Abstract:
Objective To compare the effects of volume preloading with crystalloid and colloid fluid to prevent hypotension associated with thoracic epidural block combined general anesthesia.Methods Ninety ASA Ⅰ～Ⅱ grade patients,scheduled for elective upper abdominal surgery,were randomly allocated to three groups(30 patients in each group).A,B and C group respectively received 1000ml lactated Ringer's solution,500ml and 1000ml polygeline injection for volume preloading in 40min before general anesthesia induction.During volume preloading,epidural catheter was placed at T_ 8～9 and blocked with mixed solution of 1.6% lidocaine and 0.2% dicaine.Results Systolic blood pressure(SBP) and diastolic blood pressure(DBP) were significantly lower in group A and B than those in group C after epidural block,general anesthesia induction and intubation(P
