Abstract:
Objective To investigate the effect of hydroxyl starch (HES 200/0 5) infusion on blood rheology during operation Methods Forty adult ASA Ⅰ Ⅱ patients (male 28, female 12) scheduled for elective operation on spine (26 patients) and lower extremities (14 patients) were enrolled in this study The age ranged from 18 56 yr and weight from 40 85kg Preoperative heart, lung, liver and kidney function tests, blood routine exam, bleeding and coagulation time were all normal No patients had any history of abnormal bleeding The patients were randomly divided into two equal groups: control group(C) receiving lactated Ringer solution 1 000ml during operation and HES group receiving 6% HES 1 000ml No patient received any plasma or whole blood during operation The patients were premedicated with intramuscular atropine 0 5mg and sodium luminal 0 1g The operations were all performed under continuous epidural block (1 6% lidocaine with adrenaline 1:200 000) BP,ECG,and SpO 2 were continuously monitored during operation Blood pressure was maintained with range and SpO 2 above 97% Venuos blood samples were taken before anesthesia , 30min and 4h after the fluid had been infused and 24h after operation for determination of blood viscosity, plasma viscosity, hematocrit(HCT) index of red blood cell (RBC) aggregation and deformation and index of fibrinogen Results Blood viscosity, Hct, index of RBC aggregation and fibrinogen decreased significantly (P
