A significantly greater rise in carboxyhaemoglobin concentration in response to smoking a single cigarette was shown in pregnant (3-9% increase) as opposed to non-pregnant (2-1% increase) women. This was more pronounced when anaemia was present (5-0% increase) and appeared to be inversely related to the haemoglobin concentration. We suggest that the risks to the fetus may be particularly increased when anaemia complicates pregnancy in women who smoke cigarettes.
与非孕妇(升高2-1%)相比,孕妇吸一支烟后碳氧血红蛋白浓度显著升高(升高3-9%)。当存在贫血时,这种情况更明显(升高5-0%),且似乎与血红蛋白浓度呈负相关。我们认为,对于吸烟且贫血并发妊娠的女性,其胎儿面临的风险可能会特别增加。
