An analysis of expulsion of a fetus

The examinations described here were made in order to answer the question - how often, in spite of suspicious CTG patterns during the second stage of labor, were the fetal blood tests normal, and a spontaneous delivery or a further propulsion of the presenting part could be expected? The data of patients formed the statistical basis for this survey; these patients were delivered at the Department of Obstetrics in Berlin- Neuk olln Hospital during the period from September to September Each patient had a suspicious Hammacher Score greater than or equal to 3 points during the second stage of labor, and due to this, the fetal acid-base balance had been examined. It was shown that with an increase in CTG score points the proportion of pH levels less than or equal to 7.

Download PDF Abstract Accurately defining and reporting perinatal deaths ie, fetal and infant deaths is a critical first step in understanding the magnitude and causes of these important events. In addition to obstetric health care providers, neonatologists and pediatricians should know the current US definitions and reporting requirements for live births, fetal deaths, and infant deaths.

Correct identification of these vital events will improve our local, state, and national data so that these deaths can be better addressed and reduced. In the United States inthe fetal mortality rate for gestations of at least 20 weeks 6.

Understanding the etiologies of these events and predicting risk begins with accurately defining cases; the collection and analysis of reliable statistical data are an essential part of in-depth investigations on local, state, and national levels.

Fetal and infant deaths occur within the clinical practice of several types of health care providers. Although obstetric practitioners report fetal deaths, certain situations can occur during a delivery in which viability or possibility of survival is unclear; the pediatrician or neonatologist may attend the delivery An analysis of expulsion of a fetus assess the medical condition of the fetus or infant, assess previable gestational age, provide care as indicated, and report a subsequent infant death, if it occurs.

Incorrectly defining and reporting fetal deaths and early infant deaths may contribute to misclassification of these important events and result in inaccurate fetal and infant mortality rates. This role includes making the determination of the specific vital event during delivery, recording information surrounding the event on the appropriate certificate or report in compliance with state-specific requirements, and ensuring completeness and accuracy of the information, including the underlying cause of death when known.

Although guidance for these definitions is provided elsewhere, 4—6 it may not be readily available to pediatricians in the delivery room. Both the collection and use of information about fetal, infant, and perinatal deaths have been hampered by lack of understanding of differences in definitions, statistical tabulations, and reporting requirements among providers and state, national, and international bodies.

Distinctions can and should be made between the definition of an event and the reporting requirements for the event. The definition indicates the meaning of a term eg, live birth, fetal death.

A reporting requirement is that part of the defined event for which reporting is mandatory.

An infant is live born and younger than days of age. Challenges in consistent definitions of fetal and infant death mostly stem from perception of viability, which should not change the definition of the event. On the basis of international standards set by the World Health Organization, 7 the National Center for Health Statistics of the Centers for Disease Control and Prevention defines live birth, fetal death, infant death, and perinatal death as follows.

Heartbeats are to be distinguished from transient cardiac contractions; respirations are to be distinguished from fleeting respiratory efforts or gasps.

Fetal Death Death before the complete expulsion or extraction from the mother of a product of human conception, irrespective of the duration of pregnancy, that is not an induced termination of pregnancy.

The death is indicated by the fact that, after such expulsion or extraction, the fetus does not breathe or show any other evidence of life such as beating of the heart, pulsation of the umbilical cord, or definite movement of voluntary muscles.


Perinatal Death Perinatal death is not a reportable vital event, per se, but is used for statistical purposes. Perinatal deaths refer to fetal deaths and live births with only brief survival days or weeks and are grouped on the assumption that similar factors are associated with these losses.

Three definitions of perinatal deaths are in use: Perinatal death, definition I, includes infant deaths that occur at less than 7 days of age and fetal deaths with a stated or presumed period of gestation of 28 weeks or more.

Perinatal death, definition II, includes infant deaths that occur at less than 28 days of age and fetal deaths with a stated or presumed period of gestation of 20 weeks or more.

Perinatal death, definition III, includes infant deaths that occur at less than 7 days of age and fetal deaths with a stated or presumed gestation of 20 weeks or more. From national and international perspectives, perinatal deaths have important implications for both public health and clinical interventions.Childbirth, also known as confinement, labour and delivery, is the ending of a pregnancy by one or more babies leaving a woman's uterus by vaginal passage or Caesarean section.

In , there were about million births globally. About 15 million were born before 37 weeks of gestation, while between 3 and 12% were born after 42 weeks. In the developed world most deliveries occur in hospital. The expulsion of a mature ovum from an ovary is called.

ovulation. Fertilization normally takes place in the The membranous bag that surrounds the fetus before delivery is called the. amniotic sac.

The combining form gravid/o is defined as Down syndrome was diagnosed prenatally by laboratory analysis of the amniotic fluid obtained by. In these cases, the concentration of putrefaction gases in the abdomen provides a pressure on the uterus, which can lead to an expulsion of the previously in utero embryo/fetus.

A seat-position of the fetus can then lead to a retention of the head and its natural dismemberment. Abortion is the expulsion or extraction from its mother of an embryo or fetus weighing grams or less when it is not capable of independent survival at or before 22 weeks of gestation.
