奶牛难产激发应激性急性肾上腺皮质功能不全——心衰、水电解质严重失调辩析

DYSFUNCTION OF ADRENALIN CORTEX INDUCED BY STRESSFUL DYSTOCIA OF DAIRY COWA—ANALYSIS OF HEART FAILURE AND SERIOUS IMBALANCE OF ELECTROLYTES

应激性急性肾上腺皮质功能不全症的病理机制十分复杂,目前人医的各类文献中大都以“垂体—肾上腺轴”功能不全、功能衰竭、或发生广泛性出血坏死性病演作解释。本病在奶牛分娩难产过程中并不少见,病牛的症状表现以心衰和失钠性低血症为主征。但在兽医临床上由于认识不足,曾有不少中外学者将奶牛产后卧地不起的各类疾病,含糊地统称为“母牛睡倒爬不起来综合征”;更由于救治不当,病牛常以淘汰或死亡告终。本文通过对一具体典型病例辨析,着重讨论了本病的基本病理反应和确立诊断依据,强调对本病救护施治时应遵循的基本原则,供同道们在分析和解决这一实际问题时参考。

The pathological mechanism of stressful dysfunction of adrenalin cortex is quite cimplicated. At present most papers in literature explain it in terms of dysfunction , failure and temperary illness of the piluitary adrenalin axis or extengive hemorrhagic necrosis. This disease is not rare during the process of dystocia. The chief symptons are heart failure and hyposodacmia from Na loss. However, during clinical practices because of lack of thorough under standing of the disease some scholars inside and outside China regard all the postpartum downer cow diseases as 'Downer Cow Syndrome'. But because of improper treatment the case is often ended up with cancelling of the cow or death. Through analysis of a typical case this paper discusses the fundamental pathological reactions of the disease and the basis for diagnosis, stressing the principles of treatment to foolow. This paper is presented as a reference for colleagues to tackle the problem with.
