Systemic hypothermia after neonatal encephalopathy: outcomes of RCT.

Study aim and design

Newborn infants with a gestational age of > 36 weeks , asphyxiated at birth, who show evidence of encephalopathy and who have abnormal EEG within 6 hrs of postnatal age, have been randomized to hypothermia or to normothermia. Hypothermia (target rectal tem­perature 33.5°C) was induced by using a cooling matters, perfused with water. Hypother­mia was maintained for 72 hours. Infants in both groups received morphine at a seda­tive and analgesic dosage.


Study group

Participants in Germany and other European Countries within the framework of the ”neo-nEuro-network” (abbreviated n.n.n), an non-juridal association of neonatologists interested in neurological and neuro-intensive care investigations.

We thank the principal investigator Peter D Gluckman, Auckland, New Zealand of the Olympic Medical Brain Cooling Trial and Olympic Medical for providing a copy of that protocol. Inclusion and exclusion criteria and the primary endpoint were identical in the two protocols. The brain cooling trial used a cooling cap and a target body temperature of 34.5°C whereas we used systemic cooling to 33.5°C and all patients received mor­phine for pain and sedation. We also thank Professors Azzopardi D and Edwards DA for providing insight into their study protocol.
