minutes, and what do you delegate?
Read the worked answer
- Stay at the head of the bed - do not leave the patient. Call for help loudly (overhead page/rapid response, surgeon, anesthesia); the second RN can bring the airway cart.
- Open the wound. Remove the dressing and cut the skin sutures or clips at the bedside with sterile gloves and suture scissors to decompress the neck. This is the fastest way to relieve pressure and can be lifesaving; it is done under emergency protocol without waiting for the surgeon.
- Position and oxygen: keep her upright or head-up 45 degrees - she is already self-positioning, so follow her lead - high-flow oxygen, continuous oximetry and capnography.
- Prepare for a difficult airway: working suction, bag-mask, oral and nasal airways, video laryngoscope, and a cricothyrotomy set. Blood and distorted anatomy make intubation hard; the surgeon may need to secure the airway surgically.
- Delegate explicitly: one person to call the surgeon and anesthesia with a precise message ("post-thyroidectomy hematoma, wound opened, progressive stridor, come now"), one to bring the airway cart and blood, one to draw CBC/coags and send a type and screen, one to record times and vital signs every 2-3 minutes.
- Do not give a sedative to "calm her down" - it blunts the respiratory drive and the ability to protect her airway at the moment she needs both.
3. Later that day, with no stridor and SpO2 99%, she reports perioral tingling and her hands "cramp." What is your assessment and plan?
Read the worked answer
Most likely hypocalcemia from parathyroid manipulation or devascularization - not anxiety.
- Assess for Chvostek and Trousseau signs, look at the QT interval on the monitor (prolongation supports hypocalcemia), and obtain ionized calcium and magnesium. Notify the surgeon promptly.
- Anticipate IV calcium gluconate per order with continuous ECG monitoring through a well-checked line (extravasation causes serious tissue injury); mild cases may be managed with oral calcium and vitamin D.
- Keep the airway in mind: hypocalcemia can precipitate laryngospasm and stridor, so suction and airway equipment stay at the bedside.
- Differentiate: anxiety with hyperventilation also causes tingling, but ionized calcium and the QT interval are normal and the symptoms resolve with slowed breathing. Do not label this anxiety when the surgical anatomy fits hypocalcemia.
- Teach before discharge: report numbness, twitching, or cramping; understand calcium supplement timing; monitor the incision; and call emergency services for neck swelling, difficulty swallowing, or noisy breathing.
