Antepartum haemorrhage (APH) is defined as bleeding from or in to the genital tract, occurring from 24+0 weeks of pregnancy and prior to the birth of the baby. The most important causes of APH are placenta praevia
What is APH and symptoms?
Symptoms of antepartum haemorrhage (APH) consist of vaginal bleeding in late pregnancy and before delivery. Along with vaginal bleeding other symptoms may be- (a) In APH due to placenta previa, vaginal bleeding is painless, or bleeding occurs after sexual intercourse.
What is PPH and APH?
Antepartum haemorrhage (APH) is usually defined as bleeding from the birth canal after the 24th week of pregnancy. It can occur at any time until the second stage of labour is complete; bleeding following the birth of the baby is postpartum haemorrhage.
How do you treat APH?
In general, the patient’s usual chronic medications should be continued. In the patient who has APH due to placenta previa, magnesium sulfate may be used as a tocolytic to allow the administration of betamethasone to mature the fetal lung and to allow the obstetrician to better time delivery.What are the complications of antepartum hemorrhage?
Maternal complications of APH are malpresentation, premature labour, postpartum hemorrhage, shock, retained placenta. They also include higher rates of caesarian section, peripartum hysterectomy, coagulation failure, puerperal infections and even death.
What is the cause of a low placenta?
Risk factors for developing placenta previa unusual position of the baby, including breech (buttocks first) or transverse (lying horizontally across the womb) previous surgeries that involve the uterus: cesarean delivery, surgery to remove uterine fibroids, dilation and curettage (D&C)
What is a Couvelaire uterus?
Couvelaire uterus is caused when haemorrhage from placental blood vessels seeps into decidua basalis causing placental separation, followed by infiltration in the lateral portions of the uterus. 3. Occasionally, the infiltrations reach the peritoneal cavity. Couvelaire uterus is managed conservatively.
How can you prevent APH?
Use of aspirin before 16 weeks of pregnancy to prevent pre-eclampsia also appears effective at preventing antepartum bleeding. In regard to treatment, it should be considered a medical emergency (regardless of whether there is pain), as if it is left untreated it can lead to death of the mother or baby.What does APH stand for in medical terms?

What are types of APH?- Type I: the placenta is located in the lower part of the uterus but does not come close to the cervix. …
- Type II (or marginal) – the placenta touches but does not cover the cervix.
- Type III (or partial) – the placenta partially covers the cervix.
What is Circumvallate placenta in pregnancy?
Circumvallate placenta is a placental morphological abnormality, a subtype of placenta extrachorialis in which the fetal membranes (chorion and amnion) “double back” on the fetal side around the edge of the placenta. After delivery, a circumvallate placenta has a thick ring of membranes on its fetal surface.
What are Myometrial cells?
17743. Anatomical terminology. The myometrium is the middle layer of the uterine wall, consisting mainly of uterine smooth muscle cells (also called uterine myocytes) but also of supporting stromal and vascular tissue. Its main function is to induce uterine contractions.
What is the decidua basalis?
human pregnancy …of cells known as the decidua basalis, the maternal component of the mature placenta; it is cast off when the placenta is expelled. The fetal part of the placenta—the villi and their contained blood vessels—is separated from the decidua basalis by a lakelike body of fluid blood.
How is Couvelaire uterus diagnosed?
Alexandre Couvelaire, a French obstetrician in 1912, Couvelaire uterus is typically associ- ated with abruptio placentae, the premature separation of the placenta, enabling blood to penetrate the myometrium and parametrium. 2 Diagnosis is made by direct visualization dur- ing cesarean section or biopsy.
Does placenta decide baby gender?
The study concluded that while the location of the placenta had “significant relation with fetal gender,” more research is needed. So having an anterior placenta doesn’t indicate with certainty that you’re having a girl.
In which week placenta moves up?
They’re usually spotted on your routine 20-week ultrasound. As the uterus grows upwards, the placenta is likely to move away from the cervix. Your midwife will check for this during an extra scan at 32 weeks (RCOG, 2018a).
Can I climb stairs with low lying placenta?
Yes. As long as your pregnancy is progressing smoothly and there are no complications, you may climb stairs throughout pregnancy.

What does Ari mean in medical terms?
Associated terms. Strictly speaking, ARI means acute respiratory infection.
Is circumvallate placenta serious?
Circumvallate placenta is an abnormality of the placenta. It causes the membranes of the placenta to fold back around its edges. It can increase the chance of complications such as preterm delivery and placental abruption, as well as increasing the risk of neonatal death and an emergency cesarean.
Can circumvallate placenta be misdiagnosed?
Circumvallate placenta may be misdiagnosed as an amniotic band since the raised membranes in ultrasonography may appear as a band crossing the gestational sac. If a circumvallate placenta is diagnosed at ultrasound examination, the pregnancy can be classified as high risk.
What does TRV mean on an ultrasound?
The acronyms are TRV (transverse), RT (right), LT (left), INF and I (inferior), MID (midpoint), SUP and S (superior), SAG (sagittal), LAT and L (lateral), MED and M (medial), color (Doppler color flow assessment), TX (transducer), AP (anteroposterior)
What is Myometrial contraction in pregnancy?
Its middle muscular layer is called the myometrium, which is known for its rhythmic contractions which result in ‘endometrial waves’ in the nonpregnant uterus, Braxton Hicks contractions during pregnancy, and true labor towards the end of the third trimester.
What is Perimetrium?
The perimetrium is the outer serous layer of the uterus. The serous layer secretes a lubricating fluid that helps to reduce friction. The perimetrium is also part of the peritoneum that covers some of the organs of the pelvis.
What hormone causes myometrial contraction during childbirth?
Oxytocin is an important hormone in labour and birth, when it helps the labouring woman’s uterus to contract and birth her baby.
What is chorionic Frondosum?
In pregnancy: The uterus and the development of the placenta. The chorion frondosum is that part of the conceptus that forms as the villi grow larger on the side of the chorionic shell next to the uterine wall. The discus-shaped placenta develops from the chorion frondosum and the decidua basalis.
Does Decidual reaction mean pregnancy?
During pregnancy The decidual reaction is seen in very early pregnancy in the generalized area where the blastocyst contacts the endometrial decidua. It consists of an increase in secretory functions of the endometrium at the area of implantation, as well as a surrounding stroma that becomes edematous.
What is chorionic membrane?
Chorion. The chorionic membrane is a fibrous tissue layer containing the fetal blood vessels. Chorionic villi form on the outer surface of the chorion, which maximise surface area for contact with maternal blood. The chorionic villi are involved in fetal-maternal exchange.
What is Uteroplacental?
Medical Definition of uteroplacental : of or relating to the uterus and the placenta uteroplacental circulation.
What causes uterine tetany?
Tetany can be the result of an electrolyte imbalance. Most often, it’s a dramatically low calcium level, also known as hypocalcemia. Tetany can also be caused by magnesium deficiency or too little potassium. Having too much acid (acidosis) or too much alkali (alkalosis) in the body can also result in tetany.
Is uterine rupture painful?
Common signs of uterine rupture include searing abdominal pain — a sensation that something is “ripping” — followed by diffuse pain and tenderness in the abdomen during labor. This pain can be felt even if you’ve had an epidural.
