Abstract：
BACKGROUND: Bronchopneumonia (BP) in calves potentially causes systemic changes.
OBJECTIVE: To describe metabolic, arterial blood gas, and acid-base disorders in calves with BP diagnosed by thoracic ultrasound (TUS), Wisconsin score (WISC), and combinations of WISC and TUS.
METHODS: Two hundred thirty-one dairy preweaned dairy calves from 13 dairy farms.
METHODS: Cross-sectional study. Each calf sequentially underwent arterial blood gas evaluation, WISC score, venous sampling, and TUS. Calves were grouped based on a single diagnostic method and combination of WISC and 2 TUS cutoffs (≥1 cm; ≥3 cm) as healthy, upper respiratory tract infection, subclinical BP, and clinical BP.
RESULTS: Oxygenation and acid-base variables were unaffected. Glucose concentration in TUS-affected calves was significantly lower (P < .001) than in healthy calves (median ≥TUS1cm = 5.2 mmol/L 25%-75% interquartile range [IQR] 4.5-6.1,CONCLUSIONS: Clinical signs indicate minor systemic disorders compared to TUS. The abnormalities detected by ultrasonographic examination were moderate and did not deviate from normal reference ranges.

摘要：
背景：小牛支气管肺炎（BP）可能引起全身变化。
目的：描述代谢，动脉血气,和通过胸部超声（TUS）诊断为BP的小牛的酸碱紊乱，威斯康星州得分（WISC），以及WISC和TUS的组合。
方法：来自13个奶牛场的两百三十一只断奶前奶牛。
方法：横断面研究。每只小牛依次接受动脉血气评估，WISC得分,静脉取样,还有TUS.小牛根据单一诊断方法和WISC和2个TUS截断值(≥1厘米;≥3厘米)的组合被分组为健康的，上呼吸道感染,亚临床血压，和临床血压。
结果：氧合和酸碱变量不受影响。受TUS影响的小牛的葡萄糖浓度显着低于健康小牛（中位数≥TUS1cm=5.2mmol/L25％-75％四分位数范围[IQR]4.5-6.1，结论：与TUS相比，临床体征表明较小的全身性疾病。通过超声检查检测到的异常是中等的，并且没有偏离正常参考范围。
