A new prospective multicenter cohort of 250 patients with shock examines the safety and outcomes of peripheral vasopressor administration. Extravasation events were rare and clustered only after several days of infusion, while norepinephrine use and simple physiologic markers correlated with survival. In this episode, I translate the findings into bedside guardrails—which sites and gauges to use, how to monitor, and when to pivot to a central line.

Intravenous dihydropyridine calcium channel blockers can quietly worsen oxygenation by blunting hypoxic pulmonary vasoconstriction. In this episode, we break down the bedside mechanism, which agents are implicated, who’s at highest risk (post-op atelectasis, obesity, pneumonia, focal ARDS, COPD), how soon it happens, and exactly what to do.

In this episode of Saving Lives: Critical Care Conversations, we discuss new evidence from the University of Pennsylvania that challenges how we time inotropic therapy in acute decompensated heart failure–related cardiogenic shock.

This retrospective cohort study found that patients who received inotropes within eight hours of meeting SCAI stage C criteria had a 28-day mortality of 17%, compared to 33% in those who received them later. Early inotrope use was also associated with less vasopressor dependence and quicker access to echocardiography and hemodynamic monitoring.

We’ll explore what this means for emergency and critical care practice—how recognizing hypoperfusion early, even in normotensive patients, may improve survival. We’ll also touch on the role of SCAI and SHARC criteria in timely shock identification and management.

Because in cardiogenic shock, the difference between early and delayed therapy might be the difference between life and death.

In this episode of the Saving Lives Podcast, Eddy Joe breaks down a 2025 Journal of Critical Care study examining how the choice of the internal jugular vein for initial central line placement impacts outcomes when patients later need hemodialysis catheters. You'll learn why using the left IJV first may reduce the need for repeat procedures and complications. Essential insights for optimizing central line strategy in the ICU.

In this episode of the Saving Lives Podcast, we review a July 2025 study from the Journal of Intensive Care comparing methylprednisolone and hydrocortisone for severe pneumonia treatment. The discussion focuses on how these findings may influence clinical decisions, particularly for patients with septic shock.

In this episode of the Saving Lives Podcast, we break down a 2025 study from Intensive Care Medicine that emulates a target trial on the use of sodium bicarbonate in ICU patients with metabolic acidosis. With over 6,000 patients across 12 Australian ICUs, the study reveals a small but significant reduction in mortality and RRT use with bicarbonate therapy. Tune in to learn how this could transform our clinical approach to acidemia in the critically ill patients.

In this episode of the Saving Lives Podcast, we review a 2025 NEJM-Evidence study analyzing over 21,000 cases of severe hyponatremia to determine the safest and most effective correction rates. Learn why moderate correction (8–10 mmol/L/day) may actually reduce mortality, and how central pontine myelinolysis (CPM) remains rare even with faster correction.

In this episode, we analyze a June 2025 study from the Journal of Intensive Care, which shows that lower hemoglobin levels at admission are strongly associated with worse outcomes in cardiogenic shock. We dive into the data from the FRENSHOCK registry, uncover key subgroup findings, and discuss implications for transfusion strategies. Could this shift how we manage anemia in shock?
