概括

在急性A型大动脉剖析中,体外膜氧化 (ECMO) 的结果不佳. 在此次修复后,心血管气球 (IABP) 可能有助于某些患者从心脏性休克中恢复.

科学领域:

心血管外科
胸部手术
大动脉手术

背景情况:

甲动脉急性解剖是一种危及生命的疾病, 需要进行手术.
在复杂的病例中,可能需要手术内循环支持,包括体外膜氧化 (ECMO) 和大动脉内气球 (IABP).
评估这些支持方法的安全性和有效性对于改善患者的结果至关重要.

研究的目的:

在急性A型大动脉解剖修复过程中评估术内ECMO和IABP的安全性和可行性.
确定这些循环支持策略对住院死亡率和并发症的影响.

主要方法:

在1999年12月至2020年12月期间接受急性甲动脉剖析修复的690名患者的回顾性评估.
鉴定了31名接受了手术期间ECMO或IABP支持的患者,以促进心肺绕道的断奶.
对患者人口统计,手术前情况,手术细节和住院结果的分析.

主要成果:

在接受支持的31名患者中,有11名ECMO患者和20名IABP患者. 平均年龄为65岁,女性占45%.
之前存在的疾病包括冠状动脉逆流 (42%),内脏逆流 (23%),急性冠状动脉综合征 (13%) 和需要心肺复苏 (26%).
整体住院死亡率为67%. ECMO组的死亡率为91%,而IABP组的死亡率为55%. 没有观察到IABP特有的大动脉并发症.

结论:

在急性A型大动脉解剖中,术内ECMO支持与令人丧的高死亡率有关.
在A型急性大动脉解剖修复后的选定患者中,IABP可能具有有益作用,有助于心脏性休克的恢复.
需要对患者选择和最佳使用IABP进行进一步的研究.

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...

Aneurysm III: Interprofessional Care

Aneurysm III: Interprofessional Care

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 III: Medical Management

Aortic Regurgitation III: Medical Management

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...
