    背景:由于硬膜外血肿的风险,因子VII缺乏被认为是神经轴麻醉的禁忌症。
    方法:一名32岁的G1P0产妇,患有严重的VII因子缺乏症,在妊娠32周时接受麻醉咨询。初始凝血研究对于升高的INR(2.0)和6%的低因子VII水平具有重要意义。经过跨学科的讨论,如果在给予重组激活因子VII(rFVIIa)后对她的凝血研究进行校正,则确定可以提供神经轴镇痛.患者在妊娠36周时接受rFVIIa攻击。她接受22mcg/kg的rFVIIa,并且在20分钟后分析凝血研究,其显示凝血病的完全纠正。患者在39周零3天到医院分娩,接受2毫克rFVIIa和20分钟后,成功接受硬膜外导管.在分娩过程中每3小时监测她的INR,如果INR为1.3或更高,则给予rFVIIa。她在22小时内需要三次额外的剂量。无出血或血栓事件发生,患者出院后没有出现并发症。
    结论:该病例强调了严重VII因子缺乏的产妇硬膜外导管的安全管理。
    BACKGROUND: Factor VII deficiency is considered a contraindication to neuraxial anesthesia due to the risk of an epidural hematoma.
    METHODS: A 32 year old G1P0 parturient with severe factor VII deficiency presented for an anesthesiology consultation at 32 weeks gestation. Initial coagulation studies were significant for an elevated INR (2.0) and a low factor VII level of 6%. After interdisciplinary discussion, it was decided that neuraxial analgesia could be offered if her coagulation studies corrected after administration of recombinant activated factor VII (rFVIIa). The patient presented at 36 weeks gestation for a rFVIIa challenge. She received 22 mcg/kg rFVIIa and coagulation studies were analyzed 20 minutes later which showed complete correction of the coagulopathy. The patient presented to the hospital at 39 weeks and 3 days for delivery, received 2 mg rFVIIa and 20 minutes later, successfully received an epidural catheter. Her INR was monitored every 3 hours during her labor course and rFVIIa was given if the INR was 1.3 or greater. She required three additional doses over 22 hours. No bleeding or thrombotic events occurred, and the patient was discharged home without complications.
    CONCLUSIONS: This case highlights the safe management of an epidural catheter in a parturient with severe factor VII deficiency.

    下腔静脉发育不全(AIVC)是一种极为罕见的先天性异常。在AIVC,来自下肢的静脉血流主要通过奇系统和半奇系统进入上腔静脉,形成吻合侧支血管。妊娠子宫腹内压的整体增加可能进一步压迫侧支系统,增加静脉淤滞,减少静脉回流。我们介绍了一名37岁的AIVC孕妇的治疗方法,该孕妇接受了去甲肾上腺素输注和全身麻醉的剖腹产。她坐下时呼吸急促,走路或坐直时头晕发作,随后出现心动过速。使用动脉脉搏轮廓CO监测器监测心脏状态。我们没有观察到CO的大幅波动,SV,诱导和插管期间以及分娩期间的MAP。我们认为,通过剖腹产从诱导到麻醉的去甲肾上腺素输注有助于这一结果。交感神经激活引起静脉收缩,显著增加静脉回流,维持血流动力学稳定。
    Agenesis of inferior vena cava (AIVC) is an extremely rare congenital abnormality. In AIVC, venous flow from the lower extremities enter superior vena cava mainly through the azygous and hemiazygous system, forming anastomotic collateral vessels. A global increase in intra-abdominal pressure by the gravid uterus may further stress the collateral system, increase venous stasis and decrease venous return. We present the management of a 37-year old pregnant woman with AIVC who underwent caesarean section with norepinephrine infusion and general anaesthesia. She presented with shortness of breath when seated, episodes of dizziness while walking or sitting upright with subsequent tachycardia. Cardiac status was monitored using an arterial pulse contour CO monitor. We did not observe large fluctuations in CO, SV, MAP during induction and intubation as well as during delivery. We believe that administration of an infusion of norepinephrine from induction to anaesthesia through caesarean section contributed to this result. Sympathetic activation caused venoconstriction, which significantly increased venous return and maintained haemodynamic stability.

