To all you medics out there. Has anyone ever used the Bone Injection Gun to gain Intraosseous access and then start rapid administration of fluids for casualties in hypervolemic shock. I've done some research and they claim the B.I.G is quicker at giving fluid resus than IV access. I've also got myself on a training course with an nhs hospital up north for use of the B.I.G. Thoughts, comments and opinions please.
