Objective

To analyse amniotic fluid volume (AFV), specifically oligohydramnios or polyhydramnios, and associated pregnancy and neonatal outcomes in twin gestations through systematic review and meta-analysis.

Methods

We utilised systematic review methodology to identify items within published and grey literature resources. Prospective and retrospective studies with a control group were included. Inclusion criteria were as follows: studies in English, twin pregnancy in which AFVs and associated pregnancy and/or neonatal outcomes were evaluated. Exclusion criteria included the presence of an anomalous fetus, chromosome abnormality, monochorionic diamniotic twin pregnancy complicated by twin–twin transfusion syndrome or twin-reversed arterial perfusion, twin gestations undergoing therapeutic interventions (i.e. fetoscopic laser photocoagulation and serial amniocentesis) and monochorionic monoamniotic twin pregnancy.

Results

The literature search identified 1068 abstracts, only four met criteria for inclusion and analysis. The pooled data (two studies per outcome) revealed no significant difference in rate of pre-term delivery (OR: 2.94; CI: 0.20–43.81), pre-term delivery less than 32 weeks (OR: 1.97; CI: 0.43–9.12), umbilical cord pH < 7 (OR: 2.66; CI: 0.22–32.51), rate of stillbirth (OR: 4.13; CI: 0.40–42.70), neonatal death (OR: 1.48; CI: 0.05–43.94), rate of NICU admission (OR: 1.38; CI: 0.61–3.11) or rate of small-for-gestational-age (SGA) infants (OR: 1.39; CI: 0.33–5.94).

Conclusion

Based on the pooled data (two studies per outcome), there was no difference in the fate of pre-term delivery, umbilical cord pH < 7, stillbirth, neonatal death or SGA infants. What is disturbing is the lack of studies (1946–2020) that analysed the association between AFV and pregnancy outcomes in twin pregnancies.

通过系统回顾和荟萃分析，分析双胎妊娠中羊水体积(AFV)，特别是羊水过少或羊水过多，以及相关的妊娠和新生儿结局。我们采用系统评价方法在已发表文献和灰色文献资源中确定项目。包括前瞻性和回顾性研究与对照组。纳入标准如下:英语研究，双胎妊娠，评估afv和相关妊娠和/或新生儿结局。排除标准包括异常胎儿、染色体异常、单绒毛膜双羊膜双胎妊娠合并双胎输血综合征或双胎动脉灌注逆转、接受治疗性干预(即胎儿镜激光光凝和连续羊膜穿刺术)的双胎妊娠和单绒毛膜单羊膜双胎妊娠。文献检索确定了1068篇摘要，只有4篇符合纳入和分析的标准。汇总数据(每个结果两项研究)显示早产率无显著差异(OR: 2.94;CI: 0.20-43.81)，早产小于32周(OR: 1.97;CI: 0.43-9.12)，脐带pH < 7 (OR: 2.66;CI: 0.22-32.51)，死产率(OR: 4.13;CI: 0.40-42.70)，新生儿死亡(OR: 1.48;CI: 0.05-43.94)，新生儿重症监护病房入院率(OR: 1.38;CI: 0.61-3.11)或小胎龄(SGA)婴儿的发生率(or: 1.39;置信区间:0.33—-5.94)。根据汇总的数据(每个结局两项研究)，早产、脐带pH < 7、死产、新生儿死亡或SGA婴儿的命运没有差异。令人不安的是，缺乏研究(1946-2020)分析双胎妊娠中AFV与妊娠结局之间的关系。

Purpose

To determine whether a 24 MHz transducer significantly improves sensitivity, specificity and accuracy in evaluating flexor tendon repair integrity compared with an 18 MHz transducer.

Methods

One hundred and twelve cadaveric digits were randomised to an intact repair or simulated ‘failed’ repair, and to a two- or eight-strand repair of a flexor digitorum profundus laceration. A blinded sonologist evaluated specimens in static mode using 18 and 24 MHz transducers. Gaps were remeasured after scanning, and final gap width recorded. McNemar's exact test calculated differences between sensitivity, specificity and accuracy, and chi-squared test to compare sensitivity, specificity and accuracy between number of strands (2 vs. 8) and repair gap (≥4 mm).

