The disintegration of charged alkaline mercury button cells in simulated gastric fluid over a 24 h period has been studied. The integrity of the cells and the amount of mercury that can leak out of them were assessed. The cells raised the pH of the incubating solutions. Disruption was seen in five out of 18 cells tested in 0.1 mol/L hydrochloric acid and one out of nine in 0.9% saline. Five of the six disrupted cells were made by the same manufacturer. Major leakage of mercury only occurred after complete disintegration of the cells. The implications of these findings for the management of patients who have ingested mercury-containing button cells are discussed.
研究了带电碱性汞纽扣电池在模拟胃液中24小时内的分解情况。评估了电池的完整性以及可能从电池中泄漏出的汞量。电池提高了孵育溶液的pH值。在0.1 mol/L盐酸中测试的18个电池中有5个出现破裂，在0.9%盐水中测试的9个电池中有1个出现破裂。6个破裂的电池中有5个是由同一制造商生产的。汞的大量泄漏仅在电池完全分解后才会发生。讨论了这些发现对摄入含汞纽扣电池患者管理的意义。
