BACKGROUND:Most low-risk obstetric patients do not have crossmatched blood available to treat unexpected postpartum hemorrhage. An emergency-release blood transfusion (ERBT) program is critical for hospitals with obstetrical services. We performed a retrospective analysis of obstetrical ERBTs administered in our multihospital system. DESIGN AND METHODS:We collected data from the past 8 years at all Intermountain Healthcare hospitals on every ERBT after postpartum hemorrhage; logging circumstances, number and type of transfused products, and outcomes. RESULTS:Eighty-nine women received ERBT following 224,035 live births, for an incidence of 3.97 transfused women/10,000 births. The most common causally-associated conditions were: uterine atony (40%), placental abruption/placenta previa (16%), retained placenta (11%), and uterine rupture (5%). The mean number of total units transfused was 7.9 (range 1-76). The mean number of red blood cells (RBCs) transfused was 4.8, the median 4, and SD was ±4.4. Massive transfusion protocols (MTPs) for trauma recommend using a ratio of 1:1:1 or 2:1:1 of RBC:FFP:Platelets, however the ratios varied widely for postpartum hemorrhage. Only 1.5% received a 1:1:1 ratio and 7.5% received a 2:1:1 ratio. Nineteen percent (17/89) of women underwent hysterectomy, 7% (6/89) had uterine artery embolization, 36% (32/89) had an intensive care unit admission, and 1% (1/89) died. CONCLUSION:Emergency transfusion for postpartum hemorrhage occurred after 1/2500 births. Most women received less FFP and platelets than recommended for traumatic hemorrhage. A potentially better practice for postpartum hemorrhage would be a balanced ratio of blood products, transfusion of low-titer, group O, cold-stored, whole blood, or inclusion in a MTP.


背景: 大多数低危产科患者没有交叉配血可用于治疗意外产后出血。紧急释放输血 (ERBT) 项目对于有产科服务的医院至关重要。我们对我们多医院系统中给予的产科 ERBTs 进行了回顾性分析。 设计和方法: 我们在所有山间医疗保健医院收集了过去 8 年产后出血后每次 ERBT 的数据; 记录情况、输血产品的数量和类型以及结局。 结果: 89 例妇女在 224,035 例活产后接受了 ERBT,发生率为 3.97 例输血妇女/10,000 例分娩。最常见的因果关系是: 子宫收缩乏力 (40%) 、胎盘早剥/前置胎盘 (16%) 、胎盘滞留 (11%) 和子宫破裂 (5%)。平均总输注单位数为 7.9 (范围 1-76)。平均输注红细胞 (rbc) 数为 4.8,中位数为 4,SD 为 ± 4.4。创伤的大量输血方案 (MTPs) 推荐使用 RBC:FFP: 血小板的 1:1:1 或 2:1:1 的比例,然而产后出血的比例差异很大。只有 1.5% 的人获得 1:1:1 的比例,7.5% 的人获得 2:1:1 的比例。17/89 (7%) 的妇女接受了子宫切除术,6/89 (36%) 接受了子宫动脉栓塞术,32/89 (1%) 接受了重症监护病房,1/89 () 死亡。 结论: 产后出血急诊输血发生在 1/2500 例分娩后。大多数妇女接受的 FFP 和血小板比外伤性出血推荐的少。产后出血的一个潜在的更好的做法是血液制品的平衡比例、低滴度输血、 O 组、冷储存、全血或包含在 MTP 中。

