概括
连续静脉血液过 (CVVHDF) 并不能去除甲状腺激素. 在CVVHDF的ICU患者中,甲状腺激素水平的变化是由于降低了神酶活性,而不是激素损失.
科学领域:
- 关键护理医学 关键护理医学
- 内分泌学 在内分泌学.
- 腎臟病學 (nephrology) 是一種醫學專業.
背景情况:
- 非甲状腺疾病综合征在重症监护室 (ICU) 患者中很常见.
- 连续静脉血液过 (CVVHDF) 可能会因为甲状腺激素的小分子大小而去除甲状腺激素.
- 在CVVHDF期间评估甲状腺激素水平对于了解患者的新陈代谢至关重要.
研究的目的:
- 为了确定血清甲状腺激素度在CVVHDF期间是否发生变化.
- 研究CVVHDF在甲状腺激素去除中的作用.
- 在接受CVVHDF的重症患者中确定甲状腺功能障碍的潜在机制.
主要方法:
- 一项前性观察性试验,涉及30名急性损伤 (AKI) 的ICU患者,需要CVVHDF.
- 血液样本采集在CVVHDF前,在治疗期间的多个时间点,以及治疗后.
- 测量TSH,TRH,FT3,FT4,TT3,TT4,RT3,并计算周围神酶活性 (GD).
主要成果:
- 甲状腺刺激激素 (TSH) 和甲状腺激素释放激素 (TRH) 水平在很大程度上保持正常.
- 自由甲状腺素 (fT4) 和总甲状腺素 (tT4) 是正常的或略低;自由三甲状腺素 (fT3) 和总三甲状腺素 (tT3) 大多是无法检测的.
- 在CVVHDF期间没有观察到甲状腺激素水平的显著变化;外围神酶活性 (GD) 低但稳定.
- 反向三甲氨酸 (rT3) 水平保持在正常范围内.
结论:
- CVVHDF不会导致甲状腺激素的显著损失.
- 在接受CVVHDF的患者中,降低的外周二氧化酶活性,而不是血液过,是导致甲状腺激素度变化的原因.
- 这一发现澄清了AKI和CVVHDF重症患者的代谢变化.

Continuous Renal Replacement Therapy
143
Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

Hemodialysis III: Nursing Management
187
The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this...

Hemodialysis II: Procedure and Complications
131
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Functions of Thyroid Hormones
3.2K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Hemodialysis I: Introduction
290
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early. Patient intake and output are...
