Abstract: Objective:To study the clinical effectiveness of acute hypervolemic hemodilution (AHH) combined with controlled hypotension (CH) in the repair of traumatic superior sagittal sinus rupture.Methods:42 patients,ASAⅡ～Ⅲ,undergoing the repair of superior sagittal sinus rupture under general anesthesia,were randomly divided into two groups,group I AHH+CH and groupⅡAHH.MAP,HR,CVP,Hb and Hct were recorded respectively before AHH(T0)，at the beginning of skull enclosed (T1)，10 min after skull enclosed (T2)，at the end of superior sagital sinus rupture (T3) and at the end of operation (T4)，bleeding volume，urine volume，blood infusion volume，total liquid infusion volume and liquid infusion volume during AHH were calculated.Results:CVP significantly increased at T1 compared with T0 in both groups;CVP at T2 and T3 compared with at T0,there was no remarkable difference in group I,but CVP significantly decreased in groupⅡ,and CVP in groupⅡ were lower significantly than those of group I at T2 and T3.Liquid infusion volume during AHH was more and blood infusion volume was less in group I than that in groupⅡ.Conclusion:It is safe that acute hypervolemic hemodilution combined with controlled hypotension was applied to the repair of traumatic superior sagittal sinus rupture;it can significantly increase liquid infusion volume during AHH,improve stability of hemodynamics,and decrease blood infusion volume.
