Abstract:
Objective To observe the effect of acute hypervolemic hemodilution (AHH) with two kinds of hydroxyethyl starches including Voluven and HES on the renal function of emergency surgery patients with brain injury.Methods This study involved 54 brain injury patients treated with emergency surgery,who were randomly divided into Voluven group ( AHH130 group),HES group ( AHH200 group) and Ringer's lactate group (LR group),with 18 patients in each group.All the patients were managed with inhalation anesthesia.ECG,MAP,CVP and SpO2 were observed in operation.The blood urea nitrogen (BUN),urine creatinine ( BCr,UCr),urinary albumin (ALB) and urinary α1-microglobulin ( α1-MG) were detected before AHH ( T0 ),at the end of operation ( T1 ),at 4 hours ( T2 ),day 1 ( T3 ),day 2 (T4) and day 3 (T5) after operation.The creatinine clearance (CCr) and fractional sodium clearance (FSC) were calculated and the urine output,fluid replacement,blood loss and blood transfusion recorded.Results The HR,CVP and MAP in the three groups were within the normal range of variation at all time points,with statistical difference for comparison between groups and within group ( P ＞ 0.05 ).There was no significant difference in urine output and blood loss,while the intraoperative fluid volume and blood transfusion in the AHH130 group and the AHH200 group were significantly less than those in the LR group (P ＜ 0.01 ).There was no statistical difference in aspects of BUN,BCr and urinary ALB at each time point between and within the three groups ( P ＞ 0.05 ).After treatment with AHH,the urinary α1-MG level in the AHH130 group and AHH200 group was significantly increased ( P ＜0.01 ),which was decreased at T5 but was still higher than that at T0 ( P ＜ 0.01 ),and was higher than that in the LR group at all time points (P＜0.05).After treatment with AHH,CCr was decreased in the AHH130 group and AHH200 group,which reached the lowest level at T2,with statistical difference compared with the levd at T0 ( P ＜0.01 ).Then,CCr was recovered to normal at T5.FSC in the three groups after AHH treatment was increased slightly and the most significantly at T2,which was not statistically different compared with that at T0 ( P ＞ 0.05) and FSC was not statistically different between and within groups at other time points (P ＞0.05).All the values about the renal function in all the groups changed within the normal range at each time point.Conclusions AHH with Voluven or HAES is a feasible and safe blood conservation measure that can significantly reduce the allogeneic blood transfusion but exert insignificant effect on renal function of the brain injury patients with normal renal function before emergency surgery.
