背景资料：在接受体外膜肺氧合（ECMO）治疗的急性重度呼吸衰竭（ARF）患者中，放射学评价迄今几乎完全依赖于床旁X线摄影和US。在圣戈兰/卡罗林斯卡ECMO中心，CT已成为床边检查的常规补充。目的：回顾性分析ARF患者在ECMO上的频率、适应症和CT结果，并评估与CT检查相关的运输并发症风险。材料和方法：1994年5月至2001年1月，112例新生儿、儿童和成人接受ECMO治疗。其中46%的患者在ECMO期间进行了一次或多次CT检查，共计104次检查238个部位。所有CT检查均在儿科放射科进行，包括使用移动的ECMO系统进行10分钟转运。结果：老年患者和ECMO运行时间较长的患者更常进行CT检查。主要适应症为ECMO疑似并发症和/或基础疾病或临床改善延迟。在57%的CT检查中，发现了影响治疗的重大发现。没有与检查或运输相关的并发症。结论：CT是评价ECMO中ARF患者安全有效的方法。
Background: In patients with acute severe respiratory failure (ARF) treated with extracorporeal membrane oxygenation (ECMO) the radiological evaluation has until now almost exclusively relied on bedside radiography and US. At St. Goran/Karolinska ECMO centre CT has become a routine complement to bedside examinations. Objective: To review retrospectively the frequency, indications and findings on CT of patients with ARF on ECMO and to evaluate the risk of complications associated with transportation for CT examinations. Materials and methods: One hundred twelve neonates, children and adults were treated with ECMO from May 1994 to January 2001. Forty-six per cent of these patients had CT examinations on one or more occasions during ECMO, giving a total number of 238 examination sites on 104 occasions. All CT examinations were performed in the Paediatric Radiology Department and included a 10-min transport using a mobile ECMO system. Results: CT was more often performed in older patients and in patients with long ECMO runs. The main indications were suspected complications of ECMO and/or the underlying disease or a delay in clinical improvement. In 57% of the CT occasions, significant findings affecting treatment were revealed. There were no complications associated with the examinations or transport. Conclusions: CT is safe and useful in evaluation of patients with ARF during ECMO.
