Integrative Therapy. They fall into three groups:. However, there is a difference in meaning [ 2 ] :. A baby may not be SGA but may still be considered to have had IUGR if they have features of in-utero growth restriction and malnutrition at the time of birth.
Therefore, neonates with a birth weight less than the 10th percentile will be SGA but not an IUGR if there are no features of malnutrition. A neonate with a birth weight greater than the 10th percentile will be an IUGR, in spite of not being SGA, if the infants have features of malnutrition at birth. Maternal factors can affect placental transfer of nutrients - eg, low pre-pregnancy weight, under-nutrition, substance abuse or severe anaemia.
Medical conditions can affect placental implantation and vasculature and hence transfer - eg, pre-eclampsia, autoimmune disease, thrombophilias, renal disease, diabetes and essential hypertension. See also separate Intrauterine Growth Restriction article for more information. Risk assessment must always be individualised, taking into account previous medical and obstetric history and current pregnancy history.
Fetal echogenic bowel has been shown to be independently associated with an SGA neonate and fetal demise. A review found that effective interventions are available for reducing the occurrence of SGA fetuses and preventing related perinatal mortality. Some interventions are effective in all women, while others target specific comorbidities. The most effective interventions to prevent the SGA fetus were antiplatelet agents like aspirin before 16 weeks in women at risk of pre-eclampsia, and progesterone therapy for prevention of preterm birth.
For the prevention of perinatal mortality in high-risk women, antiplatelets and antenatal corticosteroids were found to be effective interventions [ 3 ].
Preeclampsia Preeclampsia and Eclampsia Preeclampsia is new high blood pressure or worsening of existing high blood pressure that is accompanied by excess protein in the urine and that develops after the 20th week of pregnancy. Early separation of the placenta placental abruption Placental Abruption Placental abruption is the premature detachment of a normally positioned placenta from the wall of the uterus, usually after 20 weeks of pregnancy.
If these women get enough sleep and take antiseizure drugs Birth defects Overview of Birth Defects Birth defects, also called congenital anomalies, are physical abnormalities that occur before a baby is born.
They are usually obvious within the first year of life. The cause of many birth Typical symptoms include intellectual disability, paralysis, incontinence, or loss of sensation in some Some are severe, but many are not. Defects may involve abnormal formation of the heart's walls or valves or of the blood vessels that enter These defects are not usually apparent at the doctor's examination Certain infections in the fetus, including Zika virus Zika Virus Infection Zika virus infection is a mosquito-borne viral infection that typically causes no symptoms but can cause fever, rash, joint pain, or infection of the membrane that covers the white of the eye Genetic abnormalities Gene abnormalities Chromosomes are structures within cells that contain a person's genes.
A gene is a segment of deoxyribonucleic acid DNA and contains the code for a specific protein that functions in one or Trisomy 18 caused by an extra chromosome Despite their size, small-for-gestational-age newborns usually look and act similar to normal-sized newborns of similar gestational age.
Some small-for-gestational-age newborns appear thin and have less muscle mass and fat, and some have sunken facial features called wizened facies. The umbilical cord can appear thin and small. During pregnancy, growth-restricted fetuses are at increased risk of miscarriage Miscarriage A miscarriage is the loss of a fetus due to natural causes before 20 weeks of pregnancy. Miscarriages may occur because of a problem in the fetus such as a genetic disorder or birth defect Pregnancy complications are problems that occur only during pregnancy.
They may affect the woman, the fetus, or both and may occur At birth, small-for-gestational-age newborns who are born full term do not have the complications related to organ system immaturity that premature newborns of similar size have. They are, however, at increased risk of the following problems:. Perinatal asphyxia Perinatal asphyxia Birth injury is damage that occurs as a result of physical pressure during the birthing process, usually during transit through the birth canal.
Many newborns have minor injuries during birth It may result from a problem with the placenta before or during delivery. Meconium aspiration Meconium Aspiration Syndrome Meconium aspiration syndrome is trouble breathing respiratory distress in a newborn who has breathed aspirated a dark green, sterile fecal material called meconium into the lungs before Low blood sugar glucose levels hypoglycemia Hypoglycemia Hypoglycemia is abnormally low levels of sugar glucose in the blood.
Hypoglycemia is most often caused by drugs taken to control diabetes. Much less common causes of hypoglycemia include other Doppler flow. This test uses sound waves to measure blood flow. Small weight gain may mean a smaller baby.
Gestational assessment. Babies are weighed in the first few hours after birth. A baby with SGA may be weak and less able to feed as well, or to stay warm.
He or she may be put in a temperature-controlled bed or incubator to keep warm. Tube feedings may be done to make sure the baby has enough nutrition. Blood tests may be done to check blood sugar levels. And blood oxygen levels will be watched. If needed, extra oxygen or mechanical ventilation may be used to help the baby breathe. Prenatal care is important in pregnancy. Stopping use of tobacco, alcohol, and drugs is important for a healthy pregnancy.
