In this episode, we talk all things critical care the one and only, Dr. Jean-Louis Vincent aka. JLV.  This episode is a MUST listen. We touch upon the evolution of early goal directed therapy, measures of fluid responsiveness, optimizing oxygen delivery, and the importance of integrating data points versus examining  them in isolation when caring for our critically ill and injured patients. This and MUCH MUCH more in arguably one of my favorite episodes to date!!

It's been a while! We are coming to you from our new studio in Victoria on Vancouver Island, BC. This Season is PACKED with incredible content, interviews and educational pearls designed to improve the quality of care that you are deliver daily at the bedside to your patients and their loved ones.

"Getting patients resuscitated through sepsis, septic shock, and hemorrhagic shock is not the end...it's the beginning."

In this episode, Dr. Brakenridge from Harborview Medical Center joins us to discuss PICS and the impact of this syndrome on our critically ill and injured patients and their families. Also referred to as the Post-Intensive Care Syndrome, Dr. Brakenridge shares with us the evolution and results of translational research into this now well-recognized morbid condition which often occurs in the setting of chronic critical illness. From the importance of breaking  the cycle of "sepsis recidivism" to the. application of the SCCM A to F bundle, this episode is a MUST listen for those of us taking care of patients in the ICU.

In this, our 50th episode, we are in Austin, TX, for the Annual EAST Scientific Meeting where we are joined by Dr. Bryan A. Cotton who shares his expertise and knowledge regarding the use of whole blood (WB) in trauma patients. From the use of whole blood in prior military conflicts to the design and successful implementation of one of the only prospective randomized controlled trials of modified whole blood use in trauma patients, Dr. Cotton provides an incredible overview of the potential benefits of whole blood or as he refers to it - "the dying blood product". Also covered in expert fashion are the role of other hemostatic products and strategies including tranexamic acid, fibrinogen concentrates, and a plasma first resuscitation strategy.
