Calcium channel blocker (CCB) toxicity carries a high mortality and is the sixth most fatal drug class reported to US poison centers. Amlodipine overdose is characterized by a life-threatening arterial vasodilation that compromises organ perfusion. The management of CCB intoxication is focused on maintaining adequate organ perfusion. In cases refractory to medical therapies, hemodynamic support with extracorporeal membrane oxygenation (ECMO) is warranted necessitating higher flows than usual to compensate for the vasodilation and requiring central cannulation. We present a case of a 12-year-old with severe dihydropyridine CCB ingestion, refractory to medical management and successfully treated with central ECMO cannulation. The patient was discharged home with no significant disability. Central ECMO cannulation may be helpful to facilitate adequate flows in vasodilatory shock such as CCB overdose.

钙通道阻滞剂(CCB)中毒的死亡率很高,是美国毒物中心接报的第六大致命药物类别。氨氯地平用药过量的特点是动脉血管扩张,损害器官灌注,危及生命。处理氯苯类药物中毒的重点是维持足够的器官灌注。在药物治疗无效的病例中,需要使用体外膜肺氧合(ECMO)进行血流动力学支持,这需要比平时更高的血流量来补偿血管扩张,并需要中心插管。我们介绍了一例严重摄入二氢吡啶类氯苯(CCB)的 12 岁患者的病例。患者出院回家后无明显残疾。中心 ECMO 插管可能有助于促进血管扩张性休克(如氯苯类药物过量)患者获得充足的血流。

Background Access to quality healthcare education across the world is disproportionate. This study explores the potential for health professions education to be delivered online to reach international students. Methods Exploratory mixed methods were used to identify the barriers, facilitators, and early outcomes of online international health professions education. Results Qualitative analysis yielded four primary and nine subthemes. Multiple interventions were implemented in the planning of a novel online international Extracorporeal Science (ECS) program based on these themes. Quantitative data from the first semester of the ECS program was collected along with data from the traditional entry-level program and historic data from previous entry-level cohorts. No significant correlations or differences were found between students. Student satisfaction surveys were determined to be equivalent for each group. Mixed data analysis revealed exceptional student satisfaction in areas where qualitative feedback was incorporated in the program design. Conclusions Online international education may be a viable option in the health professions. Barriers and facilitators to this mode of education were identified and utilized in designing one such program. Early outcomes from the novel ECS program reveal that the student performance and satisfaction are equivalent to those of a traditional in-person training program.

Extracorporeal Cardiopulmonary Resuscitation (ECPR) is an emerging approach to cardiac arrest. We present two contrasting cases from a high-volume extracorporeal membrane oxygenation (ECMO) center (defined as greater than 30 ECMO cases per year) without a 24/7 ECPR program to highlight how to establish an ECPR program with a focus on patient selection and outcome optimization. In one case, a patient presented with cardiac arrest during initial triage for chest pain within the emergency department, and in the other case, a patient experienced an out-of-hospital cardiac arrest with prolonged no-flow and low-flow time. Despite the lack of a 24/7 ECPR program at the presenting center, both patients received an ECPR evaluation, as both patients presented while all services necessary for ECMO cannulation were available. The in-hospital cardiac arrest patient was successfully cannulated for ECMO during cardiopulmonary resuscitation and survived with few complications. The out-of-hospital cardiac arrest patient was deemed a poor candidate for ECPR and expired soon after presentation. These two cases highlight the complex decision-making in ECPR and further illustrate how to create ECPR protocols at a high-volume ECMO center before resources are available for 24/7 ECPR program.
体外心肺复苏(ECPR)是一种新兴的心脏骤停方法。我们介绍了来自大容量体外膜氧合(ECMO)中心的两个对比病例(定义为每年超过30例ECMO病例),没有24/7 ECPR计划,以强调如何建立ECPR计划,重点是患者选择和结果优化。在一个病例中,一名患者在急诊室进行胸痛初步分诊时出现心脏骤停,而在另一个病例中,一名患者出现院外心脏骤停,无血流和低血流时间延长。尽管在主诊中心缺乏24/7 ECPR项目,但两名患者都接受了ECPR评估,因为两名患者都是在ECMO插管所需的所有服务可用的情况下就诊的。该住院心脏骤停患者在心肺复苏期间成功插管ECMO,存活,并发症少。院外心脏骤停患者被认为不适合进行ECPR,并在就诊后不久死亡。这两个案例突出了ECPR中的复杂决策,并进一步说明了如何在资源可用之前在大容量ECMO中心创建ECPR协议。

