Another application has been tested for Transcranial Direct Current Stimulation (tDCS)—a “bioelectric medicine” device. This time it has been applied to curb bleeding. It may be particularly helpful with internal bleeding which is as life-threatening as external and harder to stop.
Applying the current to the vagus nerve which connects the brain to the vital organs “would then trigger the spleen to release blood-clotting platelet cells and send them to areas in need.” The device will be used in a clinical trial “as a treatment for postpartum hemorrhage (a leading cause of maternal death worldwide)”. And it “could theoretically be used … as a blood loss prevention strategy during surgery.”
