概括
术前输血,而不是症状到手术的时间,在急性A型大动脉解剖 (ATAAD) 患者中显著影响死亡率. 透是ATAAD中手术和中期死亡率的关键预测因素.
科学领域:
- 心血管外科心血管外科
- 胸部外科手术 胸部外科手术
- 大动脉疾病 大动脉疾病
背景情况:
- 急性甲动脉解剖A型 (ATAAD) 是一种危及生命的疾病,需要迅速的手术干预.
- 在ATAAD中进行手术的最佳时间仍然是争论的主题,特别是关于症状至手术持续时间的影响.
- 众所周知,ATAAD的一个并发症 - - 器官的血液流动受到损害的恶性输液 (Malperfusion) 会影响结果.
研究的目的:
- 调查症状到手术时间对ATAAD患者死亡率的影响.
- 为了比较早期 (≤10小时) 和晚期 (>10小时) 手术的患者之间的结果.
- 确定ATAAD患者手术和中期死亡率的关键预测因子,特别是评估 malperfusion 的作用.
主要方法:
- 对288名被诊断患有ATAAD的患者进行了回顾性分析.
- 患者被分为早期 (≤10小时) 和晚期 (>10小时) 的症状至手术时间组.
- 采用多变量逻辑回归来确定死亡风险因素,包括阻 perfusion 状态和特定器官参与.
主要成果:
- 在早期和晚期症状到手术时间组之间没有观察到死亡率的显著差异.
- 年龄,体外膜氧化 (ECMO) 的使用,并存在和程度的 malperfusion 是重要的预测器的手术死亡.
- 缺血,特别是涉及大脑,心脏或四肢动脉,以及多器官缺血,与手术死亡率的增加密切相关. 宾夕法尼亚分类B和BC也预测了死亡率.
- 存活分析显示,与没有 (9%) 患者相比,在接受 malperfusion (34%) 的患者中,死亡率显著更高.
结论:
- 在ATAAD患者中,手术前和中期死亡率的决定因素,比症状到手术的时间更为关键.
- 早期手术干预似乎并不能像治疗手术前输血一样显著地减轻死亡风险.
- 是关键的预测因素,应该指导ATAAD的临床管理和风险分层.

Aneurysm IV: Nursing Management
2
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...

Aneurysm III: Interprofessional Care
2
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Aortic Regurgitation I: Introduction
3
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...

Aortic Regurgitation IV: Nursing Management
12
A nurse managing a patient with aortic regurgitation begins with a comprehensive assessment, including a review of the patient's medical history, family history, and lifestyle factors. During the cardiac examination, the nurse listens for heart sounds and checks for signs of valve abnormalities. The nurse also observes for symptoms such as dyspnea, orthopnea, and paroxysmal nocturnal dyspnea and assesses the patient's endurance and daily activity tolerance.Based on the findings, the nurse...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
