Our objective was to determine the incidence of blood administration after cesarean delivery and whether such transfusions are always beneficial. In this retrospective study 1610 women underwent cesarean delivery during a 2-year period and 127 of these patients had hemorrhage during or after operation. Of these subjects 103 received blood because of intraoperative hemorrhage, a reduction in the hematocrit of more than 10 points, or because the postoperative hematocrit was < 24%. These subjects were compared with the remaining women (n = 24) who met the same criteria for hemorrhage but did not receive transfusion. The maternal age, race, and parity were similar in both groups. The estimated blood loss (873 +/- 484 ml) and the preoperative hematocrit (33.4% +/- 6.4%) in the women who did not receive transfusion were not significantly different from those of patients who received packed red blood cells (854 +/- 576 ml and 30.0% +/- 5.4%, respectively). The postdelivery hematocrit was similar in both groups: 25.9% +/- 4.3% in the nontransfused group and 24.5% +/- 5.6% in the transfused group. Patients in the transfused group received a mean of 3.8 +/- 4.9 units of packed red blood cells, with a range of 1 to 40 units. The mean equilibrated (stable) hematocrit after transfusion was 28.4% +/- 5.4%, which was significantly greater than the mean equilibrated postoperative hematocrit of 22.7% +/- 4.6% in patients who did not receive transfusion (p < 0.0001). Nonetheless, the hospital stay, incidence of postoperative infection, and incidence of wound complications were similar in the two groups.(ABSTRACT TRUNCATED AT 250 WORDS)
我们的目的是确定剖宫产术后输血的发生率，以及这种输血是否总是有益的。在这项回顾性研究中，1610名女性在两年期间接受了剖宫产，其中127名患者在手术期间或术后出现出血。在这些受试者中，103人因术中出血、血细胞比容降低超过10个百分点或术后血细胞比容<24%而接受输血。将这些受试者与其余24名符合相同出血标准但未接受输血的女性进行比较。两组的产妇年龄、种族和产次相似。未接受输血的女性估计失血量（873±484ml）和术前血细胞比容（33.4%±6.4%）与接受浓缩红细胞输血的患者（分别为854±576ml和30.0%±5.4%）无显著差异。两组产后血细胞比容相似：未输血组为25.9%±4.3%，输血组为24.5%±5.6%。输血组患者平均接受3.8±4.9单位浓缩红细胞，范围为1至40单位。输血后平均平衡（稳定）血细胞比容为28.4%±5.4%，显著高于未接受输血患者术后平均平衡血细胞比容22.7%±4.6%（p<0.0001）。尽管如此，两组的住院时间、术后感染发生率和伤口并发症发生率相似。（摘要截断于250字）
