Inclusion Criteria13

• Neonates born at ≥ 36 0/7 weeks
• Mild Encephalopathy on neonatal neurologic exam within 6 hours after birth: defined as presence of at least 2 signs of mild, moderate, or severe encephalopathy with no more than 2 signs in the moderate or severe category.
• Perinatal Acidosis based on at least one of the following (A or B):
• pH ≤ 7.00 in any cord or first infant gas (arterial, venous, or capillary) within ≤ 60 min OR base deficit ≥ 16 in any cord or first infant gas (arterial, venous or capillary) within ≤ 60 min
• If pH is between 7.01 and 7.15, OR base deficit is between 10 and 15.9 mmol/liter, OR blood gas is not available, an acute perinatal event is an additional criteria required (see below definition)
• An acute perinatal event is defined by at least one of the following:
• Apgar score at 10 min ≤ 5
• Continued need for resuscitation at 10 min (chest compressions, bag mask ventilation, or positive pressure ventilation)
• Uterine rupture, placental abruption, cord accident (prolapse, rupture, knot or tight nuchal cord)
• maternal trauma, maternal hemorrhage, or cardiorespiratory arrest
• fetal exsanguination from either vasa previa or feto-maternal hemorrhage, shoulder dystocia
• Any evidence suggestive of acute perinatal event.
• Infants are still eligible for enrollment in the COOLPRIME study if the cord or infant's first blood gas (arterial, venous, or capillary) is obtained \>60 minutes of life.