Results

The 24 MHz transducer had higher sensitivity (81 vs. 59%), lower specificity (67 vs. 70%) and higher overall accuracy (74 vs. 64%), than the 18 MHz transducer. The difference for sensitivity was significant (P = 0.011), but not differences for specificity and overall accuracy (P > 0.05). Pearson's correlation (r = 0.61) demonstrated a moderate-to-strong positive correlation between measured and true gap sizes. Increased number of suture strands (2 vs. 8) did not impair sensitivity, specificity nor accuracy.

Discussion

Ultrasound may tend to overestimate gap width, and a slight risk that some intact repairs, or those with small, clinically insignificant gaps may undergo surgical exploration that may not be indicated.

Conclusions

A 24 MHz transducer is a more sensitive and accurate transducer for assessing flexor tendon repair integrity and measuring small gaps.

要确定24 与18 MHz换能器相比，MHz换能器在评估屈肌腱修复完整性方面显著提高了灵敏度、特异性和准确性 MHz转换器。将112具尸体手指随机分为完整修复或模拟“失败”修复，以及指深屈肌撕裂伤的两股或八股修复。一位盲声学家使用18和24对静态模式下的样本进行了评估 MHz换能器。扫描后重新测量间隙，并记录最终间隙宽度。McNemar精确检验计算了敏感性、特异性和准确性之间的差异，卡方检验比较了链数（2对8）和修复间隙（≥4 mm）。24 与18MHz换能器相比，MHz换能器具有更高的灵敏度（81对59%）、更低的特异性（67对70%）和更高的总体准确度（74对64%）。敏感性差异有统计学意义（P = 0.011），但在特异性和总体准确性方面没有差异（P > 0.05）。Pearson相关性（r = 0.61）表明，测量的间隙大小与真实间隙大小之间存在中等到强烈的正相关性。缝合线股数的增加（2股对8股）并未损害敏感性、特异性和准确性。超声可能倾向于高估间隙宽度，以及一些完整的修复或那些具有较小、临床上不显著间隙的修复可能需要进行手术探查的轻微风险，这些手术探查可能不适用。A 24 MHz换能器是一种更灵敏、更准确的换能器，用于评估屈肌腱修复的完整性和测量小间隙。

Introduction/Purpose

Percutaneous core-needle biopsy of the testicle has been shown to be a safe and effective method of obtaining tissue for histological analysis and can be considered in specific clinical scenarios. While the use of spermatic cord block has been shown to be effective in pain relief in the emergent setting and as an anaesthetic option for inguinal surgery, its use in percutaneous core-needle biopsy has not been well described. Through this case series, we present our experience and technique of ultrasound-guided percutaneous core-needle biopsy using spermatic cord block in the setting of indeterminant testicular masses.

Methods

Our departmental biopsy database was reviewed to identify patients who underwent percutaneous core-needle biopsy of the testicle from March 2010 to July 2022 and who also received spermatic cord block during the procedure.

Results

Three patients were identified who met the search criteria. All three patients presented for the evaluation of indeterminant testicular mass and had a known non-testicular primary cancer diagnosis at the time of biopsy. All three biopsies were performed using a combination of spermatic cord block, moderate sedation, and local anaesthetic. Biopsies were obtained using an 18-gauge spring-loaded device with 4-5 core samples obtained during each procedure. All biopsies were well tolerated without significant pain or post-procedure complications.

Discussion

Ultrasound-guided percutaneous core-needle testicular biopsy using spermatic cord block is a safe and effective option in sampling indeterminate testicular masses while maintaining patient comfort.

Conclusion

The inclusion of a spermatic cord block in combination with local anaesthetic and moderate sedation has become standard practice in our institution, as we believe this maximises patient comfort and safety resulting in a better patient experience.

