“…In this study, we measured fetal heart rate after overnight abstinence and again approximately 2.5 hours later after continued smoking or use of nicotine replacement therapy when significant effects of smoking or nicotine would be expected to occur [23][24][25][26]. We did not find a significant reduction in overall daily fetal heart rate among groups as we did with maternal heart rate.…”

Objective-To examine the short-term effects of the nicotine patch or nasal spray on measures of nicotine exposure, withdrawal symptoms, and on maternal and fetal heart rates in pregnant smokers.Methods-We measured nicotine/cotinine concentrations and maternal and fetal heart rates during an 8-hour monitoring session while smoking and again after 4 days of nicotine patch (15 mg/16 hours), nasal spray (recommended regimen of 24 doses per day), or placebo treatment. Nicotine withdrawal symptoms were assessed daily.Results-Twenty-one subjects, who smoked an average of 17 cigarettes per day, completed both monitoring sessions. Nicotine concentrations decreased from baseline smoking concentrations in all groups (p = 0.002). Percent change in cotinine concentration differed across groups (reduction = 77% with placebo, 70% with nasal spray, and 48% with patch; p = 0.029). Maternal heart rate decreased in the placebo and nasal spray groups compared with the patch group (p = 0.021). The baseline fetal heart rate decreased in the placebo group throughout the second monitoring session, but increased slightly in the patch and nasal spray groups. The treatment by time interaction was marginally significant (p = 0.052). Daily cigarette craving decreased more in the patch versus the other groups (p = 0.025).Conclusions-Nicotine patch and nasal spray reduce maternal nicotine exposure compared with smoking and may be effective for smoking cessation.

“…Smoking during pregnancy has been linked to various adverse outcomes, and the pathophysiological mechanism suggested includes reduced uteroplacental blood flow and fetal hypoxia, which explain the decrease in FM (40 found the same association between DFM and an increased risk of birthweight <2500 g or birth of SGA infants (33).…”

Objective. ‘Normal’ fetal activity is recognized as a sign of fetal well‐being and concerns for decreased fetal movements is a frequent cause of non‐scheduled antenatal visits. The aim of this study was to identify maternal characteristics in women presenting decreased fetal movements in a total population, to identify the risk of adverse outcomes and assess the management provided. Design. Prospective population‐based cohort. Setting. Fourteen delivery units in Norway. Population. A total of 2,374 pregnancies presenting with a perception of decreased fetal movements and 614 control/referent cases. Methods. All singleton third trimester pregnancies presenting with a perception of decreased fetal movements were registered from June 2004 through October 2005. Pregnancies never examined for this condition were collected as a cross‐sectional sample from the same population. Main outcome measures. Fetal growth restriction, preterm birth and stillbirth. Results. Mothers with decreased fetal movements were more often smokers, overweight and primiparous. Of the women, 32% presented with perceived absence of fetal movements, of whom 25% waited for more than 24 hours without any movements. Abnormal findings were identified in 16% of examinations. Decreased fetal movements were associated with adverse pregnancy outcome in 26%, including preterm birth and fetal growth restriction. An intervention or repeated consultations were performed in 41% of cases, including 14% admissions to maternity ward. None of the included hospitals had written guidelines for management. Conclusions. A perception of decreased fetal movements is significantly associated with adverse pregnancy outcome such as preterm birth, fetal growth restriction and stillbirth. Guidelines for management and information to pregnant women are needed.

“…Studies have been conducted on the correlation between maternal perception of fetal movements and fetal movements detected on ultrasound scans, showing large variations, with correlation rates ranging from 16-90% 4,5 . This variation in maternal perception may be related to gestational age, amount of amniotic fluid volume, medications, fetal sleep state, obesity, anterior placenta, smoking and nulliparity 6,7 .…”
