Management of Hypotension during Anaesthesia


This session will review the management of perioperative hypotension, with a special focus on evidence challenging traditional intravenous fluid strategies. Hypotension is a commonly encountered complication association with anaesthesia and surgery that can cause hypoperfusion and inadequate deliver of oxygen and substrates to organ systems. Recognition and correction of hypotension is time critical, especially in patients with pre-existing comorbidities that compromise organ perfusion. There is evidence that adverse outcomes including renal, cardiovascular, central nervous system damage, and death, may be linked to prolonged episodes of perioperative hypotension-related-hypoperfusion.

The widespread adoption of blood pressure monitoring devices across veterinary practice has seen interest in this topic grow, as practitioners struggle to find consensus on how, and when to treat the hypotensive patient. Despite the high incidence of perioperative hypotension, there are few comprehensive resources available in the literature to guide the management of this common clinical occurrence. Furthermore, there is growing evidence that the traditional approach to the management of these patients using intravenous fluid therapy may be doing more harm than good.

This session will review the aetiology, assessment and therapeutic management of perioperative hypotension, with a special focus on recent evidence challenging traditional intravenous fluid resuscitation strategies.

Learning Objectives

The goal of this webinar is to provide veterinary and nursing providers of anaesthesia with the knowledge needed to:

· Understand the clinical implications of hypotension

· Recognise hypotension in the anaesthetised patient

· Treat hypotension from a physiologically sound and clinically practical context

· Understand recent paradigm shifts relating to the role of intravenous fluids in the perioperative setting
