    背景和目的脊柱麻醉是下段剖宫产(LSCS)患者的基石,提供更快的起效和高块密度等优点。左旋布比卡因,以其高效和长效特性而闻名,起病较慢。评价鞘内注射芬太尼或咪达唑仑作为左布比卡因辅助用药的安全性。这项研究旨在比较选择性剖宫产术中添加0.5%高压左布比卡因的芬太尼或咪达唑仑提供的术后镇痛时间。次要目标包括评估感觉和运动阻滞的发作和持续时间以及恶心和呕吐的发生率。确定更有效的佐剂将有助于优化脊髓麻醉方案,改善术后结果,并提高患者的舒适度和恢复。方法本研究在SRM医学院附属医院和研究中心进行,钦奈,印度,超过六个月(2023年5月1日至2023年10月1日)。在一项前瞻性随机双盲对照试验中,共有90例接受择期LSCS的患者接受了脊髓麻醉。患者被分为三组:A组接受左旋布比卡因和芬太尼,B组接受左布比卡因和咪达唑仑,C组给予左旋布比卡因生理盐水。块特性,术后镇痛,血液动力学稳定性,并对并发症进行了评估。在指定的时间点进行评估:术中,前30分钟每5分钟,接下来的一个小时每10分钟,每两个小时六个小时,术后每4小时到24小时。统计分析使用单向方差分析(ANOVA)。结果与A组和C组(均为145秒)相比,B组(左布比卡因联合咪达唑仑)表现出更短的感觉阻滞开始时间(88秒)(p<0.001)。A组(左旋布比卡因加芬太尼)的最大运动阻滞时间(p=0.045)短于B组和C组。A组(127.5分钟)的感觉阻滞持续时间明显长于B组(60分钟)和C组(69分钟)(p<0.001)。与B组(147分钟)和C组(177分钟)相比,A组(251分钟)的运动阻滞持续时间也延长(p=0.045)。A组的第一次镇痛需求延迟(248分钟),而B组(115分钟)和C组(90分钟)(p<0.001)需要更频繁的镇痛。A组术后恶心呕吐发生率较高。结论咪达唑仑加速感觉阻滞的发作,而芬太尼延长麻醉持续时间,而不显著影响运动阻滞。芬太尼延迟了第一次镇痛需求,而咪达唑仑减少了术后恶心,呕吐,颤抖着。
    Background and objectives Spinal anesthesia stands as a cornerstone for patients undergoing lower segment cesarean section (LSCS), offering advantages like faster onset and high block density. Levobupivacaine, known for its high potency and long-acting nature, has a slower onset. The safety of intrathecal fentanyl or midazolam is evaluated as an adjuvant to levobupivacaine in parturients. This study aims to compare the duration of postoperative analgesia provided by fentanyl or midazolam added to 0.5% hyperbaric levobupivacaine in elective cesarean sections. Secondary objectives include evaluating the onset and duration of sensory and motor blockade and the incidence of nausea and vomiting. Identifying the more effective adjuvant will help optimize spinal anesthesia protocols, improve postoperative outcomes, and enhance patient comfort and recovery. Methods This study was conducted at SRM Medical College Hospital and Research Centre, Chennai, India, over six months (May 1, 2023, to October 1, 2023). A total of 90 patients undergoing elective LSCS received spinal anesthesia in a prospective randomized double-blinded controlled trial. Patients were allocated to three groups: Group A received levobupivacaine with fentanyl, Group B received levobupivacaine with midazolam, and Group C received levobupivacaine with normal saline. Block characteristics, postoperative analgesia, hemodynamic stability, and complications were assessed. Assessments were conducted at specified time points: intraoperatively, every five minutes for the first 30 minutes, every 10 minutes for the next hour, every two hours for six hours, and every four hours up to 24 hours postoperatively. Statistical analysis utilized one-way analysis of variance (ANOVA). Results Group B (levobupivacaine with midazolam) exhibited a shorter time to sensory block onset (88 seconds) compared to Groups A and C (both 145 seconds) (p < 0.001). Group A (levobupivacaine with fentanyl) showed a shorter time to maximum motor block (p = 0.045) than Groups B and C. The sensory block duration was significantly longer in Group A (127.5 minutes) compared to Group B (60 minutes) and Group C (69 minutes) (p < 0.001). Motor block duration was also prolonged in Group A (251 minutes) compared to Group B (147 minutes) and Group C (177 minutes) (p = 0.045). The first analgesic requirement was delayed in Group A (248 minutes), whereas Groups B (115 minutes) and C (90 minutes) (p < 0.001) required more frequent analgesia. Group A experienced a higher incidence of postoperative nausea and vomiting. Conclusion Midazolam accelerated sensory block onset, while fentanyl prolonged anesthesia duration without significantly affecting motor block. Fentanyl delayed the first analgesic requirement, whereas midazolam reduced postoperative nausea, vomiting, and shivering.

