Impact of Braxton-Hicks contractions on fetal wellbeing
Braxton-Hicks contractions (BHC) are common painful contractions that start in the third trimester. They are random spots of uterine action that happen in the absence of sufficient gap-junction connectivity. BHC has a significant impact on fetal wellbeing.

To estimate the correlation between the maternal perception of Braxton-Hicks contractions (BHC) and fetal wellbeing throughout antepartum computerized cardiotocography (cCTG) parameters, doctors performed a prospective observational study.

Non-laboring women with a term pregnancy were recruited. They collected data regarding maternal perception of BHC in the last two weeks before delivery. For each patient, an external computerized cardiotocography (cCTG) was registered. Women were subdivided in accordance with perception or non-perception of BHC. Fifty women were recruited.

- Women who felt BHC showed higher fetal heart rate, lower long-term variability, and reduced number of accelerations.

In conclusion, the absence of a mother's perception of BHC showed lower baseline fetal heart rate, increased number of accelerations, and higher long-term variability related to mothers who perceived BHC.
