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.

Background: Acute mesenteric ischaemia is a severe complication in critically ill patients, but has never been evaluated in patients on veno-arterial extracorporeal membrane oxygenation (V-A ECMO). This study was designed to determine the prevalence of mesenteric ischaemia in patients supported by V-A ECMO and to evaluate its risk factors, as well as to appreciate therapeutic modalities and outcome. Methods: In a retrospective single centre study (January 2013 to January 2017), all consecutive adult patients who underwent V-A ECMO were included, with exclusion of those dying in the first 24 hours. Diagnosis of mesenteric ischaemia was performed using digestive endoscopy, computed tomography scan or first-line laparotomy. Results: One hundred and fifty V-A ECMOs were implanted (65 for post-cardiotomy shock, 85 for acute cardiogenic shock, including 39 patients after refractory cardiac arrest). Overall, median age was 58 (48–69) years and mortality 56%. Acute mesenteric ischaemia was suspected in 38 patients, with a delay of four (2–7) days after ECMO implantation, and confirmed in 14 patients, that is, a prevalence of 9%. Exploratory laparotomy was performed in six out of 14 patients, the others being too unstable to undergo surgery. All patients with mesenteric ischaemia died. Independent risk factors for developing mesenteric ischaemia were renal replacement therapy (odds ratio (OR) 4.5, 95% confidence interval (CI) 1.3–15.7, p=0.02) and onset of a second shock within the first five days (OR 7.8, 95% CI 1.5–41.3, p=0.02). Conversely, early initiation of enteral nutrition was negatively associated with mesenteric ischaemia (OR 0.15, 95% CI 0.03–0.69, p=0.02). Conclusions: Acute mesenteric ischaemia is a relatively frequent but dramatic complication among patients on V-A ECMO.

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 Among various complications of extracorporeal membrane oxygenation (ECMO), stroke continues to be a major factor that worsens the clinical outcome because it is associated with mortality and adverse neurologic outcomes. Appropriate risk evaluation, screening, and management of neurologic injury under ECMO support has not yet been established and requires further investigation. Thus, this study analyzes the stroke related risk factors and outcomes in order to determine the appropriate intervention to minimize neurologic sequalae while on ECMO. Method Total 1039 patients who underwent ECMO from January 2012 to September 2019 at the Samsung Medical Center were reviewed and 759 subjects were selected for the analysis. The exclusion criteria were age < 18y, failure of successful ECMO initiation, multiple ECMO runs, underlying severe brain injury, and incomplete medical records. Multivariate analysis was performed to identify the risk factors of strokes on ECMO support using cox proportional hazard regression. In order to analyze the timing of stroke after ECMO initiation, the Mann–Whitney U test and Kruskal–Wallis rank sum test were performed.Results Among The overall incidence of stroke was 5.1% (n = 39) without a significant difference between venoarterial (VA) and venovenous(VV) ECMO (5.3% and 4.8%, respectively, p = 0.480). Independent risk factors for stroke were intraaortic balloon pump (IABP, p = 0.0008) and a history of stroke (p = 0.0354). Most hypoxic brain injuries were found in the VA ECMO (93.3%), and 54.5% of intracranial hemorrhage were in the VV ECMO. Most patients with strokes (61.5%) were diagnosed within 72hours after ECMO initiation. The time taken for stroke event from the time of ECMO insertion was shorter in the VA ECMO than in the VV ECMO (median 1.5 vs. 3 days). The stroke group had a higher mortality rate than the non-stroke group (64.1% and 44.7%, respectively, p = 0.014). Conclusion Concurrent ECMO and IABP use may increase the incidence of stroke during ECMO support. Evaluation for stroke that includes CT within 72 hours of ECMO insertion may enable early diagnosis, allowing timely intervention.

Background Congenital heart disease (CHD) is the most common neonatal and pediatric cardiac indication for extracorporeal membrane oxygenation (ECMO). Risk factors of survival and neurologic complication were different in many centers. We sought to evaluate survival and neurological outcome after ECMO in patients with CHD. Methods We retrospectively reviewed the medical records of 37 patients (<16 years old) who received ECMO. Indications for ECMO were failure to wean from cardiopulmonary bypass in 18 patients, extracorporeal cardiopulmonary resuscitation (ECPR) in 13 patients, and others in 6 patients. The median cardiopulmonary resuscitation (CPR) duration in ECPR patients was 48 min (interquartile range: 38–53 min). Neurological outcomes were evaluated using the Pediatric Cerebral Performance Category (PCPC) scale one year after hospital discharge. Results The median ECMO duration was 160 (91–286) h. Twenty-nine patients (78%) were successfully weaned off ECMO. Overall survival to hospital discharge was 59%. Risk factors of mortality were as follows: ECMO duration >1 week and urine output <1 mL/kg/h in the first 24 h after ECMO induction by multivariable analysis. Of the 22 survivors, 15 (68%) patients had a favorable outcome (PCPC ≤2). Risk factors for unfavorable outcomes (PCPC ≥3) included ECPR as indication and CPR of longer than 40 min. Conclusions Longer ECMO duration and lower urine output were associated with increased mortality. Neurologic outcomes were not satisfactory when CPR was required for a longer period before ECMO establishment.

