Pharyngeal trauma in cattle can occur during the administration of oral medication using a balling gun. The number of cases of severe complications due to bolus application that have been referred to our hospital has increased from nil between 1996 and 2008 to three or four per year. In our experience, reports by bovine veterinarians of patients with severe and often fatal pharyngeal trauma, which were not referred to the clinic, have become more common in recent years as well. The incidence of this complication is likely to be higher than this number of referrals suggests. Diagnosis without the help of imaging techniques, such as radiography and endoscopy, may be difficult, especially in cases where exploration of the pharynx cannot be carried out, or is unable to confirm the absence or presence of a lesion. Prognosis is often poor in cases where perforation has been confirmed. Boluses are increasingly administered by the owners or farm personnel without the supervision of a veterinarian. In order to prevent losses due to balling gun-induced injuries, the veterinarian plays a crucial role in giving advice to his clients. Five cases of cattle suffering from varying degrees of balling gun-induced trauma are presented, and consideration is given to incorrect application techniques.
牛的咽部创伤可在使用投丸枪进行口服给药时发生。自 1996 年至 2008 年期间，我院每年转诊的因投丸而导致严重并发症的病例数从无增加到 3 至 4 例。根据我们的经验，近年来，兽医报告的严重且常常致命的咽部创伤病例越来越多，但这些病例并未转诊至我们的诊所。这种并发症的发生率可能高于转诊病例数所表明的。如果没有 X 光和内窥镜等成像技术的帮助，诊断可能很困难，特别是在无法进行咽部探查，或者无法确定是否存在病变的情况下。一旦确认穿孔，预后通常较差。投丸枪的使用越来越多是由畜主或农场工作人员进行的，而不是在兽医的监督下进行。为了防止因投丸枪引起的伤害而造成损失，兽医在向客户提供建议方面发挥着至关重要的作用。本文介绍了 5 例不同程度的因投丸枪而导致创伤的牛，并考虑了不正确的应用技术。
