Veno-venous extracorporeal membrane oxygenation (VV ECMO) has become an important support modality for patients with acute respiratory failure refractory to optimal medical therapy, such as low tidal volume mechanical ventilator support, early paralytic infusion, and early prone positioning. The objective of this cohort study was to investigate the causes and timing of in-hospital mortality in patients on VV ECMO. All patients, excluding trauma and bridge to lung transplant, admitted 8/2014–6/2019 to a specialty ICU for VV ECMO were reviewed. Two hundred twenty-five patients were included. In-hospital mortality was 24.4% ( n = 55). Most non-survivors (46/55, 84%) died prior to lung recovery and decannulation from VV ECMO. Most common cause of death (COD) for patients who died on VV ECMO was removal of life sustaining therapy (LST) in setting of multisystem organ failure (MSOF) ( n = 24). Nine patients died a median of 9 days [6, 11] after decannulation. Most common COD in these patients was palliative withdrawal of LST due to poor prognosis ( n = 3). Non-survivors were older and had worse predictive mortality scores than survivors. We found that death in patients supported with VV ECMO in our study most often occurs prior to decannulation and lung recovery. This study demonstrated that the most common cause of death in patients supported with VV ECMO was removal of LST due MSOF. Acute hemorrhage (systemic or intracranial) was not found to be a common cause of death in our patient population.

Abstract Background Systemic rheumatic diseases (SRDs) are a group of inflammatory disorders that can require intensive care unit (ICU) admission because of multiorgan involvement with end-organ failure(s). Critically ill SRD patients requiring extracorporeal membrane oxygenation (ECMO) were studied to gain insight into their characteristics and outcomes. Methods This French monocenter, retrospective study included all SRD patients requiring venovenous (VV)- or venoarterial (VA)-ECMO admitted to a 26-bed ECMO-dedicated ICU from January 2006 to February 2020. The primary endpoint was in-hospital mortality. Results Ninety patients (male/female ratio: 0.5; mean age at admission: 41.6 ± 15.2 years) admitted to the ICU received VA/VV-ECMO, respectively, for an SRD-related flare (n = 69, n = 38/31) or infection (n = 21, n = 10/11). SRD was diagnosed in-ICU for 31 (34.4%) patients. In-ICU and in-hospital mortality rates were 48.9 and 51.1%, respectively. Nine patients were bridged to cardiac (n = 5) or lung transplantation (n = 4), or left ventricular assist device (n = 2). The Cox multivariable model retained the following independent predictors of in-hospital mortality: in-ICU SRD diagnosis, day-0 Simplified Acute Physiology Score (SAPS) II score ≥ 70 and arterial lactate ≥ 7.5 mmol/L for VA-ECMO–treated patients; diagnosis other than vasculitis, day-0 SAPS II score ≥ 70, ventilator-associated pneumonia and arterial lactate ≥ 7.5 mmol/L for VV-ECMO–treated patients. Conclusions ECMO support is a relevant rescue technique for critically ill SRD patients, with 49% survival at hospital discharge. Vasculitis was independently associated with favorable outcomes of VV-ECMO–treated patients. Further studies are needed to specify the role of ECMO for SRD patients.

Objective We aimed to examine the risk factors and prognosis of nosocomial pneumonia (NP) during extracorporeal membrane oxygenation (ECMO). Methods We retrospectively analyzed data of patients who received ECMO at the Affiliated Hangzhou Hospital of Nanjing Medical University between January 2013 and August 2019. The primary outcome was the survival-to-discharge rate. Results Sixty-nine patients who received ECMO were enrolled, median age 42 years and 26 (37.7%) women; 14 (20.3%) patients developed NP. The NP incidence was 24.7/1000 ECMO days. Patients with NP had a higher proportion receiving veno-venous (VV) ECMO (50% vs. 7.3%); longer ECMO support duration (276 vs. 140 hours), longer ventilator support duration before ECMO weaning (14.5 vs. 6 days), lower ECMO weaning success rate (50.0% vs. 81.8%), and lower survival-to-discharge rate (28.6% vs. 72.7%) than patients without NP. Multivariable analysis showed independent risk factors that predicted NP during ECMO were ventilator support duration before ECMO weaning (odds ratio [OR] = 1.288; 95% confidence interval [CI]: 1.111–1.494) and VV ECMO mode (OR = 10.970; 95% CI: 1.758–68.467). Conclusion NP during ECMO was associated with ventilator support duration before ECMO weaning and VV ECMO mode. Clinicians should shorten the respiratory support duration for patients undergoing ECMO to prevent NP.

