Unpopular ICU opinion: When a patient becomes apneic during a spontaneous breathing trial, we often declare that the patient failed the trial Maybe not. Maybe we failed the patient by stopping the trial too soon, before sedatives had worn off and the respiratory drive had a chance to return

First "clamp rounds" in NCC with my senior fellow was a huge success! But what is the NCC equivalent? Don't typically hook the EVD up to suction ☠️ Clamp, 20/open, 10/open? Not quite as slick. Either way, thanks for the idea/analogy @gbosslet.bsky.social!

Excited to share our newest work on free VPA: improving ability to predict levels with the Fraser equation. We reveal that the orig eq. is modestly accurate in an external cohort and make improvements to the eq, but confirm measurement remains ideal @cbthepharmd.bsky.social doi.org/10.1002/phar...
Standard (A) and modified (B) Bland–Altman plots representing the performance of the Fraser equation in an external cohort. In the standard Bland–Altman plot (A), the x axis represents the actual (measured) free valproate concentration while the y axis represents the difference between the Fraser predicted and the actual free valproate concentration. The solid black line represents a difference of 0 mg/L (i.e., an accurate prediction) and the dashed lines represent the 95% confidence interval of the mean difference between the predicted and actual values. Individual dots represent a single valproate concentration. In the modified Bland–Altman plot (B), the x axis represents the actual (measured) free valproate concentration, and the y axis represents the Fraser predicted free valproate concentration. The dashed line represents a perfect y = x correlation while the solid line represents the observed linear relationship between the actual and predicted concentrations. Both figures depict the worsening under-estimation as measured free valproate increases.Standard (A) and modified (B) Bland–Altman plots representing the performance of the modified Fraser equation with patient effect.In the standard Bland–Altman plot (A), the x axis represents the actual (measured) free valproate concentration while the y axis represents the difference between the Fraser predicted and the actual free valproate concentration.

Largest ever study of peripheral 23.4% NaCl with 863 administrations 😀 Some extravasation did occur, but it *didn't* lead to any major problems (tissue necrosis etc) If someone is having an ICP crisis, you should worry about their BRAIN and not their ARM - their arm will be fine #EMIMCC

ICU Facts: In my experience, in any decent size ICU (~15 beds), at any point in time, there is at least 1 patient with unequal pupils (anisocoria). People are often freaking out & rush to get a CT brain to rule out intracranial bleeding... Just think hard before reflexively doing this

Not everything labeled alternative therapy for Parkinson's is snake oil. Should we be rethinking PD therapies in 'shades of grey.' Instead of labeling treatments as either evidence-based vs. alternative, how about a spectrum of credibility grounded in science, patient perception, real-world impact.
