NICOTINE, A DANGER FOR NOURISSON?


A new study, published in the " Journal of Physiology Shows that the use of nicotine substitutes (electronic cigarette, patch or lozenge) could increase the risk of sudden infant death, especially in women with serotonin deficiency (or 5-HT).

The study, conducted in rats, reveals that the exposure of baby rats to nicotine impairs their respiratory capacity, especially when they have a serotonin deficiency. The authors of the study suggest that maternal exposure to nicotine places infants with other vulnerabilities, such as mild 5-HT deficiency, at high risk of severe hypoxia, anoxia and asphyxia. »

Recall that the use of nicotine replacement is allowed during pregnancy, under the supervision of the doctor, and remains - for now - an interesting alternative to help pregnant women to wean themselves off the cigarette. It is known that the harmful substances contained in a cigarette, including nicotine, cross the placental barrier and cause a reduction in the oxygen supply to the child. The smoke also causes an acceleration of the heartbeat and elevation of blood pressure.
