🚨 New #VExUS post on NephroPOCUS.com Confused by abnormal hepatic vein Doppler waveforms? This post breaks them down using physiology, making it easier to connect waveform changes to the underlying hemodynamics. 🔗nephropocus.com/2026/06/15/c… #POCUS #echofirst #Nephpearls If a component of VExUS feels difficult, the answer is to understand it better, not to eliminate it altogether. Simplification can be helpful to some extent, but oversimplification often comes at the cost of losing valuable physiological information.

ARISE FLUIDS: Vasopressors or Fluids in Early Septic Shock ca. 2026 from @NEJM #Nephpearls #AKIinICU 📌 No significant difference in days alive and out of the hospital 🏥 at day 90 between the 2 groups ⚠️But pulmonary edema 🫁 was significantly lower in the restricted fluids group (0.6% vs. 5.0%) 👉 pubmed.ncbi.nlm.nih.gov/4227… – at Nashville, TN

Hepatic vein Doppler. S>D or S<D? Answer the poll below honestly and then see the image with EKG. #POCUS #VExUS #Nephpearls

#POCUS #Nephpearls #FOAMed Modified #VExUS incorporating femoral vein Doppler (based on Joyal et al., PMID: 41931445). This approach essentially replaces intrarenal Doppler with the femoral vein stasis index and introduces a few additional modifications, including incorporation of IVC collapsibility and defining severe hepatic vein abnormality as either S-wave absence (i.e., S/D = 0) or S-wave reversal (i.e., S/D <0).

1/10 🚨 Excited to share our new multicenter study in CKJ. doi.org/10.1093/ckj/sfag080 What if “urgent-start PD” is actually… too slow? 👀 We found that many patients can safely start peritoneal dialysis within HOURS of catheter placement, not days. 🇲🇽🩺 a thread 🧵

Didn’t match in Cards? Did Crit Care freeze you out? Is that hospitalist job looking little too intellectually bankrupt? Don’t get mad, become a nephron! We have a spot in the July 2026 class that would fulfill dreams you didn’t;t know you had! DMs are open (Please RT)

(1/10): Expert clinicians understand that not all decisions are equally important - focus on the ones that move the needle the most. Decision fatigue is real. Them more decisions we make, the worse the quality. In medicine, each patient has hundreds of decisions about their care that need to be made every day. Expert clinicians focus on the few decisions that are crucial for that patient, and try to delegate other decision. A great example in the ICU: the method by which potassium is routinely replaced (oral vs. IV) is much less important than a crucial decision to extubate vs. tracheostomize a patient. Save your mental energy for the tough decisions that really move the needle.
