剖宫产术中回收式自体输血在中央型前置胎盘患者的应用

Application of Salvaged Autotransfusion During Cesarean Section in Patients with Central Placenta Previa

目的在中央型前置胎盘患者剖宫产术中采用回收式自体输血技术,探讨该方法在产科应用的安全性和有效性。方法选择我院2016年8月至11月期间中央型前置胎盘行择期剖宫产患者,观察和比较患者手术前后及术后24h血常规、凝血常规、血液回收及回输血量、异体血输注量及围术期并发症等情况。结果 48例中央型前置胎盘患者纳入本研究,其中40例(83.3%)的中央型前置胎盘患者采用术中回收式自血回输。平均自体血回收量(1047.0±472.2)mL,自体血回输量(681.9±263.4)mL。95%的患者不需要输注异体红细胞悬液。所有患者手术均顺利完成,无围术期羊水栓塞、低血压、发热及溶血等不良反应发生的证据。结论剖宫产术中回收式自体血回输可安全有效的应用于产科前置胎盘患者。

Objective To evaluate the efficacy and safety of salvaged autotransfusion in application of obstetrics by using this technique during cesarean section in patients with central placenta previa. Methods Patients with central placenta previa undergoing elective cesarean sectionfrom August to November 2016 in our hospital were selected. The blood routine, coagulation routine, blood recovery and autotransfusionvolume, volume of transfusion of allogeneic blood and perioperative complications were observed and compared before and after the operation and 24 hoursafter the surgery. Results 48 patients with central placenta previa were included in this study, of which 40 （83.3 % ）cases of the patients with central placenta previa underwent intraoperative autotransfusion. The average volume of autologous blood recovery was（ 1047. 0 ±472. 2）mL,and the volume of autologous blood transfusion was （681.9 ± 263.4） mL. 95 % of patients did not require infusion of allogeneic red cell suspensions. All patients were successfully performed without evidence of perioperative amniotic fluid embolism, hypotension, fever, hemolysis, and other adverse events. Conclusion Salvaged autotransfusion during cesarean section is safe and effective for patients with placenta previa in obstetrical department.