导言/目的经皮睾丸核心针活检已被证明是一种安全有效的获取组织进行组织学分析的方法，在特定的临床情况下可以考虑使用。虽然精索阻滞已被证明能有效缓解急诊环境下的疼痛，并可作为腹股沟手术的麻醉选择，但其在经皮穿刺活检中的应用尚未得到很好的描述。通过本病例系列，我们介绍了在超声引导下使用精索阻滞进行经皮核心穿刺活检的经验和技术，用于治疗不确定的睾丸肿块。方法我们对科室活检数据库进行了审查，以确定 2010 年 3 月至 2022 年 7 月期间接受经皮睾丸核心穿刺活检且在手术过程中接受了精索阻断的患者。结果找到了三名符合搜索标准的患者。这三位患者都是因睾丸肿块不确定而接受评估，并且在活检时已确诊为非睾丸原发性癌症。这三例活检均采用精索阻滞、中度镇静和局部麻醉相结合的方法进行。活检使用的是 18 号弹簧加载装置，每次取样 4-5 个核心样本。所有活组织检查的耐受性都很好，没有明显的疼痛或术后并发症。讨论使用精索阻断进行超声引导经皮穿刺睾丸活检是一种安全有效的方法，可用于取样不确定的睾丸肿块，同时还能保持患者的舒适度。结论结合局部麻醉和中度镇静剂进行精索阻滞已成为我院的标准做法，因为我们相信这能最大限度地提高患者的舒适度和安全性，从而为患者带来更好的体验。

Pseudoaneurysms are frequent vascular anomalies. This review article aims to describe the unique specific aspect of pseudoaneurysm (PSA) that allows to make the diagnosis using different modalities: colour Doppler ultrasound, computed tomographic angiography, magnetic resonance angiography and conventional angiography. It is essential to know the various aetiologies of PSA: iatrogenic, traumatic, dissecting and anastomotic; different locations and the possible complications, information to help clinicians choose the best treatment. Our review is supported by illustrated series of cases.

假性动脉瘤是一种常见的血管畸形。这篇综述文章旨在描述假性动脉瘤（PSA）的特殊性，以便使用不同的方法进行诊断：彩色多普勒超声、计算机断层扫描血管造影、磁共振血管造影和传统血管造影。了解 PSA 的各种病因至关重要：先天性、外伤性、解剖性和吻合性；不同的位置和可能的并发症，这些信息有助于临床医生选择最佳治疗方法。图文并茂的系列病例为我们的综述提供了佐证。

Introduction

During pregnancy, the umbilical cord attaches to the placenta in a central, eccentric, marginal or velamentous location. Maternal and fetal complications are associated with marginal and velamentous cord insertions, the most clinically significant being perinatal mortality due to undiagnosed vasa praevia. Current literature describes a wide variation regarding regulation of placental cord insertion (PCI) documentation during antenatal ultrasound examinations. This prospective cross-sectional study aimed to assess the current practice of antenatal PCI documentation in Australia.

Methods

Members of the Australian Sonographer Accreditation Registry were invited to participate in an online survey which was distributed between February and March 2022.

Results

Four hundred ninety sonographers met the inclusion criteria for the study of which 330 (67.3%) have more than 10 years' experience as a sonographer and 375 (76.5%) are employed primarily in a public or private setting offering general ultrasound. Most respondents (89.6%) indicated documentation of the PCI site is departmental protocol at the second trimester anatomy scan (17–22 weeks gestation), but PCI documentation is protocol in less than 50% of other obstetric ultrasound examinations listed in the survey. The PCI site is included in the formal ultrasound report at a rate significantly less than inclusion in the departmental protocol and the sonographer's worksheet.

Conclusions

Considering the potential maternal and fetal complications associated with abnormal PCI and the ease at which the PCI site is identified in the first and second trimesters, we believe that standard inclusion of the PCI site in departmental protocol and in the formal ultrasound report from 11 weeks gestation, regardless of whether it is normal or abnormal, would prove invaluable.

