Continuing Education Activity

Braxton-Hicks contractions, also known as prodromal or false labor pains, are contractions of the uterus that typically are not felt until the second or third trimester of the pregnancy. Braxton-Hicks contractions are the body's way of preparing for true labor, but they do not indicate that labor has begun. Because many pregnant patients have not been educated about Braxton-Hicks contractions, they often seek care and undergo unnecessary evaluation for these contractions. This activity reviews the evaluation and management of patients with Braxton-Hicks contractions and highlights the role of the interprofessional team in educating the patient about the condition.

Objectives:

Describe the etiology of Braxton-Hicks contractions.
Review the presentation of a patient with Braxton-Hicks contractions.
Explain how to evaluate a patient with Braxton-Hicks contractions.
Employ strategies to improve interprofessional communication, which will improve outcomes in patients with Braxton-Hicks contractions.

Introduction

Braxton Hicks contractions are sporadic contractions and relaxation of the uterine muscle. Sometimes, they are referred to as prodromal or “false labor" pains. It is believed they start around 6 weeks gestation but usually are not felt until the second or third trimester of the pregnancy. Braxton Hicks contractions are the body's way of preparing for true labor, but they do not indicate that labor has begun or is going to start.

Braxton Hicks contractions are a normal part of pregnancy. They may be uncomfortable, but they are not painful. Women describe Braxton Hicks contractions as feeling like mild menstrual cramps or a tightening in a specific area of the abdomen that comes and goes. [1][2][3]

Braxton Hicks contractions can be differentiated from the contractions of true labor. Braxton Hicks contractions are irregular in duration and intensity, occur infrequently, are unpredictable and non-rhythmic, and are more uncomfortable than painful. Unlike true labor contractions, Braxton Hicks contractions do not increase in frequency, duration, or intensity. Also, they lessen and then disappear, only to reappear at some time in the future. Braxton Hicks contractions tend to increase in frequency and intensity near the end of the pregnancy. Women often mistake Braxton Hicks contractions for true labor. However, unlike true labor contractions, Braxton Hicks contractions do not cause dilatation of the cervix and do not culminate in birth.

Etiology

Braxton Hicks contractions are caused when the muscle fibers in the uterus tighten and relax. The exact etiology of Braxton Hicks contractions is unknown. However, there are known circumstances that trigger Braxton Hicks contractions including when the woman is very active, when the bladder is full, following sexual activity, and when the woman is dehydrated. A commonality among all these triggers is the potential for stress to the fetus, and the need for increased blood flow to the placenta to provide fetal oxygenation.[4][5][6]

Epidemiology

Braxton Hicks contractions are present in all pregnancies. However, each woman's experience is different. Most women become aware of Braxton Hicks contractions in the third trimester, and some women are aware of them as early as the second trimester. Sometimes Braxton Hick contractions occurring near the end of the third trimester of pregnancy are mistaken as the onset of true labor. It is not unusual, especially in a first pregnancy, for a woman to think she is in labor only to be told it is Braxton Hicks contractions and not true labor.

Pathophysiology

Braxton Hicks contractions are thought to play a role in toning the uterine muscle in preparation for the birth process. Sometimes Braxton Hicks contractions are referred to as "practice for labor." Braxton Hicks contractions do not result in dilation of the cervix but may have a role in cervical softening.

The intermittent contraction of the uterine muscle may also play a role in promoting blood flow to the placenta. Oxygen-rich blood fills the intervillous spaces of the uterus where the pressure is relatively low. The presence of Braxton Hicks contractions causes the blood to flow up to the chorionic plate on the fetal side of the placenta. From there the oxygen-rich blood enters the fetal circulation.

