Abstract
Recent research using newborn animal models of hypoxia-ischaemia has shown that cooling the subject from 3 to 6 degrees C starting after the insult and lasting up to 72 h offers long-lasting neuroprotection. One concern is that additional stress during hypothermia seems to reduce the beneficial effect. Phase 1 studies on cooling severely asphyxiated infants have not yet revealed any systemic adverse effects. The evidence is strongly in favor of hypothermia reducing brain damage after asphyxia and the time has come for undertaking randomized trials.