Bleomycin treats malignancies, such as germ cell tumours and Hodgkin lymphoma. While efficacious, it can cause severe drug-induced lung injury. We present a 42-year-old patient with stage IIB seminoma treated with radical orchiectomy followed by adjuvant chemotherapy with bleomycin, etoposide and cisplatin. His postbleomycin course was complicated by the rapid onset of hypoxic respiratory failure, progressing to acute respiratory distress syndrome and requiring venovenous extracorporeal membrane oxygenation (VV-ECMO) support. Although the patient was treated with high dose systemic steroids and ultra-protective ventilator strategies to minimise ventilator-induced lung injury while on VV-ECMO, his lung injury failed to improve. Care was withdrawn 29 days later. Lung autopsy revealed diffuse organising pneumonia. We found six case reports (including this one) of bleomycin-induced lung injury requiring VV-ECMO with a cumulative survival of 33% (2/6). While VV-ECMO may be used to bridge patients to recovery or lung transplant, the mortality is high.

Introduction: Different cannulation approaches existed for veno-venous extracorporeal membrane oxygenation (VV ECMO). We aimed to compare the atrio-femoral (AF) and femoro-atrial (FA) configuration in terms of their flow efficiency and influence on patient outcome. Method: This was a single-centre, retrospective case control study. Adult patients admitted to the Intensive Care Unit and required VV ECMO service at Tuen Mun Hospital, Hong Kong, from June 2015 to January 2020 were included. Data were collected from our ECMO database for comparison. Results: Between June 2015 and January 2020, eight patients received AF configuration and 19 patients received FA configuration. The maximum achieved flow in the AF group was significantly higher than that in the FA group (4.08 ± 0.57 L/min vs. 3.52 ± 0.58 L/min, p = 0.03). The fluid balance in first 3 days of ECMO was significantly lower in the AF group compared to that in the FA group (1.16 ± 2.71 L vs. 3.46 ± 1.97 L, p = 0.02). As well, the chance for successful awake ECMO was statistically higher in the AF group (p = 0.048). Conclusion: Atrio-femoral configuration in VV ECMO was associated with a higher maximum achieved ECMO flow, less fluid gain in first 3 days of ECMO and more successful awake ECMO.

Introduction: The purpose of this study is to describe sedation and analgesia management, and identify the factors associated with increased demand for medication in acute respiratory distress syndrome (ARDS) patients receiving venovenous extracorporeal membrane oxygenation (VV-ECMO). Methods: This retrospective, single-center study included consecutive adult ARDS patients who received VV-ECMO for at least 24 hours from January 2018 to December 2020 in a comprehensive intensive care unit. The electronic medical records were retrospectively reviewed to collect data. Results: Forty-two adult patients meeting the inclusion criteria were included in the study. Midazolam, sufentanil, and remifentanil were main sedatives and analgesics used in the patient population. The morphine equivalents, representative of the demand for opioids, was 512.9 (IQR, 294.5, 798.2) mg/day. The midazolam equivalents, representative of benzodiazepine requirement, was 279.6 (IQR, 208.8, 384.5) mg/day. The levels of serum creatinine, total bilirubin, lactic acid, SOFA score, and APACHE Ⅱ score at cannulation were found to be associated with opiate or benzodiazepine requirements. Multiple linear regression analysis revealed a linear correlation between midazolam equivalents and morphine equivalents (p < 0.001). In addition, there was a negative linear correlation between Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score and midazolam equivalents (p = 0.024). Conclusions: The sedation and analgesia requirements of ARDS patients receiving VV-ECMO often increase simultaneously. More large-scale studies are needed to confirm the risk factors for increased sedation and analgesia needs in patients supported on VV-ECMO.

The mortality rate for respiratory failure resulting from obesity hypoventilation syndrome is high if it requires ventilator management. We describe a case of severe acute respiratory failure resulting from obesity hypoventilation syndrome (BMI, 60.2 kg/m2) successfully treated with venovenous extracorporeal membrane oxygenation (VV-ECMO). During ECMO management, a mucus plug was removed by bronchoscopy daily and 18 L of water was removed using diuretics, resulting in weight loss of 24 kg. The patient was weaned from ECMO on day 5, extubated on day 16, and discharged on day 21. The fundamental treatment for obesity hypoventilation syndrome in morbidly obese patients is weight loss. VV-ECMO can be used for respiratory support until weight loss has been achieved.