    背景:此产前筛查审查将包括生殖筛查证据以及受孕前和受孕后的方法,利用第一至第三三个月的筛查机会。
    方法:对同行评审的重点产前筛查出版物进行评估和总结。
    结果:应提供并讨论基于证据的生殖产前筛查要素,与怀孕计划或怀孕的人,在孕前(生殖伴侣的遗传载体筛查,个人和家庭(包括生殖伴侣)病史审查,以了解增加的遗传和妊娠发病风险);孕早期(超声检查胎儿约会;胎儿非整倍体筛查以及考虑扩大的胎儿发病率标准,如果合适;孕妇先兆子痫筛查;早期胎儿解剖筛查;早期胎儿心脏筛查);妊娠中期标准胎儿解剖筛查(18-22周),包括心脏;孕妇胎盘和脐带病理学筛查;孕妇早产筛查,宫颈长度测量);妊娠中期(胎儿生长监测;持续早产风险监测)。
    结论:产前生殖筛查具有多个要素,是复杂的,是耗时的,并要求对大多数筛查要素使用测试前和测试后咨询。使用孕前和“一到三个月”需要明确的患者理解和接受。知情同意和知识转移是产前生殖筛查方法的主要目标。
    BACKGROUND: This antenatal screening review will include reproductive screening evidence and approaches for pre-conception and post-conception, using first to third trimester screening opportunities.
    METHODS: Focused antenatal screening peer-reviewed publications were evaluated and summarized.
    RESULTS: Evidenced-based reproductive antenatal screening elements should be offered and discussed, with the pregnancy planning or pregnant person, during Preconception (genetic carrier screening for reproductive partners, personal and family (including reproductive partner) history review for increased genetic and pregnancy morbidity risks); First Trimester (fetal dating with ultrasound; fetal aneuploidy screening plus consideration for expanded fetal morbidity criteria, if appropriate; pregnant person preeclampsia screening; early fetal anatomy screening; early fetal cardiac screening); Second Trimester for standard fetal anatomy screening (18-22 weeks) including cardiac; pregnant person placental and cord pathology screening; pregnant person preterm birth screening with cervical length measurement); Third Trimester (fetal growth surveillance; continued preterm birth risk surveillance).
    CONCLUSIONS: Antenatal reproductive screening has multiple elements, is complex, is time-consuming, and requires the use of pre- and post-testing counselling for most screening elements. The use of preconception and trimesters \'one to three\' requires clear patient understanding and buy-in. Informed consent and knowledge transfer is a main goal for antenatal reproductive screening approaches.

    结论:产科瘘的治疗结果可分为短期和长期结果。尽管这篇综述发现了足够的分析研究,大多数研究设计都很糟糕。建议将来进行更强有力的研究,以指导政策和决策。我们建议研究人员对短期和长期结果独立进行系统评价和荟萃分析。
    BACKGROUND: Obstetrical fistula is an abnormal opening between the reproductive tract and lower urinary and/or gastrointestinal tract resulting from obstetrical complications, affecting nearly two million women worldwide. It imposes physical, economic, social, and mental consequences on the affected women. Treatment outcomes vary and, mostly, surgical treatment results in improved quality of life and successful subsequent pregnancy for survivors.
    OBJECTIVE: The review aimed to chart and examine the treatment outcomes of obstetrical fistula surgical repair in low- and middle-income countries.
    METHODS: This is a scoping review study to identify treatment outcomes of obstetrical fistula surgical repair in low- and middle-income countries. The search was conducted from databases (PUBMED, Embase, CINAHL, Scopus, and Web of Science), and gray literature (Google Scholar, Google, and conference proceedings).
