Abstract：Objective To explore the influence of posture nursing on intracranial pressure(ICP),mean arterial pressure (MAP)and cerebral perfusion pressure(CPP)in patients with severe conditions undergone craniotomy.Methods A total of 40 patients with severe craniocerebral injury who were provided with craniotomy from March 2015 to February 2016 were selected.All patients were nursed in 0°,10°,20°,30°and 40°postures.The ICP,MAP and CPP were compared in different positions,and the correlation analysis was performed.Results The level of ICP was gradually decreased ranging from 0°to 40°with statistical differences(P＜0.05).The MAP level was also decreased gradually at 0°to 40°,which was displayed statistical differences(P＜0.05).The levels of CPP was(69.7±5.5),(70.2±4.4),(71.1±3.9),(74.5±3.6)mmHg were gradually increased at 0°to 30°.At 40°,the level of CPP was（63.5±3.5）mmHg,significantly lower than those at 0°to 30°with statistical differences(t=6.015,P=0.000;t=7.537,P=0.000;t=9.173,P=0.000;t=13.856,P=0.000).By correlation analysis,posture was in great negative correlation with ICP and MAP in patients with critical conditions after craniotomy (r=0.732,P=0.000;r=0.757,P=0.000).Conclusion Posture nursing has a certain influence on the levels of ICP,MAP,and CPP in patients with critical conditions undergone craniotomy.Among them,posture at 30°to 40°,the levels of ICP and MAP are both decreased,and CPP is in rise simultaneously,which is beneficial to patient′s prognosis.
