Episode 51 - Persistent Inflammation, Immunosuppression & Catabolism Syndrome (PICS) with Dr. Scott Brakenridge
"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.
