Resuscitative Hysterotomy
A resuscitative hysterotomy, also referred to as a perimortem Caesarean section (PMCS) or perimortem Caesarean delivery (PMCD), is a hysterotomy performed to resuscitate a woman in middle to late pregnancy who has entered cardiac arrest. Combined with a laparotomy, the procedure results in a Caesarean section that removes the fetus, thereby abolishing the aortocaval compression caused by the pregnant uterus. This improves the mother's chances of return of spontaneous circulation, and may potentially also deliver a viable neonate. The procedure may be performed by obstetricians, emergency physicians or surgeons depending on the situation. Medical uses Where cardiac arrest occurs in a pregnant woman, irrespective of the condition of the fetus, the procedure should be performed immediately if basic and advanced life support attempts are proving unsuccessful at achieving return of spontaneous circulation, and the woman's uterus is deemed capable of causing aortocaval compression.

Hysterotomy
A hysterotomy is an incision made in the uterus. This surgical incision is used in several medical procedures, including during termination of pregnancy in the second trimester (or abortion) and delivering the fetus during caesarean section. It is also used to gain access and perform surgery on a fetus during pregnancy to correct birth defects, and it is an option to achieve resuscitation if cardiac arrest occurs during pregnancy and it is necessary to remove the fetus from the uterus. There are several types of incisions that can be made, including a midline vertical incision and a low transverse incision. The incision is made using a scalpel and is about 1-2 cm long, but it can be longer depending on the procedure that is performed. Other types of incisions are low transverse incision with T-extension in the midline, low transverse incision with J-extension, and low transverse incision with U-extension. These are used when low transverse incisions do not provide enough space in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Operating Theatre
An operating theater (also known as an operating room (OR), operating suite, or operation suite) is a facility within a hospital where surgical operations are carried out in an aseptic environment. Historically, the term "operating theater" referred to a non-sterile, tiered theater or amphitheater in which students and other spectators could watch surgeons perform surgery. Contemporary operating rooms are usually devoid of a theater setting, making the term "operating theater" a misnomer in those cases. Operating rooms Operating rooms are spacious, in a cleanroom, and well-lit, typically with overhead surgical lights, and may have viewing screens and monitors. Operating rooms are generally windowless, though windows are becoming more prevalent in newly built theaters to provide clinical teams with natural light, and feature controlled temperature and humidity. Special air handlers filter the air and maintain a slightly elevated pressure. Electricity support has backup systems in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fetal Viability
Fetal viability is the ability of a human fetus to survive outside the uterus. Medical viability is generally considered to be between 23 and 24 weeks Gestational age (obstetrics), gestational age. Viability depends upon factors such as birth weight, gestational age, and the availability of advanced medical care. In Developing country, low-income countries, half of newborns born at or below 32 weeks gestational age died due to a lack of medical access; in World Bank high-income economy, high-income countries, the vast majority of newborns born above 24 weeks gestational age survive. As of 2022, the world record for the lowest gestational age newborn to survive is held by Curtis Zy-Keith Means, who was born on 5 July 2020 in the United States, at 21 weeks and 1 day gestational age, weighing 420 grams. Definitions ''Viability'', as the word has been used in the United States constitutional law since ''Roe v. Wade'', is the potential of the fetus to survive outside the uterus after bi ...

Multiple Pregnancy
A multiple birth is the culmination of one multiple pregnancy, wherein the mother gives birth to two or more babies. A term most applicable to vertebrate species, multiple births occur in most kinds of mammals, with varying frequencies. Such births are often named according to the number of offspring, as in ''twins'' and ''triplets''. In non-humans, the whole group may also be referred to as a ''litter'', and multiple births may be more common than single births. Multiple births in humans are the exception and can be exceptionally rare in the largest mammals. A multiple pregnancy may be the result of the fertilization of a single egg that then splits to create identical fetuses, or it may be the result of the fertilization of multiple eggs that create fraternal ("non-identical") fetuses, or it may be a combination of these factors. A multiple pregnancy from a single zygote is called ''monozygotic'', from two zygotes is called ''dizygotic'', or from three or more zygotes is calle ...

Gestational Age (obstetrics)
In obstetrics, gestational age is a measure of the age of a pregnancy which is taken from the beginning of the woman's last menstrual period (LMP), or the corresponding age of the gestation as estimated by a more accurate method if available. Such methods include adding 14 days to a known duration since fertilization (as is possible in in vitro fertilization), or by obstetric ultrasonography. The popularity of using this definition of gestational age is that menstrual periods are essentially always noticed, while there is usually a lack of a convenient way to discern when fertilization occurred. Gestational age is contrasted with fertilization age which takes the date of fertilization as the start date of gestation. The initiation of pregnancy for the calculation of gestational age can differ from definitions of initiation of pregnancy in context of the abortion debate or beginning of human personhood. Methods According to American College of Obstetricians and Gynecologists, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twin
Twins are two offspring produced by the same pregnancy.MedicineNet > Definition of TwinLast Editorial Review: 19 June 2000 Twins can be either ''monozygotic'' ('identical'), meaning that they develop from one zygote, which splits and forms two embryos, or ''dizygotic'' ('non-identical' or 'fraternal'), meaning that each twin develops from a separate egg and each egg is fertilized by its own sperm cell. Since identical twins develop from one zygote, they will share the same sex, while fraternal twins may or may not. In rare cases twins can have the same mother and different fathers (heteropaternal superfecundation). In contrast, a fetus that develops alone in the womb (the much more common case, in humans) is called a ''singleton'', and the general term for one offspring of a multiple birth is a ''multiple''. Unrelated look-alikes whose resemblance parallels that of twins are referred to as doppelgängers. Statistics The human twin birth rate in the United States rose 76% from ...

Navel
The navel (clinically known as the umbilicus, commonly known as the belly button or tummy button) is a protruding, flat, or hollowed area on the abdomen at the attachment site of the umbilical cord. All placental mammals have a navel, although it is generally more conspicuous in humans. Structure The umbilicus is used to visually separate the abdomen into quadrants. The umbilicus is a prominent scar on the abdomen, with its position being relatively consistent among humans. The skin around the waist at the level of the umbilicus is supplied by the tenth thoracic spinal nerve (T10 dermatome). The umbilicus itself typically lies at a vertical level corresponding to the junction between the L3 and L4 vertebrae, with a normal variation among people between the L3 and L5 vertebrae. Parts of the adult navel include the "umbilical cord remnant" or "umbilical tip", which is the often protruding scar left by the detachment of the umbilical cord. This is located in the center of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
