Extracorporeal membrane oxygenation (ECMO), originally developed as an artificial replacement for respiratory assistance, is decreasingly used in neonates with respiratory failure. Nevertheless, there is a constant need for this invasive and expensive neonatal treatment modality.
Review of our experience (80 recent ECMO performances because of circulatory failure) and the literature.
In contrary to reduced ECMO performances out of respiratory insufficiency in neonates, ECMO as circulatory support is increasingly used. Neonatal sepsis, pre- and postoperative cardiac failure, combined circulatory and respiratory failure after resuscitation and with congenital diaphragmatic hernia result in a permanent need for ECMO, whenever there are fewer ECMO treatments per year. Nonocclusive pumps, portable devices, small priming volumes and tapered anticoagulation protocols enable survival through ECMO even in virtually hopeless hemodynamic conditions. Special efforts in investigation and prevention of permanent neurological impairment, especially after severe pre-ECMO hypoxia seem to be mandatory.
ECMO remains an important tool in neonatal and pediatric intensive care. However, the number of ECMO therapies was reduced due to respiratory therapeutic progress, but indications and ECMO technology have changed.
体外膜肺氧合(ECMO)最初是作为呼吸辅助的人工替代手段而开发的,目前在呼吸衰竭新生儿中的应用越来越少。然而,对于这种侵入性且昂贵的新生儿治疗方式仍有持续需求。
回顾我们的经验(近期因循环衰竭进行的80例ECMO治疗)及相关文献。
与新生儿呼吸功能不全时ECMO应用减少的情况相反,ECMO作为循环支持手段的应用越来越多。新生儿败血症、术前和术后心力衰竭、复苏后以及先天性膈疝合并循环和呼吸衰竭,无论每年ECMO治疗次数多少,都会导致对ECMO的持续需求。非阻塞性泵、便携式设备、小预充量和逐步抗凝方案即使在几乎绝望的血流动力学条件下也能使患儿通过ECMO存活。在调查和预防永久性神经损伤方面做出特别努力似乎是必要的,尤其是在ECMO前严重缺氧之后。
ECMO仍然是新生儿和儿科重症监护中的重要工具。然而,由于呼吸治疗的进展,ECMO治疗的数量有所减少,但适应症和ECMO技术已经发生了变化。
