Overview
Hypocalcemia is defined as having a low calcium concentration in blood.The normal range of serum calcium lies between 8.8–10.7 mg/dl or 4.3–5.2 mEq/l. In the past 20 years quantification of serum and ionized calcium and PTH concentrations has helped in easier diagnosis. It is difficult to quantify the incidence of ionized hypocalcemia.
Epidemiology and Demographics
Incidence
- The incidence of hypocalcemia is inversely proportional to gestational age and birth weight.[1][2]
- The percentage of infants who develop hypocalcemia is between 30% to 90%.
- The incidence of hypocalcemia in postsurgical patients is between 80 to 90%.
- The incidence of hypocalcemia after thyroidectomy is 27%.[3][4][5][6]
Mortality rate
- The mortality rate of hypocalcemia is approximately 44% in acutely ill patients in a medical intensive care setting.[7][8]
- Hypocalcemia has been reported in critically ill patients, most commonly in association with sepsis syndrome.[9]
