Abstract

Introduction: It is important to have a venous line for infusion as an emergency treatment for patients suffering from crush syndrome or bleeding under confined space (CS) conditions in disaster medicine. However, it is not easy to for Emergency Life-Saving Technicians (ELSTs) to establish a venous line in such settings. Although previous studies have described the use of mechanical intraosseous (IO) devices and IO access while wearing chemical protection gears, problems for the use of IO devices under CS conditions have not been considered. This study aimed to investigate usefulness and problems of using a Bone Injection Gun™ (BIG) for IO infusion by ELSTs and rescue workers in CS conditions. Methods: The time required and success rate for IO infusion using a BIG in a manikin leg were measured, and for administering intravenous infusion in a manikin arm using either rescue gloves or plastic gloves by ELSTs or rescue workers under CS conditions. Results: Wearing rescue gloves, ELSTs were significantly faster in placing intraosseous infusion (IOI) compared with rescue workers. The success rate of the placement was not significantly different between ELSTs and rescue workers whether or not they wore rescue or plastic gloves. Conclusions: Although the finite usefulness of IOI with BIG under CS conditions is indicated, some problems such as the timing of removal of the IOI and difficulty in finding the location of the trocar needle after activating BIG are pointed out. Therefore, there are rooms to consider using IOI with BIG under CS condition.
