Objective To investigate the safety of popularizing the acute hypervolemic hemodilution (AHH) under noninvasive wardship condition.Methods 120 patients were divided into three groups by double blind method.The group A was simple AHH,group B was AHH plus controlled hypertension (CH),and group C was the routine treatment one.The multi function wardship instrument was used to observe ECG and BP and SpO 2 etc.,and Hct and HGB was examined at different times,before anesthesia allurement,after the beginning of operation and 72 hours after operation.The RPP (the product of HP and BP) and the viaration value of ECG ST and urine volume and SpO 2 were recorded at the same time.The hemorrhage and blood transfusion amount was calculated after operation according to the measurement of the blood in inhaled bottle,the weight of pledget and the record of the transfusion amount.Results The RPP of group B was significantly lower after hypervolemic hemodilution (P0.01),while the other two groups increased significantly and there were significant differences among groups (P0.01).The values of Hct and HGB of group A and groups B after the beginning of operation were significantly decreased,as compared with that of group C (P0.01),so that the AHH and the urine volume of group A after operation was significantly increased,as compared with those of the other two groups (P0.01).Although the hemorrhage amount in operation among groups had no significant difference,the blood transfusion amount in operation of group A was significantly lower than those of the other two groups (P0.01),and the values of Hct and Hb were higher than those of the other two groups.Conclusion It is safe to use acute hypervolemic hemodilution under noninvasive wardship condition to protect blood and the AHH plus CH scheme is the best measure.
