不同液体术前急性高容量血液稀释对深静脉血栓病人血液流变学的影响

Objective To investigate the effects of acute hypervolemic hemodilution (AHH) with different fluids on blood rheology in patients with deep vein (femoral and iliac) thrombosis. Methods Thirty ASA I or II patients aged 40-64 yr who had developed deep vein thrombosis in 48 h and were scheduled for embolectomy were randomly divided into 3 groups ( n = 10 each) ; group I normal saline (NS) ; group II 6 % HES 200/0.5 ( HES) ; group IE gelofusine (GEL). AHH was performed with normal saline, 6% HES or gelofusine infusion at 20 ml·kg-1 ·h-1 for 40 min. MAP, HR and SpO2 were monitored. Blood loss, volume of blood transfusion and fluid infused and urine output during operation were recorded. Anesthesia was induced with fentanyl 3-5 fig/kg, etomidate 0.15-0.30 mg/kg, propofol 1-2 mg/kg and succinylcholine 1-2 mg/kg and maintained with 2% isoflurane and propofol infusion at 5-8 mg·kg-1·h-1 and intermittent iv boluses of vecuronium. The patients were mechanically ventilated (VT 8 ml/kg, RR 12 bpm). PaO2 and PaCO2 were maintained within normal range. Venous blood samples were obtained before and after AHH for measurement of hematocrit (Hct), whole blood viscocity (WBV) at low or high shear rates, plasma viscosity, RBC aggregation and RBC deformation. RBC aggregation index and RBC deformation index were calculated. Results MAP and HR were stable in all patients. The amount of blood transfusion and fluid infused was significantly less in group HES and GEL than in group NS. The WBV at low or high shear rates in group HES and GEL, Hct in all 3 groups and RBC aggregation index in group HES were significantly decreased after AHH, but the RBC deformation index was significantly increased in group HES. Conclusion Colloid is better than crystalloid and HES is better than gelofusine in improving intraoperative hypercoagulability and sluggish blood flow.

体外循环对TXB2／6—keto—PGF1α的影响

对１３例体外循环病人进行了观察，发现体外循环后ＴＸＢ２／６－ｋｅｔｏ－ＰＧＦ１α显著增高，表明体外循环使血小板受损，而血小板受损是体外循环后失血的主要原因之一。     

HPLC测定盐酸丁卡因注射液含量

 本文报道用HPLC法测定盐酸丁卡因注射液的含量，并同时测定分解产物对丁氨基苯甲酸 的含量。采用ODS柱,流动相为甲醇-0. 0275mo1/L磷酸二氢钠(85：15),以磷酸调pH为4.5,流速 lml/min,以对氨基苯磺酸为内标，检测波长为3OOnm。酸丁卡因线性范围为0.1-1.0μg，回收率为 98.99％，RSD=1.0l％；对丁氨基苯甲酸线性范围为0.0005-0.005μg,回收率为98.18％，RSD= 1.81％(n＝3)。
