Braxton Hicks Contractions
Braxton Hicks contractions, also known as practice contractions or false labor, are sporadic uterine contractions that may start around six weeks into a pregnancy. However, they are usually felt in the second or third trimester of pregnancy. Associated conditions Braxton Hicks contractions are often confused for labor. Braxton Hicks contractions allow the pregnant woman's body to prepare for labor. However, the presence of Braxton Hicks contractions does not mean a woman is in labor or even that labor is about to commence. Another common cause of pain in pregnancy is round ligament pain. Pathophysiology Although the exact causes of Braxton Hicks contractions are not fully understood, there are known triggers that cause Braxton Hicks contractions, such as when a pregnant woman: * is dehydrated * has a full bladder * has just had sexual intercourse * has been exercising (running, lifting heavy objects) * is under excessive stress * has had her stomach touched There are ...

Obstetrics
Obstetrics is the field of study concentrated on pregnancy, childbirth and the postpartum period. As a medical specialty, obstetrics is combined with gynecology under the discipline known as obstetrics and gynecology (OB/GYN), which is a surgical field. Main areas Prenatal care Prenatal care is important in screening for various complications of pregnancy. This includes routine office visits with physical exams and routine lab tests along with telehealth care for women with low-risk pregnancies: Image:Ultrasound_image_of_a_fetus.jpg, 3D ultrasound of fetus (about 14 weeks gestational age) Image:Sucking his thumb and waving.jpg, Fetus at 17 weeks Image:3dultrasound 20 weeks.jpg, Fetus at 20 weeks First trimester Routine tests in the first trimester of pregnancy generally include: * Complete blood count * Blood type ** Rh-negative antenatal patients should receive RhoGAM at 28 weeks to prevent Rh disease. * Indirect Coombs test (AGT) to assess risk of hem ...

Contraction (childbirth)
Uterine contractions are muscle contractions of the uterine smooth muscle that can occur at various intensities in both the non-pregnant and pregnant uterine state. The non-pregnant uterus undergoes small, spontaneous contractions in addition to stronger, coordinated contractions during the menstrual cycle and orgasm. Throughout gestation, the uterus enters a state of uterine quiescence due to various neural and hormonal changes. During this state, the uterus undergoes little to no contractions, though spontaneous contractions still occur for the uterine myocyte cells to experience hypertrophy. The pregnant uterus only contracts strongly during orgasms, labour, and in the postpartum stage to return to its natural size. Throughout menstrual cycle Uterine contractions that occur throughout the menstrual cycle, also termed ''endometrial waves'' or ''contractile waves'', appear to involve only the sub-endometrial layer of the myometrium. Follicular and luteal phase In the early folli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second Trimester
Pregnancy is the time during which one or more offspring gestates inside a woman's uterus. A multiple pregnancy involves more than one offspring, such as with twins. Conception usually occurs following vaginal intercourse, but can also occur through assisted reproductive technology procedures. A pregnancy may end in a live birth, a miscarriage, an induced abortion, or a stillbirth. Childbirth typically occurs around 40 weeks from the start of the last menstrual period (LMP), a span known as the ''gestational age''; this is just over nine months. Counting by ''fertilization age'', the length is about 38 weeks. Implantation occurs on average 8–9 days after fertilization. An ''embryo'' is the term for the developing offspring during the first seven weeks following implantation (i.e. ten weeks' gestational age), after which the term ''fetus'' is used until the birth of a ''baby''. Signs and symptoms of early pregnancy may include missed periods, tende ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Round Ligament Pain
Round ligament pain (RLP) is pain associated with the round ligament of the uterus, usually during pregnancy. RLP is one of the most common discomforts of pregnancy and usually starts at the second trimester of gestation and continues until delivery. It usually resolves completely after delivery although cases of postpartum RLP (that is, RLP that persisted for a few days after delivery) have been reported. RLP also occurs in nonpregnant women. The round ligament of the uterus goes from the pelvis, passes through the internal abdominal ring, and runs along the inguinal canal to the labia majora. It is the structure that holds the uterus suspended inside the abdominal cavity.Aguilera PA. (Pregnancy, Round Ligament Pain http://www.webmd.com/baby/pregnancy-round-ligament-pain) WebMD.

Cervical Dilation
Cervical dilation (or cervical dilatation) is the opening of the cervix, the entrance to the uterus, during childbirth, miscarriage, induced abortion, or gynecological surgery. Cervical dilation may occur naturally, or may be induced surgically or medically. In childbirth In the later stages of pregnancy, the cervix may already have opened up to 1–3 cm (or more in rarer circumstances), but during labor, repeated uterine contractions lead to further widening of the cervix to about 6 centimeters. From that point, pressure from the presenting part (head in vertex births or bottom in breech births), along with uterine contractions, will dilate the cervix to 10 centimeters, which is "complete." Cervical dilation is accompanied by effacement, the thinning of the cervix. General guidelines for cervical dilation: * Latent phase: 0–3 centimeters * Active labor: 4–7 centimeters * Transition: 8–10 centimeters * Complete: 10 centimeters. Delivery of the infant takes place ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Braxton Hicks
John Braxton Hicks (23 February 1823 – 28 August 1897) was a 19th-century English medical doctor who specialised in obstetrics. Early life and education He was born to banker Edward Hicks (b. 1785 - d. 1861) in Rye, Sussex. He was educated privately and in 1841 entered Guy's Hospital Medical School. He obtained his MB at the University of London in 1845 and an MD in 1851. He was elected a Fellow of the Royal College of Physicians in 1866. Career In 1856 Hicks was appointed assistant obstetric physician at Guy's Hospital and full physician in 1868. In 1888 he became obstetric physician at St Mary's Hospital, London. Hicks was the first physician to describe the bipolar and other methods of the version of a fetus. In 1872, he described the uterine contractions not resulting in childbirth now known as Braxton Hicks contractions. In 1862 he was elected a Fellow of the Royal Society by virtue of his interest in Natural History, about which he wrote numerous papers. ...

The English people are an ethnic group and nation native to England, who speak the English language in England, English language, a West Germanic languages, West Germanic language, and share a common ancestry, history, and culture.
