我妈妈在中国得了尿路感染，她已经超过７０岁了，可能是老年性的尿路感染。医生让她静脉输盐酸左氧氟沙星氯化钠注射液一周。第一天我妈妈中午１２点输完，回到家以后大约在下午２到３点左右我妈妈就开始感到全身发冷，全身无力，非常不舒服，盖上大被后症状２到３个小时才消失。她已经输了３天了，都是在下午２到３点左右，发生同样的症状，但昨天症状稍轻一些。有谁知道这是什么问题，她还能继续静脉输这个药吗？

是由于药物或液体的质量问题

产品的纯度/消毒不够, 残留的致热原会引起输液反应.

I think you are right about it. "Infusion reaction" occurs so often in China and a doctor can see it every day mainly because of pyrogens have not been get rid off. It is really a quality control issue.

Infusion reaction is so rare in USA that a physician can hardly see one.
