    Abstract:
    In prenatal life the fetus can be exposed to more incentires which affect the mother. In case of both active and passive smoking by pregnant women many pernicious substances contained in tobacco smoke can influence the foetus. The components of tobacco smoke can contribute to various antenatal complications. The aim of present work was to assess if the data given by the patient in anonymous questionnaire go along with the real exposure to components of smoke assessed on the basis of concentration of nicotine metabolite- cotinine in mother's serum and next to assess the risk of development of gestational hypertension and hypotrophy. The biological material was extracted with means of liquid-liquid technique and next we performed laboratory determinations with means of liquid chro- matography with sectrophotometric detection, in which norephedrine is used as inner sample. The study was carried out on 106 women in perinatal period who give birth from single, full term pregnancy. On the basis of questionnaire data considering the concentration of cotinine, the patients were divided into three groups: I group--active smokers (n = 27), II group--passive smokers (n = 32), III group--not exposed to tobacco smoke (n = 41). The average concentration of cotinine in blood serum in the first group was 129.6 ng/ml, second group--5.1 ng/ ml, but in all patients from the control group the concentration of cotinine was below the detection level. Gestational hypertension was diagnosed in 17 women (16%) and hypotrophy of the foetus was diagnosed in 15 patients (14%). Tobacco smoking didn't influence the development of gestational hypertension and hypotrophy showered it is more often observed in women exposed to components of tobacco smoke during pregnancy.
