This is an automatically translated article.

During labor, monitoring uterine contractions and fetal heart rate are extremely important, helping to assess fetal abnormalities, ensuring safety for mother and baby.

1. Monitor uterine contractions during labor


Uterine contractions are the main driving force of labor and one of the prognostic factors of childbirth. Uterine contractions are natural in nature, increasing in frequency and intensity. It is possible to actively increase and decrease uterine contractions with medication, but it cannot be stopped.
If the uterine contractions are regular, rhythmic, consistent with the clearance and dilation of the cervix, the pregnant woman's condition is having a good prognosis.
Latent stage: appear 2 - 3 contractions /10 minutes Cervix dilated 5-6cm: appear 3 - 5 contractions/10 minutes Cervix fully dilate and labor: appear 4-6 attacks/10 minutes If uterine contractions are abnormal, e.g., contractions are asynchronous, intense in frequency, above average, or occur more than 6 contractions in 10 minutes regardless of uterine dilation any bow, or the contraction is too strong, it needs immediate intervention. There is a possibility of placental abruption, uterine rupture, or fetal distress.

On the contrary, if the uterine contractions are too weak, the contractions appear too little, which is also a sign of poor labor prognosis, which can cause fetal distress, postpartum bleeding, postpartum infection.

2. Monitor fetal heart during labor


The purpose of fetal heart rate monitoring during labor is to determine the fetal condition. It is possible to monitor the fetal heart from the outside or from the inside. Most cases are followed up outside. Only in some special cases does internal tracking apply.
Monitor the fetal heart outside: use a fetal heart stethoscope with a Doppler probe on the pregnant woman's abdomen to listen to the fetal heart rate. Can test about every 30 minutes. If there is a problem with normal playback, then the frequency of checking will be more frequent. In addition, the fetal electrocardiogram can be monitored by using 2 belts containing monitoring devices attached to the pregnant woman's abdomen. Through these devices, the baby's heart rate and uterine contractions will also be displayed. The sensor wire is attached to the pregnant woman's abdomen during labor. Internal monitoring: the doctor places a small electrode directly on the baby to monitor the fetal heart. Electrodes are attached to the baby by threading through the cervix, into the uterus, and attached to the baby's scalp. In addition, a sensor is attached to the pregnant woman's leg. This method can accurately monitor the fetal heart rate and the mother's uterine contractions.

Fetal heart rate < 110 beats/min. Fetal heart rate > 160 beats/min Fetal heart rate is irregular or does not increase when baby moves or during contractions
