A newborn in California recently received the benefits of an innovative therapy that cools the baby’s body to decrease brain injury. This therapy helps minimize birth-related brain injuries that can cause cerebral palsy, neurological problems and other cognitive delays.
The California newborn had been cut off from oxygen and was beginning to swell after his birth. There is only a small window of opportunity in which the therapy can be beneficiation. Doctors had around six hours to drop the baby’s body temperature to 92.3 degrees, about 6 degrees below normal.

Lower body temperatures have long been known to minimize brain injury. However, doctors have debated about the best method in which to lower a baby’s temperature. Since speed is a critical factor in the therapy’s success, the hospital used a whole-body cooling blanket designed for newborns deprived of oxygen. The blanket system is designed to quickly induce whole-body hypothermia.
A lack of oxygen to the brain causes hypoxic-ischemic encephalopathy. When this occurs the brain reacts to the lack of oxygen by swelling. The swelling then cuts off blood supply to the brain. As the body tries to protect the brain other organs such as the kidneys and liver can be damaged as well.
It is important to quickly cool the body in order to prevent damage because the swelling in the brain occurs over several hours before the damage becomes permanent. Lowering the body’s temperature lowers the body’s metabolism, hearth rate, and blood pressure. As a result, the swelling in the brain is reduced.
