背景情况:

儿童心脏外科手术通常需要心肺绕道 (CPB).
静脉动脉外体膜氧化 (V-A ECMO) 用于重症儿科患者的血液动力学支持.
从V-A ECMO过渡到CPB通常涉及一个单独的电路,增加复杂性和资源利用.

研究的目的:

在儿科患者中描述两种用于将V-A ECMO电路直接转换为CPB电路的新策略.
评估心脏手术期间这种综合方法的可行性和安全性.

主要方法:

修改现有的V-A ECMO电路,以整合必要的CPB组件.
在ECMO配置中整合静脉水库,心肌 delivery,超过和心脏切割吸入.
使用修改后的ECMO电路作为唯一的CPB系统执行所有必要的心脏外科手术程序.

主要成果:

通过使用描述的策略,成功将V-A ECMO转换为功能CPB电路.
修改后的电路使心脏外科手术的各个方面都更容易完成,而不需要单独的CPB机器.
患者没有表现出明显的术后凝血病.
在术后期间没有观察到的神经功能障碍.

结论:

描述的新策略为在V-A ECMO支持下进行儿科心脏手术提供了一种简化方法.
这种综合方法最大限度地减少了电路表面积的暴露,并减少了对血液制品的需求.
这种技术似乎是安全有效的,避免了像凝血病和神经功能障碍等重大并发症.

Mechanical Ventilation III: Noninvasive Ventilation

Mechanical Ventilation III: Noninvasive Ventilation

Noninvasive positive-pressure ventilation (NIPPV), continuous positive airway pressure (CPAP), and bilevel positive airway pressure (BiPAP) are essential methods in respiratory care. These ventilation techniques offer unique benefits for patients with various respiratory conditions, providing adequate support without requiring intubation. Let's explore how each method is crucial in improving patient outcomes and enhancing respiratory therapy.

Mechanical Ventilation II: Invasive Ventilation

Mechanical Ventilation II: Invasive Ventilation

Ventilators are essential medical equipment used to aid patients with respiratory difficulties. Their primary function is to assist or replace spontaneous breathing by providing mechanical ventilation. There are two general classes of mechanical ventilators: negative-pressure and positive-pressure ventilators.
Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...

Mechanical Ventilation I: Indication and Settings

Mechanical Ventilation I: Indication and Settings

Mechanical ventilation is a life-saving technique for managing acute respiratory failure and other respiratory complications. The process involves using a machine known as a ventilator to supply oxygen to the lungs and assist in removing carbon dioxide. It serves as a bridge to long-term mechanical ventilation or a temporary measure until ventilatory support is discontinued. The ventilator can maintain this function for a prolonged period, providing critical support for patients until they can...