    背景:巴氯芬,中枢神经系统中的γ-氨基丁酸受体B型激动剂,是中枢神经系统调节剂中用于治疗神经源性肌肉痉挛的一线药物。虽然巴氯芬最常用于肠内给药,严重痉挛的患者可能是鞘内泵给药巴氯芬的候选人。目前,只有9项研究报告了在妊娠和分娩期间鞘内注射巴氯芬(ITB).
    方法:我们描述了一名女性患者,有儿童期双侧下肢特发性痉挛史,由ITB泵控制,她在生命的第三个十年晚期怀孕,分娩了一个健康的婴儿。患者在怀孕期间需要多次增加巴氯芬疗程。
    结论:我们的案例,除了现有的关于怀孕期间ITB的文献,提示妊娠中的ITB治疗具有较低的致畸性和婴儿戒断性癫痫发作风险;然而,较大,对照研究是必要的,以使这些结论有信心。照顾怀孕ITB患者的医疗保健提供者应认识到此类患者在怀孕期间需要增加ITB剂量以实现充分的症状控制的可能性。
    BACKGROUND: Baclofen, a gamma-aminobutyric acid receptor type B agonist in the central nervous system, is the first-line medication among central nervous system modulating agents for the treatment of neurogenic muscle spasticity. While baclofen is most often administered enterally, patients with severe spasticity may be candidates for baclofen delivered by intrathecal pump. Currently, there are only nine studies reporting on the use of intrathecal baclofen (ITB) during pregnancy and childbirth.
    METHODS: We described a female patient with a history of childhood idiopathic spasticity of the bilateral lower extremities that was controlled by ITB pump who became pregnant in her late third decade of life and delivered a healthy infant. The patient required multiple increases of her baclofen course over the course of her pregnancy.
    CONCLUSIONS: Our case, alongside the existing literature on ITB during pregnancy, suggests that ITB therapy in pregnancy poses a low risk of teratogenicity and infant withdrawal seizures; however, larger, controlled studies are necessary to make those conclusions with confidence. Healthcare providers caring for pregnant ITB patients should be cognizant of the potential for such patients to require increased doses of ITB during pregnancy to achieve adequate symptom control.

    背景:孟加拉国在过去几十年中经历了孕产妇和新生儿死亡率令人印象深刻的下降,自2000年以来的年下降率超过4%。我们全面评估了推动孟加拉国成功降低死亡率的卫生系统和非健康因素。
    方法:我们实施了一个全面的概念框架,并分析了现有的家庭调查,以了解死亡率的趋势和不平等,干预覆盖率和护理质量。其中包括在调查之前的15年中进行的12次家庭调查,总数超过130万。自1990年以来,文献和案头审查允许重建政策和方案的制定和筹资。这些补充了关键的线人访谈,以了解实施决策和战略。
    结果:孟加拉国优先考虑早期人口政策,以通过1970年代中期发起的基于社区的计划生育方案来管理其快速增长的人口。在1990年代和2000年代,重点是增加获得卫生设施的机会,导致设施交付量迅速增加,干预覆盖面和获得紧急产科护理,私人设施的巨大贡献。一个分散的卫生系统组织,从社区到中央,对私营营利性部门增长的开放,对孕产妇和新生儿健康的有效融资分配使进展迅速。其他关键杠杆包括减贫,妇女赋权,农村发展,以及数据生成和使用的文化。然而,最近的经验数据表明,死亡率下降的速度正在放缓。
    结论:孟加拉国证明了有效的多部门方法和持续的计划,在降低孕产妇和新生儿死亡率方面取得快速进展。近期死亡率趋势的放缓表明,该国将需要修订其战略,以实现可持续发展目标。随着生育率达到更替水平,孕产妇和新生儿死亡率的进一步增长将需要优先考虑普遍获得高质量的设施交付,解决不平等问题,包括农村贫困人口。
    BACKGROUND: Bangladesh experienced impressive reductions in maternal and neonatal mortality over the past several decades with annual rates of decline surpassing 4% since 2000. We comprehensively assessed health system and non-health factors that drove Bangladesh\'s success in mortality reduction.
