Since extracorporeal membrane oxygenation (ECMO) was introduced as a treatment modality for respiratory failure in 1972 by Hill et al.,[1] it has provided support to patients with inadequate oxygen delivery for days to weeks. Clinicians have used ECMO to increase oxygen delivery in severe lung disease, ineffective cardiac output from circulatory failure, or combined cardiopulmonary failure. ECMO has typically been applied in rescue situations that were refractory to conventional therapy.[2] Recently, researchers in the U.S., Germany, and Taiwan reported a rapid increase in the use of ECMO in their countries.[3-5] Diseases such as the H1N1 pandemic influenza,[6] the development of ECMO technology,[7] and the publication of randomized clinical trials have likely contributed to an increase in the use of ECMO.[8] In contrast to the growing worldwide use of ECMO, evidence of its use in critical care situations is still lacking.[9] In particular, there is not much evidence supporting ECMO use in adult patients with Acute Respiratory Distress Syndrome (ARDS) and there is a paucity of rigorous experiments on its use in these patients.[10] Only 4 randomized clinical trials on the use of extracorporeal life support in ARDS have been previously reported.[11-14] Most of the existing publications on ECMO use are observational studies of a retrospective review, clinical experiences, and clinical reports. Last year, the Korean Journal of Critical Care Medicine (KJCCM) published 11 papers which described the use of ECMO. Most of them were clinical reports of various clinical situations related to ECMO use, and one publication was an original article of a retrospective review. Publications such as clinical or case reports may not provide direct evidence, however they can provide important information and influence clinicians to consider new or different treatments in certain clinical situations. This issue of KJCCM includes two new case reports on the use of ECMO. The first case report describes a transient complication of ECMO that was corrected in a neonate,[15] and the second is a case on ECMO use in aspiration pneumonia in a single lung.[16] Both cases are conceivable situations for clinicians similar to previous case reports published in this journal. A key question is how to organize such case reports or series so that they provide findings that are close to evidence. To cite one example, ECMO complications can arise either from patient factors or ECMO circuit components. Due to the diversity in indi-
自1972年Hill等人提出体外膜氧合(extracorporeal membrane oxygenation, ECMO)作为一种治疗呼吸衰竭的方法以来[1],ECMO为缺氧患者提供了数天至数周的支持。临床医生已经使用ECMO来增加严重肺部疾病、循环衰竭引起的心输出量无效或合并心肺衰竭的氧气输送。ECMO通常应用于常规治疗难治性的抢救情况。[2]最近,美国、德国和台湾的研究人员报告称,ECMO的使用在他们的国家迅速增加。[3-5] H1N1大流行性流感等疾病,[6]ECMO技术的发展,[7]以及随机临床试验的发表都可能导致ECMO使用的增加[8]。与ECMO在全球范围内日益增长的使用相比,其在重症监护情况下使用的证据仍然缺乏。[9]特别是,没有太多证据支持ECMO用于急性呼吸窘迫综合征(ARDS)的成年患者,并且缺乏在这些患者中使用ECMO的严格实验。[10]在ARDS中使用体外生命支持的随机临床试验之前只有4个报道。[11-14]关于ECMO使用的现有出版物大多是回顾性回顾、临床经验和临床报告的观察性研究。去年,韩国重症医学杂志(KJCCM)发表了11篇描述ECMO使用的论文。其中大多数是与ECMO使用相关的各种临床情况的临床报告,其中一篇是回顾性综述的原创文章。临床或病例报告等出版物可能不能提供直接证据,但它们可以提供重要信息,并影响临床医生在某些临床情况下考虑新的或不同的治疗方法。这一期的KJCCM包括两个关于ECMO使用的新病例报告。第一个病例报告描述了ECMO的一过性并发症,该并发症在新生儿中得到纠正[15],第二个病例是ECMO在单肺吸入性肺炎中的应用[16]。对于临床医生来说,这两种情况与本杂志上发表的先前病例报告相似。一个关键问题是如何组织这些案例报告或系列,使它们提供接近证据的发现。举一个例子,ECMO并发症可以由患者因素或ECMO电路元件引起。由于印度的多样性

