Conséquences fœtales du tabagisme sur les modes d'accouchement, l'hypoxie et l'acidose per-partum

Data in the literature is not sufficient to argue in favor of an association between fetal asphyxia during labor and smoking. Only one study showed a higher rate of cesarean section in mothers smoking more than 10 cigarettes per day. Nevertheless, the Apgar score does not appear to be modified by moderate maternal smoking. Paradoxically, maternal smoking could have a protective effect on meconial aspiration and could have a moderately reducing effect on the rate of cesarean section during labor in patients smoking less than 10 cigarettes per day via lower fetal weight. These findings should be examined with caution because they still need to be confirmed and do not take into consideration other adverse effects of smoking on the fetus.
