Implementation of a Standardized Transfusion Protocol for Cardiac Patients Treated With Venoarterial Extracorporeal Membrane Oxygenation Is Associated With Decreased Blood Component Utilization and May Improve Clinical Outcome.
Extracorporeal membrane oxygenation supplies oxygenated blood to the body supporting the heart and lungs. Survival rates of 20% to 50% are reported among patients receiving ECMO for cardiac arrest, severe cardiogenic shock, or failure to wean from cardiopulmonary bypass following cardiac surgery. Bleeding is one of the most common complications in ECMO patients due to coagulopathy, systemic anticoagulation, and the presence of large bore cannulas at systemic pressure. Absence of a standardized transfusion protocol in this population leads to inconsistent transfusion practices. Here, we assess a newly developed dedicated transfusion protocol in this clinical setting. ⋯ Our data indicate that implementation of a standardized transfusion protocol, using more restrictive transfusion indications in cardiac ECMO patients, was associated with reduced blood product utilization, decreased complications, and improved survival. This multidepartmental approach facilitates better communication and adherence to consensus clinical decision making between intensive care unit, surgery, and transfusion service and optimizes care of complicated and acutely ill patients.

Observational StudyAirway Management by Laryngeal Mask Airways for Cervical Tracheal Resection and Reconstruction: A Single-Center Retrospective Analysis.
Supraglottic airway devices (SADs) may have advantages over endotracheal intubation for tracheal resection and reconstruction in cases of severe and proximally located subglottic stenosis. This retrospective case series examines the feasibility of using SADs as a novel approach to airway management in tracheal resections. ⋯ This retrospective case series demonstrates the feasibility of using supraglottic airways alongside high-frequency jet ventilation for airway management in at least some cases of cervical tracheal resection and reconstruction. However, the small number of cases examined limits conclusions regarding indications, contraindications, and periprocedural safety.

The safety of anesthesia characteristic of high-income countries today is not matched in low-resource settings with poor infrastructure, shortages of anesthesia providers, essential drugs, equipment, and supplies. Health care is delivered through complex systems. Achieving sustainable widespread improvement globally will require an understanding of how to influence such systems. ⋯ This minimum (at least) should be available to all. Not only more resources, but also more equitable distribution of existing resources is required. Thus, the starting point for global access to safe anesthesia is acceptance that access to health care in general should be a basic human right everywhere.

Comparative StudySuperior Efficacy of Lipid Emulsion Infusion Over Serum Alkalinization in Reversing Amitriptyline-Induced Cardiotoxicity in Guinea Pig.
Tricyclic antidepressants (TCAs) are a major cause of fatal drug poisoning due to their cardiotoxicity. Alkalinization by sodium bicarbonate (NaHCO3) administration, the first-line therapy for TCA-induced cardiotoxicity, can occasionally yield insufficient efficacy in severe cases. Because most TCAs are highly lipophilic, lipid emulsion may be more effective than alkalinization. However, it remains to be determined whether lipid emulsion is more beneficial than alkalinization in reversing amitriptyline-induced cardiotoxicity. ⋯ Lipid emulsion significantly suppressed amitriptyline-induced INa, inhibition, which was likely related to the marked improvement in hemodynamic status observed in vivo and in isolated perfused hearts. These results suggest the superiority of lipid emulsion as the first-line therapy for TCA-induced cardiotoxicity compared to alkalinization therapy.