    METHODS: We operationalised a comprehensive conceptual framework and analysed available household surveys for trends and inequalities in mortality, intervention coverage and quality of care. These include 12 household surveys totalling over 1.3 million births in the 15 years preceding the surveys. Literature and desk reviews permitted a reconstruction of policy and programme development and financing since 1990. These were supplemented with key informant interviews to understand implementation decisions and strategies.
    RESULTS: Bangladesh prioritised early population policies to manage its rapidly growing population through community-based family planning programmes initiated in mid-1970s. These were followed in the 1990s and 2000s by priority to increase access to health facilities leading to rapid increases in facility delivery, intervention coverage and access to emergency obstetric care, with large contribution from private facilities. A decentralised health system organisation, from communities to the central level, openness to private for-profit sector growth, and efficient financing allocation to maternal and newborn health enabled rapid progress. Other critical levers included poverty reduction, women empowerment, rural development, and culture of data generation and use. However, recent empirical data suggest a slowing down of mortality reductions.
    CONCLUSIONS: Bangladesh demonstrated effective multi-sectoral approach and persistent programming, testing and implementation to achieve rapid gains in maternal and neonatal mortality reduction. The slowing down of recent mortality trends suggests that the country will need to revise its strategies to achieve the Sustainable Development Goals. As fertility reached replacement level, further gains in maternal and neonatal mortality will require prioritising universal access to quality facility delivery, and addressing inequalities, including reaching the rural poor.

    孕妇可能会增加SARS-COV-2感染的风险。尽管关于COVID-19疗效和安全性的证据正在增加,但对妊娠不良事件的认识仍有改进的空间,比如流产。我们使用真实世界探索了COVID-19疫苗与流产风险的关系。我们使用BIFAP数据库确定了一组接种疫苗的妊娠,该数据库包含西班牙护理患者的系统记录数据(N=4054)。然后,我们使用经过验证的算法将其限制为那些流产的女性(N=607)。其中,我们进行了病例交叉设计,以评估间歇性暴露对流产风险的影响.使用两种分析方法计算调整后的赔率及其置信区间:条件逻辑回归和广义线性混合效应模型。共有225人(37.1%)年龄在35-39岁之间。最常见的合并症是哮喘,偏头痛,胃炎,和甲状腺功能减退。总共14.7%的人只接受了一剂COVID-19,85.3%的人接受了两剂,分别。在流产前7天接种疫苗的妇女中,有36.8%的妇女一剂和27.6%的两剂。使用条件逻辑回归对流产风险的相应调整估计如下:1.65(95%CI0.85-3.23)当使用一次剂量的女性中3个控制时刻的总和时,使用两种剂量的女性为1.02(95%CI0.72-1.46),使用整个研究人群为1.03(95%CI0.72,1.46)。进行广义线性混合效应模型时获得了非常相似的结果。尽管根据剂量数量发现了矛盾的结果,但与COVID-19疫苗相关的流产发作风险没有总体增加。需要更大样本量的进一步研究来评估这种关联。
    Pregnant women might have an increased risk of SARS-COV-2 infection. Although evidence towards the efficacy and safety of COVID-19 is growing still there is room for improvement on the knowledge towards pregnancy adverse events, such as miscarriage. We explored the association of COVID-19 vaccine with the risk of miscarriages using the Real-World. We identified a cohort of vaccinated pregnancies using the BIFAP database which contains systematically recorded data on care patients in Spain (N = 4054). We then restricted it to those women who had a miscarriage using a validated algorithm (N = 607). Among them, we performed a case-crossover design to evaluate the effect of intermittent exposures on the risk of miscarriage. Adjusted Odds Ratio with their confidence intervals were calculated using two analytical approaches: conditional logistic regression and Generalized Linear Mixed-Effects Models. A total of 225 (37.1%) were aged 35-39 years. The most common comorbidities were asthma, migraine, gastritis, and hypothyroidism. A total of 14.7% received only one dose of COVID-19 and 85.3% two doses, respectively. A total of 36.8% of women with one dose and 27.6% with two doses received the vaccine 7 days prior to the miscarriage. Corresponding adjusted estimates for the risk of miscarriage using the conditional logistic regression where as follows: 1.65 (95% CI 0.85-3.23) when using as the sum of 3 control moments among women with one dose, 1.02 (95% CI 0.72-1.46) among women with two doses and 1.03 (95% CI 0.72, 1.46) using the whole study population. Very similar results were obtained when conducting the Generalized Linear Mixed-Effects Models. There was no overall increased risk of miscarriage onset associated with COVID-19 vaccine although contradictory results were found according to the number of doses. Further studies are required with larger sample sizes to assess this association.