Although shock in sepsis is usually managed successfully by conventional medical treatment, a subset of cases do not respond and may require salvage therapies such as veno-arterial extracorporeal membrane oxygenation (VA ECMO) support as well as an attempt to remove endotoxins. However, there are limited reports of attempts to remove endotoxins in patients with septic shock on VA ECMO support. We recently experienced a case of septic shock with severe myocardial injury whose hemodynamic improvement was unsatisfactory despite extracorporeal membrane oxygenation (ECMO) support. Since the cause of sepsis was acute pyelonephritis and blood cultures grew gram-negative bacilli, we additionally applied polymyxin B direct hemoperfusion (PMX-DHP) to the ECMO circuit and were able to successfully taper off vasopressors and wean off ECMO support. To the best of our knowledge, this is the first adult case in which PMX-DHP in addition to ECMO support was successfully utilized in a patient with septic shock. This case indicates that additional PMX-DHP therapy may be beneficial and technically feasible in patients with septic shock with severe myocardial injury refractory to ECMO support.
虽然败血症休克通常可以通过常规药物治疗成功控制,但部分病例没有反应,可能需要补救性治疗,如静脉-动脉体外膜氧合(VA ECMO)支持以及尝试清除内毒素。然而,在VA ECMO支持下,脓毒性休克患者试图去除内毒素的报道有限。我们最近经历了一个脓毒性休克合并严重心肌损伤的病例,尽管体外膜氧合(ECMO)支持,但其血流动力学改善并不令人满意。由于脓毒症的病因是急性肾盂肾炎,血液培养物生长革兰氏阴性杆菌,我们在ECMO回路中添加了多粘菌素B直接血液灌流(PMX-DHP),并能够成功地逐渐减少血管加压剂并脱离ECMO支持。据我们所知,这是第一例在体外膜肺支持下成功应用PMX-DHP治疗感染性休克的成人病例。本病例表明,在ECMO支持难治性严重心肌损伤的脓毒性休克患者中,额外的PMX-DHP治疗可能是有益的,在技术上也是可行的。

Severe hyperammonemia can occur as a result of inherited or acquired liver enzyme defects in the urea cycle, among which ornithine transcarbamylase deficiency (OTCD) is the most common form. We report a very rare case of a 45-year-old Korean male who was admitted to the intensive care unit (ICU) due to severe septic shock with acute respiratory failure caused by Pneumocystis jiroveci pneumonia. During his ICU stay with ventilator care, the patient suffered from marked hyperammonemia (>1,700 μg/dL) with abrupt mental change leading to life-threatening cerebral edema. Despite every effort including continuous renal replacement therapy and use of a molecular adsorbent recirculating system (extracorporeal liver support-albumin dialysis) to lower his serum ammonia level, the patient was not recovered. The lethal hyperammonemia in the patient was later proven to be a manifestation of acquired liver enzyme defect known as OTCD, which is triggered by serious catabolic conditions, such as severe septic shock with acute respiratory failure.
严重的高氨血症可由于尿素循环中遗传或获得性肝酶缺陷而发生,其中鸟氨酸转氨基甲酰基酶缺乏症(OTCD)是最常见的形式。我们报告一个非常罕见的病例,45岁的韩国男性因严重感染性休克并急性呼吸衰竭而被送入重症监护病房(ICU)。患者在ICU重症监护期间出现明显的高氨血症(> 1700 μg/dL),伴有突发性精神变化,导致危及生命的脑水肿。尽管进行了各种努力,包括持续的肾脏替代治疗和使用分子吸附剂再循环系统(体外肝脏支持-白蛋白透析)来降低他的血清氨水平,但患者没有康复。患者的致命性高氨血症后来被证明是获得性肝酶缺陷(OTCD)的一种表现,它是由严重的分解代谢条件引发的,如严重感染性休克合并急性呼吸衰竭。

