Veno-venous extracorporeal membrane oxygenation (VV-ECMO) is a critical intervention for patients with severe lung failure, especially acute respiratory distress syndrome (ARDS). The weaning process from ECMO relies largely on expert opinion due to a lack of evidence-based guidelines. The ventilatory ratio (VR), which correlates with dead space and mortality in ARDS, is calculated as [minute ventilation (mL/min) x arterial pCO (mmHg)]/[predicted body weight × 100 × 37.

Background: Use of venovenous extracorporeal membrane oxygenation (ECMO) is increasing, but candidacy selection processes are variable and subject to bias.

Research Question: What are the reasons behind venovenous ECMO candidacy decisions, and are decisions made consistently across patients?

Study Design And Methods: Prospective observational study of all patients, admitted or outside hospital referrals, considered for venovenous ECMO at a tertiary referral center. Relevant clinical data and reasons for candidacy determination were cross-referenced with other noncandidates and candidates and were assessed qualitatively.

Article Synopsis
  • A 34-year-old man was in the hospital getting treated for an infection in his bone (called osteomyelitis).
  • He received his first dose of a medicine called ampicillin-sulbactam.
  • Unfortunately, he had a severe allergic reaction to the medicine, which caused him to sadly pass away.

A 25-year-old woman with severe tricuspid valve endocarditis and septic pulmonary emboli required VA-ECMO for recurrent hypoxemia-induced cardiac arrest. We present the clinical challenges requiring ECMO circuit reconfiguration and a percutaneous approach for vegetation debulking. ().

Adequate and durable recovery in patients supported with venoarterial (VA) extracorporeal membrane oxygenation (ECMO) can be challenging to predict. Extracorporeal membrane oxygenation weaning is the process by which the ECMO flows are decreased to assess if a patient is ready for decannulation. The optimal strategies for deciding who to wean and how to wean VA ECMO remain undefined.

And Background Data: VV ECMO can be utilized as an advanced therapy in select patients with COVID-19 respiratory failure refractory to traditional critical care management and optimal mechanical ventilation. Anticipating a need for such therapies during the pandemic, our center created a targeted protocol for ECMO therapy in COVID-19 patients that allows us to provide this life-saving therapy to our sickest patients without overburdening already stretched resources or excessively exposing healthcare staff to infection risk.

Methods: As a major regional referral program, we used the framework of our well-established ECMO service-line to outline specific team structures, modified patient eligibility criteria, cannulation strategies, and management protocols for the COVID-19 ECMO program.

Objective: The value of a simplified, focused intraoperative transesophageal echocardiography (TEE) protocol in patients undergoing liver transplantation (LT) is unknown. We sought to create and assess a 5-view LT TEE examination focused on 5 prespecified common causes of hypotension during LT.

Design: Retrospective cohort study.
