The literature on diaphragmatic hernia in cattle and buffaloes is reviewed. A heifer showed accelerated respiration, symptoms of dyspnoea, occasional coughing and groaning, a variable appetite and emaciation unaccompanied by an increase in temperature for sixteen days prior to parturition. A diagnosis was not established. During parturition which occurred at term, marked symptoms were not observed, and it was decided to perform caesarian section because of the unduly large foetus. During the operation, performed in the standing animal, the heifer offered violent resistance when the abdominal cavity had been opened, showing symptoms of severe dyspnoea and/or pain, an fell down. In this state of excitement, which subsequently came to resemble shock, the heifer showed cyanotic mucosae and a very quick pulse. The heart sounds on the left side were inaudible on auscultation. The operation could only be completed in the recumbent position after sedation. Nothing which could account for the symptoms was detectable throughout treatment. The animal then remained quiet, the mucosae having regained their pink colour, the pulse rate decreased. Respiration continued to be too rapid and it became plain that it was obviously of the pendular type. The animal having been slaughtered in agreement with the owner, diaphragmatic hernia was found to be present on the left side. The enlarged spleen was largely situated in the thorax and partly adhered to the lung. The history of the case is discussed.
本文对牛和水牛膈疝的文献进行了综述。一头小母牛在分娩前16天出现呼吸加快、呼吸困难症状、偶尔咳嗽和呻吟、食欲不定以及消瘦，但体温未升高。未确诊。足月分娩时未观察到明显症状，因胎儿过大决定进行剖腹产。手术在站立的动物身上进行，打开腹腔时小母牛剧烈反抗，出现严重呼吸困难和/或疼痛症状，随后倒下。在这种类似休克的兴奋状态下，小母牛黏膜发绀，脉搏极快。听诊左侧心音听不到。镇静后只能在卧位完成手术。整个治疗过程中未发现任何能解释这些症状的原因。然后动物安静下来，黏膜恢复粉红色，脉搏率下降。呼吸仍然过快，显然是明显的摆动型呼吸。经与主人协商宰杀动物后，发现左侧存在膈疝。肿大的脾脏大部分位于胸腔，部分与肺粘连。对该病例的病史进行了讨论。
