Result: The incidence of lung infection of very severe head injury is 82% . severe head injury 40%, moderatehead injury 3 % . The difference were of statistically significant (P<0.01 ).
OBJECTIVE to observe the effect of technology of cerebral protection of moderate hypothermia antegrade selective cerebral perfusion (ASCP) or circulatory arrest (CA) with ice-bag under the head.
Conclusion Moderate hypothermia can obviously reduce ICP and improve brain tissue oxygen metabolism to lower the morbidity and mortality rate of severe head injury.