    目的:对作者的贡献,包括病例报告,应该适当评估。我注意到很少有临床医生被列为合著者的病例报告,促使这项调查。我试图就这种趋势的可能原因提出建议。
    方法:我查看了发表在《妇产科研究杂志》上的病例报告,医学病例报告杂志,和BMJ病例报告。我确定了将临床医生列为合著者的病例报告。我咨询了Jichi医科大学的八名教授,以确定他们部门的病例报告是否包括临床医生作为共同作者,如果不是,原因。
    结果:在日本机构发表在《妇产科研究杂志》上的65例病例报告中,只有一篇论文将临床医生列为合著者。在医学病例报告和BMJ病例报告杂志上发表的100和50篇论文中,分别,没有人将诊所医生列为合著者。八分之六的教授承认从未考虑过将临床医生作为合著者的想法。
    结论:以临床医生为共同作者的病例报告的稀缺性超出了日本妇产科,涵盖世界各地的各种专业。中心医生不认为临床医生应该是合著者。转移患者的临床医生应被视为候选合著者,具体取决于他/她的科学贡献。这种方法可以营造一个鼓励医生为学术写作做出贡献的环境,不管他们的工作场所。
    OBJECTIVE: Contribution to the authorship, including that for case reports, should be appropriately evaluated. I have noticed a scarcity of case reports with clinic doctors listed as coauthors, prompting this investigation. I sought to offer suggestions on the possible reasons for this trend.
    METHODS: I checked case reports published in the Journal of Obstetrics and Gynaecology Research, the Journal of Medical Case Reports, and the BMJ Case Reports. I identified case reports listing a clinic doctor as a coauthor. I consulted eight professors at Jichi Medical University to ascertain whether case reports from their departments included clinic doctors as coauthors and, if not, the reasons.
    RESULTS: Among 65 case reports from Japanese institutes published in the Journal of Obstetrics and Gynaecology Research, only one paper lists a clinic doctor as a coauthor. Of 100 and 50 papers published in the Journal of Medical Case Reports and BMJ Case Reports, respectively, none listed a clinic doctor as a coauthor. Six out of eight professors admitted to never considering the idea of including clinic doctors as coauthors.
    CONCLUSIONS: The scarcity of case reports with clinic doctors as coauthors extends beyond Japanese obstetrics and gynecology, encompassing various specialties worldwide. Center doctors do not think of the idea that a clinic doctor should be a coauthor. A clinic doctor who transferred the patient should be considered as a candidate coauthor depending on his/her scientific contribution. Such an approach could foster an environment encouraging doctors to contribute to academic writing, regardless of their workplace.

    背景:文献中已经描述了脊髓硬膜外血肿(SEH)的风险,但在同一研究中尚未评估对各种患者人群的影响。我们确定了SEH的危险因素,并计算了儿科康复的OR,根据手术前的神经功能缺损程度,成人和产科(OB)患者。
    方法:对成人非OB病例进行分类,无论他们是否使用抗凝剂;SEH与神经轴或疼痛程序有关;或者是否遵守美国区域麻醉学会(ASRA)指南。从1954年到2022年7月,通过PubMed和Embase在英语文献中的搜索确定了符合条件的病例。
    结果:共评估940例。在儿科病例中,SEH通常是自发的,与凝血病或运动创伤有关。OB病例为自发性或与神经轴注射有关。在抗凝剂的成年人中,SEH大多是自发的,没有相关的病因或与神经轴手术有关。尽管遵守ASRA指南,但仍发生SEH。在未服用抗凝剂的非OB成年人中,SEH是因为外伤,神经轴注射,手术或其他原因。神经功能恢复与手术前神经功能缺损程度有关。
    结论:我们的数据显示在所有患者人群中自发性SEH占优势。尽管遵循了ASRA指南,尤其是使用多种抗凝剂的患者。手术前受损较少的患者完全恢复的可能性更高,无论手术和症状发作之间的间隔。
    BACKGROUND: The risk of spinal epidural hematoma (SEH) has been described in the literature but the impact in various patient populations has not been assessed in the same study. We identified the risk factors for SEH and calculated the OR for recovery in the pediatric, adult and obstetric (OB) patients based on the degree of neurological deficit before surgery.
