The Bleeding Must Be Stopped! Management in the Situation of Hemorrhages-A Prospective Randomized Controlled Prospective Simulation Study

In a pre-hospital setting, uncontrolled hemorrhages in patients are undoubtedly a highly stressful situation for the rescuing medic, demanding prompt intervention. The effective stopping of a hemorrhage significantly reduces the risk of death for victims. The purpose of this study is to evaluate the students' chosen methods and the effectiveness of their actions during a simulated hemorrhage situation. In addition, the students' behavior and their cognitive overload classified using the NASA scale were also analyzed. The study enrolled 101 medical students, who were randomized and assigned sequentially to a study group ( = 49) and a control group ( = 52). The research group participated in a training course. Both groups then proceeded to a simulated hemorrhage scenario in a patient in a pre-hospital setting. Finally, the students assessed their cognitive overload using the NASA scale. After the training, more students have achieved effective bleeding control (36/49, 73.5% vs. 22/52, 42.3%, = 0.002). The prevalent method of bleeding control in both groups was using a tourniquet (97/101, 96%) with or without additional gauze and bandages. A significant improvement in the technique of the tourniquet application was observed-in the control group, 23/52 students (47.9%) applied it properly, while in the study group, it was 36/49 (73.5%). This resulted in a shorter time to achieve effective bleeding control and lower blood loss in the study group ( = 0.013 and = 0.034, respectively). The median blood loss was 32 mL (IQR = 24, range 11-65 mL) in the study group compared to 53 mL (IQR = 26, range 10-117 mL) in the control group. The education program for young medics needs changes, including an increased emphasis on learning procedures and improving practical skills.
