Episode 40 - Acute Mesenteric Ischemia
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 39 - Necrotizing Soft Tissue Infections (NSTIs)
Rare. Morbid. Lethal. NSTIs area group of infections which result in aggressive tissue destruction, systemic toxicity, and can involve any layer of the soft tissue. The key to successful management (like so many disease processes) is having a high index of suspicion together with administration of early, broad-spectrum antibiotics and surgery.

Episode 38 - Cricothyrotomy Considerations with Scott Weingart
Dr. Scott Weingart joins us on Rounds to discuss a topic that's of great interest to the both of us - surgical cricothyroidotomy.

Episode 31 - Who Should Manage Vascular Trauma?
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
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
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.

Episode 8 - Tracheostomies Demystified
Is there an ideal time to place a tracheostomy? What factors might influence my decision to proceed with an open versus percutaneous tracheostomy? In this episode, we discuss common perioperative considerations influencing our decision to proceed with tracheostomy in critically ill patients requiring prolonged mechanical ventilation. Over the course of rounds, I'll share with you some "tricks of the trade" and review key management principles for safely dealing with potentially life-threatening tracheostomy complications in the postoperative period including unplanned early decannulation and bleeding.

Episode 7 - Shock Talk I: Pathophysiology & Classification
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.
Apr 16, 2020
Episode 6 - Acute Respiratory Failure II: Recognition, Management & Oxygen Therapies
This episode follows-up on Episode 1 and focuses on the assessment and initial treatment of patients with acute respiratory failure. Through a focused clinical exam, we can identify signs of increased work of breathing which should alert us to the need for support in the form of oxygen and ventilatory therapies. The 3 major types of oxygen delivery systems are also discussed including low- and high-flow, as well as reservoir systems.
Apr 12, 2020
Episode 5 - The Deadly Dozen of Thoracic Trauma
In this episode we review the "lethal 6" and "hidden 6" chest injuries that comprise the *deadly dozen of thoracic trauma*. Mechanism of injury together with vital signs and findings from the physical exam should provide us with the data needed to identify life-threatening thoracic injuries on our primary survey. For hidden injuries, the diagnostic adjuncts required to identify these injuries are also discussed.
Apr 6, 2020
Episode 4 - Endpoints of Resuscitation
Dr. Matt Martin from Scripps Mercy Hospital in San Diego, CA joins us on Rounds to discuss topics related to the resuscitation of critically injured patients with a focus on endpoints of resuscitation. The basic approach to the assessment of "sick" versus "not sick" patients and utility of early transfusion of whole blood are explored, along with the usefulness of physical exam findings and other adjuncts in guiding our resuscitation efforts.
Apr 3, 2020
Episode 3 - Basic Mechanical Ventilation I: Fundamentals
In this episode we review and discuss the core physiologic concepts required to understand basic mechanical ventilation. By examining the respiratory equation of motion or force balance equation, we'll gain insight into the pressures that need to be generated to deliver a positive pressure breath and those pressures that can be monitored during the care of vented patients. This will form the groundwork for Basic Mechanical Ventilation II: Modes of Ventilation.

Apr 3, 2020
Episode 1 - Acute Respiratory Failure I: Mechanisms & Pathophysiology
In this, our inaugural episode, we explore common mechanisms underlying acute hypoxemic and hypercapneic respiratory failure. Concepts discussed include the oxygen delivery equation, differentiating hypoxia from hypoxemia, and a discussion of V/Q mismatch and shunts. In the follow-up episode - Acute Respiratory Failure II: Clinical Management & Oxygen Therapies - we'll apply these concepts to the management of acute respiratory failure and discuss the benefits and harms of oxygen therapy.
