PTH and Hypocalcemia: Therefore, monitoring serial calcium and parathyroid hormone (PTH) levels in the immediate postoperative period is recommended.3 This use of perioperative PTH monitoring may decrease morbidity and allow for stratification of patients who would benefit from more intensive monitoring and treatment with calcium and calcitriol.3,6 Despite these recommendations, there is an overall lack of consensus on an ideal prophylactic regimen in pediatric patients leading to variability in the postoperative management of hypocalcemia.