    METHODS: The eligibility criteria were constructed using a participant, concept, and context framework and included study types of primary research, reviews, and reports. Studies without full text and in languages other than English were excluded.
    METHODS: The relevant characteristics of the included studies were extracted on an Excel spreadsheet and analyzed to chart treatment outcomes.
    RESULTS: The review examined the full text of 57 studies on the treatment outcomes of obstetrical fistula. The findings were grouped into two themes: early and late outcomes. The early outcomes included incontinence, surgical-site infection, urine retention, hemorrhage, and retained catheter. The late outcomes included fistula recurrence, residual incontinence, quality of life, reproductive issues, mental health, family and social support, and financial status.
    CONCLUSIONS: The treatment outcomes of obstetrical fistula can be grouped into short-term and long-term outcomes. Although this review found adequate studies for the analysis, most study designs were poor. Stronger studies are recommended in the future to guide policy and decision-making. We would like to suggest that researchers conduct systematic reviews and meta-analyses independently for short-term and long-term outcomes.

    背景:公众和患者的参与可以通过增强研究的相关性和适当性,为优化研究提供重要的见解。世界卫生组织(WHO)参与了一个包容性进程,以确保技术专家和妇女在确定研究差距方面都有发言权,并需要在需要干预但无法使用或未充分利用的环境中增加或重新使用辅助阴道分娩(AVB)。
    方法:我们描述了由世卫组织领导的在线研讨会的方法和成果,以获得妇女代表对AVB研究差距和需求的看法。
    结果:在技术专家根据各种证据综合创建了研究问题列表之后,世卫组织与来自27个主要是低收入和中等收入(LMIC)国家的31名妇女代表组织了四次在线研讨会。妇女对技术专家提出的研究问题的重要性和优先性进行了评分,改进和扩大其中的一些,增加了新的问题,并表达了他们对AVB的主要关切和看法。妇女帮助将研究问题纳入其社区的背景,强调了影响实践和影响妇女在分娩和分娩期间的经验的被忽视因素/维度,强调了AVB的不太突出的后果,并强调了妇女对AVB研究的主要关切。技术专家和妇女代表的综合愿景导致世卫组织出版了一份技术简报。技术简报预计将促进全球研究和行动,与妇女的优先事项密切相关。
    结论:我们描述了吸引女性的成功经验,主要来自LMICs,在确定研究差距和需要重新引入AVB使用方面。这一过程有助于更好地将研究问题与女性的观点结合起来,关注,和优先事项。鉴于很少有关于让低收入国家的女性参与优化研究的报道,这种成功的经验可以作为未来工作的灵感。
    女性代表参与了本手稿中详细描述的研讨会的每个阶段。
    BACKGROUND: Public and patient involvement can provide crucial insights to optimise research by enhancing relevance and appropriateness of studies. The World Health Organization (WHO) engaged in an inclusive process to ensure that both technical experts and women had a voice in defining the research gaps and needs to increase or reintroduce the use of assisted vaginal birth (AVB) in settings where this intervention is needed but unavailable or underused.
    METHODS: We describe the methods and outcomes of online workshops led by WHO to obtain women representatives\' perspectives about AVB research gaps and needs.
    RESULTS: After technical experts created a list of research questions based on various evidence syntheses, WHO organised four online workshops with 31 women\'s representatives from 27 mostly low- and middle-income (LMIC) countries. Women rated the importance and priority of the research questions proposed by the technical experts, improving and broadening some of them, added new questions, and voiced their main concerns and views about AVB. Women helped to put the research questions into context in their communities, highlighted neglected factors/dimensions that influence practices and affect women\'s experience during labour and childbirth, underscored less salient consequences of AVB, and highlighted the main concerns of women about research on AVB. The consolidated vision of technical experts and women\'s representatives resulted in a technical brief published by WHO. The technical brief is expected to stimulate global research and action closely aligned with women\'s priorities.
    CONCLUSIONS: We describe a successful experience of engaging women, mostly from LMICs, in the identification of research gaps and needs to reintroduce AVB use. This process contributed to better aligning research questions with women\'s views, concerns, and priorities. Given the scarcity of reports about engaging women from LMICs to optimise research, this successful experience can serve as an inspiration for future work.
