Rescue therapy for hypercapnia due to high PEEP mechanical ventilation in patients with ARDS and renal failure.

Extracorporeal removal of carbon dioxide in patients experiencing severe hypercapnia due to lung protective mechanical ventilation was first described over four decades ago. There have been many devices developed and described in the interim, many of which require additional training, resources, and staff. This manuscript describes a readily available and relatively simple adjunct that can provide partial lung support in patients with acute respiratory distress syndrome complicated by severe hypercapnia and acute kidney injury requiring dialysis.

A Weaning Protocol for Venovenous Extracorporeal Membrane Oxygenation With a Review of the Literature.

Several articles have discussed the weaning process for venoarterial extracorporeal membrane oxygenation; however, there is no published report to outline a standardized approach for weaning a patient from venovenous extracorporeal membrane oxygenation (ECMO). This complex process requires an organized approach and a thorough understanding of ventilator management and ECMO physiology. The purpose of this article is to describe the venovenous ECMO weaning protocol used at our institution as well as provide a review of the literature.

The Impact of an Advanced ECMO Program on Traumatically Injured Patients.

In June 2016, an advanced extracorporeal membrane oxygenation (ECMO) program consisting of a multidisciplinary team was initiated at a large level-one trauma center. The program was created to standardize management for patients with a wide variety of pathologies, including trauma. This study evaluated the impact of the advanced ECMO program on the outcomes of traumatically injured patients undergoing ECMO. A retrospective cohort study was performed on all patients sustaining traumatic injury who required ECMO support from January 2014 to September 2017. The primary outcome was to determine survival in trauma ECMO patients in the two timeframes, before and after initiation of the advanced ECMO program. Secondary outcomes included complication rates, length of stay, ventilator usage, and ECMO days. One hundred and thirty eight patients were treated with ECMO during the study period. Of the 138 patients, 22 sustained traumatic injury. Seven patients were treated in our pre-group and 15 in our post-group. The majority of patients were treated with VV ECMO. Our post group VV ECMO extracorporeal survival rate was 64% and our survival to discharge was 55%. This study demonstrated an improvement in survival after implementation of our advanced ECMO program. The implementation of a multidisciplinary trauma ECMO team dedicated to the rescue of critically ill patients is the key for achieving excellent outcomes in the trauma population.

The Use of Extracorporeal Membrane Oxygenation for Acute Respiratory Distress Syndrome in Severe Burns Without Inhalation Injury.

Burn injury results in a severe systemic inflammatory response which is associated with the development of acute respiratory distress syndrome (ARDS), even without associated inhalation injury. Venous-venous extracorporeal membrane oxygenation (VV-ECMO) has been implemented in various cases of ARDS to provide support and allow for protective lung ventilation strategies. We report the case of a 27-year-old man presenting with a 60% total body surface area partial thickness burn who developed refractory ARDS with Murray Score of 3.75. ECMO was initiated on hospital day 9 for a total of 10 days with concurrent lung-protective ventilation. He subsequently recovered and was discharged on hospital day 48. ECMO should be considered as an adjunctive strategy in burn patients without inhalation injury to minimize ventilator-induced lung injury when high levels of support are needed to achieve adequate ventilation in patients with ARDS.
