Impact of Expired Carbon Monoxide Measurement on Smoking Cessation of Pregnant Women
- Conditions
- Smoking Cessation
- Registration Number
- NCT03842449
- Lead Sponsor
- University Hospital, Limoges
- Brief Summary
France is the country of Europe where the prevalence of pregnant women smokers is the highest (35.9% before pregnancy and in the 3rd quarter 21.8% in 2008).
In the investigator's country, among the smokers of early pregnancy with the usual care, only 30% manage to stop during pregnancy.
Maternal smoking during pregnancy is a clearly identified risk factor for the course of pregnancy and the unborn child.
The measurement of carbon monoxide (CO) expired in pregnancy monitoring consultation is part of the recommendations of the consensus conference "Pregnancy and Tobacco" (ANAES, October 2004) and the parliamentary report on smoking by JL Touraine and D. Jacquat (Feb 2012). However, this recommendation has not entered the current practice. The research aims to justify the clinical relevance of this recommendation by demonstrating the positive impact of expired CO measurement on the rate of discontinuation during pregnancy.