History and Physical

When assessing a woman for the presence of Braxton Hicks contractions, there are some key questions to ask. Her response to these questions will assist the healthcare provider to differentiate Braxton Hicks contractions and true labor contractions.[7][8][9]

How often are the contractions? Braxton Hicks contractions are irregular and do not get closer together over time. True labor contractions come at regular intervals, and as time goes on, they get closer together and stronger.
How long are the contractions? Braxton Hicks contractions are unpredictable. They may last less than 30 seconds or up to 2 minutes. True labor contractions last between 30 to less than 90 seconds and become longer over time.
How strong are the contractions? Braxton Hicks contractions are usually weak and either stay the same or become weaker and then disappear. True labor contractions get stronger over time.
Where are the contractions felt? Braxton Hicks contractions are often only felt in the front of the abdomen or one specific area. True labor contractions start in the midback and wrap around the abdomen towards the midline.
Do the contractions change with movement? Braxton Hicks contractions may stop with a change in activity level or as the woman changes position. If she can sleep through the contraction, it is a Braxton Hicks contraction. True labor contractions continue and may even become stronger with movement or position change.

During the physical assessment, the provider may palpate an area of tightening or a "spasm" of the uterine muscle, but the presence of a uterine contraction in the uterine fundus is not palpable. The woman will be assessed for the presence of uterine bleeding or rupture of the amniotic membrane. An examination of the cervix reveals no change in effacement or dilatation as a result of the Braxton Hicks contractions.

Evaluation

There are no laboratory or radiographic tests to diagnose Braxton Hicks contractions. Evaluation of the presence of Braxton Hicks contractions is based on an assessment of the pregnant woman's abdomen, specifically palpating the contractions.

Treatment / Management

By the midpoint of pregnancy, the woman and provider should discuss what the woman may experience during the remainder of the pregnancy. Braxton Hicks contractions are one of the normal events a woman may experience. Teaching her about Braxton Hicks contractions will help her to be informed and to decrease her anxiety if they occur.[10][11][12]

There is no medical treatment for Braxton Hicks contractions. However, taking action to change the situation that triggered the Braxton Hicks contractions is warranted. Some actions to ease Braxton Hicks contractions include:

Changing position or activity level: if the woman has been very active, lie down; if the woman has been sitting for an extended time, go for a walk.
Relaxing: take a warm bath, get a massage, read a book, listen to music, or take a nap.
Drinking water to rehydrate.

If these actions do not lessen the Braxton Hicks contractions or if the contractions continue and are becoming more frequent or more intense, the patient's healthcare provider should be contacted.

Also, if any of the following are present the healthcare provider should be contacted immediately:

Vaginal bleeding
Leaking of fluid from the vagina
Strong contractions every 5-minutes for an hour
Contractions that the woman is unable to "walk through"
A noticeable change in fetal movement, or if there are less than ten movements every 2 hours.

Differential Diagnosis

Amenorrhea

Ascites

Full bladder

Hematometra

Nausea

Ovarian cysts

Pseudocyesis

Uterine fibroids

Vomiting

Pearls and Other Issues

In addition to Braxton Hicks contractions, there are other causes of abdominal pain during pregnancy. Some normal reasons for abdominal pain during pregnancy, in addition to Braxton Hicks contractions and true labor contractions, include:

Round ligament pain or a sharp, jabbing feeling felt in the lower abdomen or groin area on one or both sides.
Higher levels of progesterone can cause excess gas during pregnancy.
Constipation may be a source of abdominal pain.

Circumstances in which abdominal pain is a sign of a serious condition that requires immediate medical attention include:

Ectopic pregnancy.
Placental abruption. A key symptom of placental abruption is intense and constant pain that causes the uterus to become hard for an extended period without relief.
Urinary tract infection symptoms include pain and discomfort in the lower abdomen as well as burning with urination.
Preeclampsia is a condition of pregnancy occurring after 20-weeks gestation and characterized by high blood pressure and protein in the urine. Upper abdominal pain, usually under the ribs on the right side, can be present in preeclampsia.

If a woman is unsure if she is experiencing Braxton Hicks contractions or another condition, a discussion with a healthcare provider is needed. The healthcare provider may recommend a visit to the office setting or labor and delivery for an examination by a healthcare professional to determine the cause of the abdominal pain.

