Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...

Cardiomyopathy VII: Pre and Post Operative Nursing Management

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...

Aneurysm IV: Nursing Management

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...

科学领域:

  • 肝病学 肝病学是一种肝病学.
  • 手术瘤学手术瘤学
  • 关键护理医学 关键护理医学

背景情况:

  • 肝硬化增加了术后死亡风险,部分原因是门性高血压.
  • 在手术前进行的横性肝脏内移植系统分流器 (TIPS) 放置可能会减轻手术风险.
  • 之前关于手术前TIPS益处的研究受到了混和缺乏纵向数据的限制.

研究的目的:

  • 评估手术前TIPS安置与肝硬化患者手术后死亡率之间的关联.
  • 分析TIPS在重大手术前对纵向肝功能标志物的影响.

主要方法:

  • 使用退伍军人卫生管理局数据 (2008-2022) 的回顾性队列研究.
  • 在手术前6个月内,确定了经历重大手术和TIPS安置的肝硬化患者.
  • 倾向性得分匹配 (5:1) 用于比较TIPS和非TIPS组之间的结果,包括人口统计数据,并发症,手术类型和实验室数据.

主要成果:

  • 倾向匹配的队列包括39名手术前TIPS患者和171名没有.
  • 考克斯回归显示,手术前的TIPS与术后死亡率的增加有关 (HR: 2.69).
  • 与非TIPS患者相比,TIPS患者在手术前立即表现出肝脏合成功能恶化 (白蛋白降低,胆红素和INR升高) .

结论:

  • 最近的手术前TIPS安置与经历重大手术的肝硬化患者的术后死亡率增加有关.
  • TIPS安置会在手术前期对肝脏合成功能产生负面影响.
  • 对于面临重大手术的肝硬化患者来说,仔细考虑手术前的TIPS至关重要.
