Intrauterine growth restriction (IUGR), or fetal growth restriction, is the poor growth of a fetus while in the womb during pregnancy. IUGR is defined by clinical features of malnutrition and evidence of reduced growth regardless of an infant's birth weight percentile. [ 5 ]
If small for gestational age babies have been the subject of intrauterine growth restriction, formerly known as intrauterine growth retardation, [5] the term "SGA associated with intrauterine growth restriction" is used. Intrauterine growth restriction refers to a condition in which a fetus is unable to achieve its genetically determined ...
Intrauterine growth restriction may cause or be the result of hypoxia. Intrauterine hypoxia can cause cellular damage that occurs within the central nervous system (the brain and spinal cord). This results in an increased mortality rate, including an increased risk of sudden infant death syndrome (SIDS).
Many factors, including maternal, placental, and fetal factors, contribute to the cause of impaired fetal growth. [23] There are several maternal factors, which include age, nutritional status, alcohol use, smoking, and medical conditions. [23] Insufficient uteroplacental perfusion is an example of a placental factor. [23]
Gestational age at birth is on average shortened by various pregnancy aspects: twin pregnancy, prelabor rupture of (fetal) membranes, pre-eclampsia, eclampsia, intrauterine growth restriction. [29] The ratio between fetal growth rate and uterine size (reflecting uterine distension) is suspected to partially determine the pregnancy length. [30]
This category reflects the organization of International Statistical Classification of Diseases and Related Health Problems, 10th Revision. Generally, diseases outlined within the ICD-10 codes P05-P08 within Chapter XVI: Certain conditions originating in the perinatal period should be included in this category.
Illustration of fundal height at various points during pregnancy. Fundal height, or McDonald's rule, is a measure of the size of the uterus used to assess fetal growth and development during pregnancy. It is measured from the top of the mother's uterus to the top of the mother's pubic symphysis.
“Gravidity” is an important component of a patient’s reproductive history, as it provides insight into the risk factors that the patient has for pregnancy outcomes, such as risk for gestational diabetes, pre-ecclampsia, spontaneous abortion, preterm birth, fetal growth restriction, and more. [5]
