RESULTS There were no complications relating to ECC in all of the 240 infants.The ECC time ranged from 49 min to 184 min and the aorta cross-clamp time ranged from 17 min to 110 min.The ultrafiltration volume ranged from 150 ml to 400 ml. The intraoperative Hct ranged from 16% to 20% and the hematocrit after MUF ranged from 30% to 39%.The mechanical ventilation support time after operation ranged from 6 h to 72 h.

结果 240例患儿未发现同ECC有关的并发症，ECC时间为49～184 min、升主动脉阻断时间17～110 min，改良超滤滤出液体150～400 ml，全组患者术中Hct维持0.16～0.20，改良超滤结束Hct为0.30～0.39，术后呼吸机辅助时间6～72 h，24 h胸腔引流量30～110ml，术后输入库血量100～200 ml。

CUF is not the effective method to increase the COP during ECC, actually, MUF can effectively promote the COP after ECC in infants undergoing ECC heart surgery.

CUF可以提高ECC期间的COP，但效果不够理想；MUF是提高术后COP的有效手段。

Using bubble oxygenator, ECC time more than 180minutes , pressure before the artery filter higher than 240 mmHg and haematocrit in the first blood gas analysis more than 27% were significantly different.

ECC血红蛋白尿的产生是一种较为常见的并发症，它与ECC用品，ECC时间，患者自身状态等多种因素有关。

METHODS 30 patients undergoing ECC surgery were randomly divided into two groups. 14 patients in CO2 group were insufflated with CO2 at pericardial cavity via a new designed gas-diffuser during ECC, whereas 16 patients in control group were not.

30例ECC手术病例随机分为二氧化碳组与对照组，前者使用改进后的气体弥散器在ECC期间向术野充弥二氧化碳，后者不进行此项干预。

When the data and ECC are read, the function is recomputed, the result is compared to the ECC appended to the data, and correction is performed if necessary.

当读取数据与ECC码时，再使用ECC码的计算函数进行计算，并将得到的结果与ECC码进行比较，如果可能的话更正发现的错误。
