Background: Antithrombin III deficiency can occur with heparin anticoagulation during extracorporeal membrane oxygenation leading to heparin resistance. Antithrombin III supplementation has been shown to improve anticoagulation; however, there is no consensus on appropriate administration. We described the effect of antithrombin III supplementation on coagulation parameters in adult and pediatric extracorporeal membrane oxygenation patients. Methods: We conducted a retrospective cohort study using electronic medical records of patients who received ⩾1 dose of antithrombin III during extracorporeal membrane oxygenation while on continuous heparin. Endpoints included the change in anti-Xa levels and antithrombin III activity at −6 versus 6 h relative to antithrombin III supplementation, and heparin infusion rates at 6 versus 12 h after antithrombin III supplementation. Results: Eighteen patients receiving 36 antithrombin III administrations were analyzed. Mean (standard deviation) anti-Xa values at −6 versus 6 h were 0.15 (0.07) versus 0.24 (0.15) IU/mL ( p-value: 0.250) for pediatrics and 0.19 (0.22) versus 0.31 (0.27) IU/mL ( p-value: 0.052) for adults. Mean (standard deviation) plasma antithrombin III activity at the same intervals were 32% (14.2%) versus 66.8% (25.1%; p-value: 0.062) for pediatrics and 30.3% (14%) versus 52.8% (8.1%; p-value: 0.094) for adults. Mean (standard deviation) heparin rates at 6 versus 12 h after antithrombin III for pediatrics were 23.6 (6) versus 23.5 (6.5) units/kg/h ( p-value: 0.728), and 15.3 (6.6) versus 13.5 (8) units/kg/h ( p-value: 0.188) for adults. Conclusion: Administration of antithrombin III improved anti-Xa levels in both populations, however, did not significantly reduce heparin rates. Our findings suggest that the use of antithrombin III restores heparin responsiveness in patients with low antithrombin III activity and low anti-Xa activity.

Purpose: The purpose of this study was to evaluate the cost effectiveness of argatroban compared to heparin during extracorporeal membrane oxygenation (ECMO) therapy. Methods: This was a retrospective study of patients who received argatroban or heparin infusions with ECMO therapy at a community hospital between January 1, 2017 and June 30, 2018. Adult patients who received heparin or argatroban for at least 48 hours while on venovenous (VV) or venoarterial (VA) ECMO were included. Patients with temporary mechanical circulatory assist devices were excluded. Each continuous course of anticoagulant exposure that met the inclusion criteria was evaluated. The primary endpoint was the total cost of anticoagulant therapy for heparin versus argatroban, including all administered study drugs, blood or factor products, and associated laboratory tests. Secondary endpoints included safety and efficacy of anticoagulation with each agent during ECMO. Documentation of bleeding events, circuit clotting, and ischemic events were noted. Partial thromboplastin time (PTT) values were evaluated for time to therapeutic range and percentage of therapeutic PTTs. Results: A total of 11 courses of argatroban and 24 courses of heparin anticoagulation were included in the study. The average cost per course of argatroban was less than the average cost per course of heparin ($7,091.98 vs $15,323.49, respectively; P value = 0.15). Furthermore, argatroban was not associated with an increased incidence of bleeding, thrombotic, or ischemic events. Conclusion: Argatroban may be more cost-effective during ECMO therapy in patients with low antithrombin III levels without increased risk of adverse events.

Purpose Achieving effective anticoagulation during neonatal extracorporeal membrane oxygenation (ECMO) without increasing the risk of hemorrhage remains challenging. The use of antithrombin III (AT-III) for this purpose has been examined, but studies have been limited to intermittent bolus dosing. We aimed to evaluate the efficacy and safety of an institutionally developed AT-III continuous infusion protocol in neonates receiving ECMO for the treatment of congenital diaphragmatic hernia (CDH). Methods In this single center, retrospective study, all neonates with a CDH who received ECMO support during the study period were included. Data on anticoagulation labs and therapy, life-threatening bleeding, and circuit changes were analyzed. Results Eleven patients were divided into two groups: patients with AT-III continuous infusion ( n = 5) and without ( n = 6). There were no differences in the gestational age ( p = 0.29), sex ( p = 1.00), ECMO duration ( p = 0.59), or initial AT-III levels ( p = 0.76) between groups. Patients in the AT-III infusion group had on average 18.5% higher AT-III levels ( p < 0.0001). Patients receiving continuous AT-III infusions spent a significantly higher percentage of ECMO time within the therapeutic range, measured using anti-Factor Xa levels (64.9±4.2% vs. 29.1±8.57%, p = 0.008), and required fewer changes to the heparin infusion rate (6.48±0.88 vs 2.38±0.36 changes/day changes/day, p = 0.005). Multivariate analysis revealed continuous infusion of AT-III did not increase the rate of intracranial or surgical bleeding ( p = 0.27). Conclusion AT-III as a continuous infusion in CDH neonates on ECMO provides a decreased need to modify heparin infusion and more consistent therapeutic anticoagulation without increasing the risk of life-threatening bleeding.

SummaryAntithrombin-III activity was determined in 752 patients with a history of venous thrombosis and/or pulmonary embolism. 54 patients (7.18%) had an antithrombin-III activity below the normal range. Among these were 13 patients (1.73%) with proven hereditary deficiency. 14 patients were judged to have probable hereditary antithrombin-III deficiency, because they had a positive family history, but antithrombin-III deficiency could not be verified in other members of the family. In the 27 remaining patients (most of them with only slight deficiency) hereditary antithrombin-III deficiency was unlikely. The prevalence of hereditary antithrombin-III deficiency was higher in patients with recurrent venous thrombosis.

