Abstract
Rescue treatments for status asthmaticus remain limited. Current literature has mainly focused on using extracorporeal membrane oxygenation (ECMO) as a primary modality of care for these patients. Low-flow extracorporeal CO 2 removal (ECCO 2 R) systems are an attractive option to improve refractory hypercapnic respiratory acidosis because of status asthmaticus. This is a retrospective case series that describes the feasibility and efficacy of the use of a low-flow ECCO 2 R device, the Hemolung Respiratory Assist System, in patients with refractory hypercapnic respiratory failure because of status asthmaticus. Eight patients were treated with the Hemolung Respiratory Assist System in eight separate locations globally. Seven (88%) of the patients survived to discharge in this case series. Both CO 2 and pH resolution were seen in 6 hours. None of the ECCO 2 R runs were stopped because of mechanical- or device-related complications. One patient necessitated transition to ECMO. Low-flow ECCO 2 R systems is an effective option for resolution of refractory hypercapnia in status asthmaticus. Use of these systems are also associated with a survival rate of close to 90% in patients with status asthmaticus.

Crit Care 2024; 28:146.

Abstract
PURPOSE A systematic review and meta-analysis to evaluate the impact of extracorporeal carbon dioxide removal (ECCO2R) on gas exchange and respiratory settings in critically ill adults with respiratory failure. METHODS We conducted a comprehensive database search, including observational studies and randomized controlled trials (RCTs) from January 2000 to March 2022, targeting adult ICU patients undergoing ECCO2R. Primary outcomes were changes in gas exchange and ventilator settings 24 h after ECCO2R initiation, estimated as mean of differences, or proportions for adverse events (AEs); with subgroup analyses for disease indication and technology. Across RCTs, we assessed mortality, length of stay, ventilation days, and AEs as mean differences or odds ratios. RESULTS A total of 49 studies encompassing 1672 patients were included. ECCO2R was associated with a significant decrease in PaCO2, plateau pressure, and tidal volume and an increase in pH across all patient groups, at an overall 19% adverse event rate. In ARDS and lung transplant patients, the PaO2/FiO2 ratio increased significantly while ventilator settings were variable. "Higher extraction" systems reduced PaCO2 and respiratory rate more efficiently. The three available RCTs did not demonstrate an effect on mortality, but a significantly longer ICU and hospital stay associated with ECCO2R. CONCLUSIONS ECCO2R effectively reduces PaCO2 and acidosis allowing for less invasive ventilation. "Higher extraction" systems may be more efficient to achieve this goal. However, as RCTs have not shown a mortality benefit but increase AEs, ECCO2R's effects on clinical outcome remain unclear. Future studies should target patient groups that may benefit from ECCO2R.

Abstract
BACKGROUND In this narrative review we aimed to explore outcomes of extracorporeal life support (extracorporeal membrane oxygenation (ECMO) and extracorporeal carbon dioxide removal (ECCO2R)) as rescue therapy in patients with status asthmaticus requiring mechanical ventilation. METHODS Multiple databases were searched for studies fulfilling inclusion criteria. Articles reporting mortality and complications of ECMO and ECCO2R in mechanically ventilated patients with acute severe asthma (ASA) were included. Pooled estimates of mortality and complications were obtained by fitting Poisson's normal modeling. RESULTS Six retrospective studies fulfilled inclusion criteria thus yielding a pooled mortality rate of 17% (13-20%), pooled risk of bleeding of 22% (7-37%), mechanical complications in 26% (21-31%), infection in 8% (0-21%) and pneumothorax rate 4% (2-6%). CONCLUSION Our review identified a variation between institutions in the initiation of ECMO and ECCO2R in patients with status asthmaticus and discrepancy in the severity of illness at the time of cannulation. Despite that, mortality in these studies was relatively low with some studies reporting no mortality which could be attributed to selection bias. While ECMO and ECCO2R use in severe asthma patients is associated with complication risks, further studies exploring the use of ECMO and ECCO2R with mechanical ventilation are required to identify patients with favorable risk benefit ratio.

Abstract
Extracorporeal carbon dioxide removal (ECCO2R) is a form of extracorporeal life support (ECLS) largely aimed at removing carbon dioxide in patients with acute hypoxemic or acute hypercapnic respiratory failure, so as to minimize respiratory acidosis, allowing more lung protective ventilatory settings which should decrease ventilator-induced lung injury. ECCO2R is increasingly being used despite the lack of high-quality evidence, while complications associated with the technique remain an issue of concern. This review explains the physiological basis underlying the use of ECCO2R, reviews the evidence regarding indications and contraindications, patient management and complications, and addresses organizational and ethical considerations. The indications and the risk-to-benefit ratio of this technique should now be carefully evaluated using structured national or international registries and large randomized trials.
