Objective To investigate the therapeutic effect of goal-directed fluid therapy on perioperative volume therapy in patients with placenta previa during perioperative period. Methods Eighty patients undergoing cesarean section were randomly divided into 2 groups(n=40 in each group):the conventional therapy group(N group)and the target management of resuscitation group(G group). Patients in G group were connected the Flo-Trac/Vigileo monitoring system to obtain the information of△SV and CI which were used to guide goal-directed flu-id therapy. Hemodynamics,blood coagulation indexes and lactic acid content in different periods of operation were recorded. Results Compared with N group,colloid infusion volume,HR,△SV,the amount of phenylephrine, PT,APTT and TT were decreased,but urine volume,CVP,CI and MBP of each time point and FIB were mark-edly increased(P < 0.05,respectively). Conclusion The application of FloTrac/Vigileo monitoring system for goal-directed fluid therapy,real-time monitor and effectively maintain hemodynamics in patients with dangerous placenta previa during perioperative period,which can improve the postoperative coagulation function and is better than the conventional rehydration capacity.