在怀孕期间，脐带以中心、偏心、边缘或膜状位置附着在胎盘上。产妇和胎儿并发症与边缘和膜状脐带插入有关，最重要的临床意义是由于未确诊的前置血管引起的围产期死亡率。目前的文献描述了在产前超声检查中关于胎盘脐带插入(PCI)文件的调节的广泛差异。这项前瞻性横断面研究旨在评估澳大利亚产前PCI记录的当前实践。方法邀请澳大利亚超声医师认证注册中心的成员参加2022年2月至3月的在线调查。结果490名超声师符合纳入标准，其中330名(67.3%)具有10年以上超声工作经验，375名(76.5%)主要就职于提供普通超声的公共或私人机构。大多数回答者(89.6%)表示，在妊娠中期解剖扫描(妊娠17-22周)时，PCI部位的记录是部门协议，但在调查中列出的其他产科超声检查中，PCI记录是不到50%的协议。PCI部位被纳入正式超声报告的比率明显低于纳入部门方案和超声医师工作表的比率。结论:考虑到PCI异常可能引起的母胎并发症，以及在妊娠早期和中期发现PCI部位的难度，我们认为，将PCI部位标准纳入部门方案和妊娠11周的正式超声报告，无论其是否正常，都是非常宝贵的。

Point-of-care ultrasonography—An essential skill for medical graduates? 护理点超声检查——医学毕业生的必备技能？

Q3 Medicine

Australasian Journal of Ultrasound in Medicine

Pub Date : 2023-07-23 DOI: 10.1002/ajum.12355

Konstantin Yastrebov, Cartan Costello, Ben Taylor, Adrienne Torda

The recent proliferation of point-of-care ultrasonography (POCUS) in the clinical practice of many medical specialties has exposed persistent barriers to education, training and standardisation. Specialist training curriculums are already overwhelming, having grossly insufficient time available for the specialist trainees and for the small number of available trainers alike to incorporate POCUS into postgraduate education. The logical solution to overcome these barriers could be to incorporate basic POCUS education and training into the undergraduate university curriculums, introducing longitudinal integration with other relevant medical sciences. The Australasian Society of Ultrasound in Medicine already has well-established educational programmes in POCUS with standardised assessment of competency, which could potentially offer the basis for symbiosis with the Australian and New Zealand medical schools.

近来，护理点超声造影术（POCUS）在许多医学专科的临床实践中得到广泛应用，这暴露出教育、培训和标准化方面长期存在的障碍。专科培训课程已经不堪重负，无论是专科学员还是为数不多的培训师，都没有足够的时间将 POCUS 纳入研究生教育。克服这些障碍的合理解决方案是将 POCUS 基础教育和培训纳入大学本科课程，并与其他相关医学科学进行纵向整合。澳大拉西亚医学超声学会已经制定了完善的 POCUS 教育计划，并对能力进行标准化评估，这有可能为与澳大利亚和新西兰医学院的合作奠定基础。

Introduction/Purpose

Peripheral intravenous catheter (PIVC) insertion can be challenging in children, with point-of-care ultrasound (POCUS) known to increase success rates. The objective of this study was to survey how emergency department (ED) clinicians identify and escalate paediatric patients with difficult intravenous access (DIVA), specifically the use of POCUS.

Methods

This cross-sectional study was conducted in an Australian academic mixed ED that surveyed resident medical officers (RMOs), registrars, consultants and senior paediatric nurses. A 15 multiple-choice questionnaire evaluated clinicians experience with paediatric PIVC insertion, approach to identifying and managing DIVA and the use of POCUS or other adjuncts.

Results

Eighty clinicians (34.2% response rate) completed the survey. Poor vein palpability was rated the highest predictor of DIVA. Of the respondents, 19 consultants (86.4%), 28 registrars (90.3%) and 16 RMOs (64.0%) used POCUS as an adjunct for paediatric DIVA patients but 16 consultants (72.8%), 21 registrars (67.8%) and 20 RMOs (80.0%) would use this less than 25% of the time in clinical practice.

Discussion

This survey suggests more clinicians to prefer using objective factors when identifying paediatric DIVA patients, rather than subjectively using gestalt, which relies on clinician experience. Whilst clearly recognised as a useful tool in our study, POCUS was used infrequently for paediatric DIVA patients.

Conclusions

There is currently no consistent process for the identification and escalation of paediatric DIVA patients, including the use of adjuncts such as POCUS. Clinician awareness for these issues should be addressed, which should include the development of guidelines and clinician training in POCUS for PIVC insertion in children.

