甲状腺术后的甲状腺功能维护

甲状腺功能减退是甲状腺手术最常见的并发症.左甲状腺素钠（L-T4）是治疗甲状腺功能减退的首选药物,甲状腺功能维护可于术后早期进行,L-T4的需要量受多个因素及目标TSH的影响,实施过程中应考虑患者的特殊性（依从性差、妊娠、老年）,并定期（4～6周）复查甲状腺功能,根据目标TSH调整最佳用药剂量,避免治疗不足和治疗过度.T3分次给药或L-T4/T3联合治疗可作为L-T4治疗失败患者的选择.

Thyroid function maintenance following thyroidectomy

Postoperative hypothyroidism is the most common complication following thyroidectomy,and thyroxine replacement is needed to maintain thyroid function.Levothyroxine （L-T4） is the preferred drug for the treatment of hypothyroidism.L-T4 therapy can be initiated immediately after thyroid operation,and the dosages are influenced by target serum TSH and several other factors.Special consideration should be taken for such patients,including patients with poor compliance,during pregnancy,and elderly patients.Thyroid function should be measured every 4 to 6 weeks,optimal dosages are adjusted according to target serum TSH individually,avoiding under-treatment or over-treatment.T3 in divided doses or L-T4/T3 combination therapy can be served as alternative for those failed to L-T4 therapy alone.