AbstractBackground:Extracorporeal membrane oxygenation has been widely used after paediatric cardiac surgery due to increasing complex surgical repairs in neonates and infants having complex CHDs.Materials and methods:We reviewed retrospectively the medical records of all patients with CHD requiring corrective or palliative cardiac surgery at King Abdulaziz University Hospital that needed extracorporeal membrane oxygenation support between November 2015 and November 2018.Results:The extracorporeal membrane oxygenation population was 30 patients, which represented 4% of 746 children who had cardiac surgery during this period. The patients’ age range was from 1 day to 20.33 years, with a median age of 6.5 months. Median weight was 5 kg (range from 2 to 53 kg). Twenty patients were successfully decannulated (66.67%), and 12 patients (40%) were survived to hospital discharge. Patients with biventricular repair tended to have better survival rate compared with those with single ventricle palliation (55.55 versus 16.66%, p-value 0.058). During the first 24 hours of extracorporeal membrane oxygenation support, the flow rate was significantly reduced after 4 hours of extracorporeal membrane oxygenation connection in successfully decannulated patients.Conclusion:Survival to hospital discharge in patients requiring extracorporeal membrane oxygenation support after paediatric cardiac surgery was better in those who underwent biventricular repair than in those who had univentricular palliation. Capillary leak on extracorporeal membrane oxygenation could be a risk of mortality in patients after paediatric cardiac surgery.

During the current outbreak of coronavirus disease 2019 (COVID-19), Extracorporeal Membrane Oxygenation (ECMO) support could be considered as the rescue treatment from life threatening condition among severe COVID-19 patients who did not respond to mechanical ventilation. We propose that veno-venous ECMO should be considered if patient has persistence PaO2:FiO2 ratio lower than 100 mmHg after appropriate mechanical ventilator adjustment, muscle relaxant and prone position. During ECMO support, treatment against cytokine storm, including non-selective immune suppression with systemic steroid, or selective interleukin-6 inhibition and Janus Kinase inhibition should be considered. Heparin infusion is still the recommended anticoagulant to maintain activated partial thromboplastin time (APTT) ratio range 1.5-2.0. The overall hospital mortality was comparable with respiratory failure patients, requiring ECMO support from other causes, which was reported about 37-50%. The decision to initiate ECMO could be depended on the individual hospital capacity and treatment availability.

Abstract Introduction There is limited data on the impact of extracorporeal membrane oxygenation (ECMO) on pulmonary physiology and imaging in adult patients. The current study sought to evaluate the serial changes in oxygenation and pulmonary opacities after ECMO initiation. Methods Records of patients started on veno-venous, or veno-arterial ECMO were reviewed (n=33; mean (SD): age 50(16) years; Male: Female 20:13). Clinical and laboratory variables before and after ECMO, including daily PaO2 to FiO2 ratio (PFR), were recorded. Daily chest radiographs (CXR) were prospectively appraised in a blinded fashion and scored for the extent and severity of opacities using an objective scoring system. Results ECMO was associated with impaired oxygenation as reflected by the drop in median PFR from 101 (interquartile range, IQR: 63-151) at the initiation of ECMO to a post-ECMO trough of 74 (IQR: 56-98) on post-ECMO day 5. However, the difference was not statistically significant. The appraisal of daily CXR revealed progressively worsening opacities, as reflected by a significant increase in the opacity score (Wilk’s Lambda statistic 7.59, p=0.001). During the post-ECMO period, a >10% increase in the opacity score was recorded in 93.9% of patients. There was a negative association between PFR and opacity scores, with an average one-unit decrease in the PFR corresponding to a +0.010 increase in the opacity score (95% confidence interval: 0.002 to 0.019, p-value=0.0162). The median opacity score on each day after ECMO initiation remained significantly higher than the pre-ECMO score. The most significant increase in the opacity score (9, IQR: -8 to 16) was noted on radiographs between pre-ECMO and forty-eight hours post-ECMO. The severity of deteriorating oxygenation or pulmonary opacities was not associated with hospital survival. Conclusions The use of ECMO is associated with an increase in bilateral opacities and a deterioration in oxygenation that starts early and peaks around 48 hours after ECMO initiation.

Veno-venous extracorporeal membrane oxygenation is increasingly used for severe but potentially reversible acute respiratory failure in adults; however, there are limited data regarding long-term morbidity. At our institution, most patients requiring veno-venous extracorporeal membrane oxygenation have been followed up by a single physician. Our primary aim was to describe the serial long-term morbidity for respiratory, musculoskeletal and psychological functioning. A retrospective audit of inpatient and outpatient medical records was conducted. A total of 125 patients treated with veno-venous extracorporeal membrane oxygenation for primary respiratory failure were included. The patients were young (mean (standard deviation) age 43.7 (4.1) years), obese (mean (standard deviation) body mass index 30.8 (10.4) kg/m2), and mostly were male (59%). Most patients (60%) had no comorbidities. The survival rate to discharge was 70%, with body mass index and the number of comorbidities being independent predictors of survival on multiple logistic regression analysis. Over half (57%) of the Australian survivors had regular outpatient follow-up. They had a median of three reviews (range 1–9) over a median of 11.8 months (range 1.5-79) months. Breathlessness and weakness resolved in most within six months, with lung function abnormalities taking longer to resolve. Over half (60%) returned to employment within six months of discharge. Over a quarter (29%) displayed symptoms of anxiety, depression or post-traumatic stress disorder.
