RESUMO
OBJECTIVE: To investigate whether perioperative calcium and 1,25 OH vitamin D supplementation (PCDS) influences the rates of postoperative hypocalcemia and length of stay (LOS) following pediatric thyroidectomy. STUDY DESIGN: Retrospective Cohort Review. SETTING: Tertiary children's hospital. METHODS: 94 patients who underwent completion or total thyroidectomy with or without concomitant neck dissection from 2010 to 2020 at a single institution were included. Patients with pre-existing hypocalcemia or preoperative vitamin D insufficiency were excluded. Rates of postoperative hypocalcemia and LOS were compared for patients receiving PCDS to those receiving no supplementation. RESULTS: Thirty percent of patients with PCDS had documented postoperative hypocalcemia compared to 64% of patients without PCDS (p = 0.01). Patients with PCDS had a median LOS of 30 h compared to 36 h (p = 0.002). Multivariable analyses confirmed that patients with PCDS had lower odds of postoperative hypocalcemia (OR: 0.32, CI: 0.11, 0.89) and shorter LOS by 17 h (SE: 8, p = 0.04) after adjustment for confounders. CONCLUSION: PCDS is associated with significantly lower risk of hypocalcemia and shorter LOS. Standardizing preoperative care for pediatric patients undergoing thyroidectomy may decrease variability and improve outcomes following surgery.