导读/目的外周静脉导管(PIVC)的插入对儿童来说是一项挑战，而定点超声(POCUS)可以提高成功率。本研究的目的是调查急诊科(ED)临床医生如何识别和升级静脉注射困难(DIVA)的儿科患者，特别是POCUS的使用。方法横断面研究在澳大利亚的一个学术混合急诊科进行，调查了住院医疗官员(RMOs)、登记员、顾问和高级儿科护士。一份15项多项选择问卷评估了临床医生在儿科PIVC插入、DIVA识别和管理方法以及POCUS或其他辅助手段的使用方面的经验。结果完成调查的临床医生80名，有效率34.2%。静脉触感差被认为是DIVA的最高预测因子。在应答者中，19名会诊医生(86.4%)、28名注册医生(90.3%)和16名注册医生(64.0%)使用POCUS作为儿科DIVA患者的辅助手段，但16名会诊医生(72.8%)、21名注册医生(67.8%)和20名注册医生(80.0%)在临床实践中使用POCUS的时间少于25%。本调查提示更多的临床医生在识别儿科DIVA患者时更倾向于使用客观因素，而不是主观地使用格式塔，它依赖于临床医生的经验。虽然POCUS在我们的研究中被明确认为是一种有用的工具，但它很少用于儿科DIVA患者。结论:目前没有一致的流程来识别和升级儿科DIVA患者，包括使用POCUS等辅助手段。应提高临床医生对这些问题的认识，其中应包括制定儿童PIVC植入POCUS的指南和临床医生培训。

Introduction/Purpose

To determine the location of the rectus femoris (RF) motor branch nerve, as well as its coordinates with reference to anatomical and ultrasound landmarks.

Methods

Thirty chronic stroke patients with stiff knee gait (SKG) and RF hyperactivity were included. The motor nerve branch to the RF muscle was identified medially to the vertical line from anterior superior iliac spine and the midpoint of the superior margin of the patella (line AP) and vertically to the horizontal line from the femoral pulse and its intersection point with the line AP (line F). The point of the motor branch (M) was located with ultrasound, and nerve depth and subcutaneous tissue thickness (ST) were calculated.

Results

The coordinates of the motor branch to the RF were 2.82 (0.47) cm medially to the line AP and 4.61 (0.83) cm vertically to the line F. Nerve depth and subcutaneous tissue thickness were 2.71 (0.62) cm and 1.12 (0.75) cm, respectively.

Conclusion

The use of specific coordinates may increase clinicians' confidence when performing RF motor nerve block. This could lead to better decision-making when assessing SKG in chronic stroke patients.

Transient intussusception – What the sonographer needs to know 短暂性肠套叠-超声医师需要知道的

Q3 Medicine

Intussusception is typically considered an acute emergency; however, the increased utilisation of medical imaging has revealed that intussusceptions can also be transient, asymptomatic and possibly physiologic. Sonographers should be aware of three categories of intussusceptions: (i) persistent intussusceptions resulting in acute abdomen and requiring urgent intervention, (ii) transient symptomatic intussusceptions which may be amenable to a ‘wait-and-see’ strategy and (iii) transient asymptomatic intussusceptions which almost always involve the small bowel. In particular, the incidental discovery of enteroenteric intussusceptions in children should not be confused with acute pathology. In adults, sonographers should be mindful of the frequent presence of pathological lead points and further investigations may be warranted. In this literature review, we provide an overview of transient intussusceptions, highlight important differences between children and adults and describe sonographic appearances of various intussusceptions and their mimics.

肠套叠通常被认为是急性急症;然而，越来越多的医学影像显示，肠套叠也可能是短暂的、无症状的，也可能是生理性的。超声检查人员应注意三类肠套叠:(i)持续性肠套叠导致急腹症，需要紧急干预;(ii)一过性症状性肠套叠，可采取“观望”策略;(iii)一过性无症状肠套叠，几乎总是涉及小肠。特别是，偶然发现的肠肠套叠的儿童不应与急性病理混淆。在成人中，超声检查人员应注意经常出现的病理导点，并可能需要进一步的调查。在这篇文献综述中，我们概述了短暂性肠套叠，强调了儿童和成人之间的重要区别，并描述了各种肠套叠及其模拟的超声表现。
