Head Engagement
A cephalic presentation or head presentation or head-first presentation is a situation at childbirth where the fetus is in a longitudinal lie and the head enters the pelvis first; the most common form of cephalic presentation is the vertex presentation, where the occiput is the leading part (the part that first enters the birth canal). All other presentations are abnormal ( malpresentations) and are either more difficult to deliver or not deliverable by natural means. Engagement The movement of the fetus to cephalic presentation is called ''head engagement''. It occurs in the third trimester. In head engagement, the fetal head descends into the pelvic cavity so that only a small part (or none) of it can be felt abdominally. The perineum and cervix are further flattened and the head may be felt vaginally. Head engagement is known colloquially as the ''baby drop'', and in natural medicine as the ''lightening'' because of the release of pressure on the upper abdomen and renewed ...

William Smellie (obstetrician)
William Smellie (5 February 1697 – 5 March 1763) was a Scottish obstetrician and medical instructor who practiced and taught primarily in London. One of the first prominent male midwives in Britain, he designed an improved version of the obstetrical forceps, established safer delivery practices, and through his teaching and writing helped make obstetrics more scientifically based. He is often called the "father of British midwifery". Early life and education Smellie was born on 5 February 1697 in the town of Lesmahagow, Scotland. He was the only child of Sara Kennedy (1657–1727) and Archibald Smellie (1663/4–1735), a merchant and burgess of the town. Smellie practiced medicine before getting a license, opening an apothecary in 1720 in Lanark. It was not a particularly lucrative venture, as he also sold cloth as a side business to supplement his income, but he began reading medical books and teaching himself obstetrics at this time. By 1728, he was married to Eupham Borla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cephalic Presentation - Left Occipito-anterior
A head is the part of an organism which usually includes the ears, brain, forehead, cheeks, chin, eyes, nose, and mouth, each of which aid in various sensory functions such as sight, hearing, smell, and taste. Some very simple animals may not have a head, but many bilaterally symmetric forms do, regardless of size. Heads develop in animals by an evolutionary trend known as cephalization. In bilaterally symmetrical animals, nervous tissue concentrate at the anterior region, forming structures responsible for information processing. Through biological evolution, sense organs and feeding structures also concentrate into the anterior region; these collectively form the head. Human head The human head is an anatomical unit that consists of the skull, hyoid bone and cervical vertebrae. The term "skull" collectively denotes the mandible (lower jaw bone) and the cranium (upper portion of the skull that houses the brain). Sculptures of human heads are generally based on ...

Polyhydramnios
Polyhydramnios is a medical condition describing an excess of amniotic fluid in the amniotic sac. It is seen in about 1% of pregnancies. It is typically diagnosed when the amniotic fluid index (AFI) is greater than 24 cm. There are two clinical varieties of polyhydramnios: chronic polyhydramnios where excess amniotic fluid accumulates gradually, and acute polyhydramnios where excess amniotic fluid collects rapidly. The opposite to polyhydramnios is oligohydramnios, not enough amniotic fluid. Presentation Associated conditions Fetuses with polyhydramnios are at risk for a number of other problems including cord prolapse, placental abruption, premature birth and perinatal death. At delivery the baby should be checked for congenital abnormalities. Causes In most cases, the exact cause cannot be identified. A single case may have one or more causes, including intrauterine infection ( TORCH), rh-isoimmunisation, or chorioangioma of the placenta. In a multiple gestation pregn ...

Cephalopelvic Disproportion
Cephalopelvic disproportion exists when the capacity of the pelvis is inadequate to allow the fetus to negotiate the birth canal. This may be due to a small pelvis, a nongynecoid pelvic formation, a large fetus, an unfavorable orientation of the fetus, or a combination of these factors. Certain medical conditions may distort pelvic bones, such as rickets or a pelvic fracture, and lead to CPD. Transverse diagonal measurement has been proposed as a predictive method. Causes A large fetus can be one cause of CPD. A large fetus can be caused by gestational diabetes, postterm pregnancy, genetic factors, and multiparity. The shape of the pelvis can also be a cause of CPD. The pelvis may be too small, or the shape of the pelvis may be malformed. Shorter women are more likely to have CPD as are adolescents. Diagnosis Diagnosis of CPD may be made when there is failure to progress, but not all cases of prolonged labour are the result of CPD. Use of ultrasound to measure the size of ...

Anencephaly
Anencephaly is the absence of a major portion of the brain, skull, and scalp that occurs during embryonic development. It is a cephalic disorder that results from a neural tube defect that occurs when the rostral (head) end of the neural tube fails to close, usually between the 23rd and 26th day following conception. Strictly speaking, the Greek term translates as "without a brain" (or totally lacking the inside part of the head), but it is accepted that children born with this disorder usually only lack a telencephalon, the largest part of the brain consisting mainly of the cerebral hemispheres, including the neocortex, which is responsible for cognition. The remaining structure is usually covered only by a thin layer of membrane—skin, bone, meninges, etc., are all lacking. With very few exceptions, infants with this disorder do not survive longer than a few hours or days after birth. Signs and symptoms The National Institute of Neurological Disorders and Stroke (NINDS) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macrosomia
Large for gestational age (LGA) is a term used to describe infants that are born with an abnormally high weight, specifically in the 90th percentile or above, compared to other babies of the same developmental age. Macrosomia is a similar term that describes excessive birth weight, but refers to an absolute measurement, regardless of gestational age. Typically the threshold for diagnosing macrosomia is a body weight of between , or more, measured at birth, but there are difficulties reaching a universal agreement of this definition. Evaluating an infant for macrosomia or LGA can help identify risks associated with their birth, including labor complications of both the parent and the child, potential long-term health complications of the child, and infant mortality. Signs and symptoms Fetal macrosomia and LGA often do not present with noticeable patient symptoms. Important signs include large fundal height ( uterus size) and excessive amniotic fluid (polyhydramnios). Fundal heigh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Preterm
Preterm birth, also known as premature birth, is the birth of a baby at fewer than 37 weeks gestational age, as opposed to full-term delivery at approximately 40 weeks. Extreme preterm is less than 28 weeks, very early preterm birth is between 28 and 32 weeks, early preterm birth occurs between 32 and 36 weeks, late preterm birth is between 34 and 36 weeks' gestation. These babies are also known as premature babies or colloquially preemies (American English) or premmies (Australian English). Symptoms of preterm labor include uterine contractions which occur more often than every ten minutes and/or the leaking of fluid from the vagina before 37 weeks. Premature infants are at greater risk for cerebral palsy, delays in development, hearing problems and problems with their vision. The earlier a baby is born, the greater these risks will be. The cause of spontaneous preterm birth is often not known. Risk factors include diabetes, high blood pressure, multiple gestation (being ...
