If you`re in labor, fetal monitoring will help your healthcare team monitor how your baby is doing. There are different types of fetal monitoring, and the type you need depends on your situation as well as your provider`s preference. Whenever you have a contraction, count how many seconds it lasts. When it`s over, note the time and how many seconds the contraction lasted. If you have more than four contractions in an hour, empty your bladder again, drink at least two 8-ounce glasses of water, and monitor for a second hour. If the contractions get closer or become painful, call your doctor. An advantage of electronic monitoring over the fetoscope method was that it could be performed without the provider having to be at the bedside. It can be hard to know if you`re really at work. Sometimes your uterus contracts, but labor has not yet begun. This is called “bad work.” These contractions are called Braxton Hicks contractions. They can occur as early as the second trimester. However, they are most often felt in the third trimester, if at all.
It is common to have false contractions – Braxton Hicks contractions – in the last weeks of pregnancy. These contractions are called false contractions because they do not cause the cervix to expand (dilation) or thinning (extinction). These contractions can be regular and painful. They usually disappear in about an hour with rest. Count how many contractions you have in 20 minutes and how many you have in an hour. If you have regular contractions 4 times every 20 minutes or 8 times an hour that last more than an hour, call your doctor`s office immediately. Ayres-de-Campos D. Electronic fetal monitoring or cardiotocography, 50 years later: what`s in a name? At J Obstet Gynecol. 2018;218(6):545-546. doi:10.1016/j.ajog.2018.03.011 Fetal surveillance, in one form or another, has been around for a long time – more than 350 years, in fact.
Prior to the 1970s, a health care provider (usually a doctor, nurse, or midwife) used a stethoscope designed for pregnancy (fetoscope) to hear the heart sounds (auscultation) of a fetus. No one type of fetal monitoring will suit everyone. The frequency with which it is necessary to check the baby and contractions will vary from person to person – and even from birth to labor with the same person. If your work is considered high-risk, you will likely need ongoing fetal monitoring. Alfirevic Z, Devane D, Gyte GM, Cuthbert A. Continuous cardiotocography (CTG) as a form of electronic fetal monitoring (EFM) for fetal assessment during labour. Cochrane Database Syst Rev. 2017;2(2):CD006066.
doi:10.1002/14651858.CD006066.pub3 In most pregnancies, Braxton Hicks contractions are tolerable and do not interfere with daily activities. But for some pregnancies, they are very troublesome due to pain, discomfort and lack of sleep, and even cause trips to work and delivery to exclude labor. Fortunately, these types of Braxton Hicks contractions are towards the end of pregnancy and short-lived. The term appeared in 1872 when an English physician named John Braxton Hicks described contractions that occur before actual birth. Also known as “false contractions” or “exercise contractions,” these contractions can begin as early as the second trimester, but are more common in the third trimester. Electronic fetal monitoring technology came to market in the 1960s and 1970s, but had to undergo reliability testing before hospitals and clinics began using it. Electronic fetal monitors provided a graph (first on a paper print and later on a computer screen) showing how a fetus` heart rate reacted to contractions. Physically, fetal monitoring can be performed outdoors or indoors. The timing of monitoring can be continuous or intermittent. Stout MJ, Cahill AG.
