My issue with ScvO2 is, that it can be high while true mixed venous (SvO2) is low. It is a bad surrogate for SvO2.
So when in doubt, float a PAC and know for sure.

Thanks for sharing our review! Monitoring GI function when initiating / stepping up nutrition is key to prevent harm from too aggressive nutrition.

My question is, does it truly matter? If there’s a strong signal, shouldn’t I be able to detect it using either method (and vice versa)? And if the signal is borderline, shouldn’t I arrive at the same interpretation if my application and understanding of the statistics used are accurate?

We know RV dysfunction occurs on VV-ECMO in ARDS despite ECMO mitigating many of the traditional RV dysfunction risk factors (hypercapnia etc)

We don’t understand RV function dynamically over time on ECMO…

I don’t think that offering specific therapies out of the context of goals of care is helpful and may negatively impact the discussion and patient trajectory.

I think we want to define where a patient wants to be in 1/3/6/12 months and with what level of quality of life. We as a team can then offer specific therapies (i.e. Trach/PEG but also other options such as mech. assist devices), if and only if these therapies align with the defined goals of care.

I got tired of opening a dozen PDFs to find the ECMO pressure/flow curve I need.

So I made an app!

Choose the cannula/size and you can see the max flow for a given pressure drop. Or compare multiple different cannula.

Lmk what ya’ll think. Useful? What’s it need?

This was a fun study leveraging social media to demonstrate the high prevalence in Impella malrotation among cases shared on old Twitter.
If it's malrotated, but it works well, without suction alarms or other problems, do you change it? #cccsky #cardiosky #emimcc

Do you/does anyone know if there are data repositories with patient data, timepoints and vanco levels as well as reference clearence (maybe from observational studies)?
We could then use that to 1) validate and 2) develop new models.

What is the culture at your hospital for potassium replacement?

At most hospitals I'm at it seems to be a culture of replace to K 4.0 and the individual doctor makes the call.

No, this was just a (very simple) approximation; imagine a trial that onlynlooked atbthis group and enrolled that number of patients. As the groups are exclusive, this was a first step to get a feeling of how much of a difference there really is…

The immunocompromised group was stopped for futility. I think that these groups are not powered enough to draw any conclusion and the difference is just statistical noise. Early intubation may be warranted in these patients who can deteriorate rapidly, also for early diagnosis via bronch/lavage.

I agree, for cardiogenic NIPPV treats the not only the lungs but also the heart; this is why the results were suprising to me and I struggle with interpretation.

CVP has the same function: it is the intersection of RV function curve and venous return, so it tells you how well the RV handles the VR and if there is RV dysfunction for that given state. It is no measure of volume status or responsiveness (but probably tolerance, as is VEXUS).

11.12.2024 22:32 β€” πŸ‘ 0    πŸ” 0    πŸ’¬ 0    πŸ“Œ 0

I think of VEXUS as volume overload combined with RV dysfunction/failure. If you give a healthy person five liters of fluid, the rv might very well handle the venous return and vexus is low; only once RV dysfunction develops (either due to hypervolemia itself or for other reasons), VEXUS goes up.

As an additional remark:
Figure 2 shows the median estimated OR without borrowing, which line up better with frequentist results, although the superiority threshold was still not met. I wonder whether borrowing is valid for this group, as a cardiogenic pathology will differ from a respiratory one?

#ADAPTtrial released & the results are interesting…

Compared to SOC, Procalcitonin guided antibiotics in sepsis resulted in:
- FEWER antibiotic days: 10.7 vs 9.8 (p=0.01) BUT
- HIGHER 28 day mortality: 19.4% vs 20.9% (p=0.02) though this did not meet the pre-specified non-inferiority margin
