研究发现,新生儿在进行体外膜充氧(ECMO)期间脾的体积显著增大。在ECMO开始后的24～48小时内牌开始增大,并呈进行性。虽然这些患儿都是因呼吸衰竭而进行ECMO的,但脾肿大很可能与ECMO治疗有关,而不是与原来的肺部疾病有关。通常使用计算脾体积的公式假设脾是一个扁长的椭圆形。即:脾体积(cm~3)=长×厚×最宽径×0.523。
The study found that neonates had significantly increased spleen volume during extracorporeal membrane oxygenation (ECMO). Within 24-48 hours after the start of ECMO the cards started to increase and were progressive. Although these children are all ECMO due to respiratory failure, splenomegaly may be related to ECMO treatment rather than to the original lung disease. The usual formula for calculating spleen volume assumes that the spleen is a flat oval. Namely: spleen volume (cm ~ 3) = length × thickness × the widest diameter × 0.523.