    UNASSIGNED: Women representatives were involved at every stage of the workshops described in full in this manuscript.

    妊娠期颅内恶性肿瘤的治疗对围手术期团队提出了独特的挑战。我们描述了一名28岁健康患者脑膜瘤的成功手术治疗,在她怀孕的第三个三个月,他第一次出现了全身性癫痫发作。对于妊娠期颅内恶性肿瘤的处理没有明确的指南,多学科方法对于为患者的癫痫发作和手术干预时机提供管理计划至关重要.激素介导的肿瘤生长是选择紧急手术干预的重要因素,我们讨论了当前将激素与妊娠肿瘤生长联系起来的证据。
    The management of intracranial malignancies in pregnancy poses unique challenges to the perioperative team. We describe the successful surgical management of a meningioma in a 28-year-old previously healthy patient, in her third trimester of pregnancy, who first presented with a generalised seizure. Without clear guidelines on the management of intracranial malignancies in pregnancy, a multidisciplinary approach was essential in providing a management plan for the patient\'s seizures and on the timing of her surgical intervention. Hormone-mediated tumour growth was a significant factor in opting for urgent surgical intervention and we discuss the current evidence linking hormones to tumour growth in pregnancy.

    怀孕存在风险,特别是对于有健康问题的女性。麻醉前咨询可以帮助预测这些风险,并在分娩当天建立医疗管理策略。虽然远程会诊在2019年冠状病毒病(COVID-19)大流行期间越来越受欢迎,关于怀孕期间麻醉前远程咨询的研究是有限的。这项研究旨在评估患者满意度和医师对妊娠晚期麻醉前咨询的远程咨询的看法。
    一项前瞻性观察性研究包括选择远程咨询的孕妇进行麻醉前咨询。使用Likert量表问题和系统使用量表评估患者满意度。使用Likert量表并在麻醉前评估中考虑麻醉技术的变化和临床数据的缺失来评估麻醉师的满意度。数据分析使用SPSSStatisticsforWindows,版本20.0。包括描述性统计,假设检验和比值比计算。这种方法探讨了患者和麻醉师满意度与相关风险因素之间的相关性。
    这项研究纳入了99名患者,85%的人对Likert量表表示满意和高度满意,88%的人认为远程会诊可接受系统使用量表(评分≥70)。麻醉师报告说,94%的病例对麻醉前的咨询感到满意。
    这项研究证明了远程医疗咨询在产科麻醉中的可行性和有效性,患者和麻醉师满意度高。
    UNASSIGNED: Pregnancy presents risks, particularly for women with pre-existing health problems. Pre-anaesthetic consultations can help anticipate these risks and establish a medical management strategy on the delivery day. While teleconsultations gained popularity during the coronavirus disease 2019 (COVID-19) pandemic, research on pre-anaesthetic teleconsultations during pregnancy is limited. This study aimed to assess patient satisfaction and physician perception of teleconsultations for third-trimester pre-anaesthetic consultations.
    UNASSIGNED: A prospective observational study included pregnant women who opted for teleconsultations for pre-anaesthetic consultations. Patient satisfaction was assessed using Likert scale questions and the System Use Scale. Anaesthetist satisfaction was evaluated using a Likert scale and by considering changes in anaesthetic techniques and missing clinical data in the pre-anaesthetic assessment. Data analysis utilised SPSS Statistics for Windows, Version 20.0. encompassing descriptive statistics, hypothesis testing and odds ratio calculations. This approach explored the correlation between patient and anaesthetist satisfaction and pertinent risk factors.
    UNASSIGNED: The study enroled 99 patients, with 85% expressing satisfaction and high satisfaction on the Likert scale and 88% finding the teleconsultation acceptable based on the System Use Scale (score ≥ 70). Anaesthetists reported being satisfied with the pre-anaesthetic consultations in 94% of cases.
    UNASSIGNED: This study demonstrates the feasibility and effectiveness of telemedicine consultations in obstetric anaesthesia, showing high patient and anaesthetist satisfaction rates.

