13 Collapse The term ‘collapse’ is not specific to any one disorder or body system abnormality. All collapsed animals are recumbent but being able to classify them more specifically is important in order to allow appropriate emergency management to be instituted. In general, collapsed patients can be thought of in the following terms. Primary Cardiovascular Disorders Causing Collapse Cardiovascular causes of collapse centre on a lack of adequate tissue perfusion. This may be localized (e.g. feline aortic thromboembolism) but is typically generalized with the potential to cause inadequate perfusion of the brain, spinal cord and muscles. The majority of primary cardiovascular causes relate to primary cardiac dysfunction, for example: • Congestive heart failure and cardiogenic shock • Severe brady-dysrhythmia, e.g. sick sinus syndrome • Severe tachy-dysrhythmia, e.g. ventricular tachycardia in Boxer arrhythmogenic right ventricular cardiomyopathy • Congenital aortic stenosis in the German Shepherd dog. Primary Non-cardiovascular Disorders Causing Cardiovascular Collapse A wide range of disorders may cause collapse due to severe secondary cardiovascular compromise. These may include: • Hypovolaemic, maldistributive or obstructive shock (see Ch. 2) Only gold members can continue reading.
