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.
The most common definition of intrauterine growth restriction (IUGR) is a fetal weight that is below the 10th percentile for gestational age as determined through an ultrasound. This can also be called small-for gestational age (SGA) or fetal growth restriction. There are basically two different types of IUGR: Symmetric or primary IUGR is characterized by all internal organs being reduced in size. Symmetric IUGR accounts for 20% to 25% of all cases of IUGR.