    目的:量化产妇护理提供者在自然和手术阴道分娩(SVD和OVD)中会阴切开术与产科肛门括约肌损伤(OASI)之间关系的变化。
    方法:基于人群的回顾性队列研究加拿大无名氏定期分娩(2004-2015年)。使用对数二项回归来估计调整后的比率(ARR)和95%CI,以量化会阴切开术和OASI之间的关联。按护理提供者分层(产科医生[OB],家庭医生[FP],或注册助产士[RM]),同时调整潜在的混杂因素。
    结果:该研究包括631642例分娩。会阴切开术的使用因提供者而异:在SVDs中,会阴侧切率为19.6%,14.4%,在OB中为8.4%,FP,和RM组,分别。与没有会阴切开术的SVD相比,OASI的发生率更高(5.8%vs4.6%)。相反,与未进行手术的阴道分娩(16.7%)相比,进行会阴切开术的OASI发生率较低(15.3%)。在所有提供程序组中,OASI的ARR随SVD会阴切开术而增加,随会阴切开术和镊子分娩而减少.除了真空分娩外,提供者没有观察到这些关联的差异(ARR与会阴切开术没有,OB:0.88,95%CI0.84-0.92;FP:0.89,95%CI0.83-0.96,RM:1.22,95%CI1.02-1.48)。
    结论:在无效中,无论产妇护理提供者如何,SVD中会阴切开术与OASI呈正相关,会阴切开术与产钳分娩呈负相关.产妇护理提供者在真空分娩中修改了会阴切开术与OASI之间的关系。
    OBJECTIVE: To quantify variation in the association between episiotomy and obstetric anal sphincter injury (OASI) by maternity care provider in spontaneous and operative vaginal deliveries (SVDs and OVDs).
    METHODS: Population-based retrospective cohort study of vaginal, term deliveries among nullipara in Canada (2004-2015). Adjusted rate ratios (ARRs) and 95% CIs were estimated using log-binomial regression to quantify the associations between episiotomy and OASI, stratified by care provider (obstetrician [OB], family physician [FP], or registered midwife [RM]) while adjusting for potential confounders.
    RESULTS: The study included 631 642 deliveries. Episiotomy use varied by provider: among SVDs, the episiotomy rate was 19.6%, 14.4%, and 8.4% in the OB, FP, and RM groups, respectively. The rate of OASI was higher among SVDs with versus without episiotomy (5.8% vs 4.6%). Conversely, OASI occurred less frequently in operative vaginal deliveries with episiotomy (15.3%) compared with those without (16.7%). In all provider groups, the ARR for OASI was increased with episiotomy in SVD and decreased with episiotomy with forceps delivery. No differences in these associations were observed by provider except among vacuum delivery (ARR with episiotomy vs. without, OB: 0.88, 95% CI 0.84-0.92; FP: 0.89, 95% CI 0.83-0.96, RM: 1.22, 95% CI 1.02-1.48).
    CONCLUSIONS: In nullipara, irrespective of maternity care provider, there is a positive association between episiotomy and OASI among SVDs and an inverse association between episiotomy and deliveries with forceps. The relationship between episiotomy and OASI is modified by maternity care providers among vacuum deliveries.

