The maternal and fetal effects of smoking tobacco or non-tobacco cigarettes were studied in 75 pregnant patients and compared with a matched control group of 22 pregnant patients who did not smoke. The increase in maternal heart rate, maternal mean arterial pressure and fetal heart rate, and decrease in fetal heart rate 'baseline variability' and in fetal movements, were shown to be due primarily to the nicotine content of the cigarette.
对75名孕妇吸烟或吸非烟草香烟的母婴影响进行了研究，并与22名不吸烟的配对孕妇对照组进行了比较。结果显示，孕妇心率、孕妇平均动脉压和胎儿心率的增加，以及胎儿心率“基线变异性”和胎动的减少，主要是由于香烟中的尼古丁含量所致。