    METHODS: Adult non-OB cases were categorized whether they were on anticoagulants or not; SEH was related to neuraxial or pain procedure; or whether there was adherence to the American Society of Regional Anesthesia (ASRA) guidelines. Eligible cases were identified through PubMed and Embase searches in the English literature from 1954 to July 2022.
    RESULTS: A total of 940 cases were evaluated. In the pediatric cases, SEH was typically spontaneous, related to coagulopathy or athletic trauma. OB cases were spontaneous or related to neuraxial injections. Among adults on anticoagulant(s), SEH was mostly spontaneous with no related etiology or related to neuraxial procedure. SEH occurred despite adherence to the ASRA guidelines. Among non-OB adults not on anticoagulants, SEH was due to trauma, neuraxial injections, surgery or other causes. Neurological recovery was related to the degree of neurological deficit before surgery.
    CONCLUSIONS: Our data show a preponderance of spontaneous SEH in all patient populations. SEH developed even though the ASRA guidelines were followed, especially in patients on multiple anticoagulants. Patients with less impairment prior to surgery had a higher likelihood of complete recovery, regardless of the interval between surgery and onset of symptoms.

    背景:在英国,每年有1600个婴儿死亡,在妊娠20-28周出生期间或出生后立即。这种丧亲对父母的身心健康和晚期死产(>28周妊娠)有类似的影响。对晚期死产(包括仰卧位)的潜在可改变的危险因素的理解已经影响了国际临床实践。现在迫切需要信息,以类似地告知临床实践并帮助准妈妈/父母做出决策。解决20至28周之间妊娠损失的不平等问题。
    方法:本研究的重点是妊娠20-28周流产风险的哪一部分与适合公共卫生运动/产前护理适应的暴露有关。非异常单胎婴儿丢失的病例对照研究(通过流产,死产或新生儿早期死亡)200至276(n=316)和随机选择的对照组妊娠(2:1比例;n=632)。通过参与者回忆(研究人员管理的问卷)和从同期医疗记录中提取来收集数据。将计算未调整/混杂调整的OR。假设暴露患病率为30%-60%,则可以检测到与OR≥1.5的早期死产相关的暴露(p<0.05,β>0.80)。
    背景:已获得伦敦季节性研究伦理委员会的NHS研究伦理批准(23/LO/0622)。结果将在国际会议上发表,并在同行评审的开放获取期刊上发表。这项研究的信息将使医疗保健专业人员和孕妇的产前保健和教育得以发展,以降低早期死产的风险。
    背景:NCT06005272。
    In the UK, 1600 babies die every year before, during or immediately after birth at 20-28 weeks\' gestation. This bereavement has a similar impact on parental physical and psychological well-being to late stillbirth (>28 weeks\' gestation). Improved understanding of potentially modifiable risk factors for late stillbirth (including supine going-to-sleep position) has influenced international clinical practice. Information is now urgently required to similarly inform clinical practice and aid decision-making by expectant mothers/parents, addressing inequalities in pregnancy loss between 20 and 28 weeks.
    This study focuses on what portion of risk of pregnancy loss 20-28 weeks\' gestation is associated with exposures amenable to public health campaigns/antenatal care adaptation. A case-control study of non-anomalous singleton baby loss (via miscarriage, stillbirth or early neonatal death) 20+0 to 27+6 (n=316) and randomly selected control pregnancies (2:1 ratio; n=632) at group-matched gestations will be conducted. Data is collected via participant recall (researcher-administered questionnaire) and extraction from contemporaneous medical records. Unadjusted/confounder-adjusted ORs will be calculated. Exposures associated with early stillbirth at OR≥1.5 will be detectable (p<0.05, β>0.80) assuming exposure prevalence of 30%-60%.
    NHS research ethical approval has been obtained from the London-Seasonal research ethics committee (23/LO/0622). The results will be presented at international conferences and published in peer-reviewed open-access journals. Information from this study will enable development of antenatal care and education for healthcare professionals and pregnant people to reduce risk of early stillbirth.
