The management of a broken short 30-gauge hypodermic needle after an inferior alveolar dental nerve block in a 3-year-old child is discussed. Because of the possibility of the needle migrating toward vital structures, and because of the psychologic and medicolegal implications that could arise, we believed that the needle should be immediately removed with surgical procedures.
讨论了一名3岁儿童在下牙槽神经阻滞麻醉后折断的30号短皮下注射针头的处理方法。由于针头有可能向重要结构移动，且可能产生心理和法医学方面的影响，我们认为应立即通过外科手术取出针头。
