体位变化对脑室引流术患者颅内压和平均动脉压及脑灌注压的影响

目的 探讨脑室引流患者的体位变化对平均动脉压、颅内压和脑灌注压的影响.方法 对60例接受过脑室穿刺术并留置脑室引流管患者,监测其抬高床头0°、15°、30°、45°时的颅内压(ICP)和平均动脉压(MAP),再计算出脑灌注压(CPP),比较不同体位状态下患者的MAP、ICP和CPP.结果 ICP随着床头的抬高而显著降低...

Relation of position change to patients'intracranial pressure, cerebral perfusion pressure and mean arterial pressure after ventricle puncture and drainage

Objective To investigate the relation of position changes to patients′intracranial pressure(ICP),cerebral perfusion pressure(CPP)and mean arterial pressure(MAP).Methods Totally,60 patients who were treated by ventricle puncture and drainage therapy were recruited into the research.We monitored their ICP and MAP when the head of bed was raised from 0°to 15°,30°,and 45°,and then we calculated the CPP at different angles.Results ICP was significantly decreased as the head of bed was elevated(P<0.01 for all).CPP at 0° head of bed position had significant differences with CPP at 30°,or 45°head of bed positions;CPP at 15° head of bed position had significant difference with CPP at 45°(P<0.01 for all).Conclusions The 30° head of bed position for paients after ventrical puncture and drainage can decreased ICP significantly and maintain stable CPP.
