Bradycardia DDx
Bradycardia differential diagnosis. Bradycardia refers to heart rate <60/min in an adult; Bradycardias are classified as regular or irregular, narrow complex or wide complex; The underlying causes of bradycardia are legion
Post Cardiac Arrest Care
Post Cardiac Arrest Care: Priorities are prevent further cardiac arrest; define the underlying pathology; limit organ damage; predict non-survivors
Prognosis After Cardiac Arrest
Prognosis After Cardiac Arrest incolves: the underlying cause of cardiac arrest (e.g. overdose vs dilated cardiomyopathy); presence of co-morbidities (e.g. metastatic cancer, dementia); use of targeted temperature management (therapeutic hypothermia); features of the the cardiac arrest and cardiovascular and neurological assessment
Post-cardiac arrest syndrome
Post-cardiac arrest syndrome (aka post-resuscitation syndrome). Occurs after return of spontaneous circulation (ROSC) following cardiorespiratory arrest and involves multiple systems
Reflects a state of whole-body ischaemia and subsequent reperfusion
Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis
= immune complex mediated hypersensitivity -> severe erythema multiforme. Separation of the epidermis from the dermis; most authors believe toxic epidermal necrolysis (TEN) and SJS are different ends of the same spectrum of disease
Serious Generalised Skin Disorders
Serious Generalised Skin Disorders: Mnemonic: PTSD-D
Purpura Fulminans
CAUSES Meningococcal disease Post-splenectomy pneumococcaemia DIC Rickettsial infections High dose inotropes Endocarditis Venom-induced consumptive coagulopathy (VICC) due to snakebite
Precautionary Principle and the Kehoe Principle
The Precautionary Principle (The absence of evidence of risk = a possibility of risk until proven otherwise) and Kehoe Principle (The absence of evidence of risk = Evidence of the absence of risk) reflect different conceptions of risk in the absence of evidence
Neurogenic pulmonary oedema
Neurogenic pulmonary edema (NPE) is a clinical syndrome characterized by the acute onset of pulmonary edema following a significant central nervous system (CNS) insult
Nitric Oxide
Nitric Oxide: inhalational agent (inhaled nitric oxide, iNO); an inorganic gas - potent, selective pulmonary vasodilator of those areas of the lung being ventilated
Tissue Oxygenation Assessment
Tissue Oxygenation Assessment
Electrical Impedance Tomography
Electrical impedance tomography (EIT) is a noninvasive, radiation-free monitoring tool that allows real-time imaging of ventilation
EIT has medium spatial resolution and a very high temporal resolution
