抄録

Many cases of tissue injury caused by a button battery appearing as a foreign body have been reported in the otolaryngology field. However, there have been very few studies on the mechanism of tissue injury by batteries.<BR>In this study, we inserted a button-type battery into 4cm3of Ringer's solution, which is similar to serous fluid, at both room temparature (20°C) and body temparature (37°C), and observed the electro-chemical reactions between the negative and positive terminals over 6 hours. We identified the products of these reactions, measured the remaining electromotive force (EMF), and observed the changes in pH and metallic ion concentrations over time.<BR>In conclusion, the following three major groups of factors causing tissue injury were suggested:<BR>1) At the positive terminal the HCl acid and HClO produced broke down, and chlorine gas was dissolved into the solution.<BR>2) At the negative terminal, the OH-radical was produced by reduction of water.<BR>3) Postassium hydoxide (KOH), nickel (Ni2+) manganse (Mnn+), chrome (Crn+), and lead (Pb2+) leaked from the battery at the poles, due to oxidation, and were partially dissolved in the serous fluid. These factors may result in serious tissue injury. In addition, each electro-chemical reaction occured in a very short time at these relatively high temperatures, and as a result, may be the cause of these tissue injuries.
