A thyroidectomy is a full or partial removal of the thyroid. This type of surgery is important to know about for your Med-Surg exams, because it can be the required intervention for several disorders, including hyperthyroidism, which can result from Graves’ disease. A complication stemming from this surgery is hypoparathyroidism, which we will cover in our next article.
This surgery and the related disorders are covered in our Medical-Surgical Flashcards (Endocrine system).
Medical-Surgical Nursing - Flashcards
Nursing care
Any time you have a patient who has had a surgery on their neck (like a thyroidectomy), consider it a serious threat to their airway! Assess for any laryngeal edema (which could manifest with stridor), and intervene rapidly if you identify that.
Make sure to have easy access to a crash cart, oxygen delivery devices, and an emergency tracheostomy kit.
Patient positioning
When a patient comes back from having their thyroidectomy surgery, place them in a semi-fowler’s position. Sitting totally upright would put the patient at a 90 degree angle, but in a semi-Fowler’s position they are angled between 15 and 45 degrees.
Support their head and neck using either sandbags or pillows to keep everything in a neutral position. You don’t want the patient to hyperextend their neck by bending it too far backwards, or have their head droop down in front. Keep the patient’s head at the midline to avoid disrupting the suture line across their throat.
Bleeding
Lots of blood flows through the thyroid gland, and bleeding is a potentially life-threatening complication after a thyroidectomy. You will want to be monitoring your patient carefully for bleeding following this surgery. Check their wound dressing for blood, and check behind their neck to make sure blood is not pooling behind them
Parathyroid damage
Remember from our anatomy overview of the Endocrine system that the parathyroid glands are 4 glands that basically bedazzle the thyroid gland. The parathyroid glands’ job is to secrete parathyroid hormone (PTH), which causes increased calcium levels.
These glands are tiny, the size of a grain of rice, and are somewhat in-the-way during a thyroidectomy and sometimes they get accidentally nicked or damaged during the surgery. So if the parathyroid glands, whose job it is to indirectly increase blood calcium, get damaged and are unable to do their job, calcium will not be increased to the level it should, and this will result in hypocalcemia.
Hypocalcemia
Calcium is an important electrolyte in the body, and the normal level of calcium (Ca) in the blood is 9-10.5 mg/dL. Calcium levels under 9 mg/dL can indicate hypocalcemia. Besides hypoparathyroidism resulting from parathyroid gland damage, other causes of hypocalcemia can be diarrhea (causes electrolyte loss) and vitamin D deficiency (because vitamin D helps the body absorb calcium).
Signs and symptoms of parathyroid damage are signs and symptoms of hypocalcemia, which includes numbness, tingling around the mouth, muscle twitching, GI upset, and positive Chvostek’s and Trousseau’s signs.
Chvostek’s sign
A Chvostek’s sign is an abnormal reaction to the stimulation of the facial nerve. If you tap the patient’s cheek and their face twitches, this is a positive Chvostek’s sign and can indicate the patient has hypocalcemia. Cathy’s easy way for remembering this is that both Chvostek and cheek start with CH!
Trousseau’s sign
Trousseau’s sign is an abnormal reaction by the hand, to pressure on the arm. If you inflate a blood pressure cuff on a patient’s upper arm and it causes spasms in their hands and fingers due to ischemia, that can indicate hypocalcemia.
Treatment
If a patient does have hypocalcemia that is confirmed with a blood test, we can provide them with calcium gluconate to bring the calcium level up.
Patient teaching
After a patient undergoes a thyroidectomy, it’s important to teach them to avoid extreme neck extension or flexing, and to keep their head in a midline position. Otherwise, they risk damage to that suture line.
As part of patient teaching post-thyroidectomy, you will also need to reinforce that the patient will need to take thyroid replacement for the rest of their lives. Their thyroid gland is now gone, so it will not be producing thyroid hormones T3 and T4 anymore.
The thyroid hormone replacement medication is levothyroxine, which is given on an empty stomach with a full glass of water.
Levothyroxine is one of the essential medications you need to know for your Pharm exams and it’s covered in our Pharmacology flashcards.
Cathy’s teaching on thyroidectomy surgery is intended to help prepare you for Medical-Surgical nursing exams and critical care. The Medical-Surgical Nursing video series is intended to help RN and PN nursing students study for nursing school exams, including the ATI, HESI and NCLEX.

Pretty helpful. Kudos!
I am a retired RN. My brother just had. Thyroidectomy, Cancer, He is coming to my house for care. I read the article and it was very helpful, a good refresher for me. Thank you so much.
Well done reviews
Thank you so much❤️
thank you very helpful !!!
