Pessary in Singleton Gestations With Short Cervix Without Prior Preterm Birth

2016-03-24 07:23:23 | BioPortfolio


Spontaneous preterm birth (SPTB) remains the number one cause of perinatal mortality in many countries, including the United States. In singleton gestations a short cervical length (CL) on transvaginal ultrasound (TVU) has been shown to be a good predictor of SPTB.

The cervical pessary is a silicone device that has been used to prevent SPTB. The efficacy of cervical pessary has been assessed in several populations including singletons with short CL, unselected twins, twins with a short CL, and triplet pregnancies. Several randomized clinical trials (RCTs) have been published, and several are ongoing. However, no consensus on the use of cervical pessary in pregnancy or guidelines for management have been assessed.

Medical and Biotech [MESH] Definitions

A parameter usually used in PRENATAL ULTRASONOGRAPHY to measure the length of the uterine neck (CERVIX UTERI). Cervical length or its shortening is used to identify and prevent early cervical opening and PRETERM BIRTH.

A network of nerve fibers originating in the upper four cervical spinal cord segments. The cervical plexus distributes cutaneous nerves to parts of the neck, shoulders, and back of the head, and motor fibers to muscles of the cervical spinal column, infrahyoid muscles, and the diaphragm.

Drugs that prevent preterm labor and immature birth by suppressing uterine contractions (TOCOLYSIS). Agents used to delay premature uterine activity include magnesium sulfate, beta-mimetics, oxytocin antagonists, calcium channel inhibitors, and adrenergic beta-receptor agonists. The use of intravenous alcohol as a tocolytic is now obsolete.

Postnatal deaths from BIRTH to 365 days after birth in a given population. Postneonatal mortality represents deaths between 28 days and 365 days after birth (as defined by National Center for Health Statistics). Neonatal mortality represents deaths from birth to 27 days after birth.

Official certifications by a physician recording the individual's birth date, place of birth, parentage and other required identifying data which are filed with the local registrar of vital statistics.
