以副甲状腺激素 (PTH) 水平为指导的选择性补充剂在预防全甲状腺切除术后的低血症方面并不优于常规的预防性和 (C+C). 这两种策略都是可行的,取决于临床环境和资源.
科学领域:
- 内分泌学 在内分泌学.
- 手术并发症 手术并发症
- 临床试验 临床试验
背景情况:
- 手术后的低血是完全甲状腺切除术后的一个常见并发症.
- 常规预防性和醇 (C+C) 补充剂是标准的,但可能导致过度治疗.
- 基于早期术后副甲状腺激素 (PTH) 水平的选择性补充是一种替代方法.
研究的目的:
- 为了比较常规预防性C + C和选择性PTH导向补充剂之间的症状和生化低血症的发生率.
- 评估选择性补充剂在减少全甲状腺切除术后过度治疗的有效性.
主要方法:
- 一个多中心的实用性随机临床试验,涉及258名接受全甲状腺切除术的成年患者.
- 干预措施包括15天的常规预防性C + C,以及以4小时的术后PTH水平 (<15 pg/mL) 为指导的选择性补充.
- 主要结局是15天的症状性低血症;次要结局包括生化低血症和不良事件.
主要成果:
- 症状性低血症发生在PTH组的7.8%,C+C组的11.1% (OR,0.68;P=.36).
- 在PTH组的21.6%和C+C组的17.6%观察到生化低血症 (OR,1.29;P=.53).
- 副作用是相似的;PTH组需要更少的补充剂.
结论:
- 基于术后PTH水平的选择性补充剂在预防全甲状腺切除术后的低血症方面并不优于常规的预防性C+C.
- 这两种策略都是有效的,选择可能取决于资源的可用性和临床背景.
- 进一步的研究可能会探索每个策略的成本效益和患者报告的结果.
