To assess the feasibility of intra-operative autotransfusion (IAT) as a method of decreasing or avoiding homologous blood transfusion during radical cystectomy.
IAT was performed in 10 patients with bladder cancer who underwent radical cystectomy. The patients were divided into two groups: group 1 consisted of six patients without and group 2 of four patients with pre-deposited blood. Blood shed in the operative field was collected and processed with an IAT device.
In group 1, the intra-operative blood loss ranged from 1.08 to 2.67 L (mean 1.82) and homologous blood transfusion ranged from 0 to 1 L (mean 0.47). The amount of autologous blood processed and transfused by the IAT device ranged from 0.38 to 0.98 L (mean 0.64). Two patients did not require homologous blood transfusion. In group 2, the volume of pre-deposited blood ranged from 0.8 to 1.2 L (mean 0.9). The intra-operative blood loss ranged from 1.03 to 3.24 L (mean 1.8). The amount of processed autologous blood transfused ranged from 0.4 to 0.6 L (mean 0.45). None of the patients in group 2 required homologous blood transfusion.
Although there are theoretical risks with IAT, they were not substantiated by the clinical data. IAT seems to be a feasible method of reducing or avoiding homologous blood transfusion in radical cystectomy. These results suggest that IAT in combination with pre-deposited blood will abolish the need for homologous blood transfusion during radical cystectomy.
评估术中自体输血(IAT)作为一种在根治性膀胱切除术中减少或避免异体输血方法的可行性。
对10例行根治性膀胱切除术的膀胱癌患者进行术中自体输血。患者分为两组:第1组6例患者未进行术前储血,第2组4例患者进行了术前储血。收集手术野中流出的血液并用术中自体输血装置进行处理。
第1组术中失血量为1.08至2.67升(平均1.82升),异体输血量为0至1升(平均0.47升)。术中自体输血装置处理和输注的自体血量为0.38至0.98升(平均0.64升)。2例患者无需异体输血。第2组术前储血量为0.8至1.2升(平均0.9升)。术中失血量为1.03至3.24升(平均1.8升)。处理后输注的自体血量为0.4至0.6升(平均0.45升)。第2组患者均无需异体输血。
虽然术中自体输血存在理论风险,但临床数据并未证实这些风险。术中自体输血似乎是一种在根治性膀胱切除术中减少或避免异体输血的可行方法。这些结果表明,术中自体输血与术前储血相结合将消除根治性膀胱切除术中异体输血的需求。
