Feasibility and Safety of Therapeutic Hypothermia and Short Term Outcome in Neonates with Hypoxic Ischemic Encephalopathy.

Therapeutic hypothermia is well known for neuroprotection in asphyxiated neonates with hypoxic ischemic encephalopathy. The authors aimed to study the feasibility and safety of therapeutic hypothermia and short term outcome in neonates with hypoxic ischemic encephalopathy (HIE). Total 31 neonates with moderate to severe HIE were enrolled in the study. Continuous temperature recording was noted in 31 neonates; 17 neonates were studied prospectively while 14 neonates were studied retrospectively. Rectal temperature was monitored in 31 neonates and maintained between 33 and 34 °C by switching off the warmer and using ice packs. Reusable ice packs were used which were inexpensive. Therapeutic hypothermia was maintained for 72 h and babies were then rewarmed 0.5 °C every hour. Therapeutic hypothermia was feasible and inexpensive. There was no major complication during the study. MRI was done in 17 neonates; 52 % were found to have normal MRI at the end of first week. Among the study neonates (n = 31) 64.5 % were neurologically normal at the time of discharge. To conclude, therapeutic hypothermia is feasible in a low resource setting and is a safe way of neuroprotection. Short term outcome was also favourable in these neonates.
