Birth: what surveillance for your baby?


During delivery, your baby's heart rate will be closely monitored. A good way to know if it is sufficiently oxygenated. If necessary, other examinations will be practiced such as the measurement of the pH, the electrocardiogram, the dosage of the lactates ... Explanations.

HEART RHEUM (RCF): the method par excellence

Why ?

  • The increase of this rhythm sometimes testifies to a hyperthermia of the mother, that is to say of an elevation of the temperature of her body. Conversely, a slowdown in fetal heart rate (FHR) is a sign of fetal distress.

Its principle

  • Thanks to a sensor placed on the belly of the mother and maintained by a strap, the medical team records the cardiac activity of the fetus, its acceleration, its slowdowns, rhythm disorders. The sensor is connected to a device indicating by sounds the frequency of the beats of the heart of the future baby. The parallel presence of a graphical recording makes it possible to directly visualize the fetal heart rate and the intensity of the uterine contractions.
  • All these data reflect the good vitality and oxygenation of the future baby. At the slightest anomaly, the medical team can make the decision to speed up the delivery, or to consider a cesarean section.

The recommendations

  • During labor, cardio-fetal recording should be performed continuously, with a systematic analysis every 15 to 30 minutes depending on the existence or absence of risk factors.

Measures

  • The basic rhythm is normal between 110 and 160 beats per minute, too fast above 160 beats for more than ten minutes, too slow below 110 beats, over the same period. Side uterine activity, it is estimated the normal frequency between 2 and 5 contractions every ten minutes. Today we are thinking about a "miniaturized" monitoring, which would allow the continuous monitoring of the fetal heart rate (FHR) during work, while allowing the mobility of the mother-to-be.

INFO +

The analysis of the cardio-fetal rhythm produces many "false positives": it is wrongly thought that the baby is poorly oxygenated. This results in an increase in caesareans or instrumental extractions (cupping, forceps) not always justified.
