Effect of different positions on the ICP,CPP and vital signs in patients with cerebral hemorrhage

Objective:To investigate the effects of different positions on the ICP,CPP and vital signs in patients with cerebral hemorrhage.Methods:The ICP,CPP,cerebral tissue oxygen saturation(rSO₂) and vital signs in 46 hypertension patients with cerebral hemorrhage were monitored at 0°,15°,30° and 45° of bed head.Results:With the elevating of bed head angle,the ICP and CPP value of patients gradually decreased,and the difference of those in different groups were statistically significant(P<0.01 and P<0.05).The results of pairwise comparison showed that the ICP value at 15°,30° and 45° of bed head significantly decreased compared with the 0° of bed head,the ICP value at 30° and 45° of bed head was lower than that at 15° of bed head(P<0.05),and the CPP value at 45° of bed head was higher than that at 0° of bed head(P<0.05).The differences of the rSO₂,pulse oxygen saturation,heart rate,systolic pressure,diastolic pressure,mean arterial pressure and body temperature between different angles were not statistically significant(P>0.05).At different angles of bed head,the rSO₂ was positively correlated with mean arterial pressure and ICP(P<0.05),and negatively correlated with the CPP(P<0.05).Conclusions:Within the 15° to 30° of bed head,the nursing effect of patients is the best.
