Abstract

Routine diagnosis of pulmonary disorders in bovines by physical examination, hematology and radiography is not sufficient to establish confirmatory diagnosis. Tracheo-bronchial aspirates (TBA) can be used as a reliable sample for the diagnosis of lower respiratory tract affections in cattle. Percutaneous tracheo-bronchial aspirate sampling was performed in 173 standing conscious cattle using two types of catheters. Fifty four cows were sampled with Large Animal transtracheal wash Kit (MILA International, Inc. USA) and 119 with infant feeding tube. Cytologic analysis of TBA smears was performed to assess the diagnostic utility of samples. Diagnostic samples were obtained in 87.8 per cent cows (152/173). Sampling using commercial catheter and infant feeding tube retrieved diagnostic samples in 90.7 per cent and 86.6 per cent of cows, whereas repeated infusions were required in 61.2 per cent and 78.7 per cent of cases, respectively. None of the cows exhibited complications post sampling. Infant feeding tube (7 Fr) with 10 G steel introduction catheter was effectively used in the collection of TBA and was comparable with commercial catheter. Present communication reports first systematic study on collection of TBA by percutaneous method in adult pneumonic cattle.
收集肺炎牛气管支气管吸出物的新工作
通过体格检查、血液学检查和放射学检查对牛的肺部疾病进行常规诊断不足以确诊。气管支气管抽吸物(TBA)可作为诊断牛下呼吸道疾病的可靠样本。我们使用两种导管对 173 头站立清醒的牛进行了经皮气管支气管抽吸取样。其中 54 头牛使用大型动物经气管冲洗套件(美国 MILA 国际公司)采样,119 头牛使用婴儿喂养管采样。对 TBA 涂片进行细胞学分析,以评估样本的诊断效用。87.8%的奶牛(152/173)获得了诊断样本。使用商业导管和婴儿输液管采样的奶牛分别有 90.7% 和 86.6% 获得了诊断样本,而需要重复输液的分别占 61.2% 和 78.7%。没有一头奶牛在采样后出现并发症。婴儿喂食管(7 Fr)与 10 G 钢导管可有效用于采集 TBA,其效果与商用导管相当。这篇通讯首次报道了在成年气牛中通过经皮方法收集 TBA 的系统研究。