Enhancing Healthcare Team Outcomes

Braxton hicks contractions are fairly common and it is important for the emergency department physician labor & delivery nurse and nurse practitioner to be aware that this is not true labor. If there is any doubt, the obstetrician should be consulted. However, at the same time, the onus is on the healthcare workers to rule out true labor. Other organic disorders like appendicitis, urinary tract infection or cholecystitis must also be ruled out. With the right education, patients with braxton hicks contraction will not needlessly rush to the ED every time they sense a contraction.

Understanding and Identifying Braxton Hicks Contractions

The doctors and midwives at All About Women of Gainesville and Lake City, FL discuss how you can distinguish between Braxton Hicks vs. real labor contractions

Whether you're 22 or 35 weeks along, pregnant with your first baby or your third, Braxton Hicks contractions can take you by surprise and even trick you into thinking you're entering labor. Also called "warm- up" or "toning" contractions, Braxton Hicks contractions are your body's way of preparing the uterus for labor. And they can send even the most seasoned mother to the hospital – only for her to find out that her Braxton Hicks are causing "false labor."

Many women report having more of these contractions later in the day when they are tired or haven't had enough to drink. If you're having lots of Braxton Hicks contractions, don't stop your normal activities, but do make sure you stay well hydrated and take some time to get off your feet during the day.

Understanding Braxton Hicks contractions during pregnancy - when they occur, what they're like, and how to relieve them, as well as how your true labor contractions will differ - can help you interpret what is occurring in your body, and when it's really time to go to the hospital or call your OB doctor.

When Do Braxton Hicks Contractions Start During Pregnancy?

As with most all pregnancy matters, Braxton Hicks contractions are different for every woman. All pregnant women experience these contractions but not all expecting mothers are aware they occur. Some women don't feel any kind of contraction until delivery day, and that is completely normal. You don't need to worry if you haven't felt any warm-up contractions.

Many women, however, do feel their Braxton Hicks contractions, usually any time after the 20- week marker of pregnancy. While some women feel them this early, others may not experience any until the later weeks of pregnancy. In second and third pregnancies, some mothers say they're Braxton Hicks contractions start earlier.

What Do Braxton Hicks Contractions Feel Like?

Braxton Hicks contractions often begin very mildly, feeling like a tightening sensation across the uterus. They may become stronger in the later weeks of pregnancy. Their strength and recurrence is how expecting mothers confuse them with true labor contractions.

The job of a true labor contraction is to dilate the cervix. Braxton Hicks contractions, you may remember, work only to tone the uterus and do not cause the cervix to dilate. Of course, you can't tell if your cervix is dilated unless you go in and have your obstetrician or midwife check you, but Braxton Hicks contractions have other distinct characteristics like:

Their intensity doesn't change. Braxton Hicks contractions usually remain fairly weak, while true labor contractions grow increasingly intense.

They go away with a change in activity. If you're sitting down and having Braxton-Hicks contractions, they will usually go away if you get up and walk around. If you've been moving around, the opposite is true – try resting for a while and the contractions should go away. True contractions, on the other hand, do not go away with changes in activity.

They feel like a tightening across the front of the uterus. True labor contractions, on the other hand, wrap from the top of the abdomen down, and wrap across the front of the abdomen and around the back.

They are irregular. The length and frequency of Braxton Hicks contraction varies. True labor contractions occur at regular intervals and last at least thirty seconds. Real contractions will also grow longer and closer together.

What Causes Braxton Hicks Contractions?

While they may occur without reason, there are some known life factors that cause women to have Braxton Hicks contractions:

Strenuous exercise or activity
Dehydration

Sex, particularly orgasm
Someone touching the mother's belly

Many women report having more of these contractions later in the day when they are tired or haven't had enough to drink. If you're having lots of Braxton Hicks contractions, don't stop your normal activities, but do make sure that you stay well hydrated and take some time to get off your feet during the day. A warm bath or a cup of tea can also help to relieve your contractions.

