概括
经历出现妄想的老年手术患者显示神经丝光链的增加更高,这是轴突损伤的标志物. 手术后妄与神经丝光链和状纤维酸性蛋白质的增加有关,这表明轴突损伤和天体细胞激活.
科学领域:
- 神经科学是一个神经科学.
- 老年医学 老年医学
- 麻醉学 麻醉学
背景情况:
- 神经炎症和神经元损伤与术后痴呆症 (POD) 的发展有关.
- 像神经纤维光链 (NfL) 和状纤维酸蛋白 (GFAP) 这样的生物标志物可能表明神经元受损.
- 对于老年手术患者来说,了解这些生物标志物在妄想中的作用至关重要.
研究的目的:
- 调查血NfL和GFAP水平与老年手术患者出现突发 Delirium (ED) 和POD的发生之间的相关性.
- 确定潜在的生物标志物,以预测和理解这种脆弱人群中的妄想亚型.
主要方法:
- 患者被分为ED (n=30),POD (n=32) 和匹配的对照组.
- 痴呆症的评估使用了ICU或标准CAM尺度的混乱评估方法.
- 在手术前和手术后使用单分子阵列技术测量了血NfL和GFAP水平.
主要成果:
- 与对照组相比,在ED患者中观察到血NfL的增加 (P=0.002).
- 患有POD的患者表现出血NfL (P<0.001) 和GFAP (P=0.008) 水平的显著增加.
- 多变量分析证实NfL增加与ED相关 (aOR=1.872) 和GFAP增加与POD相关 (aOR=1.419).
结论:
- 老年外科手术患者的突发狂妄与神经丝光链的增加有关,这表明轴突损伤.
- 手术后妄与手术期间的轴突损伤 (NfL) 和天体细胞激活 (GFAP) 相关.
- 这些发现凸显了NfL和GFAP作为不同类型老年痴呆症生物标志物的潜力.

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

Cardiomyopathy VII: Pre and Post Operative Nursing Management
16
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...