METHODS::Maternal lifestyle affects both mother health and pregnancy outcome in humans. Several studies have demonstrated that interventions oriented towards reducing stress and anxiety have positive effects on pregnancy complications such as preeclampsia, excessive gestational weight, gestational diabetes and preterm birth. In this work, we showed that the environmental enrichment (EE), defined as a noninvasive and biological significant stimulus of the sensory pathway combined with voluntary physical activity, prevented preterm birth (PTB) rate in a 41% in an inflammatory mouse model induced by the systemic administration of bacterial lipopolysaccharide (LPS). Furthermore, we found that EE modulates maternal metabolism and produces an anti-inflammatory environment that contributes to pregnancy maintenance. In pregnant mice uterus, EE reduces the expression of TLR4 and CD14 (the LPS receptor and its coactivator protein), preventing the LPS-induced increase in PGE2 and PGF2α release and nitric oxide synthase (NOS) activity. In cervical tissue, EE inhibits cervical ripening events, such as PGE2 release, matrix metalloproteinase (MMP)-9 increased activity and neutrophil recruitment, therefore conserving cervical function. It seems that EE exposure could mimic the stress and anxiety-reducing techniques mentioned above, explaining, at least partially, the beneficial effects of having a healthy lifestyle before and during gestation. Furthermore, we propose that designing an EE protocol for humans could be a noninvasive and preventive therapy for pregnancy complications, averting pre-term birth occurrence and dreaded sequelae that are present in the offspring born to soon.

METHODS:PROBLEM:We aimed to investigate the main causes of recurrent miscarriage (RM) in patients with losses after spontaneous gestation (SG) and after in vitro fertilization (IVF). METHOD OF STUDY:A prospective case-control study was conducted. The eligible patients were women who had experienced two or more consecutive abortions after less than 12 weeks gestation, two consecutive losses after SG or two consecutive losses after IVF. All patients were subjected to the following evaluations: karyotyping of the aborted material, alloimmune and autoimmune marker testing, and acquired and hereditary thrombophilia marker testing. RESULTS:In total, 58 patients were eligible: 32 patients with RM after SG and 26 patients with RM after IVF. The factors associated with RM were genetic (29%), immune (14%), thrombophilic (21%), and thrombophilic and immune (24%), and only 12% of the cases were idiopathic. Comparing the two study groups (SG and IVF), all studied factors were similar, except for a higher ANA positivity observed in the SG group (SG 30.4% versus IVF 5.3%, OR 8.6 (CI 1.1 - 21.1, P 0.048). CONCLUSIONS:Our study identified the possibly factors associated with recurrent miscarriage in 86% of the cases, and these factors appear to be similar in patients with recurrent miscarriage after spontaneous gestation and IVF. This study demonstrates that IVF with PGT-A with euploid embryo transfer could reduce abortions by up to 29%, but other factors needs to be investigated even in patients undergoing in vitro fertilization.

METHODS:OBJECTIVES:To evaluate the impact of pre-operative Music Therapy (MT) on pain in first-trimester abortion under local anaesthesia (ALA). DESIGN:Randomised controlled trial comparing patients undergoing a first-trimester ALA with or without a pre-operative MT session. SETTING:University hospital of Angers from November 2016 to August 2017. POPULATION:Patients who underwent first-trimester abortion under ALA. METHODS:Patients allocated to MT group underwent a pre-operative 20 minutes session of MT. MAIN OUTCOME MEASURES:Pain was assessed using a visual analogue scale (VAS) just before the procedure, during the procedure, at the end of the procedure and upon returning to the ward. RESULTS:159 patients were randomised (80 in MT group, and 79 in the control group). 2 patients were excluded from the control group and 6 from the MT group. Therefore, 77 patients were analysed in the control group and 74 in the MT group. The intensity of pain were similar in both the MT group and the Control group just before the procedure (VAS: 4.0±2.9 vs. 3.6±2.5, p=0.78), during the procedure (VAS: 5.3±2.5 vs. 4.9±2.9, p=0.78), at the end of the procedure (VAS: 2.7±2.4 vs. 2.6±2.4, p=0.43) and upon returning to the ward (VAS:1.8±2.0 vs. 1.5±2.0, p=0.84). The difference in pain between entering the department and returning to the room after the procedure was similar between the MT and Control groups (0.3±2.5 vs. 0.3±2.4 VAS levels difference; p=0.92). CONCLUSION:Music therapy session before an ALA procedure resulted in no improvement in patient perception of pain during a first-trimester abortion.