Background: Agitation and delirium in critically ill patients after cardiac surgery carry poor in-hospital prognosis. Identifying risk factors may promote its prevention and management. Accordingly, this study aimed to evaluate the incidence of agitation and hyperactive delirium in postcardiotomy patients during the extracorporeal membrane oxygenation support and to identify the risk factors for its development. Methods: This single center, retrospective study was conducted at Beijing Anzhen Hospital, Capital Medical University. Data were extracted from the prospective institutional registry database of extracorporeal membrane oxygenation patients. Univariate and multivariate logistic regression analyses were performed to predict risk factors. Results: A total of 170 consecutive adult patients underwent extracorporeal membrane oxygenation in our hospital from January 2016 to December 2017. Ninety-four patients were included in the final analysis. The incidence of agitation and hyperactive delirium was 35% in our population of extracorporeal membrane oxygenation–supported postcardiotomy patients. Agitation and delirium usually occurred within the first 3 days of extracorporeal membrane oxygenation. Multivariable analysis showed that history of previous stroke (without preoperative cognitive dysfunction; odds ratio, 4.425, 95% confidence interval: 1.171-16.716; p = 0.028) and mean arterial pressure reduction (before extracorporeal membrane oxygenation initiation) ⩾ 49 mmHg (odds ratio, 7.570, 95% confidence interval: 2.366-24.219, p = 0.001) were independent risk factors for agitation and hyperactive delirium during extracorporeal membrane oxygenation support. The areas under the receiver operating characteristic curve for the prediction of agitation and hyperactive delirium was 0.704 (95% confidence interval 0.589-0.820, p = 0.001). There was more severe arrhythmia in the agitation patients. Conclusion: Our results suggest that the prevalence of agitation and hyperactive delirium in postcardiotomy patients with extracorporeal membrane oxygenation support is high. In addition, previous stroke and severe mean arterial pressure reduction before extracorporeal membrane oxygenation initiation is predictive of agitation and hyperactive delirium.

<b><i>Background:</i></b> Thromboembolic events (TEEs) may significantly complicate the clinical management of patients with testicular germ cell tumours (GCTs). We analysed a cohort of GCT patients for the occurrence of TEEs and looked to possible pathogenetic factors. <b><i>Patients, Methods:</i></b> TEEs occurring within 6 months after diagnosis were retrospectively analysed in 317 consecutive patients with testicular GCT (median age 37 years, 198 seminoma, 119 nonseminoma). The following factors were analysed for association with TEE: histology, age, clinical stage (CS), chemotherapy, use of a central venous access device (CVA). Data analysis involved descriptive statistical methods with multivariable analysis to identify independent risk factors. <b><i>Results:</i></b> Twenty-three TEEs (7.3%) were observed, 18 deep vein thromboses, 4 pulmonary embolisms, and 1 myocardial infarction. Univariable risk calculation yielded the following odds ratios (ORs) : &#x3e;CS1 OR = 43.7 (95% confidence intervals [CIs] 9.9–191.6); chemotherapy OR = 7.8 (95% CI 2.3–26.6); CVA OR = 30.5 (95% CI 11.0–84.3). Multivariable analysis identified only CS &#x3e; 1 (OR = 16.9; 95% CI 3.5–82.4) and CVA (OR = 9.0; 95% CI 2.9–27.5) as independent risk factors. <b><i>Conclusions:</i></b> Patients with CSs &#x3e;CS1 are at significantly increased risk of TEEs even without chemotherapy. Particular high risk is associated with the use of CVA devices for chemotherapy. Caregivers of GCT patients must be aware of the particular risk of TEEs.

