Purpose: The management of bronchial fistula associated with acute lung injury raises two major concerns: (1) high ventilation pressures are necessary for lung recruitment but detrimental for fistula healing, and (2) adequate lung recruitment is prevented by large air leak. Primary surgical closure of bronchial fistula should be attempted but is rarely successful during mechanical ventilation. We sought to evaluate the efficacy of extracorporeal membrane oxygenation associated with lung-protective ventilation in case of failure of conventional management.
Description: Arteriovenous extracorporeal membrane oxygenation was initiated by femorofemoral cannulation. A stepwise increase of extracorporeal membrane oxygenation output and a decrease of mechanical ventilation settings were simultaneously performed, aiming at lung-protective ventilation.
Evaluation: During a 1-year period, this protocol management was used in 5 patients with refractory respiratory failure associated with bronchial fistula after thoracic operations. This strategy allowed fistula healing in 3 patients.
Conclusions: If correctly timed, extracorporeal membrane oxygenation can provide a therapeutic bridge to lung-protective ventilation and allow bronchial fistula healing in case of refractory respiratory failure.

Introduction: This systematic review aims to evaluate the optimal management of acute respiratory distress syndrome (ARDS) in critically ill surgical patients, specifically focusing on positioning, extracorporeal membrane oxygenation (ECMO) use, ventilation, fluid resuscitation, and pharmacological treatments.
Methods: A systematic review was conducted utilizing four databases including PubMed, Google Scholar, EMBASE, and ProQuest. This study followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and was registered with The International Prospective Register of Systematic Reviews.
ECMO-assisted bilateral uniportal thoracoscopic carinal resection and reconstruction: a case report.

Background: Carinal resection and reconstruction are complex surgical procedures often necessitated by tumors or other pathologies involving the tracheobronchial junction. Traditional approaches to these surgeries are highly invasive. The advent of uniportal video-assisted thoracoscopic surgery (VATS) along with the integration of extracorporeal membrane oxygenation (ECMO) offer potential advantages in reducing surgical trauma and improving outcomes.

Background: The long-term effects of early left ventricular unloading after venoarterial extracorporeal membrane oxygenation (VA-ECMO) remain unclear.
Methods: The EARLY-UNLOAD trial was a single-center, investigator-initiated, open-label, randomized clinical trial involving 116 patients with cardiogenic shock (CS) undergoing VA-ECMO. The patients were randomly assigned to undergo either early routine left ventricular unloading by transseptal left atrial cannulation within 12 hours after randomization or the conventional approach, which permitted rescue transseptal cannulation in case of an increased left ventricular afterload.

Introduction: Infectious disease treatments are transitioning from a one-size-fits-all approach to a more tailored approach. The increasing adoption of therapeutic drug monitoring (TDM) of antimicrobials is a clear example of this trend. Routine antimicrobial TDM in critically ill patients should be mandatory.

Whilst Extra-Corporeal Membrane Oxygenation (ECMO) for circulatory support in patients with severe septic shock, commenced in newborn infants and children in the late 1980's, ECMO has remained a controversial treatment for adults with refractory septic shock (RSS). This is fundamentally due to differences in the predominant hemodynamic response to sepsis. In newborn infants and very young children ventricular failure called Low Cardiac Output Syndrome (LCOS) is the major hemodynamic response whilst adolescents and adults have mainly vasoplegic shock.
