Methods Thirty patients aged 8-21 yr, undergoing surgical correction of kyphoscoliosis were randomly divided into two groups of fifteen:group A and group B. In group A patients received homologous transfusion during operation, while in group B shed blood was collected from operative field and after filtration RBCs were separated by a differential centrifugation and washed in normal saline and reinfused. Anesthesia was induced with fentanyl 2 μg· kg-1 ,propofol 1 mg·kg-1 and vecuronium 0.1 mg·kg-1 and maintained with inhalation of isoflurane and 50 % N2O in oxygen and intermittent iv boluses of vecuronium and fentanyl. Blood routine, blood gases, electrolytes, plasma osmotic pressure and activated clotting time (ACT) were measured before operation, 2 h after skin incision and at the end of surgery. Blood EPO concentration was measured before operation,at the end展开更多

METHODS: The proportion of patients who received HT was compared between two groups determined by the time of AT introduction; period A (1991-1994, n = 93) and period B (1995-2000, n = 201). Multivariate logistic regression analysis was performed in order to identify independent significant predictors of the need for HT. We also investigated the impact of AT and HT on long-term postoperative outcome after curative surgery for HCC. RESULTS: The proportion of patients with HT was significantly lower in period B than period A (18.9% vs 60.2%, P < 0.0001). Multivariate logistic regression analysis identified AT administration as a significant independent predictor of the need for HT (P < 0.0001). Disease-free survival in patients with AT was comparable to that without any transfusion. Multivariate analysis identified HT administration as an independent significant factor for poorer disease-free survival (P = 0.0380). CONCLUSION: AT administration significantly decreased the need for HT. Considering the postoperative survival disadvantage of HT, AT administration could improve the long-term outcome of HCC patients.展开更多