Accompanying Signs of Early Labor

If you are getting close to your due date and are experiencing contractions, you should be aware of the signs of early labor that accompany true labor contractions:

Lower back ache, or pain in your abdomen or pelvis
Loose stools
Brown-tinged mucous

Watery discharge
Increased urination

If you experience any of these signs along with regularly occurring contractions, you are probably in labor. You may not need to go to the hospital right away, but you should contact your OB doctor or midwife to let them know what symptoms you are experiencing and how far apart your contractions are.

Braxton Hicks contractions present themselves so differently in successive pregnancies that even the most seasoned mothers can be confused , not to mention first-time mothers. The best way to have peace of mind about these contractions, besides educating yourself, is to stay in close contact with your OB doctor and midwife.

Florida's obstetricians and midwives at All About Women want you to feel confident with every step of your pregnancy. If you're concerned about contractions, or think you a re pregnant and need to ensure you and your baby are healthy, contact our Gainesville or Lake City office to schedule an appointment today.

false or real / “Waiting for the baby”

How to distinguish them from real contractions, and why they are needed, we will try to find out.

The phenomenon of temporary contractions was first described by the English doctor John Braxton Hicks. That is why they are called - Braxton Hicks contractions or false, training contractions, precursor contractions. In his scientific work of 1872, he argued that these contractions are short-term (from half a minute to 2 minutes) contractions of the muscles of the uterus, which are felt by a pregnant woman as an increase in the tone of the uterus. They appear after the 20th week of pregnancy. And during the day they happen often, but the expectant mother in the daytime may not even notice them. However, as time goes on, they intensify, becoming more and more obvious.

WHAT DO YOU NEED FALSE BROUGHT

The uterus is a muscular organ. And like any muscle that has to perform the work allotted to it in the body, it needs training. After all, if she hangs for all forty weeks like a bag, she will not cope with the load in childbirth. Thus, the purpose of training or false contractions is to prepare the uterus and cervix for childbirth. That is why one of the names of training bouts is contractions harbingers - harbingers of an approaching birth.

ARE FALSE PARTS PAINFUL?

As a rule, false contractions are painless, but with increasing duration they become more noticeable and bring more discomfort. However, in all women, they manifest themselves in different ways, someone does not feel them at all, and someone does not sleep at night, tossing and turning and trying to find a comfortable position for sleeping. It all depends on the pain threshold. The main thing in this situation is to stop being nervous about this and calm yourself with the thought that such training is necessary for the most important upcoming event - the birth of your crumbs. And to calm down a little and sleep better, ask your doctor to prescribe a sedative for you and get a special pillow for expectant and nursing mothers. With her, falling asleep and experiencing the discomfort of the last weeks of pregnancy will be much easier!

HOW TO LIVE WITH FREQUENT PARTS

Some expectant mothers complain that their Braxton Hicks contractions are frequent and cause significant discomfort, even when they are doing housework or other light physical activity. In such a situation, obstetricians are advised to lie down or vice versa, take an easy walk, in any case, change the type of activity. If training contractions bother you a lot, it is recommended to drink a glass of water, juice or herbal tea, calm down and get some rest. Ask someone close to give you a massage. Lie in silence. And to also benefit from training fights, try doing breathing exercises: practice breathing techniques in childbirth in practice.

HOW TO DIFFERENTIATE TRAINING FROM LIVING

The most important thing to understand is that real contractions are much more painful than Braxton Hicks contractions. You will understand it right away. In addition, the contractions that bring you closer to childbirth are more regular. The contractions begin in the lower back, spread to the front of the abdomen, and occur every 10 minutes (or more than 5 contractions per hour). Then they occur with an interval of about 30-70 seconds and over time the intervals between them are reduced. Some women describe the sensations of labor pains as severe menstrual cramps, or sensations during diarrhea, when the pain rolls in waves in the abdomen. These contractions, unlike false ones, continue even after a change in position and when walking, constantly intensifying. As soon as you feel all these symptoms, call your ob-gyn - hour X has arrived. If in doubt, also do not be afraid to disturb the doctor. The doctor will ask you a few questions that will help him determine the type of contractions and eliminate all your doubts and worries. After all, it is always better to consult a doctor and trust his professional experience.