Background: A standard blood prime for cardiopulmonary bypass (CPB) in congenital cardiac surgery may possess non-physiologic values for electrolytes, glucose, and lactate. Pre-bypass Ultrafiltration (PBUF) can make these values more physiologic and standardized prior to bypass initiation. We aimed to determine if using PBUF on blood primes including packed red blood cells and thawed plasma would make prime values more predictable and physiologic. Additionally, we aimed to evaluate whether the addition of PBUF had an impact on outcome measures. Methods: Retrospective review of consecutive patients ≤ 1 year of age undergoing an index cardiac operation on CPB between 8/2017-9/2021. As PBUF was performed at the perfusionists’ discretion, a natural grouping of patients that received PBUF vs. those that did not occurred. Differences in electrolytes, glucose, and lactate were compared at specific time-points using Fisher’s exact test for categorical variables and the Wilcoxon rank sum test for continuous variables. Clinical outcomes were also assessed. Results: In both cohorts, the median age at surgery was 3 months and 47% of patients were female; 308/704 (44%) of PBUF group and 163/414 (39%) of the standard prime group had at least one preoperative risk factor. The proportion of PBUF circuits which demonstrated more physiologic values for glucose (318 [45%]), sodium (434, [62%]), potassium (688 [98%]), lactate (612 [87%]) and osmolality (595 [92%]) was significantly higher when compared to standard prime circuit levels for glucose (8 [2%]), sodium (13 [3%], potassium (150 [36%]), lactate (56 [13%]) and osmolality (23 [6%]) prior to CPB initiation. There were no differences in clinical outcomes or rates of major adverse events between the two cohorts. Conclusions: PBUF creates standardized and more physiologic values for electrolytes, glucose, and lactate before the initiation of bypass without significant impacts on in-hospital outcomes.
背景:先天性心脏手术中体外循环(CPB)的标准血源可能具有电解质、葡萄糖和乳酸的非生理性值。预旁路超滤(PBUF)可以使这些值在旁路启动之前更加生理性和标准化。我们的目的是确定使用PBUF对血液质点(包括包装红细胞和解冻血浆)是否会使质点值更具可预测性和生理性。此外,我们的目的是评估PBUF的加入是否对结果测量有影响。方法:回顾性分析2017年8月至2021年9月期间连续接受CPB指数心脏手术的≤1岁患者。由于PBUF是在灌注师的判断下进行的,因此接受PBUF的患者与未接受PBUF的患者自然分组。在特定时间点比较电解质、葡萄糖和乳酸的差异,使用分类变量的Fisher精确检验和连续变量的Wilcoxon秩和检验。临床结果也进行了评估。结果:在两个队列中,手术时的中位年龄为3个月,47%的患者为女性;PBUF组308/704例(44%)和标准prime组163/414例(39%)存在至少一种术前危险因素。与CPB启动前的葡萄糖(8[2%])、钠(13[3%])、钾(688[98%])、乳酸(612[87%])和渗透压(595[92%])的标准初始回路水平相比,PBUF回路中葡萄糖(8[2%])、钠(13[3%])、钾(150[36%])、乳酸(56[13%])和渗透压(23[6%])的生理值更高。两组患者的临床结果和主要不良事件发生率均无差异。结论:PBUF在搭桥术开始前为电解质、葡萄糖和乳酸盐创造了标准化和更生理的值,对住院结果没有显著影响。

The surgical management of prosthetic valvular endocarditis (PVE) can be challenging. We report a case of a 46-year-old female patient who had a history of four cardiac operations. We chose a mitral valve replacement via right thoracotomy to enables optimal exposure of mitral valve (MV). Because of multi-reoperations, we employed systemic hyperkalemia for cardiac arrest to protect heart during cardiopulmonary bypass (CPB) without aortic cross-clamping. Here, we present a complex operation that performed management of CPB under hyperkalemia and the patient had a good postoperative recovery.
人工瓣膜心内膜炎(PVE)的外科治疗具有挑战性。我们报告一个46岁的女性病人,她有四次心脏手术的历史。我们选择通过右开胸进行二尖瓣置换术,以实现二尖瓣(MV)的最佳暴露。由于多次再手术,我们采用全身高钾血症治疗心脏骤停,以保护体外循环(CPB)期间无主动脉交叉夹紧的心脏。在这里,我们提出了一个复杂的手术,在高钾血症下进行了CPB的管理,患者术后恢复良好。

Background: Extracorporeal membrane oxygenation (ECMO) is a cardiopulmonary bypass device that provides life-saving complete respiratory and cardiac support in patients with cardiorespiratory failure. The majority of drugs prescribed to patients on ECMO lack dosing strategy optimized for ECMO patients. Several studies demonstrated that dosing is different in this population because the ECMO circuit components can adsorb drugs and affect drug exposure substantially. Saturation of ECMO circuit components by drug disposition has been posited but has not been proven. In this study, we have attempted to determine if propofol adsorption is saturable in ex vivo ECMO circuits. Methods: We injected ex vivo ECMO circuits with propofol, a drug that is highly adsorbed to the ECMO circuit components. Propofol was injected as a bolus dose (50 µg/mL) and a continuous infusion dose (6 mg/hr) to investigate the saturation of the ECMO circuit. Results: After the bolus dose, only 27% of propofol was recovered after 30 minutes which is as expected. However, >80% propofol was recovered after the infusion dose which persisted even when the infusion dose was discontinued. Conclusion: Our results suggest that if ECMO circuits are dosed directly with propofol, drug adsorption can be eliminated as a cause for altered drug exposure.
背景:体外膜氧合(ECMO)是一种体外循环装置,可为心肺衰竭患者提供完全的呼吸和心脏支持。大多数给ECMO患者开的药物缺乏针对ECMO患者优化的给药策略。几项研究表明,在这一人群中,剂量不同,因为ECMO电路组件可以吸附药物并显著影响药物暴露。ECMO电路元件饱和的药物配置已被假设,但尚未得到证实。在这项研究中,我们试图确定异丙酚的吸附是否在体外ECMO电路中是饱和的。方法:向体外ECMO回路注射异丙酚,异丙酚是一种高度吸附在ECMO回路元件上的药物。采用大剂量异丙酚(50µg/mL)和连续输注剂量(6 mg/hr)观察ECMO回路的饱和度。结果:给药30 min后异丙酚仅恢复27%,符合预期。然而,80%的异丙酚在输注剂量后恢复,即使停止输注剂量也持续存在。结论:我们的研究结果表明,如果ECMO回路直接给药异丙酚,药物吸附可以消除药物暴露改变的原因。
