概括
高剂量的抗血素III并没有改善严重败血症患者的存活率. 然而,它在未接受肝素的小组中显示出潜在的生存益处,但在与肝素一起使用时会增加出血风险.
科学领域:
- 临界护理医学 临界护理医学
- 血液学 血液学 血液学
- 药理学 药理学是指药理学的学科.
背景情况:
- 严重的败血症和败血性休克会激活凝血,导致微血栓,器官功能障碍和死亡.
- 抗血素III (AT III) 是一种内源性抗凝剂,可以在危急疾病中提供保护.
研究的目的:
- 评估高剂量抗血素III在改善严重败血症或败血性休克患者的存活率方面的疗效.
主要方法:
- 一个多中心,双盲,安慰剂控制的第三期试验 (KyberSept) 随机选择了2314名成年患者.
- 患者接受了静脉注射的抗血素III (30,000 IU超过4天) 或安慰剂.
- 主要结局是28天全因死亡率.
主要成果:
- 在AT III和安慰剂组之间,28天的总死亡率相似 (38.9%与38.7%,P=.94).
- 二次终点如ICU存活率没有显著差异.
- 在没有接受氨酸治疗的患者中,AT III显示出28天死亡率降低的趋势 (P=.08) 和显著的90天生存益处 (P=.03).
- 与AT III同时使用肝素显著增加出血风险 (23.8%对13.5%,P<.001).
结论:
- 在败血症发作后6小时内服用高剂量的抗血素III不会改善28天的存活率.
- 与肝素相结合的AT III增加了出血风险.
- 在没有同时治疗肝素的败血症患者中,AT III可能存在潜在的生存益处.

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Venous Thrombosis III: Interprofessional Care
482
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care
749
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Pulmonary Embolism III: Nursing Management

A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...