You should seek help if:

• you have more than four contractions an hour and they happen regularly
• contractions are accompanied by pain in the lower spine
• contractions are accompanied by watery or bloody vaginal discharge
• the contractions are so strong that it is very difficult for you to endure them
• there is a marked change in the child's movement, or less than 10 movements every 2 hours
• you think your waters have started to break

Alla Misyutina, Consultant Physician, Independent Laboratory INVITRO

Dear women, during labor, the body needs a lot of oxygen, so proper breathing is very important. A large influx of oxygen into the blood of mother and baby alleviates the condition of the crumbs, which during childbirth experiences oxygen starvation. Special breathing techniques help to properly open the birth canal and make contractions and attempts as effective as possible.

Different types of breathing should be used at different stages of labor.

• During "false" contractions, breathing should be deep and slow. During the period when the contractions become more intense, it is necessary to use "pain-relieving breathing". This breathing is slow, deep, the inhalation is done through the nose, it should be longer than the exhalation through the mouth. More details: inhale is done at the expense of 1-2-3-4, and exhale - at the expense of 1-2-3-4-5-6. With the help of such breathing: mom relaxes, distracts from pain, focuses on the score; the baby receives as much as possible, so he needs oxygen.
• In breaks from contractions, you need to rest and breathe evenly without any effort, so that you can then easily follow the doctor's recommendations.
• During attempts, you need to exhale all the air from the lungs, then take a deep breath and push for up to 6-9 seconds. Quickly exhale all the air, quickly take a deep breath and again hold your breath for 6-9 seconds, and so on - about three times per attempt.
• In breaks from attempts to rest and breathe deeply, evenly and relaxed.
• It is very important to only push on the perineum and never push on the head. In this case, all efforts are wasted and will appear in the form of burst vessels in the eyes and on the face.
• In the period after the birth of the head, it is necessary to stop pushing and breathing shallowly, some call this breathing “dog-like”, deep breathing can harm both mom and baby. Then everything goes on as usual, the main thing is to obey the doctor.
• After the baby was born, within half an hour the last stage of labor begins - the birth of the placenta. Special breathing is no longer required, at the doctor's command, push a little into the perineum and EVERYTHING! Dear women, pain during childbirth is good, it means that your baby will be born soon. There is no need to resist the pain, this is a mistake that brings a woman and a child nothing but fatigue. On the contrary, it is necessary to concentrate and help in every possible way to give birth to a healthy baby.

BIRTH AGAIN

So, you have decided that this is no longer a “teaching”, but the beginning of childbirth. In addition to contractions, the onset of labor can be indicated by the outflow of amniotic fluid and the passage of a mucous plug that closes the lumen of the cervix. The mucous plug can also come off 2-3 days before delivery. However, her departure does not always mean that it is time to go to the hospital. During pregnancy, the cervix is tightly closed. With the onset of labor pains, its opening begins: the cervix of the uterus gradually expands to 10-12 cm in diameter (full disclosure). The birth canal is preparing to "release" the child from the womb. Intrauterine pressure increases during contractions as the uterus shrinks. And in the end, this leads to rupture of the fetal bladder and the outflow of part of the amniotic fluid.

The first, preparatory, period of labor for women giving birth for the first time takes an average of 12 hours, and 2-4 hours less for those who have second births. At the beginning of the second stage of labor, contractions join the contractions - contractions of the muscles of the abdominal wall and diaphragm. In addition to the fact that different muscle groups are involved in contractions and attempts, they have one more important difference: contractions are an involuntary and uncontrollable phenomenon, neither their strength nor frequency depend on the woman in labor, while attempts to a certain extent obey her will , it can delay or strengthen them. Therefore, at this stage of childbirth, a lot depends on the expectant mother and her ability to quickly and correctly follow the commands of the obstetrician taking delivery. And most importantly - to tune in correctly and not allow panic and thoughts about something bad. Obstetricians and gynecologists recommend that mothers perceive childbirth as a holiday, a baby's birthday.
