Four cases of pharyngeal trauma in cattle due to improper administration of oral medications are discussed. These cases presented for suspected gastro-intestinal disorders and anorexia. Physical findings included copious drooling of saliva, pharyngeal pain, extended head and neck, forestomach stasis, fever, dysphagia, and pneumonia. Diagnosis was made by manual examination of the oral cavity or endoscopy. Ancillary diagnostic aids included clinical pathology and radiography. Hemograms were consistent with infection, serum electrolytes were normal. Radiographs in 3 of 4 did reveal significant evidence of retropharyngeal cellulitis. The signs of dysphagia and forestomach dysfunction were explained by either a pain induced inhibition of swallowing and eructation or direct involvement of the vagus nerve itself in the retropharyngeal region. An additional consequence of laryngeal motor dysfunction was aspiration pneumonia. Response to treatment with broad spectrum antibiotics, analgesics and symptomatic supportive care over a 7 to 14 day period was good.
本文讨论了4例因口服药物给药不当导致的牛咽创伤病例。这些病例因疑似胃肠疾病和厌食前来就诊。体格检查发现包括大量流涎、咽部疼痛、头颈伸展、前胃停滞、发热、吞咽困难和肺炎。通过口腔手动检查或内窥镜检查进行诊断。辅助诊断方法包括临床病理学和放射学检查。血常规结果与感染相符，血清电解质正常。4例中有3例的X光片显示有明显的咽后蜂窝织炎迹象。吞咽困难和前胃功能障碍的症状可解释为疼痛引起的吞咽和嗳气抑制，或迷走神经本身直接累及咽后区域。喉运动功能障碍的另一个后果是吸入性肺炎。在7至14天的时间内，使用广谱抗生素、镇痛药和对症支持治疗的反应良好。