Venovenous extracorporeal membrane oxygenation (vv-ECMO) is a highly invasive method for organ support that is gaining in popularity due to recent technical advances and its successful application in the recent H1N1 epidemic. Although running a vv-ECMO program is potentially feasible for many hospitals, there are many theoretical concepts and practical issues that merit attention and require expertise. In this review, we focus on indications for vv-ECMO, components of the circuit, and management of patients on vv-ECMO. Concepts regarding oxygenation and decarboxylation and how they can be influenced are discussed. Day-to-day management, weaning, and most frequent complications are covered in light of the recent literature.

Introduction. Some degree of recirculation occurs during venovenous extracorporeal membrane oxygenation (VV ECMO) which, (1) reduces oxygen (O2) delivery, and (2) renders venous line oxygen saturation monitoring unreliable as an index of perfusion adequacy. Ultrasound dilution allows clinicians to rapidly monitor and quantify the percent of recirculation that is occurring during VV ECMO. The purpose of this paper is to test whether accurate patient mixed venous oxygen saturation (SVO2) can be calculated once recirculation is determined. It is hypothesized that it is possible to derive patient mixed venous saturations by integrating recirculation data with the ECMO circuit arterial and venous line oxygen saturation data. Methods. A test system containing sheep blood adjusted to three venous saturations (low-30%, med-60%, high-80%) was interfaced via a mixing chamber with a standard VV ECMO circuit. Recirculation, arterial line and venous line oxygen saturations were measured and entered into a derived equation to calculate the mixed venous saturation. The resulting value was compared to the actual mixed venous saturation. Results. Recirculation was held constant at 30.5 ± 2.0% for all tests. A linear regression comparison of “actual” versus “calculated” mixed venous saturations produced a correlation coefficient of R2 = 0.88. Direct comparison of actual versus calculated saturations for all three test groups respectively are as follows; Low: 31.8 ± 3.95% vs. 37.0 ± 6.7% (NS), Med: 61.7 ± 1.5% vs. 72.3 ± 1.8% (p < 0.05), High: 84.4 ± 0.9% vs. 91.2 ± 1.1% (p < 0.05). Discussion. There was a strong correlation between actual and calculated mixed venous saturations; however, significant differences between actual and calculated values where observed at the Med and High groups. While this data suggests that using quantified recirculation data to calculate SVO2 is promising, it appears that a straightforward derivative of the oxygen saturation-based equation may not be sufficient to produce clinically accurate calculations of actual mixed venous saturations.

Objective: To describe clinically pertinent challenges of managing sedation in COVID-19 patients on venovenous extracorporeal membrane oxygenation (VV-ECMO) and describe considerations for enhanced safety and efficacy of pharmacological agents used. Data Sources: A PubMed search was performed using the following search terms: ECMO, ARDS, sedation, COVID-19, coronavirus, opioids, analgesia, fentanyl, hydromorphone, morphine, oxycodone, methadone, ketamine, propofol, dexmedetomidine, clonidine, benzodiazepines, midazolam, lorazepam, and diazepam. Study Selection and Data Extraction: Relevant clinical and pharmacokinetic studies were considered. All studies included were published between January 1988 and March 2021. Data Synthesis: Patients with acute respiratory distress syndrome secondary to COVID-19 may progress to requiring VV-ECMO support. Agents frequently used for sedation and analgesia in these patients have been shown to have significant adsorption to ECMO circuitry, leading to possible diminished clinical efficacy. Use of hydromorphone-based analgesia has been associated with improved clinical outcomes in patients on VV-ECMO. However, safety and efficacy regarding use of other agents in this patient population remains an area of further research. Relevance to Patient Care and Clinical Practice: This review addresses clinical challenges associated with sedation management in COVID-19 patients requiring VV-ECMO support and provides potential strategies to overcome these challenges. Conclusions: Historically, sedation and analgesia management in patients requiring ECMO support have posed a challenge for bedside clinicians given the unique physiological and pharmacokinetic changes in this patient population. A multimodal strategy to managing analgesia and sedation should be used, and the use of enteral agents may play a role in reducing parenteral agent requirements.
