概括
在儿科心脏外科手术中,脉动性心肺绕道并没有显著改善大脑血液动力学或临床结果,而非脉动性绕道相比,尽管有更强的生理脉动性指数.
科学领域:
- 心脏病学 心脏病学
- 儿科手术 儿科手术
- 生物医学工程 生物医学工程
背景情况:
- 遗传性心脏病 (CHD) 需要复杂的手术干预.
- 心肺绕道 (CPB) 是心脏手术的一个关键组成部分.
- 在CPB期间输血方式可能会影响患者的治疗结果.
研究的目的:
- 评估脉动性与非脉动性CPB对大脑血液动力学的影响.
- 评估儿科患者的临床结果,这些儿科患者患有先天性心脏病的青色和蓝色心脏病,接受CPB.
- 确定CPB模式是否影响器官损伤和死亡率.
主要方法:
- 159名患有心脏病的儿科患者 (<18岁) 被随机分配到脉动性或非脉动性CPB.
- 患者被分为两层,分为青色和蓝色的小组.
- 测量了大脑气体微栓塞,中脑动脉脉动指数和器官损伤得分 (PELOD-2).
主要成果:
- 脉动性CPB导致了在乙烯酸和酸组中的更高的脉动性指数.
- 在 perfusion 模式之间,脑氧化,微栓塞或器官损伤得分没有显著差异.

Cardiac Catheterization I: Pre-Procedure Overview
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...
Cardiac Catheterization II: Right Heart Catheterization
Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
Cardiac Catheterization III: Left Heart Catheterization
Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...
