Associated Press. The fabled tundra of Lambeau Field will be far from frozen when the Green Bay Packers and Minnesota Vikings clash in Saturday's NFC playoff game. Temperatures are expected to be in the teens when the game starts at 7 p.m. Lambeau's underground heating system will keep the turf from freezing. Below the surface, a network of plastic pipes containing antifreeze, covered by a foot of sand, make the field of natural grass and artificial fibers playable.
Mild IUGR usually doesn't cause long-term problems. In fact, most babies with IUGR catch up in height and weight by age 2. But if severe, IUGR can seriously harm a baby before and after birth. The extent of the health problems depends upon the cause and severity of the growth restriction. It also depends upon how far along you are in the pregnancy when it develops.
IUGR has various causes. The most common cause is a problem in the placenta (the tissue that carries food and blood to the baby). Birth defects and genetic disorders can cause IUGR. If the mother has an infection, high blood pressure, is smoking, or drinking too much alcohol or abusing drugs, her baby might have IUGR.UGR usually doesn't occur in another pregnancy. But in some women, it does happen again. Women who have another pregnancy affected by IUGR usually have an illness, such as hypertension, that causes IUGR. Good control of illnesses before and during pregnancy lowers the risk of having another baby with IUGR.