Opioid-induced chest wall rigidity is an uncommon complication of opioids. Because of this, it is often difficult to make a differential diagnosis in a mechanically ventilated patient who experiences increased airway pressure and difficulty with ventilation. A 76-yearold female patient was admitted to the intensive care unit (ICU) after surgery for periprosthetic fracture of the femur neck. On completion of the surgery, airway pressure was increased, and oxygen saturation fell below 95% after a bolus dose of fentanyl. After ICU admission, the same event recurred. Manual ventilation was immediately started, and a muscle relaxant relieved the symptoms. There was no sign or symptom suggesting airway obstruction or asthma on physical examination. Early recognition and treatment should be made in a mechanically ventilated patient experiencing increased airway pressure in order to prevent further deterioration.
阿片类药物引起的胸壁僵硬是一种罕见的阿片类药物并发症。正因为如此,对于气道压力增加和通气困难的机械通气患者,通常很难做出鉴别诊断。一位76岁女性患者因股骨颈假体周围骨折手术后住进重症监护病房。手术完成后,气道压力升高,芬太尼大剂量后氧饱和度降至95%以下。入住ICU后,同一事件再次发生。立即开始人工通气,并使用肌肉松弛剂缓解症状。体格检查未发现呼吸道阻塞或哮喘的体征或症状。机械通气患者出现气道压力升高时,应及早识别和治疗,以防止病情进一步恶化。

Pnuemocystis jirovecii pneumonia (PJP) is one of leading causes of acute respiratory failure in patients infected with human immunodeficiency virus (HIV), and the mortality rate remains high in mechanically ventilated HIV patients with PJP. There are several reported cases who received extracorporeal membrane oxygenation (ECMO) treatment for respiratory failure associated with severe PJP in HIVinfected patients. We report a patient who was newly diagnosed with HIV and PJP whose condition worsened after highly active antiretroviral therapy (HAART) initiation and progressed to acute respiratory distress syndrome requiring veno-venous ECMO. The patient recovered from PJP and is undergoing treatment with HAART. ECMO support can be an effective life-saving salvage therapy for acute respiratory failure refractory to mechanical ventilation following HAART in HIV-infected patients with severe PJP.
耶洛韦氏肺囊虫肺炎(PJP)是人类免疫缺陷病毒(HIV)感染患者急性呼吸衰竭的主要原因之一,机械通气的PJP患者死亡率仍然很高。有几例报告的病例接受体外膜氧合(ECMO)治疗的呼吸衰竭与严重PJP的hiv感染患者。我们报告了一位新诊断为HIV和PJP的患者,其病情在高活性抗逆转录病毒治疗(HAART)开始后恶化,并发展为急性呼吸窘迫综合征,需要静脉-静脉ECMO。患者从PJP中恢复,正在接受HAART治疗。ECMO支持对于hiv感染的严重PJP患者HAART后机械通气难治性急性呼吸衰竭是一种有效的挽救生命的治疗方法。

Diffuse alveolar hemorrhage (DAH) is associated with severe outcomes. We report a case of acute respiratory failure that required mechanical ventilation and was clinically and pathologically diagnosed as DAH related to exposure to organic dust. A 39-year-old man, who had visited a warehouse to grade beans for purchase, was referred to our hospital for impending respiratory failure. His initial radiographic examinations revealed diffuse bilateral ground-glass opacities in his lungs and bronchoalveolar lavage resulted in progressively bloodier returns, which is characteristic of DAH. He underwent bedside open lung biopsy of his right lower lobe in the intensive care unit. Biopsy results revealed DAH and organization with accumulation of hemosiderin-laden macrophages and a few fibroblastic foci. The patient was treated with empirical antibiotics and high-dose corticosteroids and successfully weaned from mechanical ventilation. DAH might be considered in the differential diagnosis of patients with acute respiratory failure after exposure to organic particles.
弥漫性肺泡出血(DAH)与严重的预后相关。我们报告一例需要机械通气的急性呼吸衰竭,临床和病理诊断为与暴露于有机粉尘有关的DAH。一名39岁男子,曾到仓库分级购买豆子,因即将发生呼吸衰竭而被转介到我们医院。他最初的x线检查显示双侧肺弥漫性磨玻璃影,支气管肺泡灌洗导致进行性出血,这是DAH的特征。他在重症监护室接受了床边的右下肺叶开放性肺活检。活检结果显示DAH和组织积聚含铁血黄素巨噬细胞和一些成纤维细胞灶。患者给予经验性抗生素和大剂量皮质类固醇治疗,并成功脱离机械通气。有机颗粒暴露后急性呼吸衰竭患者的鉴别诊断可考虑DAH。

