NEW ORLEANS -- Nicotine patches may help highly addicted but highly motivated pregnant women quit smoking, according to results of a study presented at the annual meeting of the Society for Maternal-Fetal Medicine.
Of 21 women who used the patch during an 8-week period in the third trimester, 8 stopped smoking through the time of birth, and 4 continued to refrain from smoking 4 weeks after delivery. Two women remained abstinent 1 year later, Dr. Paul L. Ogburn Jr. reported.

The study began with a 4-day inpatient stay. The women received nicotine patch therapy, 22 mg per 24 hours, for a total of 8 weeks. Serial ultrasound examinations and weekly nonstress tests documented fetal growth and well-being throughout the study. The women also were evaluated biochemically from enrollment through delivery using measurements of exhaled carbon monoxide, said Dr. Ogburn, director of the division of maternal-fetal medicine at the State University of New York at Stony Brook.
Gestational ages at delivery ranged from 36.3 to 41.1 weeks (median 39.1). Neonatal weights ranged from 2,400-4,400 g (median 3,405 g). None of the neonates were below the 10th percentile for weight.
