- 关键护理医学 关键护理医学
背景情况:
- 中高风险肺栓塞 (PE) 呈现出右心室功能障碍和心脏生物标志物升高,通常用抗凝药治疗.
- 目前的指导方针为血液动力学不稳定的PE患者保留了全身纤维解析.
- 耐火性低氧化症,尽管保持了全身输液,但在正常压力PE中可能表明刚开始的右心室循环崩,这种情况下纤维素溶解的迹象尚不清楚.
研究的目的:
- 评估系统性纤维解酶在患有中高风险肺栓塞的正常血压患者的疗效和安全性,患有耐火性低氧症.
- 探索中等风险PE超出低血压的临床恶化概念,包括孤立的呼吸衰竭.
主要方法:
- 一个案例介绍了75岁的男性在关节镜后修复阴茎,由于广泛的双侧中央PE而导致急性呼吸不良和严重的呼吸衰竭.
- 诊断工作包括实验室测试 (热波宁-I,BNP),心声学 (RV扩张) 和CT肺血管学.
- 治疗涉及阶段性全身纤维素分解与阿尔泰普拉斯由于不可用导管治疗和患者转移风险,暂时停止肝素.
主要成果:
- 患者出现了严重的呼吸衰竭,右心室扩张和广泛的PE,尽管胸部X射线图正常.
- 系统性纤维解析导致氧化和右心室指数的迅速改善.
- 患者在第二天被抽管,在第7天从重症监护室出院,并在3个月后仍然无症状,心声回声正常,没有出血或手术并发症.
结论:
- 在正常压力中等高风险PE中,除了对酶体肺病外,耐药性低氧症可能代表早期的循环失补偿,这证明了再输血的合理性.

274
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...

01:29Pulmonary Embolism I: Introduction
459
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

315
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...

01:29Venous Thrombosis III: Interprofessional Care
257
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...

01:21Acute Respiratory Failure-II
980
Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:

01:30Venous Thrombosis I: Introduction
267
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
