If you're involved in the care of critically unwell patients then you will frequently encounter patients who are shocked. The European Society of Intensive Care Medicine defines shock as;
'Life-threatening, generalized form of acute circulatory failure associated with inadequate oxygen utilization by the cells. It is a state in which the circulation is unable to deliver sufficient oxygen to meet the demands of the tissues, resulting in cellular dysfunction.'
The assessment for shock needs to be part of the routine workup of every potentially unwell patient. Shock carries with it a high mortality rate, a range of meaningful interventions and the potential to make a real difference to our patients' outcomes.
In this podcast we cover
- Defining shock in adults
- Significance of shock
- What shock looks like
- A recap of cardiac physiology
- Causes of shock
- Ultrasound evaluation
- Fluid therapy
- Inotropes and vasopressors
As always we'd love to hear any thoughts or comments you have on the website and via twitter, we look forward to hearing from you.
Enjoy!
Simon, Rob & James
