A retrospective study on 159 cesareans on dairy cows referred between 1985 and 1989 to the veterinary teaching hospital is reported. The objective of the study was to evaluate the probability and the factors associated with survival and subsequent calving. The risk of dying for the cows was 24% following surgery. The risk of dying differed if the cow had an emphysematous, dead, or live calf; it was 63%, 21%, and 14%, respectively. Of all the cows returned to the farm and for which there was a breeding recorded, 64% calved again. But only 28% of all the cows returned home and, therefore, only 17% of all the referred cases calved again. We used multivariate analysis to obtain a predictive model on prognosis following surgery. The prognosis was only influenced by the calf condition at admission.
本文报道了一项对1985年至1989年间转诊至兽医教学医院的159头奶牛剖腹产手术的回顾性研究。该研究的目的是评估奶牛存活及随后产犊的概率和相关因素。术后奶牛的死亡风险为24%。如果奶牛产出的是气肿犊牛、死胎或活犊，其死亡风险会有所不同，分别为63%、21%和14%。在所有返回农场且有繁殖记录的奶牛中，64%再次产犊。但所有返回农场的奶牛中只有28%，因此，在所有转诊病例中只有17%再次产犊。我们使用多变量分析来建立术后预后的预测模型。预后仅受入院时犊牛状况的影响。
