What is the most likely cause of tetany after thyroidectomy?
What causes tetany? Tetany can be the result of an electrolyte imbalance. Most often, it’s a dramatically low calcium level, also known as hypocalcemia.
What is tetany after thyroidectomy?
Overt or clinical tetany is characterized by triad of carpopedal spasm stridor and convulsion. Stridor is caused by spasm of glottis. Adults complain of tingling in the hands feet and around the mouth1.
When does hypocalcemia occur after thyroidectomy?
Transient hypocalcemia, often observed after the operation, generally responds favourably to replacement therapy within a few days or weeks 1. Hypocalcemia is considered permanent when it does not return to normal within 6 months (1.3-3% of cases) 2.
Is hypocalcemia common after thyroidectomy?
Hypocalcemia after thyroidectomy is the most common complication, with the reported incidence of transient and permanent hypocalcemia ranging from 3% to 52% and 0.4% to 13%, respectively.
What are the symptoms of tetany?
Symptoms of tetany include:
- Muscle spasms.
- Laryngospasm — which causes muscle spasms in your vocal cords, making speaking and breathing difficult.
- Numbness in your hands and feet.
- Seizures.
- Heart problems.
- Carpopedal spasm, a hand spasm when your blood pressure is taken.
What happens if you don’t take calcium after thyroidectomy?
Hypocalcemia: low calcium levels in the blood, a complication from thyroid surgery that is usually shortterm and relatively easily treated with calcium pills. If left untreated, low calcium may be associated with muscle twitching or cramping and, if severe, can cause seizures and/or heart problems.
Which assessment findings after thyroid surgery indicates hypocalcemia?
Most patients who are hypocalcemic after thyroidectomy are initially asymptomatic. Symptoms and signs of hypocalcemia include circumoral paresthesias, mental status changes, tetany, carpopedal spasm, laryngospasm, seizures, QT prolongation on ECG, and cardiac arrest.
How do you assess tetany?
A tetany diagnosis is usually confirmed by evidencing low calcium levels in the blood. In addition, blood levels of parathyroid hormone (PTH), vitamin D, magnesium, and phosphorus may help identify the underlying cause of tetany in an individual.
What are the two classic signs of tetany How would you elicit them?
Cramps, Muscle Stiffness, and Exercise Intolerance The initial symptom of tetany is tingling around the mouth and in the hands and feet. With time, the tingling increases in intensity and becomes generalized.
How do you prevent hypocalcemia after thyroidectomy?
Brief Summary: the increased risk of hypocalcemia following total thyroidectomy plus central neck dissection can be minimized by routine administration of oral calcium and vitamin D supplements during the early postoperative period.
What do you monitor after thyroidectomy?
It is important to monitor both calcium and magnesium levels after total thyroidectomy and to correct deficiencies to facilitate prompt resolution of symptoms.
What should I check after thyroidectomy?
You might also have to take supplements after thyroidectomy to balance your calcium levels. After a thyroid lobectomy, you’ll need to have your thyroid hormone levels checked and will be prescribed a thyroid hormone replacement, if needed.
What should I monitor after thyroidectomy?
How do you check for tetany?
The Trousseau sign of latent tetany is a way to determine if an individual may have hypocalcemia. Trousseau’s sign is considered positive when a carpopedal spasm of the hand and wrist occurs after an individual wears a blood pressure cuff inflated over their systolic blood pressure for 2 to 3 minutes.
