- Haemodynamics are complex and represent a teleological neurohormonal response to stress.
- Defence of MAP represents the balance between the afferent and efferent circulations and the compliance of the system.
- Monitoring is an aid to an overall assessment that must be considered within the clinical context and patient’s trajectory of illness.
- Catecholamines are hormones that are administered to augment inadequate endogenous responses.
- Synthetic catecholamines have no established role in clinical practice.
- Neurohormonal supplementation strategies have limited roles and should be confined to indications established from RCTs.
- Non-catecholamine inodilators have not been demonstrated to improve patient-centred outcomes in critically ill patients.
By the end of this lecture, the attendee will be able to:
- Understand the integration of cardiovascular physiology and pharmacology of drugs used to support the failing circulation.
- Recognise the limitations of derived and surrogate indices in determining haemodynamic function.
- Understand the role and application of endogenous catecholamine infusions in supporting the failing circulation.
- Understand the limitations of the use of synthetic vasoactive drugs in critically ill patients.

Professor John Myburgh
Professor John A Myburgh is Professor of Intensive Care Medicine, UNSW Sydney, Director of the Critical Care Division at the George Institute for Global Health and Senior Intensive Care Physician at the St. George Hospital, Sydney.
He has an internationally recognised reputation as a clinical researcher having conducted over 30 trials in fundamental aspects of Intensive Care Medicine including haemodynamic management, traumatic brain injury, sepsis and acute kidney injury. He established the ANZICS Clinical Trials Group with collaborators in 1994 and leads an internationally 2 recognised Intensive Care Medicine research program at the George Institute with extensive national and international networks. His research program is focussed on improving cost effective patient centred outcomes in critically ill patients through high-quality trials that are internationally generalisable.
