Episode 51 - Persistent Inflammation, Immunosuppression & Catabolism Syndrome (PICS) with Dr. Scott Brakenridge Feb 11, 2022

"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.

This week on Rounds, we have several guest professors join us to discuss their perspectives and experience on managing patients with a difficult gallbladder. Joining us from Texas (and favoring subtotal cholecystectomy) are Drs. Sharmila Dissanaike and Michael Truitt. Drs. Angela Neville and Jessica Keeley from California discuss the merits of converting to an open cholecystectomy for patients with a difficult gallbladder.

Episode 41 - Acute Colonic Pseudo-Obstruction (aka Ogilvie's Syndrome) May 01, 2021

Bowel obstructions may be due to mechanical or functional causes. Although acute colonic pseudo-obstruction (ACPO) falls into the latter category, we must ALWAYS rule out mechanical causes for massive distension of the colon.
In this episode, we make our way down the GI tract and discuss the pathophysiology, risk factors, diagnostic and therapeutic considerations for what Dr. Ogilvie coined "Large-intestine Colic" in 1948.

Episode 40 - Acute Mesenteric Ischemia Apr 12, 2021

Whether due to occlusive or nonocclusive obstruction of the arterial inflow or obstruction of venous outflow, acute mesenteric ischemia (AMI) continues to be associated with high mortality rate. Early recognition based on a high index of suspicion is critical to early diagnosis and intervention, particularly among patients presenting with pain out of proportion to physical exam findings. In this episode, we discuss the pathophysiology of AMI, together with common causes, the initial clinical presentation, and management strategies for patients with this life-threatening and elusive surgical disease process.

Episode 31 - Who Should Manage Vascular Trauma? Nov 16, 2020

Who should be primarily responsible for managing vascular injuries? Trauma surgery? Vascular surgery? BOTH?! In this episode, we join the teams from the highly successful Behind the Knife and Audible Bleeding Podcasts to discuss the importance of a collaborative approach to the management of vascular trauma in an era marked by a decrease in general surgery resident experience with operative vascular trauma cases, together with an increase in the number of programs offering an integrated vascular surgery residency. Drs. Tanya Zakrison and Matt Martin (Team Trauma) debate Drs. Benjamin Starnes and Wesley Ohman (Team Vascular) on a topic that has brought about some "heated" exchanges on social media platforms such as Twitter.

Episode 30 - Acute Kidney Injury in the SICU with kidney_boy Dr. Joel Topf Oct 30, 2020

Dr. Joel Topf joins us on Rounds to discuss and review key concepts in the recognition and management of acute kidney injury (AKI) in the SICU. AKI is a common and morbid complication among hospitalized patients. Further, trauma and surgical patients, in particular, are at an increased risk for AKI due to the myriad of pre-, intra-, and postrenal insults that commonly occur at the time of injury, during resuscitation, surgery,, as well as from iatrogenic insults including IV contrast, NSAIDs, antibiotics (aminoglycosides and the infamous Pip/Tazo/Vanco ice cream sandwich).
From the use of a DDAVP clamp in patients with severe hyponatremia to the use of balanced solutions in critically ill patients, kidney_boy breaks it down for us as only a true salt whisperer can!

Episode 9 - The rEVOLUTION of ECMO May 08, 2020

What are the indications for ECMO beyond ARDS and refractory cardiogenic shock? In which patients should we consider eCPR and is this the new standard of care for patients sustaining out-of-hospital cardiac arrest? Finally, how do I work towards safely and efficiently weaning my patient from VV or VA ECMO?

These are just a few of the questions that we address on Rounds with our guest faculty member and Director of the UCLA Adult ECMO Program, Dr. Peyman Benharash. In this comprehensive review of ECMO we also explore the regionalization of ECMO care here in Los Angeles County, as well as the day-to-day considerations that you want to bear in mind when assessing and caring for your patients requiring extracorporeal life support.

Learning Objectives
By the end of rounds you should be able to:

1. Understand the indications & contraindications to VV and VA ECMO support

2. Describe the basic components of an ECMO circuit

3. Describe the role of eCPR in the management of adult patients with out-of-hospital cardiac arrest

4. Discuss key management strategies to safely wean patients from ECMO

5. Describe common complications of ECMO and strategies to mitigate them

Take Home Points

ECMO is time-sensitive, therefore, early and safe cannulation is an important determinant of outcome
ECMO is a bridge to therapy
Use of scoring systems like the Murray Score may be useful to stratify the severity of ARDS among patients being considered for VV ECMO support
The indications for ECMO are expanding to include technically challenging operative cases
eCPR is a promising therapy for patients presenting to an ECMO center of excellence with refractory VF/VT cardiac arrest
ECMO therapy, particularly VA ECMO, may affect virtually organ system
The potential role of ECMO therapy during the current COVID-19 pandemic remains to be defined

Episode 7 - Shock Talk I: Pathophysiology & Classification Apr 24, 2020

What is shock? A clear grasp of this concept is a MUST for any practitioner taking care of patients. Shock is many things. It is dynamic. It is elusive. It is lethal. A high index of suspicion is required to identify patients in shock. While lifesaving therapies are initiated, we must have an organized approach to to shock in order to identify the best diagnostic and therapeutic pathways for our patients. As such, we will review a simple classification system for shock. In a follow-up episode, we'll further examine the clinical presentation and management of patients presenting with hypovolemic, cardiogenic, distributive, or obstructive shock.