In the spring of 2011, a cluster of lung injuries caused by humidifier disinfectant (HD) usage were reported in Korea. Many patients required mechanical ventilation, extracorporeal membrane oxygenation, and even lung transplantation (LTPL). However, the long-term course of HD-associated lung injury remains unclear because the majority of survivors recovered normal lung function. Here we report a 33-year-old woman who underwent LTPL approximately four years after severe HD-associated lung injury. The patient was initially admitted to the intensive care unit and was supported by a high-flow nasal cannula. Although she had been discharged, she was recurrently admitted to our hospital due to progressive lung fibrosis and a persistent decline in lung function. Finally, sequential double LTPL was successfully performed, and the patient``s clinical and radiological findings showed significant improvement. Therefore, we conclude that LTPL can be a therapeutic option for patients with chronic inhalation injury.
2011年春季,韩国报道了一起因使用加湿器消毒剂(HD)导致的肺部损伤的聚集性病例。许多患者需要机械通气,体外膜氧合,甚至肺移植(LTPL)。然而,hd相关肺损伤的长期病程尚不清楚,因为大多数幸存者恢复了正常的肺功能。在这里,我们报告了一位33岁的女性,她在严重的hd相关肺损伤大约四年后接受了LTPL。患者最初住进重症监护室,并由高流量鼻插管支持。虽然她已经出院,但由于进行性肺纤维化和肺功能持续下降,她反复住进我院。最后,连续双LTPL成功实施,患者的临床和放射学表现明显改善。因此,我们认为LTPL可以作为慢性吸入性损伤患者的治疗选择。

Therefore, we conclude that LTPL can be a therapeutic option for patients with chronic inhalation injury.","PeriodicalId":255255,"journal":{"name":"The Korean Journal of Critical Care Medicine","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115833371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A patient had undergone left pneumonectomy for lung cancer and had an increased risk of fatal complications such as pneumonia, including acute respiratory distress syndrome (ARDS). The treatment effects of veno-venous extracorporeal membrane oxygenation (VV-ECMO) for ARDS of postpneumonectomy patient are uncertain. A 74-year-old man with one lung experienced aspiration pneumonia while swallowing pills after the operation, and his condition progressed to ARDS within a day. He was successfully treated with VV-ECMO support and intensive care unit care.

For trauma patients with severe shock, massive fluid resuscitation is necessary. However, shock and a large amount of fluid can cause bowel and retroperitoneal edema, which sometimes leads to abdominal compartment syndrome in patients without abdomino-pelvic injury. If other emergent operations except intraabdomen are needed, a distended abdomen is likely to be recognized late, leading to multiple organ dysfunction. Herein, we report two cases of a 23-year-old woman who was in a car accident and a 53-year old man who was pressed on his leg by a pressing machine; severe brain swelling and popliteal vessel injury were diagnosed, respectively. They were both in severe shock and massive fluid resuscitation was required in the emergency department. Distended abdomen was recognized in both the female and male patients immediately after neurosurgical operation and immediately before orthopaedic operation in the operating room, respectively. Decompressive laparotomy revealed massive ascites with retroperitoneal edema.
对于严重休克的创伤患者,大量液体复苏是必要的。然而,休克和大量液体可引起肠道和腹膜后水肿,这有时会导致无腹盆腔损伤的患者出现腹膜间室综合征。如果需要除腹内手术外的其他紧急手术,腹胀很可能被发现较晚,导致多器官功能障碍。在此,我们报告了两例23岁的女性车祸和53岁的男性被压在他的腿上的压机;分别诊断为严重脑肿胀和腘血管损伤。他们都受到了严重的休克,需要在急诊室进行大量的液体复苏。女性和男性患者分别在神经外科手术后立即和骨科手术前在手术室发现腹胀。剖腹减压术发现大量腹水伴腹膜后水肿。

Recent Trend in Therapeutic Hypothermia and Early-Onset Pneumonia in Cardiac Arrest 心脏骤停患者治疗性低温和早发性肺炎的最新趋势

