严重脑外伤后颅内压变化及其对预后的意义

Intracranial Pressure and Outcome after Severe Head Injuries

对48例严重闭合性颅脑损伤病人进行持续颅内压监测。结果表明,严重颅脑损伤后的早期常出现颅内压增高,多数病人颅内压增高是在伤后或术后12小时内开始,在48小时内达到高峰,颅内压增高持续6天以内。当颅内压>5.3kPa(40mmHg)时预后不良。

Forty-eight patients with acute severe head injuaies underwent continuously intracranial pressure monitoring. The results showed that in most of cases increased intracranial pressure occurred at the acute stage after head injury. Raised intracranial paessure occurred within 12 hours after injury in more than half of the cases. The time of highest intracranial pressure peak was found within 48 hours and increased intracranial pressure continued for six days in most of the cases. The prognosis was very grave when the intracranial pressure raised over 5.3kPa(40mmHg).
