概括
上腺静脉采样 (AVS) 可以在ACTH后5分钟和10分钟更早进行,而不会显著影响解释. 这种优化可能会提高AVS过程中的程序效率和患者舒适度.
科学领域:
- 内分泌学 在内分泌学.
- 干预性放射学 干预性放射学
- 手术创新 在外科创新.
背景情况:
- 上腺皮质激素 (ACTH) 刺激是上腺静脉采样 (AVS) 的标准.
- 目前的指导方针建议在ACTH注射后15-30分钟取样.
- 在技术上,AVS是一个要求很高的过程,可能会持续很长时间.
研究的目的:
- 评估早期ACTH后采样时间 (5分钟和10分钟) 对AVS结果解释的影响.
- 为了比较早期AVS样品的诊断准确性与标准的15分钟样品.
- 探索程序效率和患者安全的潜在改进.
主要方法:
- 连续接受AVS的成年患者的回顾性分析.
- 同时双边上腺静脉采样使用标准化方法.
- 在ACTH后5分钟和10分钟的阿尔多和皮质醇水平与15分钟后的比较.
主要成果:
- 与15分钟样本相比,在5分钟和10分钟样本之间没有观察到侧面化指数 (LI) 或整体侧面化的显著差异.
- 早期AVS样本 (5分钟和10分钟) 与15分钟样本有很强的相关性.
- 在ACTH后的样本中,选择性上腺静脉管通过类固醇增加 (SI) 得到证实.
结论:
- 较早的ACTH后血液采样 (5分钟和10分钟) 是可行的AVS.
- 这种修改可能会提高程序效率并降低风险.

Adrenal Gland Disorders
1.3K
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Hormones of the Adrenal Glands
2.1K
Adrenal hormones play a pivotal role in maintaining the body's electrolyte balance and orchestrating responses to stress, showcasing the intricate functions of the adrenal cortex and medulla.
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and...

Anatomy of the Adrenal Glands
1.8K
The adrenal or supra-renal glands, situated above the kidneys and aligned with the twelfth rib, are paired pyramid-shaped structures crucial for the body's stress response. During stress, these glands secrete hormones vital for adaptive physiological reactions.
These glands possess a distinctive yellow tinge due to the stored cholesterol and fatty acids required for hormone synthesis. They are encased in a fibrous capsule and cushioned by fat.
The adrenal gland comprises two distinct...

Adrenergic Agonists: Therapeutic Uses
700
Adrenergic agonists have diverse therapeutic uses across various medical conditions and emergencies.
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

Hypothalamic-Pituitary Axis
58.7K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.
