Summary
This summary is machine-generated.Postoperative hypocalcemia after thyroidectomy can be accurately predicted by parathyroid hormone levels on the first day. Algorithms and correction formulas do not enhance prediction accuracy for hypocalcemia.
Area Of Science
- Endocrinology
- Surgical Complications
- Clinical Chemistry
Background
- Hypocalcemia is a frequent complication following total thyroidectomy.
- Current monitoring relies on serum calcium and parathyroid hormone (PTH) levels.
Purpose Of The Study
- Identify precise predictors of postoperative hypocalcemia.
- Develop a risk assessment algorithm.
- Evaluate the utility of calcium correction formulas.
Main Methods
- Prospective, single-center, non-randomized longitudinal cohort study.
- 205 patients undergoing total thyroidectomy.
- Postoperative sampling of PTH, serum calcium, and ionized calcium.
Main Results
- First postoperative day PTH is the most sensitive predictor of symptomatic hypocalcemia (80.22% sensitivity, cut-off ≤2.03 pmol/L).
- Combined serum calcium and PTH on day one offered highest sensitivity (94%) and specificity (89%) for predicting hypocalcemia.
- Algorithms and correction formulas did not improve prediction accuracy.
Conclusions
- First postoperative day PTH is the most sensitive predictor for symptomatic hypocalcemia by day five.
- The clinical utility of complex algorithms and correction formulas for hypocalcemia prediction is limited.

Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.
Calcitonin, a vital polypeptide hormone, regulates calcium levels within body fluids. It is released by the parafollicular cells, also known as C cells, situated in the follicular epithelium of the thyroid gland. Calcitonin responds to fluctuations in blood calcium levels and the influence of gastrointestinal hormones like gastrin and cholecystokinin.
The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
