alihu et al., 2003) (Lynch et al., 2007). Assisted Reproductive Technology (ART) is an essential aspect in the occurrence of multiple pregnancies and stillbirth (Helmerhorst et al., 2004).

Complications in Fetus:

Fetal Growth Restriction:

Some stillbirths result from fetuses which are smaller for a particular gestational age (SGA) compared to normal fetuses. Birth weight and risk of stillbirth are inversely proportional. If one increases, the other decreases. The main fact behind stillbirths in this condition is retardation of fetal growth and not the small size of fetus.

An obstacle that occurs in determining the precise time of death of fetus due to SGA is the fact that the death might have occurred a long time before but the gestational age at the time of delivery is considered to be the time of death. This gives a false implication of the magnitude of stillbirths resulting from SGA. This problem can be solved by analysis of early and mid pregnancy placental hormones which are very specific for gestational periods (Smith et al., 2004). An evaluation of the amounts of these hormones relates directly to the time of death.

Umbilical Cord Accidents:

An increased number of stillbirths are due to “accidents” of umbilical cord like cord occlusion or blockage due to true knots, nuchal cords and compression of the cord. In almost 30% of normal healthy infant deliveries, nuchal cord and true knots in umbilical cords are observed.

According to a study in Sweden, 9% of stillbirths were due to cord accidents (Petersson, 2002). Determination of cord accidents leading to fetal death by autopsy is smaller in proportion (up to 2.5%) (Horn et al., 2004). This difference indicates that in the absence of a proper cause, many times fetal death is attributed to cord entanglement.

Due to the increased load of complications with live infants, little concern is expressed towards dead fetuses. In order to precisely relate a fetal death to cord accident, a clear indication of either hypoxic tissue injury or cord occlusion must be observed in autopsy. As nuchal cords are observed in normal deliveries also, the exact proportion of stillbirths due to cord accidents is biased.

Obstetric Complications:

Some of the obstetric complications are preclampsia, preterm premature rupture of membranes, preterm labor, cervical insufficiency, abruption, placenta previa, and vasa previa. These may either be direct or primary causes or may be indirect or secondary causes of stillbirth. Almost 10-19% of stillbirths occur due to abruption. Since cervical insufficiency or preterm labor lead to neonatal death, their role in causing stillbirth is not well defined.

Evaluation of Stillbirth

Stillbirth in itself may be emotionally devastating to many patients and their families. There the likelihood of carrying out genetic testing or autopsy on the fetus may not be readily agreeable from the family and culture. Lastly the procedures for evaluation must be cost effective and within reach. The two important facts that should be kept in mind本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
