To assess perioperative blood losses and transfusion requirements in patients who undergo breast reduction surgery and to gauge the impact of an autologous blood program on homologous transfusion requirements.
A chart review of patients who underwent breast reduction surgery between 1988 and 1992.
The Ottawa General Hospital, a teaching hospital with a surgical training program but with no plastic surgery program.
Included in the review were all 153 patients who had breast reduction surgery during the study period. Twenty patients were excluded because either the predonation or the final hemoglobin concentration was not available. The remaining 133 patients were divided into three groups: group 1--patients who had not predonated blood (63); group 2--patients who predonated blood and received a transfusion (55); and group 3--patients who had predonated blood but did not receive a transfusion (15).
The mean final hemoglobin concentrations, the number of patients who lost more than 30 g/L of hemoglobin and the requirements for homologous transfusions.
The rate of homologous transfusion was 1% whether the patients had predonated blood or not. If a more restricted pattern of transfusion been used this rate would have been lower. The final hemoglobin concentration was similar in all three groups. More patients in group 3 (60%) lost more than 30 g/L of hemoglobin compared with the initial hemoglobin value than either group 1 (23%) or group 2 (20%) (p < 0.01).
The routine inclusion in autologous blood programs of patients scheduled to undergo breast reduction surgery is not warranted.
评估接受乳房缩小手术患者的围手术期失血量和输血需求,并衡量自体血计划对异体输血需求的影响。
对1988年至1992年间接受乳房缩小手术的患者进行图表回顾。
渥太华综合医院,一家设有外科培训项目但没有整形手术项目的教学医院。
纳入回顾的是研究期间接受乳房缩小手术的所有153例患者。20例患者被排除,原因是无法获得术前采血或最终血红蛋白浓度。其余133例患者分为三组:第1组——未术前采血的患者(63例);第2组——术前采血并接受输血的患者(55例);第3组——术前采血但未接受输血的患者(15例)。
平均最终血红蛋白浓度、血红蛋白下降超过30 g/L的患者数量以及异体输血需求。
无论患者是否术前采血,异体输血率均为1%。如果采用更严格的输血模式,该比率会更低。三组患者的最终血红蛋白浓度相似。与第1组(23%)或第2组(20%)相比,第3组中更多患者(60%)的血红蛋白较初始值下降超过30 g/L(p<0.01)。
计划接受乳房缩小手术的患者常规纳入自体血计划并无必要。