    已提出将ESP阻滞(ESPB)和后腰四肌阻滞(pQLB)作为阿片类药物保留技术,用于管理腹部手术后的疼痛。在2021年12月至2022年10月之间,我们在FondazionePoliclinico大学AgostinoGemelliIRCCS的交付套件进行了一项回顾性比较研究,罗马,意大利,比较ESPB和pQLB预防选择性剖宫产(CS)术后疼痛的疗效。主要结果是前24小时的总吗啡消耗量。次要结果是首次阿片类药物请求时间;0、2、6、12和24小时的数字疼痛评定量表(NPRS);生命体征;不良事件。包括52名妇女。两组患者的吗啡总累积剂量没有显着差异(p=0.897)。第一剂吗啡的时间到了,两组NPRS值和血流动力学参数无统计学差异。在所考虑的不同时间间隔,NPRS值显著增加(p<0.001)。与pQLB组相比,ESPB组的吗啡抢救剂量需求较低(风险比为0.51,95%CI(0.27至0.95),p=0.030)。未报告不良事件。在CS后提供镇痛方面,ESPB似乎与pQLB一样有效。
    ESP block (ESPB) and posterior Quadratus Lumborum Block (pQLB) have been proposed as opioid-sparing techniques for the management of pain after abdominal surgery. Between December 2021 and October 2022, we conducted a retrospective comparative study at the delivery suite of Fondazione Policlinico Universitario Agostino Gemelli IRCCS, Rome, Italy, to compare the efficacy of ESPB and pQLB in preventing postoperative pain after an elective caesarean section (CS). The primary outcome was total morphine consumption in the first 24 h. Secondary outcomes were time to first opioid request; Numerical Pain Rating Scale (NPRS) at 0, 2, 6, 12 and 24 h; vital signs; adverse events. Fifty-two women were included. The total cumulative dose of morphine was not significantly different between the two groups of patients (p = 0.897). Time to first dose of morphine, NPRS values and haemodynamic parameters were not statistically different between the two groups. NPRS values significantly increased (p < 0.001) at the different time intervals considered. The need for rescue doses of morphine was lower in the ESPB group compared to the pQLB group (hazard ratio of 0.51, 95% CI (0.27 to 0.95), p = 0.030). No adverse event was reported. ESPB seems to be as effective as pQLB in providing analgesia after CS.

  • 文章类型: Randomized Controlled Trial
    背景:该研究旨在研究单次静脉注射艾氯胺酮对分娩镇痛后产后抑郁症(PPD)发生率的影响,并探讨潜在的机制。
    方法:选择120例硬膜外镇痛泵分娩镇痛的产妇,随机分为两组。试验组在胎儿脱离后静脉内注射剂量为0.2mg/kg的依维他明,对照组给予安慰剂。记录分娩后PPD的发生情况和副作用。在分娩镇痛前和24h测量与应激和炎症相关的一些指标,1周,在这项研究中,分娩后6周。数据采用独立t检验分析,SPSS软件(25.0版)重复测量方差分析和卡方检验。其被认为是统计学上显著的,因为p值小于0.05。
    结果:使用esketamine在分娩后一周和六周内,PPD的发生率均显着降低(3.4%vs.15.3%,p=0.004和5.2%vs.18.6%,分别为p=0.006)。本研究中不同时间点的应激和炎症相关指标也存在显著差异,而两组分娩后48h的副作用相似。
    结论:分娩后单次静脉注射艾氯胺酮可减少分娩后1周和6周产后抑郁症的发生。而副作用没有增加。艾氯胺酮的抗抑郁作用可能与减轻应激反应和炎症有关。
    背景:该试验于2022年5月30日在中国临床试验注册中心注册(CTRI注册号-ChiCTR2200060387)。注册表的URL:https://www。chictr.org.cn/bin/home.
    The study was designed to investigate effects of single intravenous injection of esketamine on the incidence of postpartum depression (PPD) after labor analgesia and explore the potential mechanisms.
    A total of 120 women who underwent labor analgesia by epidural analgesia pump were enrolled and divided into two groups randomly. Esketamine at a dose of 0.2 mg/kg was intravenously injected after fetal disengagement in the test group and placebo was administered in the control group. The occurrence of PPD and side effects after delivery were recorded. Some indicators related to stress and inflammation were measured before labor analgesia and at 24 h, 1 week, and 6 weeks after delivery in this study. Data were analyzed by independent t-test, repeated measures analysis of variance and Chi-square test in SPSS software (version 25.0). It was considered statistically significant since a p value less than 0.05.
    The incidence of PPD was significantly decreased both for one week and six weeks after delivery by using of esketamine (3.4% vs. 15.3%, p = 0.004 and 5.2% vs. 18.6%, p = 0.006, respectively). There were also significant differences between the stress and inflammation-related indicators in different time points in this study, while the side effects for 48 h after delivery were similar between the two groups.
    Single intravenous injection of esketamine after delivery in participants underwent labor analgesia can decrease the occurrence of postpartum depression for one week and six weeks after delivery, while the side effects were not increased. The antidepressant effects of esketamine may be related to the reduction of stress response and inflammation.
    The trial was registered at the Chinese Clinical Trial Registry on 5/30/2022 (CTRI registration number-ChiCTR2200060387). URL of registry: https://www.chictr.org.cn/bin/home .