Abstract Introduction Whilst most patients during the COVID pandemic made an uneventful recovery,there was a significant minority in whom the disease was severe and unfortunately fatal. This survey aims to examine and evaluate risk factors for those patients who died of COVID and to identify any markers for improvement in the management of such patients during future COVID surges. Methods Medical records of all patients who died within a multi-ethnic, inner city acute district general hospital over a 6-week period in 2020 were examined. Data collected included demographic details, medical comorbidities, and type of ward where they received care. Multivariable analysis using stepwise backward logistic regression was conducted to examine independent risk factors for these patients. Results Of 275 deaths,204 were related to COVID. Compared to non-COVID deaths(n = 71), there were no age differences. There were significantly more deaths in males (58%vs39%,P &lt; 0.001)) and in Black African and South Asian groups. 18% of COVID deaths were those who were not frail (Frailty Rockwood Scale 1–3) whereas there were no non-COVID deaths in this group(P &lt; 0.001). 69% of COVID deaths occurred in general medical wards whereas 19% in critical care units (90% and 7% for non-COVID deaths,p &lt; 0.001). COVID patients died more quickly compared to non-COVID patients (length of stay mean, 11vs21,p &lt; 0.001). Medical factors prevalent in &gt;20% of COVID deaths included Diabetes, Hypertension, Chronic Heart Disease, Chronic Kidney Disease,and Dementia. Multivariable analyses showed males (OR 1.9), age &gt; 70(OR 2.0), frailty (OR 2.3) were independent risk factors for COVID deaths. Discussion Compared to non-COVID deaths,COVID deaths were more common in previously well individuals,males,Black African and South Asian ethnicity, but multivariable analyses showed males, age &gt; 70 and frailty were independent risk factors for COVID deaths. This survey indicates that greater psychological support may be required for healthcare workers on general medical wards who looked after greater proportion of COVID deaths.

Objectives.To analyze infectious complications that occur in patients who receive extracorporeal membrane oxygenation (ECMO), associated risk factors, and consequences on patient outcome.Design.Retrospective observational survey from 2005 through 2011.Participants and Setting.Patients who required ECMO in an Australian referral center.Methods.Cases of bloodstream infection (BSI), catheter-associated urinary tract infection (CAUTI), and ventilator-associated pneumonia (YAP) that occurred in patients who received ECMO were analyzed.Results.A total of 146 ECMO procedures were performed for more than 48 hours in 139 patients, and 36 patients had a total of 46 infections (30.1 infectious episodes per 1,000 days of ECMO). They included 24 cases of BSI, 6 of them secondary to VAP; 23 cases of VAP; and 5 cases of CAUTI. The most frequent pathogens were Enterobacteriaceae (found in 16 of 46 cases), and Candida was the most common cause of BSI (in 9 of 24 cases). The Sequential Organ Failure Assessment score before ECMO initiation and the number of days of support were independenuy associated with a risk of BSI, with odds ratios of 1.23 (95% confidence interval [CI], 1.03-1.47; P = .019) and 1.08(95% CI, 1.03-1.19]; P = .006), respectively. Infected patients did not have a significantly higher mortality compared with uninfected patients (41.7% vs 32%; P = .315), but intensive care unit length of stay (16 days [interquartile range, 8-26 days] vs 11 days [IQR, 4-19 days]; P = .012) and hospital length of stay (33.5 days [interquartile range, 15.5-55.5] vs 24 days [interquartile range, 9-42 days]; P = .029) were longer.Conclusion.The probability of infection increased with the duration of support and the severity of illness before initiation of ECMO. Infections affected length of stay but did not have an impact on mortality.

The objective of this study was to determine if propofol administration to veno-venous (VV) extracorporeal membrane oxygenation (ECMO) patients was associated with more incidents of oxygenator failure when compared to patients who did not receive propofol. This was a single center, retrospective cohort study. The primary outcome of the study is oxygenator exchanges per ECMO day in patients who received propofol versus those who did not receive propofol. Patients were 18 years or older on VV-ECMO support between January 1, 2015 and January 31, 2018. Patients were excluded if they required ECMO support for less than 48 h or greater than 21 days. There were five patients in the propofol arm that required oxygenator exchanges and seven patients in the control arm. The total number of oxygenator exchanges per ECMO day was not significantly different between groups ( p = 0.50). When comparing those who required an oxygenator exchange and those who did not, there was no difference in the cumulative dose of propofol received per ECMO hour (0.64 mg/kg/h vs 0.96 mg/kg/h; p = 0.16). Propofol use in patients on VV-ECMO does not appear to increase the number of oxygenator exchanges.

AbstractAlthough extracorporeal membrane oxygenation (ECMO) is increasingly utilized, only a limited level of experience has been reported in postpartum cardiopulmonary failure. Ten critically ill postpartum patients who received ECMO were included between January 2010 and December 2018 in this retrospective observational study. The main indication for ECMO support was peripartum cardiomyopathy (n = 5), followed by postpartum hemorrhage (n = 2). Nine patients initially received veno-arterial ECMO, and one patient received veno-venous ECMO. Major bleeding occurred in six patients. The median number of units of red blood cells (RBC) transfused during ECMO was 14.5 units (interquartile range 6.8–37.8 units), and most RBC transfusions occurred on the first day of ECMO. The survival-to-discharge rate was 80%. Compared to the survival outcomes in female patients of similar age who received ECMO, the survival outcomes were significantly better in the study population (56% versus 80%, P = 0.0004). Despite the high risk of major bleeding, ECMO for patients with postpartum cardiac or respiratory failure showed excellent survival outcomes. ECMO is feasible in these patients and can be carried out with good outcomes in an experienced centre.
