Abstract
This study was designed to evaluate the acute effects of smoking cigarettes on uterine contractility and on fetal heart rate. The present study was carried out at Aim Shams University, in the period from 1st, March, 2009 to the 1st, March 2010. It included 120 pregnant women in their third trimester. They divided into two groups according to their habit of smoking: The first group (the study group; Group A): included 60 pregnant females in their third trimester who were smoking any type (smoking cigarette, cigar, pipe, or shisha). The second group (the control group; Group B): included 60 pregnant females in their third trimester who were not exposed to smoking. The purpose of the study was explained to all participants and an informed consent to participate in the study was taken. All included cases were submitted to the following: Full history taking, full clinical examination, and all participants completed a questionnaire containing demographic data, course of current pregnancy, and smoking habit The CTG after smoking 1 cigarette provided that she did not smoke for the past 12 hours for group A to evaluate uterine contraction, fetal heart rate and fetal movement
Results: smoking women had increased heart rate, systolic and diastolic blood pressure when compared to non smokers. In addition, maternal heart rate, systolic and diastolic blood pressure was increased after smoking one cigarette in comparison to their values before it. Furthermore, uterine contractility was decreased in smokers in comparison to non smokers, and after smoking one cigarette in comparison to their values before it. Fetal heart rate was increased and fetal movements and acceleration were decreased in smokers’ women in comparison to non smokers. Also, after smoking one cigarette in comparison to their values before smoking it.
Conclusion: the results of the present study proved that there were adverse effects of chronic or acute cigarette smoking on maternal and fetal hemodynamics