The ultimate goal of cardiopulmonary resuscitation (CPR) is restoring spontaneous circulation and minimizing neurologic deficits. Since two human studies presented improved neurologic outcome and reduced mortality after cardiac arrest in 2002,[1,2] therapeutic hypothermia (TH) has been recommended consistently in the international CPR guidelines for post-cardiac arrest care.[3-5] TH improves the neurologic outcome due to attenuation of the inflammatory response in the brain.[1] On the other hand, TH can have systemic adverse effect such as high infection rate. Geurts et al.[6] emphasized in a meta-analysis of 23 studies that TH was a risk factor of both pneumonia and sepsis after return of spontaneous circulation in cardiac arrest patients. Even if TH is not used, infection is more common in post-cardiac arrest care,[7] and pneumonia is the most common type of infection in out-of-hospital cardiac arrest (OHCA).[8] The cause of this high incidence of pneumonia in OHCA is that factors such as loss of airway protection, changed mental status, pulmonary contusion by chest compression, emergent airway access, and mechanical ventilation increase the risk of pulmonary infection.[7] Some studies have suggested that post-resuscitation pneumonia could be divided into early-onset and late-onset pneumonia according to onset time and prevalent pathogens; however, the onset time varied from three to seven days depending on the study.[8-11] Perbet et al.[11] reported that TH was an independent risk factor of early-onset pneumonia (EOP), which prolonged mechanical ventilation support and intensive care unit (ICU) stay with unchanged neurologic outcome and ICU mortality in a retrospective and large (641 patients) cohort study. Therefore, intensivists should be aware of management of EOP while conducting HT. Prophylactic antibiotics decreased the incidence of EOP in comatose patients with a variety of causes such as head trauma, intracranial hemorrhage, stroke, or cardiac arrest.[12] In a recently published study, prophylactic antibiotics reduced the incidence of pneumonia in cardiac arrest survivors undergoing TH, but they did not reduce patient mortality.[13] However, the researchers did not distinguish earlyor late-onset pneumonia. Kim et al.[14] have reported that prophylactic antibiotics in OHCA patients undergoing TH does not reduce the incidence of EOP. The authors insisted that the study evaluated the effect of prophylactic antibiotics on EOP for the first time. The incidence of EOP was 29.2% and 30.0% in prophylactic antibiotics and non-antibiotics, respec-
心肺复苏术(CPR)的最终目标是恢复自然循环和减少神经功能缺陷。自2002年两项人体研究显示心脏骤停后神经系统预后改善和死亡率降低以来[1,2],治疗性低温(TH)已被国际心肺复苏指南一致推荐用于心脏骤停后的护理。[3-5] TH通过减弱脑内炎症反应改善神经系统预后[1]。另一方面,TH可产生全身不良反应,如高感染率。Geurts等[6]在对23项研究的荟萃分析中强调,TH是心脏骤停患者自发循环恢复后肺炎和败血症的危险因素。即使不使用TH,感染在心脏骤停后护理中也更为常见[7],肺炎是院外心脏骤停(OHCA)中最常见的感染类型[8]。OHCA中肺炎高发的原因是气道保护丧失、精神状态改变、胸部压迫引起的肺挫伤、紧急气道通路和机械通气等因素增加了肺部感染的风险。[7]有研究认为,复苏后肺炎根据发病时间和流行病原体可分为早发性和晚发性肺炎;然而,根据不同的研究,发病时间从3天到7天不等。[8-11] Perbet等[11]在一项回顾性大型(641例)队列研究中报道TH是早发性肺炎(EOP)的独立危险因素,延长了机械通气支持和重症监护病房(ICU)的住院时间,神经系统预后和ICU死亡率不变。因此,强化医师在进行HT时应注意EOP的管理。预防性抗生素可降低因头部创伤、颅内出血、中风或心脏骤停等多种原因导致的昏迷患者EOP的发生率。[12]在最近发表的一项研究中,预防性抗生素降低了接受TH的心脏骤停幸存者的肺炎发病率,但并没有降低患者的死亡率。[13]然而,研究人员没有区分早发性肺炎和晚发性肺炎。Kim等人[14]报道,接受TH的OHCA患者预防性使用抗生素并不能降低EOP的发生率。作者认为,本研究首次评价了预防性抗生素对EOP的影响。预防性抗生素和非抗生素组EOP发生率分别为29.2%和30.0%
