Fulminant sepsis secondary to severe lung contusion from the Lund University Cardiopulmonary Assist System device.

INTRODUCTION: Portable mechanical chest compression devices have been developed to improve upon many problems of manual compression, increase patient survival, and improve neurologic outcomes. However, the use of these devices is not without risk of harm to the patient. CASE REPORT: We describe a patient who received chest compressions from a mechanical compression device after cardiac arrest and subsequently developed fulminant sepsis secondary to lung contusions and a necrotizing pulmonary infection. DISCUSSION: Although injuries from the LUCAS have been reported, we believe this is the first reported fatal complication related to direct pulmonary injury from a mechanical compression device. CONCLUSION: More investigation is needed to determine the safety and efficacy of the LUCAS especially in obese patients.

Voxelotor as a Treatment of Persistent Hypoxia in the ICU.

Hypoxia is encountered frequently in the ICU as a result of a wide range of pathologic characteristics. The oxygen-hemoglobin dissociation curve describes hemoglobin's affinity for a given Po2 and factors affecting uptake and offload. Research in manipulating this relationship between hemoglobin and oxygen is sparing. Voxelotor is a hemoglobin oxygen-affinity modulator that is approved by the US Food and Drug Association for use in the management of sickle cell disease. We present two patients without sickle cell disease who underwent treatment with this novel agent to assist with chronic hypoxia and weaning of mechanical support.

Superior vena cava syndrome during veno-venous extracorporeal membrane oxygenation for COVID-19.

Superior vena cava (SVC) syndrome is typically associated with malignant tumors obstructing the SVC, but as many as 40% of cases have other etiologies. SVC obstruction was previously described during veno-venous extracorporeal membrane oxygenation therapy (VV ECMO) in children. In this report, we describe a woman with adult respiratory distress syndrome resulting from infection with coronavirus-19 who developed SVC syndrome during VV ECMO. A dual-lumen ECMO cannula was inserted in the right internal jugular vein, but insufficient ECMO circuit flow, upper body edema, and signs of hypovolemic shock were observed. This clinical picture resolved when the right internal jugular vein was decannulated in favor of bilateral femoral venous cannulae. Our report demonstrates that timely recognition of clinical signs and symptoms led to the appropriate diagnosis of an uncommon ECMO complication.
