What is cooling therapy for babies?
Neonatal Whole Body Cooling Procedure. Some newborns experience hypoxic ischemic encephalopathy (HIE) at birth. This abnormal neurological state results from reduced levels of oxygen (hypoxia) or blood flow (ischemia) to the baby's brain or body. Over the past several years, therapeutic hypothermia, or whole body cooling, has been used to treat HIE.

(Core temperature is monitored continuously using esophageal or rectal temperature probe) [ Figure 1 ]. Figure 1 Flow chart for commencing therapeutic hypothermia
Why would a newborn need to be cooled?
Total body cooling (or whole-body hypothermia) is a process where the baby's temperature is carefully lowered after a traumatic labor experience. Essentially, we're protecting the brain by minimizing the production of toxic substances that can cause brain injury.Jul 23, 2019
Why do babies get cooled in NICU?
Neonatal body cooling, also called newborn therapeutic hypothermia, lowers your baby's body temperature to treat hypoxic ischemic encephalopathy (HIE). HIE is a neonatal brain injury that occurs if your baby's brain doesn't receive enough oxygen.
What does cooling mean for a baby?
Cooling therapy, also called neonatal or therapeutic hypothermia, is one of the most effective treatments for HIE when administered properly. Cooling the baby's body and brain temperature in a controlled environment alters chemical processes in the brain, thus reducing the risk of permanent brain damage.Jul 20, 2021
What is cooling therapy used for?
Once the heart starts beating again, healthcare providers use cooling devices to lower your body temperature for a short time. It's lowered to around 89°F to 93°F (32°C to 34°C). The treatment usually lasts about 24 hours. The heart has an electrical signal that helps coordinate the heartbeat.
When should I start cooling therapy?
According to the Academic Medical Center Patient Safety Organization (AMC PSO), hypothermia therapy should ideally be commenced within six hours of birth (under certain circumstances, this may be done within 12 hours) (2).
How effective is HIE cooling?
There is now good scientific evidence that cooling a baby with moderate or severe HIE to a temperature of 33-34°C, can help to reduce the severity of the injury to the brain and improve the longer term outcome for the baby. There is also some evidence that the faster the baby is treated, the better the outcome.
What is head cooling in newborns?
Neonatal head cooling is a somewhat new treatment through which doctors cool a newborn's head immediately after a traumatic delivery. If a baby experienced a lack of oxygen during birth, otherwise known as hypoxic ischemic encephalopathy (HIE) caused by asphyxia, the brain can experience irreversible damage.
Do babies recover from HIE?
Most babies with mild HIE recover quickly. If your baby has mild HIE, doctors will monitor them closely to check that they are stable and do not need any more treatment. If your baby has moderate to severe HIE, there is a risk of death or long-lasting damage to the brain.
What is HIE newborn?
Hypoxic ischemic encephalopathy (HIE) is a type of brain dysfunction that occurs when the brain doesn't receive enough oxygen or blood flow for a period of time. Hypoxic means not enough oxygen; ischemic means not enough blood flow; and encephalopathy means brain disorder.
What is the reason for body cooling?
A brain region called the hypothalamus is responsible for regulating body temperature. It checks the body's current temperature against its normal temperature and then regulates it. When the body is too hot, regulation occurs through sweating to cool it down.
How long does it take for a baby to cool down?
We continuously monitor your baby during the body cooling process to ensure that he or she receives excellent care. After three days of cooling, your baby will be slowly warmed to normal body temperature. Procedures your baby may need during treatment include:
What to do after NICU discharge?
Once discharged from the NICU, your baby will need careful follow-up with your pediatrician. Additional appointments may be needed with specialists such as a developmental psychologist or neurologist. Call 703-776-6020 for more information about the neonatal whole body cooling procedure at Inova Children's Hospital.
What tests are used to diagnose a baby with HIE?

Some newborns experience hypoxic ischemic encephalopathy (HIE) at birth. This abnormal neurological state results from reduced levels of oxygen (hypoxia) or blood flow (ischemia) to the baby's brain or body. Over the past several years, therapeutic hypothermia, or whole body cooling, has been used to treat HIE.
How long does it take for a baby to get a temperature of 92 degrees Fahrenheit?
Your baby's temperature will be lowered, slowly and safely, to 92 degrees Fahrenheit (33.5 degrees Celsius). By maintaining this temperature for three days, your baby's metabolic processes slow. This decreases the severity and extent of potential brain injury from HIE.

Why is it important to cool a baby?
Cooling babies 'helps reduce longer-term brain damage'. Cooling babies deprived of oxygen at birth improves their chances of growing up without disabilities such as cerebral palsy, research suggests. The New England Journal of Medicine study showed newborns given the treatment were more likely to have higher IQs at school age.
How does cooling help the brain?
Researchers think the therapy works by slowing the production of harmful substances in the brain and the rate of brain cell death.
Why are babies put on a mat?
Babies were placed on a special mat and cooled at 33C for three days to help reduce brain injury. Experts say the study confirms the therapy has long-lasting effects. Around one in 500 newborns in the UK suffer from asphyxia - a lack of oxygen around the time of birth.
What percentage of children have no brain abnormalities?
About 45% of cooled children had no brain abnormalities, compared with 28% of those who had had standard treatment. And some 21% in the cooling group had cerebral palsy, compared with 36% in the control group. Babies in the hypothermia group were also more likely to have IQ scores above 85.
What is the IQ of a baby with hypothermia?
Babies in the hypothermia group were also more likely to have IQ scores above 85 . Lead author Prof David Edwards, of King's College London, told the BBC: "What is remarkable about this study is that 20 years ago people thought nothing could be done for this group of patients who can suffer devastating brain damage.
Does cooling help with survival?
The cooling treatment showed no influence on survival rates though - a similar proportion (about 30%) of babies in both groups did not survive to school age. Researchers say the next steps will be to look at therapies that can work in conjunction with therapeutic hypothermia and increase the chances of normal survival.
Does cooling babies help them grow up?
Cooling babies deprived of oxygen at birth improves their chances of growing up without disabilities such as cerebral palsy, research suggests. The New England Journal of Medicine study showed newborns given the treatment were more likely to have higher IQs at school age.
How long does it take for a baby to cool down?
The goal is to start cooling within six hours of birth – the sooner the better. We place the baby on a special blanket that circulates water through it, which cools and eventually warms the baby. Then we place a small temperature probe in the baby’s esophagus to track his or her core temperature.
What does a neonatologist do after stabilizing a newborn?

Low Apgar scores that persist longer than 10 minutes.
What happens if the umbilical cord breaks during labor?
Umbilical cord prolapse : When the bag of water breaks at the onset of labor, the umbilical cord can slip through the partially dilated cervix. If the cord is squeezed between the baby’s and mother’s bodies, the baby might not receive enough blood and oxygen. In spontaneous labor, we can’t plan for the water breaking.
How many deliveries does umbilical cord prolapse?
Umbilical cord prolapse occurs in 1 to 6 of 1,000 deliveries. Amniotic fluid embolism : If amniotic fluid enters a patient’s bloodstream, she can go into shock, essentially causing respiratory failure, cardiovascular collapse, and heavy bleeding.
