To the Editor:—
Leighton and Mitchell 1describe methods for opening non–flip-top vials using sharp objects, such as a screwdriver, a ball pen, or a hemostat. We suggest an even better way for opening such vials by pushing hard on the cap center with a small, nonsharp object, such as the tip of a syringe, a hemostat, or even a shelf’s sharp edge (fig. 1). This prevents the need for the exact insertion of the sharp object into the gap between the cap and its center.
Although we were unable to obtain dantrolene bottles, we tested this method on 25 outdated non–flip-top vials. All were opened easily within less than 2 s. Use of this method will allow faster opening of vials and will prevent injury in an emergency.
