Description
INTRODUCTION: The American College of Surgeon’s Stop the Bleed campaign’s Bleeding Control Basic (ACS-BCon) course was established to transform bystanders into immediate responders in situations where life-threatening hemorrhage occurs. The 90-minute course is intended for lay persons without medical knowledge or training and includes a didactic presentation followed by a practicum that involves management of a bleeding wound in a simulator. We sought to ascertain whether course participants believe that their training would have been more beneficial with active bleeding simulation. METHODS: Live survey immediately before and following BCon courses conducted between August 2018 and April 2019. Those who volunteered to complete the survey were presented a 4-question survey regarding their experience with the BCon training via a center that routinely used flowing bleeding simulation in all of their courses (Wet Group) and one that did not (Dry Group). The practicum utilizes a small model wound made of synthetic material to simulate a wound of the type that would require packing with gauze to achieve cessation of blood loss (Wound-in-a- BoxTM, Techline Technologies, Inc.). It is designed to be connected to a bleeding system consisting of a fluid reservoir (with dyed or undyed water) contained within a pressure bag (Blood Supply PumpTM) which allows fluid to be delivered through the wound at an arterial pressure simulating human bleeding. There is no mandate from the ACS to use the flowing fluid and pump. While utilization of flowing fluid and pump more realistically simulates active bleeding, many sites prefer to avoid the its use as this adds to the workload of course personnel. RESULTS: Sixty participants completed the survey, with one participant in Wet Group opting out of completing the survey (1.6% total, 2% of the Wet Group). Of the 60 respondents, 46 participated in a wet training and 14 participated in a dry training. In the wet group, 41 of 46 subjects (89%) indicated that they do not believe the course would have been more beneficial had they trained with the dry wound. In the dry group, 8 of 14 respondents (57%) indicated that they believe the course would have been more beneficial had they trained with a wet wound. CONCLUSIONS: Regardless of the type of wound used, the majority of subjects preferred the idea of using an actively bleeding wound simulation versus a dry simulation, suggesting that participants would prefer a more realistic simulation during training. Whether this preference translates to greater competence and confidence in emergency bleeding situations is the subject of further analyses.
