Cohort study 

研究目的:

明确高危出血风险产妇剖宫产中阴道血的自体血回输的可行性和安全性;拓展IOCS技术的临床应用场景和节省异体血资源的同时,为一些血资源短缺、经济匮乏又或者是因宗教信仰不能输血的地区提供更多的抢救选择从而提高高危妊娠剖宫产产妇的生存率。  

Objectives of Study:

To determine the feasibility and safety of autologous blood transfusion from vaginal blood during cesarean sections in pregnant women with a high risk of hemorrhage; to expand the clinical applications of intraoperative cell salvage (IOCS) technology and conserve allogeneic blood resources. Additionally, to provide more resuscitation options for regions facing blood shortages, economic constraints, or religious restrictions on blood transfusion, thereby improving the survival rate of high-risk pregnant women undergoing cesarean sections.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.产妇年龄在18岁以上,诊断为美国麻醉医师协会(ASA)分级II-III级。 2.计划性剖宫产且预计有高危出血风险和阴道失血量>100ml的产妇(符合以下至少一项:中央型前置胎盘、胎盘植入、既往产后出血史、双胎妊娠)。 3.自愿加入本研究,并签署知情同意书。

Inclusion criteria

1.Pregnant women aged 18 years or older, classified as American Society of Anesthesiologists (ASA) grade II-III. 2.Undergoing planned cesarean section with an expected high risk of hemorrhage and vaginal blood loss >100 mL (meeting at least one of the following criteria: complete placenta previa, placenta accreta, history of postpartum hemorrhage, twin pregnancy). 3.Willing to participate in the study and sign an informed consent form.

排除标准:

1.患者及家属拒绝参与实验 2.技术性禁忌症(如严重溶血) 3.Rh阴性,或伴有血液疾病、自身免疫性疾病、急性脂肪肝/HELLP综合征的患者 4.术前接受抗凝治疗,并在研究前3个月内接受过异体输血,或在妊娠期间参与其他临床研究以及无法进行阴道血回收的产妇。 5.存在可能导致无法配合研究的疾病,如精神疾病、语言理解障碍等。 6.镰刀型红细胞贫血患者

Exclusion criteria:

1.Patients or their families refuse to participate in the study. 2.Technical contraindications (e.g., severe hemolysis). 3.Rh-negative patients or those with blood disorders, autoimmune diseases, acute fatty liver of pregnancy (AFLP), or HELLP syndrome. 4.Patients who received anticoagulation therapy preoperatively, underwent allogeneic blood transfusion within the past three months, participated in other clinical studies during pregnancy, or are unable to undergo vaginal blood salvage. 5.Presence of conditions that may hinder study participation, such as psychiatric disorders or language comprehension difficulties. 6.Patients with sickle cell anemia.
